Tissue Fluid

Question 1

What is tissue fluid?

Answer 1

the extracellular fluid that bathes tissues

Question 2

Hydrostatic pressure

Answer 2

pressure exerted by blood

Question 3

Oncopressure

Answer 3

Pressure exerted by plasma proteins

Question 4

How does hydrostatic pressure work?

Answer 4

forces tissue fluid out of capillaries to the tissue at the arteriole end

Question 5

How does oncopressure work?

Answer 5

Draws fluid back into capillaries from the tissue at the venule end

Question 6

What is the source of hydrostatic pressure?

Answer 6

Contractions of the heart

Question 7

How do cells interact with tissue fluid?

Answer 7

take in oxygen and nutrients and release metabolic waste into it

Question 8

Why does tissue fluid formation begin?

Answer 8

At the arteriole end of the capillaries the hydrostatic pressure is greater than in the tissue fluid

Question 9

What happens due to hydrostatic pressure being higher in the capillaries?

Answer 9

Fluid is forced out of fenestrations forming tissue fluid

Question 10

What happens to the pressure in the capillaries due to the formation of tissue fluid?

Answer 10

it decreases so its lower at the venule end

Question 11

What happens in the venule due to fluid loss?

Answer 11

an increase in concentration of plasma proteins means water potential is lower than in the tissue fluid

Question 12

At the artierial end, which pressure is higher?

Answer 12

Hydrostatic
