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 lymphatic system is to remove carbon dioxide from the body. Lymphatic vessels collect excess fluid and waste products from tissues and transport them back to the bloodstream for elimination. This process helps maintain fluid balance and removes metabolic waste. The other choices are incorrect because: A: Transporting oxygen to cells is primarily done by the circulatory system. C: Hormone production is mainly regulated by the endocrine system. D: Nutrient transport is primarily the role of the digestive system and the circulatory system.

Correct Answer: B

Rationale: The correct answer is B: To exchange gases. Lungs facilitate the exchange of oxygen and carbon dioxide between the bloodstream and the external environment during respiration. Oxygen is taken in and carbon dioxide is expelled. This process ensures the body receives oxygen for cellular respiration and removes waste carbon dioxide. Choice A (To filter blood) is incorrect as the lungs do not filter blood; that is the function of the kidneys and liver. Choice C (To produce energy) is incorrect as the lungs do not directly produce energy; energy production occurs at the cellular level. Choice D (To remove waste products) is partially correct, but the primary function of the lungs is gas exchange.

Correct Answer: A

Rationale: The correct answer is A: To filter waste from the blood. The kidneys act as filters, removing waste products and excess substances from the blood to form urine. This process helps maintain a balance of electrolytes and fluids in the body. Option B is incorrect because the kidneys do not produce urine from scratch; they filter blood to create urine. Option C is incorrect as the kidneys do play a role in regulating blood pressure, but it is not their primary function. Option D is also incorrect because while the kidneys do help maintain fluid balance, their primary function is waste filtration.
