1. What does Bidder's canal receive?

• A. Eggs
• B. Sperms
• C. Ammonia
• D. Oxygenated blood

Correct answer: B

Rationale: Bidder's canal is a part of the male reproductive system and receives sperm from the testes. The other choices are incorrect because Bidder's canal is not associated with receiving eggs, ammonia, or oxygenated blood.

2. _______ is a lytic enzyme released by the sperm.

• A. Hyaluronidase
• B. Trypsin
• C. Helicase
• D. None of the above

Correct answer: A

Rationale: Hyaluronidase is the correct answer. It is a lytic enzyme released by the sperm to help penetrate the egg's protective layer. Trypsin is a digestive enzyme produced in the pancreas, not released by sperm. Helicase is an enzyme involved in DNA replication, not released by sperm. 'None of the above' is incorrect as hyaluronidase fits the description provided in the question.

3. When does missed abortion occur?

• A. The fetus dies and is retained in utero with the placenta and membranes.
• B. All products of conception are expelled with minimal bleeding.
• C. The cervix remains closed, and the products of conception remain in the uterus.
• D. The cervix remains closed, but there is heavy bleeding.

Correct answer: C

Rationale: Missed abortion occurs when the cervix is closed, and the products of conception remain in the uterus. Choice A describes a missed abortion, not choice C. Choice B describes a complete abortion. Choice D describes a threatened abortion, where the cervix remains closed but there is heavy bleeding.

4. Polymenorrhoea is defined as:

• A. Menstruation that occurs at an interval less than 35 days
• B. Menstruation that occurs at an interval greater than 35 days
• C. Menstruation that occurs at an interval less than 21 days
• D. Menstruation that occurs at an interval greater than 21 days

Correct answer: C

Rationale: Polymenorrhoea is defined as menstruation that occurs at intervals shorter than 21 days. Choice A is incorrect because it describes menstruation at intervals less than 35 days. Choice B is incorrect as it describes menstruation at intervals greater than 35 days. Choice D is incorrect as it describes menstruation at intervals greater than 21 days.

5. 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.
