In ovulation, after expelling the oocyte the follicle becomes ____________which produces_____________.
A. corpus luteum; FSH and LH
Corpus luteum; FSH and LH: The follicle transforms into the corpus luteum after ovulation, which secretes hormones. However, FSH and LH are hormones secreted by the pituitary gland, not products of the corpus luteum.
B. corpus albicans; progesterone
Corpus albicans; progesterone: The corpus albicans is a degenerated form of the corpus luteum and is not responsible for secreting progesterone.
C. corpus albicans; estrogen and progesterone
Corpus albicans; estrogen and progesterone: The corpus albicans forms after the corpus luteum degenerates and does not produce significant levels of estrogen and progesterone.
D. corpus luteum; estrogen and progesterone
Corpus luteum; estrogen and progesterone: After ovulation, the follicle transforms into the corpus luteum, which secretes estrogen and progesterone to support the early stages of pregnancy or regulate the menstrual cycle if pregnancy does not occur.

Water output is largely controlled by varying
A. cutaneous transpiration
Cutaneous transpiration: While cutaneous transpiration (evaporation of sweat from the skin) contributes to water loss, it is not the primary mechanism controlling water output.
B. drinking
Drinking: Drinking affects water intake rather than output. It does not directly control how much water is excreted from the body.
C. urine volume
Urine volume: Urine volume is the primary means by which the body regulates water output. The kidneys adjust urine volume to maintain fluid balance and homeostasis.
D. sweating
Sweating: Sweating contributes to water loss but is not the primary mechanism for controlling overall water output compared to urine production.

___________ stimulates the interstitial cells of the testes to secrete_____________
A. Luteinizing hormone (LH); testosterone
Luteinizing hormone (LH); testosterone: Luteinizing hormone (LH) stimulates the interstitial cells (Leydig cells) of the testes to produce and secrete testosterone.
B. Follicle-stimulating hormone (FSH); androgen-binding protein (ABP)
Follicle-stimulating hormone (FSH); androgen-binding protein (ABP): Follicle-stimulating hormone (FSH) stimulates the Sertoli cells to produce androgen-binding protein (ABP), but it does not stimulate the interstitial cells to secrete testosterone.
C. Luteinizing hormone (LH); androgen-binding protein (ABP)
Luteinizing hormone (LH); androgen-binding protein (ABP): Luteinizing hormone (LH) stimulates the secretion of testosterone, not androgen-binding protein (ABP). ABP is stimulated by FSH.
D. Luteinizing hormone (LH); estrogen
Luteinizing hormone (LH); estrogen: Luteinizing hormone (LH) stimulates the secretion of testosterone, not estrogen. Estrogen is primarily produced in females and also in males in smaller amounts.

What is the function of antidiuretic hormone?
A. It stimulates angiotensin II secretion.
It stimulates angiotensin II secretion: Antidiuretic hormone (ADH) does not directly stimulate angiotensin II secretion; instead, it acts on the kidneys to promote water reabsorption.
B. It promotes water conservation.
It promotes water conservation: ADH promotes water conservation by increasing water reabsorption in the kidneys, reducing urine output, and thus helping to maintain fluid balance.
C. It inhibits salivation and thirst.
It inhibits salivation and thirst: ADH does not inhibit salivation or thirst; in fact, it can increase thirst to encourage fluid intake when dehydration is detected.
D. It stimulates hypothalamic osmoreceptors.
It stimulates hypothalamic osmoreceptors: While ADH affects hypothalamic osmoreceptors indirectly by promoting water retention, its primary function is to act on the kidneys to conserve water.
