HESI A2 Anatomy and Physiology Quizlet

1. Which part of the brain is responsible for regulating emotions and memory?

Correct answer: C

Rationale: The amygdala, located in the temporal lobe of the brain, is responsible for regulating emotions and memory, particularly those related to fear and pleasure. It plays a crucial role in processing emotional responses, forming emotional memories, and modulating emotional reactions. The cerebrum (Choice A) is responsible for higher brain functions such as thought and action. The cerebellum (Choice B) is mainly involved in coordination and balance. The brainstem (Choice D) controls basic life functions such as breathing and heart rate.

2. Which part of the brain is responsible for processing emotions?

Correct answer: B

Rationale: The correct answer is the amygdala. It is a small, almond-shaped structure located within the temporal lobe of the brain. The amygdala plays a crucial role in processing emotions such as fear, anger, pleasure, and other emotional responses. It is involved in the formation of emotional memories and helps regulate emotional responses to various stimuli. The frontal lobe is mainly responsible for higher cognitive functions such as decision-making and problem-solving, not processing emotions. The parietal lobe is involved in processing sensory information and spatial awareness, while the occipital lobe is primarily responsible for processing visual information.

3. What is the primary function of the respiratory system?

Correct answer: B

Rationale: The primary function of the respiratory system is to facilitate the exchange of gases. It transports oxygen from the air into the bloodstream, which is crucial for cellular respiration and providing energy to the cells. Additionally, it removes carbon dioxide, which is a waste product that needs to be eliminated. Choices A, C, and D are incorrect because while the respiratory system does remove carbon dioxide, its primary role is oxygen transport, not nutrient delivery, sound, or speech production.

4. Which hormone stimulates the production of red blood cells?

Correct answer: B

Rationale: Erythropoietin is the correct answer. It is the hormone responsible for stimulating the production of red blood cells. Erythropoietin is produced by the kidneys in response to low oxygen levels in the blood. This hormone promotes the generation of more red blood cells to increase the blood's oxygen-carrying capacity. Insulin (Choice A), Glucagon (Choice C), and Thyroxine (Choice D) do not stimulate the production of red blood cells. Insulin regulates blood sugar levels, Glucagon increases blood sugar levels, and Thyroxine regulates metabolism.

5. Which organ system is primarily responsible for maintaining temperature control?

Correct answer: D

Rationale: The integumentary system, which includes the skin, hair, and nails, is primarily responsible for maintaining temperature control in the body. The skin helps regulate body temperature through processes like sweating to cool down and shivering to generate heat. Additionally, blood vessels in the skin can dilate or constrict to control the amount of heat lost or retained by the body. This system plays a crucial role in maintaining homeostasis and keeping the body at a stable temperature. The skeletal system (Choice A) provides structural support and protection to the body but is not directly involved in temperature regulation. The digestive system (Choice B) is responsible for breaking down food and absorbing nutrients, not for regulating body temperature. The nervous system (Choice C) controls body functions through electrical impulses but is not the primary system responsible for temperature control.
