1. Absorption is the ability to exhale carbon dioxide.

• A. TRUE
• B. FALSE
• C. Not Sure
• D. None of the above

Correct answer: B

Rationale: Absorption is the process of taking in substances such as nutrients or gases. Exhaling carbon dioxide is a part of the process of respiration, not absorption. Therefore, the statement that absorption is the ability to exhale carbon dioxide is false. Choice A is incorrect because absorption does not involve exhaling carbon dioxide. Choice C is incorrect as the concept of absorption can be clearly defined. Choice D is also incorrect as there is a definitive answer to the statement provided.

2. What is the term for the upper midportion of the abdomen?

• A. hypochondriac
• B. iliac
• C. hypogastric
• D. epigastric

Correct answer: D

Rationale: The correct answer is "epigastric." The epigastric region is located in the upper midportion of the abdomen, between the hypochondriac regions on either side. Choice A, "hypochondriac," refers to the upper lateral regions of the abdomen beneath the ribs. Choice B, "iliac," pertains to the lower lateral regions of the abdomen. Choice C, "hypogastric," is the lower central region of the abdomen.

3. Calcium concentration in the blood is controlled by which of the following glands?

• A. Hypothalamus gland
• B. Thyroid gland
• C. Pituitary gland
• D. Parathyroid glands

Correct answer: D

Rationale: The correct answer is Parathyroid glands. The parathyroid glands are responsible for regulating calcium levels in the blood by secreting parathyroid hormone (PTH). PTH helps increase calcium levels in the blood when they are too low. The other glands listed, such as the Hypothalamus, Thyroid, and Pituitary glands, do not directly control calcium concentration in the blood.

4. Which of the following is produced by the prostate gland?

• A. testosterone
• B. fluid to lubricate the head of the penis
• C. substance to enhance sperm mobility
• D. Gonadotrophin-releasing hormone

Correct answer: B

Rationale: The correct answer is 'fluid to lubricate the head of the penis.' The prostate gland produces a milky fluid that makes up part of the seminal fluid, which helps to nourish and transport sperm. Testosterone is produced mainly by the testes, not the prostate gland. While the prostate gland does contribute to sperm mobility, its primary function is to produce the fluid that lubricates the penis during ejaculation. Gonadotrophin-releasing hormone is produced by the hypothalamus and regulates the release of hormones from the pituitary gland.

5. In the early days, healers transitioned from superstition and magic to using natural chemicals in the field of medicine.

• A. True
• B. False
• C. Not Sure
• D. None of the above

Correct answer: A

Rationale: The statement is true. The field of medicine evolved as early healers moved away from superstition and magic, instead focusing on natural chemicals to treat illnesses. This transition marked a shift towards a more scientific and evidence-based approach to healthcare. This historical transition is well-documented in the evolution of medicine. Choice B is incorrect because the statement accurately reflects the historical development of medicine. Choice C is incorrect as the historical transition from superstition to natural chemicals is a well-documented aspect of the evolution of medicine. Choice D is incorrect as the statement provided is true.
