HESI A2 Anatomy and Physiology Quizlet

1. 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.

2. Which hormone is secreted by the pancreas to lower blood glucose levels?

Correct answer: A

Rationale: Insulin is secreted by the pancreas to lower blood glucose levels by facilitating the uptake of glucose into cells. It promotes the storage of glucose as glycogen in the liver and muscles, reducing blood sugar levels. Glucagon, on the other hand, works to raise blood glucose levels by stimulating the breakdown of glycogen into glucose and releasing it into the bloodstream. Somatostatin regulates the endocrine system and inhibits the release of insulin and glucagon. Cortisol is a hormone produced by the adrenal glands, not the pancreas, and it plays a role in stress response and metabolism, but it does not directly lower blood glucose levels.

3. What is the function of the large intestine in the digestive system?

Correct answer: B

Rationale: The large intestine's primary function is to absorb water from the remaining indigestible food matter that enters it from the small intestine. This absorption process helps in forming solid waste (feces) by compacting the material and preparing it for excretion. The large intestine does not secrete digestive enzymes, produce bile, or transport nutrients. Therefore, option B, 'To absorb water and form solid waste,' is the correct function of the large intestine in the digestive system.

4. What is the role of the spleen in the immune system?

Correct answer: A

Rationale: The spleen plays a crucial role in the immune system by filtering blood, specifically removing old or damaged red blood cells. It also stores lymphocytes, which are white blood cells that help fight infections. While the spleen does not produce white blood cells or antibodies, its main functions lie in blood filtration and storage of immune cells. Therefore, the correct answer is A. Choice B is incorrect because the spleen does not produce white blood cells. Choice C is incorrect as the spleen stores lymphocytes but does not primarily function to do so. Choice D is incorrect because the spleen does not produce antibodies.

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

Correct answer: A

Rationale: The primary function of the respiratory system is to absorb oxygen from the air into the bloodstream and expel carbon dioxide from the body. This process is essential for cellular respiration and the production of energy in the body. Option A, 'To absorb oxygen,' aligns with this crucial function, making it the correct choice. Choices B, C, and D are incorrect as they do not represent the primary function of the respiratory system. The respiratory system is not responsible for transporting nutrients (choice B), producing sound and speech (choice C), or regulating blood pressure (choice D).
