HESI A2 Anatomy and Physiology Quizlet 2024 Questions
Question 1 of 5
Which organ system is primarily responsible for storing minerals?
Correct Answer: A
Rationale: The correct answer is A: The skeletal system. The skeletal system stores minerals, primarily calcium and phosphorus, in the bones. These minerals help maintain bone density and strength. The endocrine system (B) regulates hormone production, the lymphatic system (C) helps with immune function, and the cardiovascular system (D) transports nutrients and oxygen. However, the primary function of storing minerals is carried out by the skeletal system due to its composition of bones.
Question 2 of 5
What is true about caloric intake for the average person?
Correct Answer: C
Rationale: The correct answer is C: Caloric intake should decline with age. As individuals age, their metabolism slows down, leading to a decreased calorie requirement. Consuming more calories than needed can lead to weight gain and various health issues. Therefore, it is essential to adjust calorie intake based on age and activity level. Choices A, B, and D are incorrect because caloric intake typically decreases as individuals age due to changes in metabolism and activity levels.
Question 3 of 5
Which organ system is primarily responsible for storing minerals?
Correct Answer: A
Rationale: The correct answer is A: The skeletal system. The skeletal system stores minerals, primarily calcium and phosphorus, in the bones. These minerals help maintain bone density and strength. The endocrine system (B) regulates hormone production, the lymphatic system (C) helps with immune function, and the cardiovascular system (D) transports nutrients and oxygen. However, the primary function of storing minerals is carried out by the skeletal system due to its composition of bones.
Question 4 of 5
The corpus callosum facilitates communication between which brain structures?
Correct Answer: A
Rationale: The corpus callosum connects the left and right hemispheres of the brain, facilitating communication between them. This allows for integration of sensory information and coordination of cognitive functions. Choice A is correct as it accurately describes the function of the corpus callosum. Choices B, C, and D are incorrect because they do not involve the specific brain structures connected by the corpus callosum. Option B refers to different body systems, Option C involves the brain and spinal cord, and Option D mentions specific brain regions not directly connected by the corpus callosum.
Question 5 of 5
The orthopedic surgeon informs you that you have broken the middle region of the humerus. What area is he describing?
Correct Answer: D
Rationale: The correct answer is D: Diaphysis. The diaphysis refers to the middle region of a long bone, such as the humerus. In this case, the orthopedic surgeon is describing the part of the bone where the break has occurred. The other choices are incorrect because: A: Epiphysis is the end of a long bone, not the middle region. B: Articular cartilage is the smooth, slippery surface covering the ends of bones in a joint, not the middle region. C: Perichondrium is the connective tissue surrounding cartilage, not the middle region.
