HESI A2 Anatomy and Physiology Quizlet 2024

1. The dorsal body cavity is _______ to the ventral body cavity.

Correct answer: C

Rationale: The dorsal body cavity is positioned on the back (posterior) side of the body, whereas the ventral body cavity is on the front (anterior) side. Therefore, the dorsal body cavity is posterior to the ventral body cavity. Choice A, 'medial,' refers to a position toward the midline, not the back or front. Choice B, 'deep,' is a term used to describe structures that are further away from the surface, not their position in relation to each other. Choice D, 'anterior,' is the opposite of 'posterior' and refers to the front side of the body, not the back.

2. What is the main function of the large intestine?

Correct answer: B

Rationale: The main function of the large intestine is the absorption of water and electrolytes from indigestible food residues, helping to form solid waste (feces) for elimination. It mainly reabsorbs water and compacts the remaining material into feces, playing a crucial role in maintaining fluid balance in the body. Choices A, C, and D are incorrect because absorption of nutrients primarily occurs in the small intestine, secretion of digestive enzymes mainly occurs in the stomach and small intestine, and breaking down fats primarily occurs in the small intestine with the help of bile from the liver and enzymes.

3. What is the primary function of the liver?

Correct answer: A

Rationale: The primary function of the liver is to detoxify harmful substances in the blood. While the liver also produces bile, which aids in digestion, stores glycogen for energy storage, and participates in metabolism, its main and essential function is detoxification. Producing insulin is mainly attributed to the pancreas, not the liver.

4. Which gland is located superior to the kidney?

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.

5. What is true about caloric intake for the average person?

Correct answer: C

Rationale: Caloric intake for the average person typically declines with age due to factors such as changes in metabolism, muscle mass, and physical activity levels. As people age, their metabolism tends to slow down, and they may also experience a decrease in muscle mass and physical activity, leading to a reduced need for calories. Option A is incorrect because caloric intake generally decreases rather than increases with age. Option B is incorrect as it suggests a fluctuation in caloric intake that is not typically seen. Option D is incorrect as caloric needs usually change over a person's lifetime due to various factors.
