1. Discuss the anatomical/physiological changes in pregnancy under the following: Haematological system

• A. Blood volume and plasma volume increase, red blood cells increase, erythropoietin levels decrease, and leukocyte count increases.
• B. Blood volume and plasma volume decrease, and red blood cells decrease.
• C. No changes occur in the haematological system during pregnancy.
• D. Platelet count remains constant, and no change in coagulation factors.

Correct answer: A

Rationale: During pregnancy, the haematological system undergoes changes to support the growing fetus. Blood volume and plasma volume increase to accommodate the needs of the developing baby. Red blood cells increase to support the increased oxygen demand. Contrary to the statement, erythropoietin levels actually increase to stimulate red blood cell production. Additionally, leukocyte count increases to help the mother's immune system cope with the changes during pregnancy. Choice B is incorrect as it describes a decrease in blood components, which is not the case in pregnancy. Choice C is incorrect as there are significant changes in the haematological system during pregnancy. Choice D is incorrect as platelet count can fluctuate during pregnancy, and there are changes in coagulation factors to prevent excessive bleeding.

2. Approximately how many primordial follicles are present in the cortex of the ovary at birth?

• A. 250,000
• B. 200,000
• C. 150,000
• D. 100,000

Correct answer: A

Rationale: The correct answer is A: 250,000. At birth, there are approximately 250,000 primordial follicles in the cortex of each ovary. These primordial follicles represent the reserve of oocytes that a female will have throughout her reproductive life. Choice B, 200,000, is incorrect as the number is higher. Choices C and D, 150,000 and 100,000 respectively, are also incorrect as they underestimate the actual number of primordial follicles present at birth.

3. Which of the following is not a complication of menopause?

• A. Fractures
• B. Alzheimer's disease
• C. Congestive heart failure
• D. Painful intercourse

Correct answer: C

Rationale: Congestive heart failure is not typically associated with menopause. Menopause is linked to an increased risk of fractures due to bone density loss, a higher risk of Alzheimer's disease due to hormonal changes, and painful intercourse due to vaginal dryness and thinning of tissues. While cardiovascular health can be affected by menopause, congestive heart failure is not a direct complication associated with menopause.

4. Which animal is an ovoviviparous animal?

• A. Basking shark
• B. Bonobo
• C. Blue shark
• D. None of the above

Correct answer: C

Rationale: The correct answer is the Blue shark. Ovoviviparous animals produce eggs that develop inside the body of the parent, and the offspring are born alive. The basking shark does not fall under this category as it is ovoviviparous, meaning it lays eggs that hatch inside the female's body. The bonobo is a separate species and not relevant to the question.

5. Which of the following structures is responsible for the production of sperm?

• A. Epididymis
• B. Seminal vesicles
• C. Testes
• D. Prostate gland

Correct answer: C

Rationale: The testes are the male reproductive organs responsible for the production of sperm through a process called spermatogenesis. The epididymis is a structure where sperm mature and are stored temporarily. Seminal vesicles produce a significant portion of the fluid that ultimately becomes semen, but they do not produce sperm. The prostate gland contributes additional fluid to semen but does not produce sperm. Therefore, the correct answer is the testes.
