TEAS Practice Test Science Questions

Question 1 of 5

Which type of joint connects the bones of the skull?

Correct Answer: B

Rationale: The correct answer is B: Fibrous. Fibrous joints connect bones of the skull with fibrous tissue, providing stability and limited movement. Synovial joints (Choice A) have a joint cavity with synovial fluid for movement but aren't found in the skull. Cartilaginous joints (Choice C) connect bones with cartilage and allow slight movement, not commonly found in the skull. Ball-and-socket joints (Choice D) allow the widest range of motion and are not present in the skull. Therefore, the fibrous joint is the most suitable type for connecting the bones of the skull.

Question 2 of 5

Which of the following structures is responsible for gas exchange in the lungs?

Correct Answer: B

Rationale: The correct answer is B: Alveoli. Alveoli are tiny air sacs in the lungs where gas exchange occurs. Oxygen is taken in from the air and carbon dioxide is released into the air through the alveoli walls. The bronchi (A) are airways that carry air into the lungs but do not participate in gas exchange. The trachea (C) is the windpipe that connects the throat to the lungs and does not directly participate in gas exchange. The diaphragm (D) is a muscle that aids in breathing by contracting and relaxing to change the volume of the chest cavity but is not directly involved in gas exchange.

Question 3 of 5

What is the role of the large intestine in the digestive system?

Correct Answer: B

Rationale: The large intestine's main role is to absorb water and form feces. First, undigested material passes from the small intestine to the large intestine. Second, water is absorbed, making the stool more solid. Finally, the formed feces are stored until they are eliminated from the body. This process is crucial for maintaining proper hydration and eliminating waste. Choices A, C, and D are incorrect as they describe functions performed by other parts of the digestive system, such as the stomach and small intestine.

Question 4 of 5

Where does the electron transport chain occur in the cell?

Correct Answer: C

Rationale: The correct answer is C: Inner mitochondrial membrane. The electron transport chain occurs in the inner mitochondrial membrane because it is where the proteins and complexes involved in oxidative phosphorylation are located. This is where electrons are passed along the chain, leading to the production of ATP. The cytosol (choice A) is where glycolysis occurs, not the electron transport chain. The Golgi apparatus (choice B) is involved in protein processing and sorting, not energy production. The nucleus (choice D) houses the cell's genetic material and is not directly involved in the electron transport chain.

Question 5 of 5

Which part of the heart receives oxygenated blood from the lungs?

Correct Answer: A

Rationale: The correct answer is A: Left atrium. The left atrium receives oxygenated blood from the lungs via the pulmonary veins. This oxygenated blood is then pumped into the left ventricle and circulated to the rest of the body. The right atrium receives deoxygenated blood from the body via the vena cava. Choices B, C, and D are incorrect because the right atrium receives deoxygenated blood from the body, the left ventricle pumps oxygenated blood to the body, and the right ventricle pumps deoxygenated blood to the lungs for oxygenation, respectively.
