HESI A2 Anatomy and Physiology Quizlet 2024

1. The lateral side of the right knee would be ___________.

Correct answer: C

Rationale: The lateral side of the right knee is the side that is farthest from the left knee when looking at the knee joint from the front. The term 'lateral' refers to the side of the body that is farther away from the midline or center of the body. In this case, the lateral side of the right knee is on the outer side of the knee joint, away from the other knee. Choice A is incorrect as the kneecap is located at the front of the knee. Choice B is incorrect as it describes the medial side, not the lateral side. Choice D is incorrect as it refers to the underside, which is not related to the lateral aspect of the knee.

2. Which of the following is a structure found in the upper respiratory tract?

Correct answer: B

Rationale: The pharynx is indeed a structure located in the upper respiratory tract. It acts as a common passageway for both air heading to the lungs and food traveling to the esophagus, making it a vital structure for breathing and swallowing functions. The larynx, trachea, and esophagus are also part of the respiratory and digestive systems but are not specifically located in the upper respiratory tract. The larynx is situated below the pharynx, while the trachea is found below the larynx, and the esophagus is part of the digestive system, not the respiratory tract.

3. What is the main function of the circulatory system?

Correct answer: A

Rationale: The main function of the circulatory system is to transport oxygen and nutrients to the body's cells while removing waste products. Oxygen and nutrients are carried by the blood to various tissues and organs, ensuring they receive essential elements for their proper function. Waste products are then removed from the cells and transported to the appropriate organs for elimination. This process ensures the overall well-being and functionality of the body. Choice B, removing waste products, is partially correct as one of the functions of the circulatory system is indeed to eliminate waste from the body. However, the primary function is to transport oxygen and nutrients. Choice C, regulating body temperature, is incorrect as temperature regulation is mainly controlled by the body's respiratory and integumentary systems. Choice D, protecting organs, is not a primary function of the circulatory system; protection is more closely associated with the immune system and the skeletal system.

4. What is the primary function of the liver?

Correct answer: A

Rationale: The primary function of the liver is to detoxify harmful substances in the blood. While the liver also produces bile, which aids in digestion, stores glycogen for energy storage, and participates in metabolism, its main and essential function is detoxification. Producing insulin is mainly attributed to the pancreas, not the liver.

5. To which system do the retinas belong?

Correct answer: B

Rationale: The retinas belong to the nervous system. The retina is a layer of tissue at the back of the eye responsible for detecting light and sending visual information to the brain through the optic nerve. This process is essential for vision, which is controlled by the nervous system. Choices A, C, and D are incorrect because the retinas have no association with the skeletal, lymphatic, or circulatory systems.
