Mass Transport- Capillaries (BV) Flashcards
1
Q
What is the diameter of a capillary?
A
1 cell thick
2
Q
What cell type is a capillary?
A
Squamous endothelial
3
Q
What do the pores between the squamous endothelial (capillary cell) allow?
A
Transfer of substances
4
Q
What are the 3 adaptations a capillary has?
A
1) Thin walls allowing a short diffusion pathway
2) Large SA to Vol ratio due to large amounts of capillaries
3) Small diameter allowing blood cells to travel in single file which slows down the blood flow
5
Q
What does the capillaries small diameter allow by slowing down blood flow?
A
More time for diffusion between capillaries and cells
