New cards
Where does the blood enter the nephron?
afferent artenole
2
New cards
Where does blood go after afferent artenole?
a loop structure glomerulus
3
New cards
What does glomerulus?
Very high pressured blood (filtrate) squeezes from the glomerulus to selective capsule called Bowman’s capsule
4
New cards
What happens to blood (filtrate) after it passes through bowman’s capsule?
It goes into proximal convoluted tubule
5
New cards
What happens at proximal convoluted tubule?
reabsorption of filtrate. It uses Na+ pump to send minerals such as glucose back into artery that takes the blood to heart
6
New cards
What happens to filtrate after proximal tubule?
It goes through loop of henle. It’s basically a long pipe that goes from renal cortex to renal medulla
7
New cards
how does loop of henle work?
It makes the entire medulla salty.
\
right side is “not water permeable” and sends all the salts into the medulla. this saves the salts in the body from wasting
\
left side is just “water permeable” so it only keeps water there. Because the medulla is salty and doesn’t have much water concentration, the water from the left side gets sent to the medulla.
\
This is how water is reabsorbed in loop of henle

New cards
What happens to filtrate after loop of henle?
it goes to distal convoluted tubule. it just reabsorbs any last bits of water or minerals left.
9
New cards
what happens to filtrate after distal convulated tubule.
It would go to collecting duct
10
New cards
What happens after collecting duct?
It goes to medulla again. The water gets reabsorbed if there is anything left. This happens again and again until no water left and then causes the urine to leave to ureterus.
