Question 1 of 5

When an individual is under stress, hormones are released. Which of the following is not one of the locations in which hormones are released when under stress?

Correct Answer: D

Rationale: Step-by-step rationale for why choice D (Parathyroid) is correct: 1. Parathyroid glands are not directly involved in the stress response. 2. When under stress, hypothalamus triggers the release of hormones from posterior pituitary and adrenal cortex. 3. Parathyroid regulates calcium levels, not stress hormones. 4. Choices A, B, and C are all directly involved in the stress response. In summary, the parathyroid gland is not a part of the stress response system, unlike the posterior pituitary, hypothalamus, and adrenal cortex.

Question 2 of 5

What is the function of the stomach in digestion?

Correct Answer: B

Rationale: The correct answer is B: To break down food. The stomach plays a crucial role in digestion by using acid and enzymes to break down food into smaller particles for further processing in the intestines. Absorbing nutrients (A) primarily occurs in the small intestine, not the stomach. While the stomach does secrete digestive enzymes (C), its main function is not solely to secrete enzymes but to physically and chemically break down food. Storing glucose (D) is not a primary function of the stomach in digestion; glucose storage mainly occurs in the liver and muscles.

Question 3 of 5

Which structure is part of both the male reproductive system and the urinary system?

Correct Answer: B

Rationale: The correct answer is B: Urethra. The urethra is a structure that is part of both the male reproductive system and the urinary system. It serves as a passage for both urine and semen to exit the body. The other choices, A: Testes, C: Prostate, and D: Penis, are specific to the male reproductive system only and do not play a role in the urinary system. The testes are responsible for sperm production, the prostate gland produces seminal fluid, and the penis is involved in sexual intercourse and ejaculation. The urethra, on the other hand, is a shared structure that connects both systems, making it the correct answer.

Question 4 of 5

When an individual is under stress, hormones are released. Which of the following is not one of the locations in which hormones are released when under stress?

Correct Answer: D

Rationale: Step-by-step rationale for why choice D (Parathyroid) is correct: 1. Parathyroid glands are not directly involved in the stress response. 2. When under stress, hypothalamus triggers the release of hormones from posterior pituitary and adrenal cortex. 3. Parathyroid regulates calcium levels, not stress hormones. 4. Choices A, B, and C are all directly involved in the stress response. In summary, the parathyroid gland is not a part of the stress response system, unlike the posterior pituitary, hypothalamus, and adrenal cortex.

Question 5 of 5

What is the function of the skin in protecting the body?

Correct Answer: B

Rationale: The correct answer is B: To protect against pathogens. The skin acts as a physical barrier that prevents harmful pathogens from entering the body. It also contains specialized immune cells that help to fight off infections. Vitamin D production (choice A) primarily occurs in the skin but is not the main function of skin protection. Storing nutrients (choice C) is not a primary function of the skin. While the skin does play a role in thermoregulation (choice D), its main function in protecting the body is to defend against pathogens.
