Answer 11

pick up the fluid that leaks into your tissues from your bloodstream and return it to your circulatory system

adenoid palatine lingual

Question 32

what do tonsils do

Answer 32

tonsils combat bacteria and viruses that enter your body through your mouth.

Question 33

pressure changes in capillares

Answer 33

large hydrotatic smaller osmotic larger osmotic

Question 34

how does lymph leave capillaries

Answer 34

osmosis

Question 35

start of capillary

Answer 35

Hydrostatic pressure is higher than osmotic pressure water and small soluble molecules are forced through the capillary walls, forming tissue fluid between the cells.

Question 36

what is hydrostatic pressure

Answer 36

pressure pushing the fluid out favouring filtration, which is higher at the arterial end of the capillary.

Question 37

what is Osmotic pressure

Answer 37

pressure pushing the fluid in favouring absorption, which is higher at the venous end of the capillary

Question 38

what happens at aterial end of capillary

Answer 38

hydrostatic pressure is higher than osmotic pressure

Question 39

how is tissue fluid formed

Answer 39

water and small soluble molecules are forced through the capillary walls

Question 40

what does lymph not contain

Answer 40

Proteins and cells in the plasma are too large to be forced out

Question 41

start of cell fluid making

Answer 41

Osmotic pressure of the blood is higher than the hydrostatic pressure, and so most of the water from tissue fluid moves back into the blood capillaries

Question 42

how does cell fluid move

Answer 42

osmosis

Question 43

venous end of capillary

Answer 43

remainder of the tissue fluid is returned to the blood, via lymph vessels.

Question 44

what is tissue fluid

Answer 44

bathes the cells. Formed from plasma and blood glucose, amino acids, fatty acids, salts and oxgyeb.

Question 45

how is tissue fluid formed

Answer 45

due to high hydrostatic pressure of the blood at the arteriole end of the capillary that pushes fluid out of the blood

Question 46

how is lymph formed

Answer 46

tissue fluid fatty stubstances lymphocytes
