HESI A2
HESI A2 Anatomy and Physiology Practice Test
1. Which gland is located superior to the kidney?
- A. Pituitary
- B. Adrenal
- C. Hypothalamus
- D. Pancreas
Correct answer: B
Rationale: The adrenal gland is located superior to the kidney. Each kidney is surrounded by an adrenal gland, also known as the suprarenal gland, situated on top of the kidneys. The pituitary gland (A) is located in the brain, while the hypothalamus (C) is also in the brain, above the pituitary gland. The pancreas (D) is located in the abdomen, near the stomach and small intestine, not superior to the kidney.
2. Which part of the brain controls voluntary movement?
- A. Cerebellum
- B. Cerebrum
- C. Brainstem
- D. Medulla oblongata
Correct answer: B
Rationale: The cerebrum, specifically the motor cortex located within it, is responsible for controlling voluntary movements such as walking, writing, and speaking. This region of the brain plays a crucial role in coordinating and executing voluntary muscle actions, making it the correct answer in this context. The cerebellum (Choice A) primarily coordinates balance, posture, and coordination of voluntary movements but does not control voluntary movement itself. The brainstem (Choice C) is responsible for basic life functions like breathing and heart rate, not voluntary movements. The medulla oblongata (Choice D) controls vital functions like blood pressure and breathing, not voluntary movement.
3. How many bones are in the human foot?
- A. 6
- B. 16
- C. 26
- D. 36
Correct answer: C
Rationale: The correct answer is C: 26. The human foot consists of 26 bones, including tarsal bones, metatarsal bones, and phalanges. These bones collaborate to offer support, flexibility, and stability for various activities like standing, walking, and running. Choice A (6) is incorrect as it is too low for the number of bones in the human foot. Choice B (16) is incorrect as it underestimates the actual number of bones in the foot. Choice D (36) is incorrect as it overestimates the number of bones in the human foot.
4. What is the role of the large intestine in the digestive system?
- A. Absorbing nutrients
- B. Absorbing water and forming solid waste
- C. Breaking down fats
- D. Secreting digestive enzymes
Correct answer: B
Rationale: The correct answer is B: Absorbing water and forming solid waste. The large intestine plays a crucial role in absorbing water from the remaining indigestible food matter and forming solid waste (feces) to be excreted from the body. This process helps in maintaining the body's fluid balance and eliminating waste efficiently. Choices A, C, and D are incorrect because the large intestine is not primarily responsible for absorbing nutrients, breaking down fats, or secreting digestive enzymes. These functions are mainly carried out in the small intestine.
5. Which gland is responsible for producing adrenaline?
- A. Thyroid gland
- B. Adrenal gland
- C. Pituitary gland
- D. Pineal gland
Correct answer: B
Rationale: The correct answer is the Adrenal gland. The Adrenal glands, situated on top of the kidneys, are responsible for producing adrenaline. Adrenaline is a hormone that prepares the body for the fight-or-flight response during stress. Choice A, the Thyroid gland, is responsible for producing hormones that regulate metabolism, not adrenaline. Choice C, the Pituitary gland, regulates many of the body's functions by producing various hormones but is not responsible for adrenaline production. Choice D, the Pineal gland, produces melatonin, a hormone that regulates sleep-wake cycles, and is not responsible for adrenaline production.
