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. 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.

3. What substance makes up the pads that provide support between the vertebrae?

Correct answer: B

Rationale: Cartilage is the correct answer as it is the substance that makes up the pads between the vertebrae. Cartilage provides cushioning and support between the bones of the spine, allowing for flexibility and preventing friction between the vertebrae. Bone (choice A) is incorrect as it forms the structure of the vertebrae, not the intervertebral discs. Tendon (choice C) is incorrect as it connects muscle to bone and is not found between the vertebrae. Fat (choice D) is incorrect as it is not the substance that makes up the pads between the vertebrae.

4. How might vitamin D deficiency present?

Correct answer: D

Rationale: Vitamin D deficiency can present as crooked bones in children due to a condition called rickets. This is because vitamin D plays a crucial role in calcium absorption and bone health. Inadequate levels of vitamin D can lead to soft and weak bones, resulting in skeletal deformities such as bow legs or knock knees. Choices A, B, and C are incorrect as bleeding gums are more commonly associated with vitamin C deficiency (scurvy), swollen extremities could be a sign of various conditions like edema, and red patches are not typically a direct manifestation of vitamin D deficiency.

5. 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.
