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. Which structure in the kidney filters blood?

Correct answer: B

Rationale: The correct answer is the Glomerulus. The glomerulus is a network of tiny blood vessels located within the Bowman's capsule. It acts as the initial filtering component in the nephron, filtering blood and allowing waste products and excess substances to pass through to form urine. Choice A, Nephron, is incorrect as the nephron is the structural and functional unit of the kidney composed of several parts, including the glomerulus. Choice C, Bowman's capsule, is where the glomerulus is located, but it is not the structure responsible for filtering blood. Choice D, Loop of Henle, plays a role in reabsorption of water and electrolytes but is not the primary structure for blood filtration in the kidney.

3. Which hormone is produced by the adrenal cortex?

Correct answer: B

Rationale: The correct answer is B, Cortisol. Cortisol is the hormone produced by the adrenal cortex. It plays a crucial role in regulating metabolism, immune response, and managing stress. Insulin is produced by the pancreas, thyroxine by the thyroid gland, and glucagon by the pancreas. Therefore, choices A, C, and D are incorrect as they are not hormones produced by the adrenal cortex.

4. What is the average normal body temperature in degrees Celsius?

Correct answer: D

Rationale: The average normal body temperature in degrees Celsius is 37°C. This temperature is considered the standard measurement for the human body under normal conditions. It is essential to know this baseline temperature for monitoring health and detecting abnormalities such as fever. Choice A, 30°C, is too low for the average normal body temperature. Choice B, 32°C, is also below the standard normal body temperature. Choice C, 35°C, is closer but still lower than the average normal body temperature of 37°C.

5. Which fibrous connective tissue attaches muscles to bones?

Correct answer: A

Rationale: Tendons are fibrous connective tissues that attach muscles to bones, allowing the transmission of forces generated by muscles and facilitating movement at joints. Ligaments, on the other hand, connect bones to other bones, providing stability. Cartilage is a firm, flexible connective tissue found in joints and the respiratory tract. Fascia surrounds muscles, groups of muscles, blood vessels, and nerves, offering support and protection. Therefore, the correct answer is tendons as they specifically connect muscles to bones.
