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. The spleen is part of which system?

Correct answer: C

Rationale: The correct answer is C: lymphatic system. The spleen is a vital organ in the lymphatic system, responsible for filtering blood, producing and storing white blood cells, and aiding the body in fighting infections. The lymphatic system is crucial for maintaining the body's immune defenses and fluid balance. Choices A, B, and D are incorrect because the spleen is not part of the nervous system, integumentary system, or urinary system.

3. Which hormone is responsible for regulating blood sugar levels?

Correct answer: A

Rationale: Insulin, produced by the pancreas, is the hormone responsible for regulating blood sugar levels. It works by facilitating the uptake of glucose into cells, helping to lower blood sugar levels. Glucagon, on the other hand, works to increase blood sugar levels by promoting the release of glucose from the liver. Thyroxine is a hormone produced by the thyroid gland that regulates metabolism. Melatonin, a hormone that helps regulate sleep-wake cycles, is not responsible for regulating blood sugar levels. Therefore, the correct answer is insulin.

4. Which part of the brain is responsible for processing sensory information?

Correct answer: B

Rationale: The parietal lobe of the brain is responsible for processing sensory information such as touch, temperature, and pain. It integrates sensory information from various parts of the body, allowing an individual to perceive and respond to different stimuli. Functions like spatial awareness and perception of the body's position in space are also associated with the parietal lobe. The frontal lobe is responsible for functions like decision-making and personality. The occipital lobe is primarily involved in visual processing, and the temporal lobe plays a role in memory and auditory processing.

5. What is the role of the pancreas in digestion?

Correct answer: A

Rationale: The correct answer is A: To secrete digestive enzymes. The pancreas is responsible for secreting digestive enzymes that aid in breaking down carbohydrates, fats, and proteins in the small intestine, facilitating the process of digestion. Choice B is incorrect because the pancreas does not store bile; that is primarily the function of the gallbladder. Choice C is incorrect as the absorption of nutrients mainly occurs in the small intestine, not the pancreas. Choice D is incorrect as the transport of glucose is primarily regulated by insulin produced in the pancreas, but this is not the main role of the pancreas in digestion.
