TEAS 7 science practice questions

1. Which of the following is NOT a risk factor for developing atherosclerosis?

Correct answer: C

Rationale: Regular physical activity is not a risk factor for developing atherosclerosis; in fact, it is associated with a reduced risk. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. Regular physical activity plays a crucial role in improving cardiovascular health, reducing the risk of atherosclerosis, and maintaining overall well-being. Therefore, the correct answer is regular physical activity (choice C).

2. Which of the following is NOT a major function of the respiratory system in humans?

Correct answer: C

Rationale: Option C, 'It helps cushion the heart against jarring motions,' is NOT a major function of the respiratory system in humans. The primary functions of the respiratory system include gas exchange, regulation of blood pH, and vocalization. The respiratory system does not play a role in cushioning the heart; that function is primarily carried out by the pericardium and other protective structures around the heart. Choices A, B, and D are major functions of the respiratory system in humans. Choice A refers to the respiratory system's role in gas exchange, Choice B highlights its involvement in regulating blood pH, and Choice D points out its responsibility for vocalization.

3. Which deadly disease was eliminated through an intensive vaccination program?

Correct answer: B

Rationale: Smallpox was eradicated globally through an intensive vaccination program. The World Health Organization (WHO) led a successful global campaign to vaccinate people against smallpox, ultimately leading to its eradication in 1980. AIDS, diabetes type 1, and rheumatoid arthritis are serious conditions, but they were not eliminated through vaccination programs like smallpox. Therefore, the correct answer is B, Smallpox. AIDS is caused by the human immunodeficiency virus (HIV) and remains a significant global health issue. Diabetes type 1 is an autoimmune condition where the body attacks insulin-producing cells, leading to high blood sugar levels. Rheumatoid arthritis is an autoimmune condition that primarily affects the joints, causing inflammation and pain.

4. What is the scientific term for the windpipe, a tube that carries air from the larynx to the bronchi?

Correct answer: B

Rationale: The trachea is the correct scientific term for the windpipe, a tube that carries air from the larynx to the bronchi. It is an essential part of the respiratory system, enabling the passage of air to and from the lungs. The pharynx is the region behind the mouth and nasal cavity, acting as a passageway for air and food. The epiglottis is a cartilage flap that shields the trachea during swallowing to prevent food from entering the airway. Bronchioles are smaller airways that branch off from the bronchi within the lungs, further dividing and distributing air within the lungs.

5. What is the function of the adrenal glands?

Correct answer: D

Rationale: The correct answer is D: To regulate blood glucose. The adrenal glands play a crucial role in regulating blood glucose levels and the body's response to stress. Choice A, 'To regulate metabolism,' is incorrect as the primary role of the adrenal glands is not directly related to metabolism regulation. Choice B, 'To produce bile,' is incorrect because bile is produced by the liver, not the adrenal glands. Choice C, 'To produce red blood cells,' is also incorrect as the production of red blood cells primarily occurs in the bone marrow, not the adrenal glands.
