Quizlet HESI A2 Anatomy and Physiology

Correct Answer: B

Rationale: The correct answer is B: To produce hormones. Adrenal glands are responsible for producing important hormones such as cortisol, adrenaline, and aldosterone. These hormones play crucial roles in regulating metabolism, immune response, and stress levels. Choice A is incorrect because blood sugar regulation is primarily controlled by the pancreas. Choice C is incorrect as the production of red blood cells occurs in the bone marrow. Choice D is incorrect as the filtering of blood is mainly carried out by the kidneys.

Choice C is incorrect as the production of red blood cells occurs in the bone marrow. Choice D is incorrect as the filtering of blood is mainly carried out by the kidneys.

Correct Answer: B

Rationale: The primary function of the circulatory system is to transport oxygen and nutrients throughout the body. The heart pumps blood containing oxygen and nutrients to all cells and tissues. This process supports cellular functions and provides energy. Hormone production (A) is mainly regulated by the endocrine system. Fighting infections (C) is primarily the role of the immune system. Regulating body temperature (D) is primarily controlled by the thermoregulatory system. Overall, the circulatory system's main role is the transport of oxygen and nutrients, making choice B the correct answer.

Correct Answer: B

Rationale: The primary function of the digestive system is to break down food through mechanical and chemical processes, and absorb nutrients for the body's energy and growth. This process involves enzymes, acids, and various organs like the stomach and intestines. Option A is incorrect as oxygen transportation is primarily done by the respiratory system. Option C is incorrect as hormone production is mainly regulated by the endocrine system. Option D is incorrect as blood transportation is the role of the circulatory system.

Correct Answer: C

Rationale: The correct answer is C: To absorb oxygen and remove carbon dioxide. The main function of the respiratory system is to facilitate the exchange of gases, where oxygen is taken in and carbon dioxide is expelled. This process is essential for cellular respiration and energy production in the body. Choices A and D are incorrect because nutrient transportation and energy production are primarily carried out by the circulatory and digestive systems. Choice B is incorrect as regulating body temperature is mainly controlled by the integumentary system and thermoregulation mechanisms.
