HESI A2 Anatomy and Physiology Quizlet 2024 Questions

Question 1 of 5

A tissue examined under the microscope exhibits the following characteristics: cells found on the internal surface of the stomach, no extracellular matrix, cells tall and thin, no blood vessels in the tissue. What type of tissue is this?

Correct Answer: A

Rationale: The correct answer is A: Epithelial tissue. This is because the characteristics described match those of epithelial tissue, which lines surfaces and cavities in the body. The location on the internal surface of the stomach and the tall, thin cells indicate epithelial tissue. The absence of extracellular matrix and blood vessels also align with epithelial tissue characteristics. Connective tissue has extracellular matrix, cartilage is a specialized type of connective tissue, and nervous tissue contains nerve cells and supportive cells, which do not fit the given characteristics.

Question 2 of 5

The arteries are part of which system?

Correct Answer: D

Rationale: The correct answer is D: Cardiovascular system. Arteries are blood vessels that carry oxygen-rich blood away from the heart to the rest of the body. The cardiovascular system includes the heart, blood vessels, and blood. Arteries play a crucial role in this system by facilitating the circulation of blood. Explanation for incorrect choices: A: Nervous system - Arteries are not a part of the nervous system, which primarily consists of the brain, spinal cord, and nerves. B: Endocrine system - Arteries are not directly involved in the endocrine system, which is responsible for hormone production and regulation. C: Lymphatic system - Arteries are not part of the lymphatic system, which includes lymph nodes, lymphatic vessels, and lymph fluid.

Question 3 of 5

The spleen is part of which system?

Correct Answer: C

Rationale: The correct answer is C: lymphatic system. The spleen is a key organ in the lymphatic system, responsible for filtering blood, removing old or damaged red blood cells, and producing white blood cells. It plays a crucial role in the immune system. Incorrect choices: A: nervous system - The spleen is not part of the nervous system; it is not involved in transmitting nerve impulses. B: integumentary system - The spleen is not part of the integumentary system, which includes skin, hair, and nails. D: urinary system - The spleen is not part of the urinary system, which includes kidneys, ureters, bladder, and urethra.

Question 4 of 5

The lateral side of the right knee would be ___________.

Correct Answer: C

Rationale: The correct answer is C because the lateral side of the knee is the side farthest from the left knee. To determine this, visualize the body in anatomical position and observe that the right side is the outer side of the knee joint, making it the lateral side. The kneecap (A) is the patella, located at the front of the knee, not the lateral side. Being closest to the left knee (B) is inaccurate as the lateral side is actually on the opposite side. On the underside of the knee (D) refers to the posterior aspect, not the lateral side.

Question 5 of 5

What is true about caloric intake for the average person?

Correct Answer: C

Rationale: The correct answer is C: Caloric intake should decline with age. As individuals age, their metabolism slows down, leading to a decreased calorie requirement. Consuming more calories than needed can lead to weight gain and various health issues. Therefore, it is essential to adjust calorie intake based on age and activity level. Choices A, B, and D are incorrect because caloric intake typically decreases as individuals age due to changes in metabolism and activity levels.
