Practice Science TEAS Test Questions
Question 1 of 5
Which of the following correctly orders the layers of the epidermis from most superficial to deepest?
Correct Answer: B
Rationale: The correct order of the layers of the epidermis from most superficial to deepest is: S. corneum, S. lucidum, S. granulosum, S. spinosum, S. basale (Choice B). This is because the outermost layer is the stratum corneum, followed by the stratum lucidum, then the stratum granulosum, stratum spinosum, and finally the stratum basale which is the deepest layer where new skin cells are produced. Choices A, C, and D do not follow this correct progression and therefore are incorrect.
Question 2 of 5
Which of the following is a function of the skeletal system?
Correct Answer: B
Rationale: The correct answer is B: To provide structural support. The skeletal system functions to support the body, protect internal organs, allow movement, and produce blood cells. Structural support is a primary function as bones form the framework of the body. Red blood cell production occurs in the bone marrow, not the skeletal system directly (A). Nutrient transport primarily involves the circulatory system, not the skeletal system (C). Fat storage is not a function of the skeletal system; it is mainly stored in adipose tissue (D). In summary, the skeletal system's main function is to provide structural support for the body.
Question 3 of 5
Which structure in the body is responsible for detecting light and converting it into signals for the brain?
Correct Answer: B
Rationale: The correct answer is B: Retina. The retina is a layer of light-sensitive cells located at the back of the eye that detects light and converts it into signals for the brain through the optic nerve. The iris (A) controls the amount of light entering the eye, the lens (C) helps to focus light onto the retina, and the pupil (D) regulates the amount of light entering the eye, but they do not convert light into signals for the brain like the retina does.
Question 4 of 5
Which of the following water-soluble vitamins is NOT synthesized in the large intestine?
Correct Answer: A
Rationale: The correct answer is A: B6. Vitamin B6, also known as pyridoxine, is not synthesized in the large intestine. It is primarily absorbed in the small intestine. Biotin, Pantothenic acid, and Vitamin K are all synthesized in the large intestine. Biotin and Pantothenic acid are produced by gut bacteria, while Vitamin K is synthesized by the intestinal flora. Therefore, the correct answer is A because B6 is not synthesized in the large intestine, unlike the other options.
Question 5 of 5
What is the role of the diaphragm in respiration?
Correct Answer: B
Rationale: The correct answer is B: To contract and expand the lungs. The diaphragm is a dome-shaped muscle that plays a crucial role in respiration by contracting and relaxing to create changes in lung volume, allowing air to flow in and out of the lungs. When the diaphragm contracts, it flattens, increasing the space in the chest cavity and causing inhalation. When it relaxes, it returns to its dome shape, decreasing the space in the chest cavity and causing exhalation. Incorrect choices: A: To regulate air pressure in the lungs - While the diaphragm indirectly affects air pressure by creating changes in lung volume, its primary role is in creating the necessary space for inhalation and exhalation. C: To store oxygen - The diaphragm is a muscle and does not store oxygen. Oxygen is primarily stored in the blood and tissues. D: To break down carbon dioxide - The diaphragm is not involved in breaking down carbon dioxide. Carbon dioxide is
