ATI TEAS Science Questions Questions
Question 1 of 5
Which of the following is part of the cardiovascular system?
Correct Answer: A
Rationale: Blood vessels are indeed part of the cardiovascular system. They are crucial components that facilitate blood circulation by carrying blood throughout the body. The cardiovascular system consists of the heart, blood vessels (arteries, veins, and capillaries), and blood. Blood vessels play a vital role in delivering oxygen and nutrients to tissues and removing waste products. The brain, kidneys, and lungs are not part of the cardiovascular system; instead, they belong to other body systems. The brain is part of the nervous system, kidneys are part of the urinary system, and lungs are part of the respiratory system. Therefore, the correct answer is blood vessels (Choice A). Choices B, C, and D are incorrect as they are not components of the cardiovascular system but belong to different body systems.
Question 2 of 5
In which type of cell would you expect to find a high concentration of lysosomes?
Correct Answer: C
Rationale: The correct answer is C: Immune cells. Immune cells, such as macrophages, contain many lysosomes for breaking down pathogens. Lysosomes are organelles responsible for digestion and waste removal within the cell, and immune cells require a high concentration of lysosomes to aid in their defense mechanisms against pathogens. Choice A, Cardiac cells, is incorrect because lysosomes are not primarily abundant in cardiac cells. Choice B, Glandular cells, is incorrect as well since lysosomes are not specifically concentrated in glandular cells. Choice D, Neurons, is also incorrect because while lysosomes are present in neurons, they are not typically found in high concentrations compared to immune cells.
Question 3 of 5
Which of the following is an example of a pivot joint?
Correct Answer: B
Rationale: The correct answer is B: Neck. A pivot joint, as found in the neck, allows for rotational movement around a single axis. This type of joint is essential for movements like shaking your head 'no' or looking left and right. Choices A, C, and D are incorrect because the hip, shoulder, and elbow joints are examples of ball-and-socket joints, which allow for a wide range of motion in multiple directions, not just rotational movement around a single axis like a pivot joint.
Question 4 of 5
Which of the following arteries are not branches of the facial artery in the cervical portion?
Correct Answer: C
Rationale: The correct answer is C, the Superior labial artery. It is a branch of the facial artery in the facial portion, not in the cervical portion. The ascending palatine artery, glandular artery, and tonsillar artery are branches of the facial artery in the cervical portion. The ascending palatine artery supplies the palate, the glandular artery provides blood to the salivary glands, and the tonsillar artery is responsible for supplying blood to the tonsils. These arteries play a crucial role in the vascular supply of the head and neck region, aiding in various physiological functions.
Question 5 of 5
Which muscle is voluntary, striated, and found attached to bones?
Correct Answer: B
Rationale: The correct answer is B, Skeletal muscle. Skeletal muscle is both voluntary and striated, as well as attached to bones, allowing for movement. Smooth muscle, on the other hand, is involuntary and typically found in the walls of internal organs, controlling functions like digestion. Cardiac muscle is also striated, but it is involuntary and specifically found in the heart, responsible for cardiac contractions to pump blood. 'Epithelial muscle' is an incorrect term; epithelial tissue is a type of tissue that forms the linings of various body surfaces and structures, not a muscle type.
