Body parts volume

This data is useful as it gives us some rough rough idea about things such as the volume of blood in a given body part, if we make the simple approximation that blood quantity is homogeneous in the body (obviously untrue, but good enough for SS3D).

• Average volume of a human body : 65 L https://bionumbers.hms.harvard.edu/bionumber.aspx?s=n&v=3&id=109718

• Volume of intestines : https://bionumbers.hms.harvard.edu/bionumber.aspx?s=n&v=2&id=111759

• Volume of Heart, lungs and liver : https://bionumbers.hms.harvard.edu/files/Mass%20and%20volume%20of%20the%20organs%20of%20the%20human%20body.pdf

• Volume of stomach : https://en.wikipedia.org/wiki/Stomach

• Volume of limbs :

Using those sources, we can approximate the volume for each body part :

For the torso and its organs :

• Total Torso = 50 % of 65L = 32.5L

• Heart = 0.3 L

• Lower and upper Intestines = 1 L each

• Liver = 1.5L

• Lungs = 0.7L each

• Stomach = 2L

• Total volume of Torso without organs = 32.5 - 0.3 - 1 - 1 - 1.5 - 0.7*2 - 2 = 25.3 L

For the limbs :

• left/right arm = 4% of 65 L = 2.6L

• left/right hand = 1% of 65 L = 0.65L

• left/right leg = 14% of 65 L = 9.1L

• left/right foot = 2% of 65 L = 1.3L

For the head and its organs :

• total head = 8% of 65L = 5.2L

• Brain = 1.3L

• Eyes = 0.03 L each

• head without organs = 5.2 -1.3 - 0.06 = 3.8L
