HESI A2 Version 1 Anatomy and Physiology Questions
Question 1 of 5
How many different types of tissues are there in the human body?
Correct Answer: A
Rationale: The human body is composed of four main types of tissues: epithelial, connective, muscle, and nervous tissue. Epithelial tissue covers body surfaces, connective tissue provides support and structure, muscle tissue allows movement, and nervous tissue coordinates body activities through electrical signals. Therefore, the correct answer is four.
Question 2 of 5
Which structure regulates the transport of substances in and out of a cell?
Correct Answer: C
Rationale:
Question 3 of 5
What are chemical messengers that control growth, differentiation, and the metabolism of specific target cells called?
Correct Answer: A
Rationale: Hormones are signaling molecules produced by glands that travel through the bloodstream to target cells, exerting control over processes like growth, differentiation, and metabolism. Neurons are nerve cells responsible for transmitting electrical impulses. Glands are structures that secrete substances like hormones. Second messengers are molecules involved in intracellular signal transduction pathways, amplifying and transmitting signals from the cell membrane to the nucleus.
Question 4 of 5
Which anatomical structure houses the terminal bronchioles?
Correct Answer: B

Question 5 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.
