ATI TEAS 7
TEAS Test 7 science
1. Urine, the liquid waste product of the body, travels from the kidneys to the bladder through tubes called:
- A. Ureters
- B. Urethra
- C. Nephrons
- D. Renal pelvis
Correct answer: A
Rationale: The correct answer is 'Ureters.' Ureters are tubes that connect each kidney to the bladder. They transport urine from the kidneys to the bladder for storage before excretion. The urethra, which is not the correct answer, is responsible for carrying urine from the bladder out of the body. Nephrons, another incorrect choice, are microscopic units within the kidneys that filter blood and produce urine. The renal pelvis, also an incorrect choice, is a structure in the kidney where urine collects before moving into the ureters for further passage to the bladder.
2. How does an increase in surface area affect the force of friction between two surfaces?
- A. Increases friction
- B. Decreases friction
- C. Has no effect on friction
- D. Causes unpredictable changes in friction
Correct answer: A
Rationale: An increase in surface area typically increases the force of friction between two surfaces. This is because with a larger surface area in contact, there are more points of contact between the surfaces, leading to a greater frictional force resisting motion. As a result, the correct answer is that an increase in surface area increases the force of friction between two surfaces. Choice B is incorrect because a greater surface area increases the frictional force. Choice C is incorrect because an increase in surface area results in more contact points and greater friction. Choice D is incorrect as the relationship between surface area and friction is predictable - an increase in surface area generally leads to an increase in frictional force.
3. Which organ is primarily responsible for detoxification in the body?
- A. Kidney
- B. Liver
- C. Lung
- D. Heart
Correct answer: B
Rationale: The liver is the primary organ responsible for detoxifying chemicals and metabolizing drugs in the body. It plays a crucial role in breaking down toxins, filtering blood, and producing bile, making it essential for overall detoxification processes. The kidney primarily filters waste and excess substances from the blood to form urine. Lungs are responsible for gas exchange, not detoxification. The heart is responsible for pumping blood and does not play a direct role in detoxification processes.
4. Which of the following is NOT a state of matter?
- A. Solid
- B. Liquid
- C. Gas
- D. Superfluid
Correct answer: D
Rationale: The correct answer is 'Superfluid.' Superfluid is not considered a traditional state of matter. It is a unique phase of matter that displays zero viscosity and flows without losing kinetic energy. Solids, liquids, and gases are the three classical states of matter distinguished by their physical properties and structures. Therefore, choices A, B, and C are considered states of matter, while choice D, superfluid, is not.
5. What is the name of the master gland that regulates the function of many other endocrine glands?
- A. Thyroid gland
- B. Pituitary gland
- C. Hypothalamus
- D. Adrenal gland
Correct answer: B
Rationale: The pituitary gland is commonly referred to as the master gland because it controls the functions of numerous other endocrine glands in the body. It secretes various hormones that are essential for regulating processes like growth, metabolism, reproduction, and stress response. The thyroid gland (Choice A) primarily regulates metabolism and does not oversee other endocrine glands. The hypothalamus (Choice C) plays a role in regulating the pituitary gland but is not the master gland. The adrenal gland (Choice D) produces hormones related to stress response but is not considered the master gland that regulates other endocrine glands.
