A. Vitamin D synthesis
B. Regulation of red blood cell synthesis
C. Excretion
D. Absorption of digested molecules
E. Regulation of blood volume and pressure
2. What organs compose the Urinary System?
A. Two kidneys, two urethrae, a ureter, and a urinary bladder
B. Two kidneys, a ureter, a urinary bladder, and a urethra
C. Two kidneys, two ureters, a urinary bladder, and a urethra
D. Two kidneys, two ureters, two urethrae, and a urinary bladder
It is the hormone made by the kidneys, needed for absorption of calcium phosphate, the active form of vitamin D.
A. Erythropoietin
B. Calcitriol
C. Creatinine
D. Calcium
The functional units of the kidneys are:
A. Renal papilla
B. Nephrons
C. Minor calyx
D. Major calyx
. Which of the following statements is/are TRUE? Select all that apply.
A. Filtration is the movement of materials across the wall of the nephron into Bowman’s capsule to form a filtrate.
B. In reabsorption, the solutes are reabsorbed across the filtration membrane into the interstitial fluid by transport processes, such as active transport and cotransport.
C. In secretion, solutes are secreted across the wall of the nephron into the filtrate.
D. All statements need further evaluation.
The ascending limb of the loop of Henle functions to:
A. dilute the filtrate by removing solutes.
B. remove water and additional solutes.
C. help regulate aldosterone secretion.
D. increase the rate of active transport of Na+ in the distal tubules and collecting ducts.
Approximately _____ L of filtrate enters the nephrons each day; of that volume _____% is reabsorbed in the proximal tubule.
A. 80 L and 35%
B. 180 L and 65%
C. 240 L and 85%
D. 280 L and 99%
Antidiuretic hormone (ADH), secreted by the posterior pituitary gland, passes through the circulatory system to the kidneys. ADH regulates the amount of water reabsorbed by the distal tubules and collecting ducts. When ADH levels increase, the permeability of the distal tubules and collecting ducts to water decreases, and less water is reabsorbed from the filtrate. This statement is:
A. True
B. False
C. Partially true
D. partially false
Renin is an enzyme that acts on a protein produced by the liver called (2) angiotensinogen. Amino acids are removed from, leaving (3) angiotensin I. Angiotensin I is rapidly converted to a smaller peptide called (4) angiotensin II by (5) angiotensin-converting enzyme (ACE). Angiotensin II acts on the (6) adrenal cortex, causing it to secrete aldosterone. (Correct this statement)
A. The statement is correct
B. (1) should be angiotensinogen, and (2) is renin
C. (3) should be angiotensin II, and (4) is angiotensin I
D. (6) should be adrenal medulla
Mr. Miyazaki, who is diagnosed with bipolar disorder has been drinking copious amounts of water and voiding frequently. The patient is experiencing muscle cramps, twitching, and is reporting dizziness. the nurse checks lab work for:
A. Complete blood count results, particularly the platelets.
B. Electrolytes, particularly the serum sodium.
C. Urine analysis, particularly for the presence of white blood cells.
D. EEG results
