Which paired organ filters blood plasma, regulates electrolyte balance, and produces liquid waste?

Which hollow muscular organ expands to store liquid waste until micturition begins?

Which narrow tube uses peristalsis to carry liquid waste from each bean-shaped organ to the storage sac?

Which tube carries liquid waste from the storage sac to the outside of the body during micturition?

Which gross region is the outer layer of the kidney, just deep to the fibrous capsule?

Which gross region lies deep to the outer layer and contains cone-shaped tissue masses?

Which cone-shaped mass in the inner kidney directs filtrate-derived fluid toward the papilla?

Which funnel-shaped chamber collects fluid from the calyces before it enters a ureter?

Which capillary tuft is the site where plasma is first filtered?

Which cup-shaped nephron structure surrounds the capillary tuft and catches the first filtrate?

After filtrate leaves the capsule space, which nephron segment receives it first?

Which nephron segment descends toward the medulla and then ascends back toward the cortex?

Which convoluted segment comes after the loop and before filtrate enters a duct shared by many nephrons?

Which tube receives fluid from many upstream nephrons and carries it through the medulla toward the papilla?

Which small vessel brings blood into the capillary tuft from a cortical artery?

After blood leaves the capillary tuft, which small vessel carries it away toward peritubular capillaries?

A healthy person filters glucose but normally loses almost none in urine. What happened to the filtered glucose?

A urine sample from a healthy person should contain almost no albumin. What normally keeps this large protein out?

Hydrogen ions are moved from peritubular blood into the tubule to help regulate pH. Which urine-forming process is this?

Filtered water moves from the tubule into surrounding capillaries instead of leaving in final urine. Which process moved it?

A medication is found in final urine even though little crossed the filter. Which movement best explains its appearance?

Creatinine is small enough to enter the filtrate and is not significantly reclaimed. Why does it remain in final urine?

Red blood cells appear in urine after the filtering barrier is damaged. What failed first?

Filtered bicarbonate returns to the blood to help buffer pH. Which process describes that movement?

Plasma becomes too concentrated after heavy sweating. Which hormone rises to make collecting ducts conserve more water?

When ADH acts strongly on collecting ducts, what happens to urine volume?

Low blood pressure activates the renin-angiotensin pathway. Which hormone increases sodium reabsorption in the distal nephron?

When aldosterone rises, which ion is reabsorbed more from the distal nephron?

When aldosterone rises, which ion is secreted more into the distal nephron?

A person makes almost no ADH. What consequence follows in the collecting ducts?

After drinking a large volume of water, plasma osmolarity falls. What happens to ADH release?

Severe dehydration raises ADH. What urinalysis result would this hormone effect tend to cause?

An untreated diabetic patient's urine contains glucose. What best explains this finding?

A dipstick shows persistent albumin in urine. What is this finding called?

Leukocytes and nitrites appear together in a urine sample. Which disorder do they most strongly suggest?

A patient has severe flank pain, blood in urine, and mineral crystals forming a blockage. Which disorder matches?

Blood tests show rising urea and creatinine because nephrons cannot maintain adequate filtration. What condition does this indicate?

Which process uses a semipermeable membrane to remove urea and excess water from blood when kidneys fail?

Inflamed glomeruli allow red blood cells and protein to enter urine. Which disorder is described?

A person has intense thirst and produces very large amounts of dilute urine because ADH signaling is low. Which disorder fits?
