Practice Science TEAS Test Questions
Question 1 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 2 of 5
Which of the following systems is responsible for transporting blood throughout the body?
Correct Answer: B
Rationale: The correct answer is B: Circulatory system. The circulatory system consists of the heart, blood vessels, and blood, responsible for transporting oxygen, nutrients, hormones, and waste products throughout the body. The respiratory system (A) is responsible for gas exchange, the nervous system (C) transmits signals, and the digestive system (D) processes food. The circulatory system is specifically designed for the transportation of blood, making it the correct choice.
Question 3 of 5
What is the primary function of the kidneys?
Correct Answer: B
Rationale: The correct answer is B: To filter blood and produce urine. The kidneys play a crucial role in filtering waste products and excess substances from the blood to form urine, which helps maintain the body's balance of fluids and electrolytes. This process is essential for regulating blood pressure, producing hormones, and maintaining overall bodily function. Choices A, C, and D are incorrect because the kidneys are not involved in digesting food, absorbing nutrients, or transporting oxygen.
Question 4 of 5
Water is considered a universal solvent due to its ____.
Correct Answer: B
Rationale: The correct answer is B: Adhesion. Water is considered a universal solvent because of its strong ability to adhere to other substances and dissolve a wide range of solutes. This property is essential for water to dissolve various molecules and ions, making it an effective solvent in nature. Cohesion (A) refers to water molecules sticking to each other, not to other substances. Molarity (C) is a measure of concentration, not a property of water as a solvent. Dilution (D) refers to the process of reducing the concentration of a solute in a solution, not the reason why water is a universal solvent.
Question 5 of 5
Which cavity contains all of the frontal cavities? Choose only ONE best answer.
Correct Answer: D
Rationale: The correct answer is D: Ventral. The frontal cavities are located in the anterior part of the body, which is synonymous with the ventral cavity. The ventral cavity contains multiple smaller cavities, including the thoracic and abdominopelvic cavities. The dorsal cavity is located at the back of the body and does not contain the frontal cavities. Therefore, the correct answer is the ventral cavity as it encompasses all of the frontal cavities within the body.
