Which part of the male productive tract is cut and sealed as part of a vasectomy?
Epididymis
Tunica albuginea
Efferent ductules
Ductus deferens
The Correct Answer is D
A. Epididymis: The epididymis is where sperm mature and are stored. It is not cut during a vasectomy.
B. Tunica albuginea: This is the connective tissue surrounding the testis, not part of the sperm-carrying duct system.
C. Efferent ductules: These ducts transport sperm from the testis to the epididymis, but they are not cut during a vasectomy.
D. Ductus deferens: The ductus deferens (vas deferens) is the tube that carries sperm from the epididymis to the ejaculatory duct. It is cut and sealed during a vasectomy, preventing sperm from reaching the urethra.

Correct Answer is C
Explanation
A. Aldosterone hormone: Aldosterone affects sodium and potassium reabsorption, increasing water retention indirectly, but it does not directly increase water permeability in the collecting ducts.
B. Atrial natriuretic peptide hormone: This hormone decreases blood volume by inhibiting sodium reabsorption, leading to more water excretion, not reabsorption.
C. Antidiuretic hormone (ADH): ADH increases the permeability of the collecting ducts to water, allowing more water to be reabsorbed into the bloodstream.
D. Parathyroid hormone: This hormone primarily regulates calcium levels, not water permeability.
