Kidney Filtration and Reabsorption Check In

What substances are pushed through the differentially permeable cell membrane of the glomerulus into the glomerular capsule during glomerular filtration?

• Carbon dioxide, urea, uric acid, and creatinine

• Glucose, amino acids, salts/ions (Na+, Ca+, Cl-), water, and some wastes

• Red blood cells, platelets, white blood cells, and plasma proteins

• Lipids, proteins, carbohydrates, vitamins, and hormones

Where does the reabsorption of glucose, amino acids, salts/ions (Na+, Ca+, Cl-), water, and some wastes back into the blood begin?

• Proximal convoluted tubule

• Collecting duct

• Loop of Henle

• Distal convoluted tubule

What substances are selectively reabsorbed at the loop of Henle?

• Carbon dioxide and urea

• Creatinine and potassium ions

• Glucose and amino acids

• More water and salts/ions (Na+)

What process moves substances that have snuck into the blood, back into the filtrate at the distal convoluted tubule?

• Renal excretion

• Tubular secretion

• Glomerular filtration

• Tubular reabsorption

What creates a high pressure within the glomerulus, allowing substances to move from high pressure to low pressure during glomerular filtration?

• The afferent arteriole being narrower than the efferent arteriole

• The loop of Henle being highly permeable to water

• The efferent arteriole being narrower than the afferent arteriole

• The glomerular capsule being impermeable to small substances
