HESI A2 Anatomy and Physiology Quizlet

1. Which hormone is produced by the pancreas?

Correct answer: A

Rationale: Insulin is the correct answer. Insulin is produced by the pancreas and plays a crucial role in regulating blood glucose levels. It facilitates the uptake of glucose into cells, helping to lower blood sugar levels. Glucagon, on the other hand, is also produced by the pancreas but functions to raise blood glucose levels by stimulating the release of glucose from the liver. Somatostatin is another hormone produced by the pancreas that helps regulate the endocrine system. Cortisol, produced by the adrenal glands, plays a role in stress response and metabolism, not by the pancreas.

2. Which organ is responsible for the production of insulin?

Correct answer: C

Rationale: The correct answer is C: Pancreas. The pancreas is responsible for producing insulin, a hormone that regulates blood glucose levels by facilitating the uptake of glucose into cells. Insulin is crucial for maintaining proper blood sugar levels and is produced by specialized cells within the pancreas known as beta cells. Choices A, B, and D are incorrect because the thyroid gland, pituitary gland, and adrenal gland do not produce insulin. The thyroid gland produces hormones that regulate metabolism, the pituitary gland releases various hormones that control other glands, and the adrenal gland produces hormones like cortisol and adrenaline.

3. Which vitamin is essential for maintaining healthy skin and vision?

Correct answer: B

Rationale: Vitamin A is the correct answer. It is essential for maintaining healthy skin and vision, especially in low-light conditions. Vitamin A helps in the production of retinal pigments necessary for vision in dim light and supports skin health by promoting cell turnover and repair. Choice A, Vitamin C, is important for the immune system and collagen production but is not specifically known for maintaining skin and vision health. Choice C, Vitamin D, is crucial for bone health and immune function but is not directly related to skin and vision health. Choice D, Vitamin K, is necessary for blood clotting and bone health but does not play a significant role in maintaining healthy skin and vision.

4. To which two systems does the urethra belong?

Correct answer: B

Rationale: The urethra belongs to both the urinary and reproductive systems. In the urinary system, it functions as a passage for urine from the bladder to exit the body. In the reproductive system, it serves as a conduit for the expulsion of semen during ejaculation. Choice A is incorrect because the urethra is not part of the endocrine system. Choice C is also incorrect because the urethra is not primarily associated with the endocrine system. Choice D is incorrect as the urethra is not part of the digestive or cardiovascular systems.

5. Which organ system is primarily responsible for regulating electrolytes?

Correct answer: B

Rationale: The urinary system, specifically the kidneys, is primarily responsible for regulating electrolytes in the body by filtering and excreting excess electrolytes, such as sodium, potassium, and chloride, through urine. The kidneys play a crucial role in maintaining the body's electrolyte balance, which is essential for various bodily functions and overall health. The endocrine system regulates hormones, the lymphatic system is involved in immunity, and the nervous system controls communication in the body. Therefore, the correct answer is B, the urinary system, as it directly handles electrolyte regulation by adjusting their excretion levels.
