Tissue fluid formation

Question 1

what is tissue fluid

Answer 1

fluid containing glucose, fatty acids, amino acids, ion s, oxygen and water which surrounds tissue

Question 2

how is tissue fluid formed

Answer 2

as blood enter the capillaries, the small diameter results in a high hydrostatic pressure meaning water, amino acids, glucose, fatty acids, ions and oxygen are forced out through the wall

Question 3

what is ultrafiltration

Answer 3

when water and small molecule are forced out through the capillary wall

Question 4

what is forced out of the capillary during ultrafilatration

Answer 4

water
amino acids
fatty acids
oxygen
glucose
dissolved minerals and salts

Question 5

what remains in the capillary during ultrafiltration

Answer 5

red blood cells
platelets
large proteins

Question 6

why is water from tissue fluid reabsorbed

Answer 6

too much liquid around tissues can cause swellings

Question 7

why are molecules forced out at the start of he capillary

Answer 7

theres a high hydrostatic force inside off the capillary

Question 8

what is the end of the capillary called where water is reabsorbed

Answer 8

the venule end

Question 9

why does water re enter the capillary and how

Answer 9

theres a low water potential in the capillary and hydrostatic pressure is lowered so water re enters at the venule end by osmosis

Question 10

how is waste from the respiring cells removed from the body

Answer 10

waste will leave the cells into the tissue fluid and will dissolve into the water.
when water is reabsorbed at the venule end of the capillary, the waste is reabsorbed with it

Question 11

what happens when equillbrium is reached at the venule end / how is excess tissue fluid removed

Answer 11

rest of tissue fluid is absorbed into the lymphatic system and drains back into the blood
