Correct Answer is D
Explanation
A. 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: The corpus albicans is a degenerated form of the corpus luteum and is not responsible for secreting progesterone.
C. 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: 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.
Correct Answer is B
Explanation
A. Vagina: The vagina is the canal that leads from the cervix to the outside of the body, not the structure that connects the ovary to the uterus.
B. Uterine tube: The uterine tube, also known as the fallopian tube, connects the ovary to the uterus and is where fertilization typically occurs.
C. Urethra: The urethra is the tube that carries urine from the bladder to the outside of the body. It has no role in connecting the ovary to the uterus.
D. Vas deferens: The vas deferens is a structure in the male reproductive system that transports sperm from the testes. It does not exist in the female reproductive system.
