HESI A2 Version 1 Anatomy and Physiology Questions
Question 1 of 5
Which type of cholesterol is considered the best for health?
Correct Answer: B
Rationale: High-density lipoprotein (HDL) is considered the best type of cholesterol for health. HDL helps remove excess cholesterol from the bloodstream, reducing the risk of heart disease. Conversely, low-density lipoprotein (LDL) is often referred to as 'bad' cholesterol as it can lead to plaque buildup in arteries. Very low-density lipoprotein (VLDL) and very high-density lipoprotein (VHDL) are not commonly used terms in cholesterol classification.
Question 2 of 5
What substance makes up the pads that provide support between the vertebrae?
Correct Answer: B
Rationale: Cartilage is the substance that makes up the pads providing support between the vertebrae. These pads, known as intervertebral discs, consist of tough outer layers of fibrous cartilage and a gel-like inner core. Cartilage plays a crucial role in cushioning the vertebrae, absorbing shock, and maintaining flexibility in the spine.
Question 3 of 5
What is the name of the outermost layer of the skin?
Correct Answer: B
Rationale: The correct answer is B, 'epidermis.' The epidermis is the outermost layer of the skin, providing a protective barrier against environmental factors and regulating water loss. The dermis is located beneath the epidermis and contains important structures like blood vessels and glands. Subcutaneous tissue, also known as the hypodermis, is located below the dermis and serves functions such as insulation and energy storage.

Question 5 of 5
Which of the following are tropic hormones? (Select one that doesn't apply.)
Correct Answer: C
Rationale: Tropic hormones are hormones that stimulate other endocrine glands to release their hormones. Antidiuretic hormone (C) is not a tropic hormone; it acts on the kidneys to regulate water balance. Somatotropin (A), follicle-stimulating hormone (B), and thyroid-stimulating hormone (D) are all tropic hormones that stimulate the release of hormones from other glands.
