___ is the process at the start of nephron (glomerulus) that takes only blood plasma from the blood

• filtration
• reabsorption
• secretion

If you drink a lot of water, in order to keep homeostatic balance, whatever you don't sweat out will _____

• stay absorbed in your blood and cause low blood pressure
• stay absorbed in your blood and thereby decreasing your urine output
• be excreted by kidneys thereby increasing your urine output
