Reproductive System Exam Quizlet
1. 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.
2. Total Fertility Rate is at 6.2 births per woman in Zambia. This implies that:
- A. Zambian women will give birth to 6.2 children on average during their childbearing years.
- B. 6.2% of the time she will be pregnant during her childbearing years.
- C. 6.2% of her deliveries will not be successful.
- D. 6.2% of women will require medical intervention to become pregnant.
Correct answer: A
Rationale: A Total Fertility Rate of 6.2 means that a woman will give birth to an average of 6.2 children during her childbearing years. The correct answer is A as it accurately reflects the concept of Total Fertility Rate. Choice B is incorrect as it misinterprets the concept by equating it to a percentage of time being pregnant. Choice C is incorrect as it does not relate to the Total Fertility Rate but rather to the success rate of deliveries. Choice D is incorrect as it introduces the idea of medical intervention, which is not directly related to the Total Fertility Rate.
3. What phase corresponds with the luteal phase?
- A. Menstrual phase
- B. Follicular phase
- C. Secretory phase
- D. Menstrual phase
Correct answer: C
Rationale: The luteal phase corresponds with the secretory phase. During the menstrual cycle, the luteal phase follows ovulation and is characterized by the development of the corpus luteum, secreting progesterone to prepare the endometrium for a potential pregnancy. The other choices, menstrual phase (A), follicular phase (B), and the repeated choice of menstrual phase (D) do not align with the luteal phase and its functions.
4. Each breast is situated on each side of the sternum and extends between the:
- A. 1st and 6th rib
- B. 2nd and 6th rib
- C. 3rd and 6th rib
- D. 4th and 6th rib
Correct answer: B
Rationale: The correct answer is B: 2nd and 6th rib. Each breast is situated between the 2nd and 6th ribs. This anatomical location is important for understanding breast examination techniques and identifying potential abnormalities. Choices A, C, and D are incorrect because the breasts do not extend as far as the 1st, 3rd, or 4th rib, respectively. Understanding the precise anatomical location of structures is crucial in healthcare to ensure accurate assessments and interventions.
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.
