An increase of which of the following is a characteristic of respiratory alkalosis?
K+
HCO3
pH
Ca2+
The Correct Answer is C
A. K+ levels typically decrease in respiratory alkalosis due to cellular shifts in potassium as the body compensates for the pH change.
B. HCO3 (bicarbonate) levels initially decrease as a compensatory mechanism to counteract the increased pH, but it is not a direct characteristic of respiratory alkalosis.
C. pH increases in respiratory alkalosis as a result of hyperventilation, which causes excessive exhalation of CO2, leading to a higher blood pH (alkalosis).
D. Ca2+ (calcium) levels can be affected by pH changes, but a decrease in ionized calcium is more commonly seen in alkalosis, not an increase.

Correct Answer is D
Explanation
A. The ejaculatory ducts are formed by the union of the vas deferens and the seminal vesicles. Seminal fluid does not enter the ejaculatory ducts directly after leaving the epididymis.
B. The prostate gland contributes fluids to seminal fluid but is not the direct next location for the fluid after leaving the epididymis.
C. The seminal vesicle produces fluid that combines with sperm to form semen, but it is not the immediate next structure after the epididymis.
D. The vas deferens is the tube that transports sperm from the epididymis to the urethra. After leaving the epididymis, seminal fluid enters the vas deferens.
Correct Answer is B
Explanation
A. Vitamin B12 is not synthesized in the skin. It is primarily absorbed through the digestive system from dietary sources such as meat and dairy products.
B. Vitamin D is synthesized in the skin when exposed to sunlight, specifically ultraviolet B (UVB) radiation, which triggers the production of vitamin D3, a precursor to the active form of vitamin D.
C. Vitamin A is obtained from dietary sources, such as fruits and vegetables, and is not synthesized in the skin.
D. Vitamin K is primarily absorbed from food and produced by bacteria in the intestines, not synthesized in the skin.
