Two kidneys, a ureter, a urinary bladder, and a urethra
Two kidneys, two ureters, a urinary bladder, and a urethra
Two kidneys, two ureters, two urethrae, and a urinary bladder
The connective tissue that surrounds the kidneys is the:
Hilum
Renal Capsule
Calyx
Renal Pyramid

Creatinine
Calcitriol
Calcium
The functional units of the kidneys are:
Nephrons
Renal Papilla
Minor Calyx
Major Calyx
Which of the following statements is/are TRUE?
In reabsorption, the solutes are reabsorbed across the filtration membrane into the interstitial fluid by transport processes, such as active transport and cotransport.
In secretion, solutes are secreted across the wall of the nephron into the filtrate.
Filtration is the movement of materials across the wall of the nephron into Bowman’s capsule to form a filtrate.
All statements need further evaluation.
The ascending limb of the loop of Henle functions to:
remove water and additional solutes.
help regulate aldosterone secretion.
increase the rate of active transport of Na+ in the distal tubules and collecting ducts.
dilute the filtrate by removing solutes.
