Proximal Convoluted Tubule |
|
Definition
Which part of the nephron does most of the tubular reabsorption of nutrients? |
|
|
Term
water, and many Negatively charged ions like Cl-, PO4-, SO4- |
|
Definition
When Na+ is actively transported back into the blood, what follows it? passively? |
|
|
Term
|
Definition
What are the capillaries that surround the nephron? |
|
|
Term
They move into the peritubular capillaries and then back out to the body. |
|
Definition
When nutrients are reabsorbed, where do they go? |
|
|
Term
Using energy (ATP) to move molecules against the concentration gradient. |
|
Definition
What is active transport? |
|
|
Term
The movement of water through a membrane from high to low concentration. |
|
Definition
|
|
Term
glucose, amino acids, fatty acids, Na+, K+, some vitamins, some minerals |
|
Definition
What nutrients are actively transported into PCT? |
|
|
Term
80% of the water that was in the filtrate in the glomerular capsule |
|
Definition
How much water is reabsorbed by the PCT? |
|
|
Term
The active transport of Na+ back into the blood makes the blood very salty and sets of a concentration gradient for water. |
|
Definition
Why does water move by osmosis in the PCT? |
|
|
Term
|
Definition
Where is the counter current mechanisms located? |
|
|
Term
|
Definition
What is pumped out of the ascending limb of the Loop? |
|
|
Term
|
Definition
What happens to the concentration of medullary area around the Loop? |
|
|
Term
The salty medulla sets up a concentration gradient that draws water out of the Loop. |
|
Definition
What is the purpose for pumping Na+ in to the medulla? |
|
|
Term
|
Definition
What is the main function of the Loop of Henle? |
|
|
Term
|
Definition
Which part of the Loop does water leave from? |
|
|
Term
|
Definition
Which part of Loop is impermeable to water? |
|
|
Term
back into the blood and out to the body |
|
Definition
Where does the water go that leaves the Loop by osmosis? |
|
|
Term
They have much longer Loops to allow more time for water reabsorption. |
|
Definition
How are the Loops of desert animals different than ours? |
|
|
Term
