Q

(tissue fluid) at the arterial end of the capillary hydrostatic pressure is what?

A

high - 4.6

17
Q

(tissue fluid) the high hydrostatic pressure at the arterial end does what?

A

forces blood out of the capillary

18
Q

(tissue fluid) the oncotic pressure is what at the arterial end?

A

lower than the hydrostatic

19
Q

(tissue fluid) at the venous end what is the hydrostatic pressure?

A

low - 2.3

20
Q

(tissue fluid) what is the oncotic pressure at the venous end?

A

3.3 - higher than hydrostatic

21
Q

(tissue fluid) at the venous end oncotic pressure is higher than hydrostatic so the fluid does what?

90%

23
Q

(lymph) 10% of the fluid that doesn’t go back to the blood goes where?

A

into lymph capillaries

24
Q

(lymph) lymph has less what?

A

oxygen and nutrients

25
Q

(lymph) lymph has fatty acids from where?

A

the villi of the small intestine

26
Q

(lymph) lymph capillaries join to form what?

A

lymph vessels

27
Q

(lymph) the lymph is moved by what?
