HESI A2 Anatomy and Physiology Quizlet

1. Which gland is located on top of the kidneys?

Correct answer: A

Rationale: The correct answer is the Adrenal gland. The adrenal glands are located on top of the kidneys. They produce hormones such as adrenaline and cortisol, which play essential roles in regulating metabolism, immune response, and stress in the body. The Thyroid gland, Pineal gland, and Pancreas are not located on top of the kidneys. The Thyroid gland is located in the neck, the Pineal gland in the brain, and the Pancreas behind the stomach.

2. Which part of the brain is responsible for controlling balance and coordination?

Correct answer: A

Rationale: The cerebellum is the correct answer. It is responsible for controlling balance, coordination, and fine motor movements. The cerebrum is mainly associated with higher brain functions such as thinking and decision-making, not specifically balance and coordination. The brainstem is responsible for basic life functions like breathing and heartbeat, while the medulla oblongata is involved in regulating autonomic functions like breathing, heart rate, and blood pressure. Therefore, the cerebellum stands out as the key brain region for maintaining physical control and movement.

3. The epidermis is classified as which of the following?

Correct answer: B

Rationale: The epidermis is classified as a tissue, more specifically as a layer of cells that form the outermost part of the skin. It is composed of multiple layers of cells that protect underlying tissues and regulate various functions related to the skin. Choice A, Cell, is incorrect because the epidermis is not just a single cell but rather a collection of cells. Choice C, Organ, is incorrect because the epidermis is not an organ on its own but rather a part of an organ, the skin. Choice D, System, is incorrect because the epidermis is not a system but rather a component of the integumentary system.

4. The hypothalamus is part of the ___________.

Correct answer: B

Rationale: The hypothalamus is a small region of the brain that plays a crucial role in linking the nervous system to the endocrine system. It helps regulate various bodily functions by releasing hormones that signal the pituitary gland to release other hormones that control metabolism, growth, reproduction, sleep, and other important processes. Therefore, the hypothalamus is a key component of the endocrine system. Choices A, C, and D are incorrect because the hypothalamus is not part of the cardiovascular, respiratory, or lymphatic systems.

5. What is the primary function of the small intestine in the digestive system?

Correct answer: B

Rationale: The correct answer is B: To absorb nutrients. The small intestine's main role in the digestive system is to absorb nutrients from digested food. It has specialized structures, such as villi and microvilli, that increase its surface area for efficient absorption of nutrients into the bloodstream. Choice A is incorrect because the small intestine does not primarily secrete digestive enzymes; that role is mainly carried out by the pancreas and other digestive organs. Choice C is incorrect because the small intestine primarily absorbs nutrients rather than breaking down food. Choice D is incorrect because the absorption of water primarily occurs in the large intestine, not the small intestine.
