HESI A2 Anatomy and Physiology Quizlet

1. Which gland is located on top of the kidneys?

Correct answer: A

Rationale: The correct answer is the Adrenal gland. The adrenal glands are located on top of the kidneys. They produce hormones such as adrenaline and cortisol, which play essential roles in regulating metabolism, immune response, and stress in the body. The Thyroid gland, Pineal gland, and Pancreas are not located on top of the kidneys. The Thyroid gland is located in the neck, the Pineal gland in the brain, and the Pancreas behind the stomach.

2. Which is a posterior feature of the human leg?

Correct answer: D

Rationale: The correct answer is the Achilles tendon. The Achilles tendon is a strong tendon located at the back of the human leg, connecting the calf muscles to the heel bone. This positioning makes it a posterior feature, situated at the rear of the leg. The patella, also known as the kneecap, is positioned at the front of the leg, making it an anterior feature. The quadriceps sartorius are muscles located in the front of the thigh, not at the back of the leg. Additionally, the triceps brachii is a muscle found in the upper arm, not in the leg, making it an incorrect choice.

3. Which bones do the rotator cuff help to stabilize?

Correct answer: C

Rationale: The correct answer is C: Humerus and scapula. The rotator cuff is a group of muscles and tendons that help stabilize the shoulder joint. Specifically, the rotator cuff muscles help to stabilize the head of the humerus (the upper arm bone) within the shallow socket of the scapula (shoulder blade). This stabilizing action is crucial for maintaining shoulder joint function and preventing injuries. Choices A, B, and D are incorrect because the rotator cuff primarily stabilizes the humerus and scapula, not the radius, ulna, or clavicle.

4. Which system does the esophagus belong to?

Correct answer: B

Rationale: The esophagus is part of the digestive system. It is a muscular tube that connects the mouth to the stomach, allowing the passage of food and liquids from the mouth to the stomach for digestion. The esophagus plays a crucial role in the process of swallowing and digestion, which are essential functions of the digestive system. Choices A, C, and D are incorrect because the esophagus is not associated with the endocrine, respiratory, or nervous systems.

5. Which vitamin is essential for immune system function?

Correct answer: C

Rationale: Vitamin D is the correct answer. It is essential for immune system function as it helps regulate and support the immune response. Vitamin D plays a crucial role in calcium absorption, which is necessary for maintaining strong and healthy bones. Vitamin A is important for vision and skin health, not specifically immune function. Vitamin C is known for its antioxidant properties and its role in collagen production, not primarily for immune system function. Vitamin K is essential for blood clotting and bone health, but it is not directly related to immune system function.
