1. The gland located on top of the kidneys responsible for regulating blood pressure and electrolyte balance is the:

Correct answer: C

Rationale: The gland located on top of the kidneys responsible for regulating blood pressure and electrolyte balance is the adrenal gland. The adrenal gland produces hormones such as cortisol and aldosterone, which play a crucial role in regulating blood pressure and electrolyte balance in the body. The other choices, thyroid gland (choice A), pituitary gland (choice B), and parathyroid gland (choice D), do not have a primary role in regulating blood pressure and electrolyte balance. The thyroid gland is responsible for regulating metabolism, the pituitary gland controls various endocrine functions, and the parathyroid gland regulates calcium levels in the body.

2. Which of the following organs does not belong with the others?

Correct answer: B

Rationale: The correct answer is B - Stomach. The stomach is primarily involved in the digestive system, breaking down food through digestion. In contrast, the thyroid gland, intestines, and pancreas are part of the endocrine system or digestive system, involved in hormone production, nutrient absorption, and digestion. Therefore, the stomach stands out as the odd one in this group as it is the only organ specifically dedicated to digestion, while the others have dual roles or different primary functions.

3. Which type of cells make up the myelin sheaths?

Correct answer: A

Rationale: The correct answer is A: Glial cells. Glial cells are responsible for producing the myelin sheaths that surround and insulate nerve cells in the central and peripheral nervous systems. Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system are types of glial cells that form the myelin sheaths. Choice B, dendrites, are not involved in forming myelin sheaths; they are extensions of neurons that receive signals. Choice C, melanocytes, are cells responsible for producing melanin, not myelin. Choice D, squamous cells, are flat epithelial cells found in various tissues but are not involved in myelin sheath formation.

4. Convert 0.1 liter to milliliters.

Correct answer: B

Rationale: To convert 0.1 liters to milliliters, you need to multiply by 1000, not 10000. Therefore, 0.1 liter converts to 100 ml. Choice A (10 ml) is incorrect because it is the equivalent of 0.01 liter. Choice C (1000 ml) is incorrect as it represents 1 liter. Choice D (1 ml) is significantly less than the correct conversion.

5. Which system's primary function is protection, sensory reception, thermoregulation, osmoregulation, insulation, and vitamin D absorption?

Correct answer: B

Rationale: The correct answer is the Integumentary system (Option B). The integumentary system, which includes the skin, hair, nails, and glands, serves various functions such as providing protection against external factors, sensory reception, regulating body temperature (thermoregulation), maintaining water balance (osmoregulation), insulating the body, and absorbing vitamin D from sunlight. The nervous system (Option A) is responsible for transmitting signals throughout the body. The endocrine system (Option C) produces and secretes hormones to regulate bodily functions. The digestive system (Option D) is involved in breaking down food for nutrient absorption. Therefore, the primary functions described in the question align with those of the integumentary system, making it the correct choice.
