select all that apply for glomerurlar filtration

• regulated by renin-angiotensin-aldosterone system

• high = body will lose nutrients and water

• low = tubules reabsorb toxins

• constant depsite changes in blood pressure

select all that apply for the renin-angiotensin-aldosterone system

• responds to low blood flow to the kidneys

• end product is when aldosterone causes dct to retain water and sodium

• end product is increased blood pressure and increased blood vol

• response to a high blood flow to the kidneys

what is reabsorption?

• when urine is concentrated

• chemicals leave tubule and re-enter blood

• chemicals leave blood and re-enter tubule

• blood absorbs nutrients from kidneys

what does aldosterone to do the urinary system?

• reduces urine output

• results in increased blood pressure

• results in decreased blood pressure

what does atria natriuertia peptine (ANP) do to the urinary system?

• end result is decreased blood pressure

• increased urine production

• acts on renal tubules

• acts on glomerulus and increases blood flow

where does filtration occur?
