Kat has a dry mouth. Very little saliva is being secreted. Which type of food will be MOST affected by this? Why?

function of mucous
helps digest protein
function of HCL:
the folds on the inside of the stomach wall. These allow the stomach to expand as it fills with food.

blood is passed through an artificial kidney
what is hemodialysis
2. kidney transplant

good substances enter
what happens in reabsorption
bad substances leave
what happens in secretion
because blood cells are too large to pass through
Explain why blood cells are not found in the urine of a healthy individual.
1. excreting metabolic wastes, 2. maintaining water balance 3. maintaining proper concentrations of ions,
4. maintaining acid/base balance in the body.
List and several functions of the urinary system.
1. Filters the blood to remove wastes
2. Helps maintain water balance
3. Helps maintain acid-base balance
4. Helps maintain ion balance
