Review ATI Anatomy and Physiology Online Practice related questions and content

The anatomy of a body part is closely related to its physiology.

  • A. True
  • B. False
  • C. Not Sure
  • D. None of the above
Correct Answer: A

Rationale: The statement is true. Anatomy and physiology are interconnected fields. Anatomy focuses on the structure of body parts, while physiology deals with the functions of those parts. Understanding the structure (anatomy) of a body part is crucial in comprehending how it functions (physiology). This interrelation is essential for healthcare professionals to diagnose and treat medical conditions effectively. Choice B is incorrect because anatomy and physiology are indeed closely related. Choice C is incorrect as well because the relationship between anatomy and physiology is a fundamental concept in the study of the human body. Choice D is incorrect as the statement is true.

What is assimilation?

  • A. changing absorbed substances into different chemical forms
  • B. breaking down foods into nutrients that the body can absorb
  • C. eliminating waste from the body
  • D. an increase in body size without a change in overall shape
Correct Answer: A

Rationale: Assimilation is the process of changing absorbed substances into different chemical forms. It occurs after nutrients from food are absorbed into the bloodstream and used by the body. Choice B, breaking down foods into nutrients that the body can absorb, refers to the process of digestion rather than assimilation. Choice C, eliminating waste from the body, describes the process of excretion. Choice D, an increase in body size without a change in overall shape, does not accurately define assimilation.

The anatomical term that indicates a structure close to the surface is

  • A. anterior
  • B. proximal
  • C. superficial
  • D. superior
Correct Answer: C

Rationale: The correct answer is 'superficial.' In anatomy, the term 'superficial' refers to a structure that is close to the surface of the body. Choice A, 'anterior,' refers to the front of the body, not specifically to depth. Choice B, 'proximal,' refers to a structure that is closer to the point of attachment or trunk of the body. Choice D, 'superior,' indicates a structure that is above or higher in position.

Does the digestive system filter wastes from the blood?

  • A. TRUE
  • B. FALSE
  • C. Not Sure
  • D. None of the above
Correct Answer: B

Rationale: The correct answer is False. The digestive system is responsible for breaking down food and absorbing nutrients, not filtering wastes from the blood. The excretory system, particularly the kidneys, filters wastes from the blood to form urine. Choices A, C, and D are incorrect because the digestive system's primary function is not waste filtration but rather digestion and absorption of nutrients.

The ability of an organism to sense and react to changes in its body illustrates

  • A. circulation.
  • B. respiration.
  • C. responsiveness.
  • D. absorption
Correct Answer: C.

Rationale: The correct answer is 'responsiveness.' Responsiveness refers to the ability of an organism to detect and respond to stimuli in its environment. In this context, it specifically relates to an organism's ability to sense and react to changes within its body. Choices A, B, and D are incorrect. Circulation refers to the movement of fluids within an organism, respiration is the process of exchanging gases, and absorption is the uptake of substances by cells or tissues.

When does cell death first occur?

  • A. At age 60.
  • B. At age 50.
  • C. At puberty.
  • D. In the fetus.
Correct Answer: D

Rationale: Cell death, also known as apoptosis, first occurs during fetal development when specific cells are programmed to die. This process is essential for shaping and organizing tissues and organs. Choices A, B, and C are incorrect because cell death begins much earlier, during fetal development, rather than later in life or at puberty. Understanding the timing of cell death in different stages of life is crucial in developmental biology.
