ATI TEAS Practice Test Science Questions

Question 1 of 5

From an anterior view, which of the following vessels carries blood away from the heart?

Correct Answer: D

Rationale: The correct answer is D, 'All of the above.' When viewed from an anterior perspective, the left common carotid artery, pulmonary trunk, and subclavian arteries all carry blood away from the heart. The left common carotid artery supplies oxygenated blood to the head and neck, the pulmonary trunk carries deoxygenated blood to the lungs for oxygenation, and the subclavian arteries transport blood to the upper extremities. Therefore, all the vessels listed in the choices are correct as they function to carry blood away from the heart when viewed anteriorly.

Question 2 of 5

What type of joint is found at the shoulder and hip, allowing for a wide range of motion?

Correct Answer: B

Rationale: The correct answer is B: Ball-and-socket joint. A ball-and-socket joint, like the ones found at the shoulder and hip, allows for a wide range of motion. These joints provide multidirectional movement due to the rounded end of one bone fitting into the cup-like socket of another bone, enabling flexion, extension, abduction, adduction, and rotation. Choice A, Hinge joint, is incorrect because hinge joints allow movement in one plane, like a door hinge, and do not provide the wide range of motion seen at the shoulder and hip. Choice C, Pivot joint, is incorrect because pivot joints allow rotation around a single axis, such as the neck, and do not provide the same range of motion as ball-and-socket joints. Choice D, Saddle joint, is incorrect as saddle joints allow movement in multiple directions but are not as versatile or allow as wide a range of motion as ball-and-socket joints.

Question 3 of 5

What is the function of the pleurae?

Correct Answer: A

Rationale: The pleurae play a crucial role in compartmentalizing and lubricating the lungs. The pleura is a double-layered membrane that surrounds the lungs and lines the chest cavity. This double-layered structure reduces friction between the lungs and the chest wall during breathing movements, allowing smooth expansion and contraction of the lungs. Options B, C, and D are incorrect. Option B, 'To facilitate the flow of air,' is incorrect because while the pleurae are involved in the respiratory process, their primary function is not to directly facilitate the flow of air. Option C, 'To produce mucus,' is incorrect as the production of mucus is not a primary function of the pleurae. Option D, 'To serve as the passageway for air,' is incorrect as the passageway for air refers to the air passages like the trachea and bronchi, not the pleurae. Therefore, option A is correct as it accurately describes the function of the pleurae.

Question 4 of 5

Where does glycolysis occur within the cell?

Correct Answer: A

Rationale: Glycolysis occurs in the cytosol, the liquid component of the cytoplasm, not in the nucleus, mitochondria, or endoplasmic reticulum. It is the initial step in cellular respiration and involves the breakdown of glucose into pyruvic acid. The process takes place in the cytosol as it does not require membrane-bound organelles like the mitochondria or endoplasmic reticulum for its completion.

Question 5 of 5

Which organelle in the cell is responsible for producing energy in the form of ATP?

Correct Answer: B

Rationale: The correct answer is B: Mitochondria. Mitochondria are known as the powerhouses of the cell and are responsible for producing energy in the form of ATP through cellular respiration. ATP is the primary energy currency of the cell, powering various cellular activities. The nucleus (choice A) is responsible for housing the cell's genetic material but is not involved in ATP production. Ribosomes (choice C) are involved in protein synthesis, not energy production. The Golgi apparatus (choice D) is responsible for modifying, sorting, and packaging proteins for secretion, not for ATP production.
