↑ Coverage determines the chance to hit this body part. It refers to the percentage of the super-part that this part covers, before its own sub-parts claim their own percentage. For example, if the base coverage of the super-part is 100%, and the coverage of the part is 20%, 20% of hits would hit the part, and 80% the super-part. If the part had its own sub-part with 50% coverage, the chances would be 10% sub-part, 10% part, 80% super part.
↑ Target Chance is the actual chance for each part to be be selected as the target when each part's coverage has been taken into account(I.E. Neck covers 7.5% of Torso but Head covers 80% of Neck so it actually has only a 1.5% chance to be selected). This is not pure hit chance, as different damage types propagate damage in different ways.

Body Parts (Detailed)

All the body parts are listed below in more detail. This includes some things to note, some quirks or special things about body parts, and the full names/descriptions of body parts that have multiples of them in the same body (eg. right lung and left lung).

Head

Health: 30
Lethal if destroyed/removed.

Container of the skull, eyes, ears, nose, and jaw. Technically, you don't need the head itself to live (rather you need the contents of the head, like the brain, to live).

While humans can survive headshots, damage to the brain is still a serious issue. A single gunshot typically destroys the brain due to its low health, but a slightly lower power weapon like the assault rifle can hit the brain and not kill the colonist. However, brain tissue always scars and sufficient damage may render a colonist unconscious forever.

Skull

Health: 30
Lethal if shattered.

Contains the brain. It's worth noting that an injury cannot hit the brain without hitting the skull as well. Lethal if destroyed, since it holds the brain.

Brain

Health: 10
Lethal if destroyed/removed.

The most important organ of a colonist. It's required for consciousness, sight processing, hearing processing, moving, and working.

Eyes

Health: 10

Includes :

Right Eye
Left Eye

Eyes are required for seeing. Eyes have a high chance to be permanently injured (scar) when damaged. Lost or damaged eyes can be surgically replaced with bionic eyes, though they are rather expensive.

Ears

Health: 10

Includes :

Right Ear
Left Ear

Ears are required for hearing things in the world. Losing both ears results in total deafness. Hearing helps in trade price improvement. Damaged or lost ears can be replaced with a bionic ear

Loud noises like gunshots do not inflict pain or damage on the ears.

Nose

Health: 10

Though required for smelling, there is no smelling system in place for RimWorld. A damaged or destroyed nose is the least of your worries in terms of injury, but will cause the colonist to become disfigured, which will cause -15 opinion from all other colonists.

Jaw

Health: 20

Required for eating, colonists are left unable to eat if they lose their jaw. Lost or damaged jaws can be surgically replaced with dentures. The jaw is also required for socializing.

Torso

Health: 40
Core Part
Lethal if destroyed

The torso is the core part of a colonist. It is a container for the rest of the major organs of a colonist, and destroying it effectively destroys/disconnects the rest of the colonist's organs. A majority of human characters will die from torso injury/destruction long before they die of anything else.

Neck

Health: 30
Lethal if destroyed/removed.

Technically part of the torso, it connects the head to the torso. Neck damage makes colonists bleed out very fast. Loss of the neck results in death, due to disconnecting the brain from the core part, the torso.

Clavicle

Health: 25

Includes :

Right Clavicle
Left Clavicle

The clavicles are the bones between the neck and shoulder, and are required for the colonist's arms to function. Shattering a clavicle is equivalent to actually losing the arm in terms of functionality.

Spine

Health: 35

Colonists need their spine for moving and working. Shattering the spine results in complete paralysis, presumably below the neck. The only way to restore functionality is by administering Luciferium over time, or installing a Bionic spine.

Pelvis

Health: 25

The pelvis is critical for moving, and shattering it results in paralysis below the waist. Colonists are completely unable to walk from this sort of injury, and will be forced to be bed-bound for the rest of their life. There is currently no way to repair or replace a shattered pelvis, and euthanizing the colonist is currently the only thing you can do.

Sternum

Health: 25

Front part of the rib cage. Like ribs, it currently only causes pain if destroyed.

Rib

Health: 15

Includes :

Rib x 12

Colonists have 12 ribs, so damage/loss of a rib is relatively harmless. Loss of a rib only results in pain.

Lung

Health: 20

Includes :

Right Lung
Left Lung
Lethal if both lungs lost.

Colonists have two lungs, a right lung and left lung. Currently, colonists can breathe and survive fine with just one lung. Losing both lungs is instantaneous death, as the colonist will immediately suffocate. Lungs tend to bleed out very fast when damaged, but are generally survivable injuries. Lungs can be harvested and transplanted, so a damaged or lost lung can be replaced. Pirate traders occasionally have organs for sale.

Stomach

Health: 30

Stomachs act like colonists' jaws in many ways, as the loss of the stomach results in an inability to eat. A colonist without a stomach can still eat, though very slowly. Gut worms can infect the stomach and increase hunger and pain.

Heart

Health: 20

The heart is needed for blood pumping in colonists. Complete destruction of the heart results in instant death.

Worth noting that, like the brain, the heart always scars,^[1] and never heals naturally. This is less severe than a brain scar, which could put colonists and other characters into a permanent coma, but still a very serious injury. Hearts can be harvested and transplanted - albeit at the cost of the donor's life - so a damaged heart can be replaced. Slave traders occasionally have these organs for sale.

Kidney

Health: 20

Includes :

Right Kidney
Left Kidney
Lethal if both lost

Kidneys are required for blood filtration. Like lungs, losing one isn't life-threatening, but losing both results in death. A loss of blood filtration efficiency also results in drastically reduced disease resistance, so kidney damage can lead to colonists that survive a firefight later dying of malaria or the flu. Kidneys can be harvested and transplanted, so a damaged or lost kidney can be replaced. Slave traders occasionally have these organs for sale.

Arm

Health: 30

Includes :

Right Arm
Left Arm

Arms are required for working, and are containers for the hands and subsequent bones. One-armed colonists can still work, though much slower. A lost or damaged arm can be replaced either with a simple prosthetic or a more expensive bionic arm. Simple versions are only 50% as effective whereas bionic versions are 20% more efficient than a natural limb. Any arm prosthetic will completely replace the arm, including hands and fingers.

Humerus

Health: 25

Includes :

Right Humerus
Left Humerus

Upper bones of the arm. While these are usually minor injuries (as bone injuries never scar), shattering one's humerus is equivalent to losing the entire arm, with a complete loss of functionality for the arm, meaning the arm can no longer do work. Definitely not funny.

Radius

Health: 20

Includes :

Right Radius
Left Radius

Forearm bones, similar to humerus in terms of injury and shattering, with a loss of working ability for the appropriate arm if shattered.

Hand

Health: 20

Includes :

Right Hand
Left Hand

Hands are the containers for fingers, and are required for working. One handed colonists can still work fine, just slower. A lost or damaged hand can be replaced with a power claw salvaged from an incapacitated Scyther. The claw is only 90% as effective as a natural hand, but provides increased damage in combat.

Fingers

Health: 7

Includes :

Right Thumb
Right Index Finger
Right Middle Finger
Right Ring Finger
Right Pinky
Left Thumb
Left Index Finger
Left Middle Finger
Left Ring Finger
Left Pinky

Colonists have ten fingers, consisting of the thumbs, index, middle, ring, and pinky fingers. Loss of any of these results in a small penalty to working (though it's usually so small it's difficult to notice).

Losing a finger will cause the colonist to lose 10% manipulation.

Leg

Health: 30

Includes :

Right Leg
Left Leg

Every colonist has two legs. A lost or damaged leg can be replaced either with a simple prosthetic or a more expensive bionic leg. Simple versions are only 85% as effective whereas bionic versions are 40% more efficient than a natural limb. If a prosthetic can't be located, peg legs are also available, but they are only barely functional. Any leg prosthetic will completely replace the entire leg, including the feet and toes.

Tibia

Health: 25

Includes :

Right Tibia
Left Tibia

Lower leg bone (aka shinbone), required for moving. When shattered, results in a complete loss of function of the leg containing the bone.

Femur

Health: 25

Includes :

Right Femur
Left Femur

Upper leg bone between hip and knee, the same in terms of injury as the tibia, with a loss of moving capacity on being shattered.

Foot

Health: 20

Includes :

Right Foot
Left Foot

Humans have two feet, needed for moving. There are also the container for the toes.

Toes

Health: 7

Includes :

Right Little Toe
Right Fourth Toe
Right Middle Toe
Right Second Toe
Right Big Toe
Left Little Toe
Left Fourth Toe
Left Middle Toe
Left Second Toe
Left Big Toe

Probably the most minor injuries a colonist can have would be to the toes. They hurt a colonist's moving capacity by a small amount.

Losing a toe will cause a colonist to lose 4% of its moving capacity. Even on the rimworlds, stubbing your toe is still as painful.

Replacements

As there are many ways to loose or permanently impair body parts, there are also several ways to replace them. The Options vary in difficulty of crating/acquiring, but most importantly in how effective the replacement part will be.

Part Efficiency

A un-injured, naturally grown body part has a efficiency of 100%. Replacement options however can have very variable efficiency, going from 60% to above 100%.

Replacement parts come in rough tech levels, which have a part efficiency range. Parts that were available on the previous tech level tend to have higher part efficiency then those that become first available.

Wooden Parts

The low tech variant even available for Tribals. It also has the smallest group of available replacement parts, being only rarely an option. Part efficiency varies from 60-80%.

A word of warning: Installing those still counts as a operation that can be botched and requires anesthetics.

Prosthetics

Prosthetics roughly equal replacement parts available or very likely is the early 21st century. They only require Steel and Components to build. They can be built on a Machining Table after, the Prosthetic research.

Part efficiency varies from 50-85%, depending on part.

Harvested Parts

As RimWorld has no concept of body part rejection or the difficulty of the implantation, this is a surprisingly low-tech option. All harvested body parts have 100% efficiency. For most organs, this is the earliest available replacement option. It only requires medicine as anesthetic.

Operations not specifically aimed at harvesting (like Amputation or installing replacements) generally do not yield these body parts - they have to be intentionally harvested. Both the "donor" and the colony as a whole may receive negative Mood for a harvesting operation. There is no voluntary donation mechanic.

Traders may have body parts not normally available for harvesting (like limbs) and generally sidestep any mood effects for acquiring the body part.

Bionics

Bionics are the cybernetics as they are found in Science Fiction. Bionics require Plasteel, Advanced Components and Bionics research, as well as generally a Fabrication bench.

They generally have 125% part efficiency, making them straight upgrades for most body parts. If there is no replacement parts between harvested and bionic parts, the organ can not be sensibly replaced (like a brain) or replacements offer no benefit.

Specialized Bionics

These bionics tend to be more simple replacements than upgrades. They often improve one ability drastically and in unique ways, but always come with some sort of downside. These downsides include vulnerability to EMP, a below 100% part efficiency (which somewhat lessens the primary bonus), cancer and other side effects.

Many of these are tied to the Royalty DLC, but a few have been available in the base game for a long time.

Archotech

At 150% a plain upgrade over Bionics. However they can not be crafted, only acquired via quests.
