Mometrix TEAS 7 science practice test
1. Which of the following is NOT a function of the nervous system?
- A. Detecting touch
- B. Regulating body temperature
- C. Producing insulin
- D. Controlling muscle movement
Correct answer: C
Rationale: The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Producing insulin (option C) is a function of the endocrine system, which produces hormones like insulin to regulate metabolism and glucose levels. Therefore, option C is the correct answer as it is not a function of the nervous system.
2. What is the muscular sac that stores urine until it is released from the body known as?
- A. Urethra
- B. Bladder
- C. Ureter
- D. Nephron
Correct answer: B
Rationale: The bladder is the muscular sac that stores urine until it is released from the body. It acts as a reservoir for urine until it is eliminated through the urethra. The urethra is the tube responsible for carrying urine from the bladder to the outside. The ureter transports urine from the kidneys to the bladder. The nephron is the structural and functional unit of the kidney involved in the filtration of blood and urine production. Therefore, the correct answer is the bladder, as it specifically fulfills the function of storing urine before its elimination.
3. What is the role of the large intestine in the digestive system?
- A. To break down proteins
- B. To absorb water and form feces
- C. To digest fats
- D. To neutralize stomach acid
Correct answer: B
Rationale: The correct answer is B. The large intestine plays a crucial role in absorbing water from indigestible food matter and forming feces for elimination. Choice A is incorrect because the breakdown of proteins primarily occurs in the stomach and small intestine. Choice C is incorrect as the digestion of fats primarily occurs in the small intestine. Choice D is incorrect as neutralizing stomach acid is mainly the function of the stomach lining and not the large intestine.
4. What are the three types of muscle tissues?
- A. Cardiac, smooth, epithelial
- B. Skeletal, cardiac, smooth
- C. Cardiac, smooth, connective
- D. Skeletal, epithelial, connective
Correct answer: B
Rationale: The correct answer is B: Skeletal, cardiac, smooth. Skeletal muscle tissue is responsible for voluntary movement, cardiac muscle tissue is found in the heart and is responsible for involuntary heart contractions, and smooth muscle tissue is located in organs and is responsible for involuntary movements. Therefore, the three types of muscle tissues are skeletal, cardiac, and smooth. Choices A, C, and D are incorrect because they include types of tissues that are not classified as muscle tissues. Epithelial and connective tissues are different types of tissues that serve other functions in the body, not related to muscle contractions.
5. What is the main function of the lungs?
- A. To transport oxygen and nutrients throughout the body
- B. To coordinate movement and sensory information
- C. To filter waste products from the blood
- D. To exchange oxygen and carbon dioxide between the body and the environment
Correct answer: D
Rationale: The main function of the lungs is to exchange oxygen and carbon dioxide between the body and the environment. This process occurs through the alveoli in the lungs where oxygen from inhaled air enters the bloodstream, and carbon dioxide is removed from the bloodstream and exhaled. Option A is incorrect as the transportation of oxygen and nutrients throughout the body is primarily carried out by the circulatory system, not the lungs. Option B is incorrect as coordinating movement and sensory information is a function of the nervous system, not the lungs. Option C is incorrect as filtering waste products from the blood is primarily the role of the kidneys, not the lungs. Therefore, the correct answer is D.
