Module 4.2 - Heat Transport in Tissues

Question 1

Assumptions on energy balance for vascularized tissue (2)`

Answer 1

1. Principal heat exchange betw blood and tissue takes place in capillaries
2. Flow of blood in capillaries occurs in same direction (ie. there is no need to consider directionality of blood flow in different capillaries)

Question 2

Synovial fluid

Answer 2

Body fluid

Question 3

Why is the thermal conductivity in skeletal muscle (k) higher than in the dermis, fat, and epidermis?

Answer 3

Skeletal muscle produces a lot of heat during exercise because it’s not very efficient at converting ATP (adenosine tri-phosphate) into work.

Question 4

Why do the core-skin models for heat transfer not reflect reality?

Answer 4

They are very simplistic and do not consider other components in the body that conduct heat, such as organs.
