ATI TEAS Science Test Questions

Question 1 of 5

Which statement correctly matches the valve with its function in the heart?

Correct Answer: A

Rationale: The correct answer is A. The aortic valve allows oxygenated blood to flow from the left ventricle to the rest of the body. When the left ventricle contracts, the aortic valve opens to allow blood to be pumped into the aorta, the body's main artery that carries oxygen-rich blood to various parts of the body. Choices B, C, and D are incorrect because they do not match the described functions of the mitral, pulmonic, and tricuspid valves, respectively. The mitral valve controls the flow of blood between the left atrium and left ventricle, the pulmonic valve regulates the flow of blood from the right ventricle to the pulmonary artery, and the tricuspid valve manages the blood flow between the right atrium and right ventricle.

Question 2 of 5

Long bones are one of the five major types of bones in the human body. All of the following bones are long bones, EXCEPT

Correct Answer: D

Rationale: Long bones are one of the five major types of bones in the human body, characterized by their elongated shape. Thighs, forearms, and ankles are examples of long bones as they are longer than they are wide and have a tubular structure, aiding in support and movement. Fingers, however, are categorized as short bones due to their small size and shape. Short bones like fingers are essential for providing dexterity and precise movements rather than supporting weight or acting as levers for movement. Therefore, the correct answer is D, Fingers, as they are not classified as long bones.

Question 3 of 5

Which of the following anatomical terms is not part of the knee?

Correct Answer: C

Rationale: The lateral malleolus is a bony prominence on the lateral side of the ankle and is not part of the knee anatomy. The other options - medial collateral ligament, patella, and lateral meniscus - are all structures within the knee joint. The medial collateral ligament is located on the inner side of the knee, the patella is the kneecap, and the lateral meniscus is a cartilage structure within the knee joint. Therefore, the correct answer is C, lateral malleolus.

Question 4 of 5

Which of the following items is NOT a primary function of a healthy immune system?

Correct Answer: D

Rationale: The correct answer is D. The primary functions of a healthy immune system do not involve creating infections. A healthy immune system helps the body avoid infections by providing defense mechanisms, detects infections by recognizing harmful pathogens, and eliminates infections by attacking and clearing out pathogens. Creating infections goes against the protective role of the immune system and is not a function it performs. Therefore, choices A, B, and C are correct functions of a healthy immune system, while choice D is incorrect.

Question 5 of 5

What is the process called in which a substance changes from a gas to a liquid?

Correct Answer: A

Rationale: Condensation is indeed the correct answer. It is the process by which a substance changes from a gas to a liquid. This occurs when the temperature of a gas decreases enough for its particles to lose energy and come together to form a liquid. On the other hand, evaporation is the process of a liquid changing to a gas. Sublimation is the direct transition of a substance from a solid to a gas without passing through the liquid phase. Vaporization, on the other hand, is the general term for the process of a liquid changing to a gas, which includes both evaporation and boiling.
