ATI TEAS 7 Science Questions

Question 1 of 5

Which of the following structures is responsible for transmitting electrical impulses in the nervous system?

Correct Answer: A

Rationale: The correct answer is A: Neuron. Neurons are specialized cells that transmit electrical impulses in the nervous system. They consist of a cell body, dendrites to receive signals, an axon to transmit signals, and synaptic terminals to communicate with other neurons. The axon is the long fiber that carries the electrical impulses away from the cell body. Myelin is a fatty substance that insulates and speeds up signal transmission along the axon. Dendrites receive signals from other neurons and transmit them towards the cell body. Therefore, the neuron is the fundamental structure responsible for transmitting electrical impulses, making it the correct answer.

Question 2 of 5

What is the primary function of the lymphatic system?

Correct Answer: C

Rationale: The primary function of the lymphatic system is to fight infection and remove excess fluid. Lymph nodes contain white blood cells that help fight pathogens. Lymphatic vessels collect excess fluid from tissues and transport it back to the bloodstream, aiding in immune response. Other choices are incorrect because A: Oxygen transport is primarily done by the circulatory system, B: Blood filtration is mainly carried out by the kidneys, and D: Hormone transport is primarily through the circulatory system.

Question 3 of 5

What is the maximum volume of air that the lungs can hold after a full forced inhalation?

Correct Answer: C

Rationale: The correct answer is C: Total lung capacity. Total lung capacity is the maximum volume of air the lungs can hold after a full forced inhalation. It includes all the volumes within the lungs, such as tidal volume, inspiratory reserve volume, expiratory reserve volume, and residual volume. It is the sum of vital capacity and residual volume. Inspiratory capacity (A) is the maximum volume of air that can be inhaled after a normal exhalation. Tidal volume (B) is the volume of air inspired or expired during normal breathing. Vital capacity (D) is the maximum volume of air that can be exhaled after a maximum inhalation, not the total volume the lungs can hold.

Question 4 of 5

What are the finger-like projections that increase the surface area for absorption in the small intestine called?

Correct Answer: C

Rationale: Failed to generate a rationale after 5 retries.

Question 5 of 5

What are apocrine and eccrine?

Correct Answer: D

Rationale: Apocrine and eccrine are types of sweat glands in the human body. Apocrine glands are found in areas like the armpits and groin, while eccrine glands are distributed throughout the skin. These glands play a crucial role in regulating body temperature through sweat production. Therefore, the correct answer is D: Sweat glands. A: Blood vessel - Incorrect. Apocrine and eccrine are not blood vessels. B: Cell types - Incorrect. Apocrine and eccrine are not cell types. C: Hormones - Incorrect. Apocrine and eccrine are not hormones.
