Question 1

Which of the following best describes the relationship between anatomy and physiology?

Accepted Answer

Anatomy studies the structures of the body, while physiology studies the functions of those structures; both are interrelated and affect each other.

Question 2

Which organizational level is considered the smallest unit of life in the human body?

Accepted Answer

Cell

Question 3

A researcher is studying the structure of cardiac muscle tissue under a microscope. Which branch of anatomy is she practicing?

Accepted Answer

Microscopic anatomy

Question 4

Which of the following correctly lists the levels of organization in the human body from simplest to most complex?

Accepted Answer

Chemical, cell, tissue, organ, organ system, organism

Question 5

Which organ system is responsible for transporting nutrients, gases, and wastes throughout the body?

Accepted Answer

Cardiovascular system

Question 6

A patient is lying face up on an examination table. What is the anatomical term for this position?

Accepted Answer

Supine

Question 7

Which anatomical plane divides the body into right and left portions?

Accepted Answer

Sagittal plane

Question 8

Which of the following best describes negative feedback in homeostatic regulation?

Accepted Answer

The control center's response opposes the initial stimulus, maintaining a variable within a normal range.

Question 9

During childbirth, uterine contractions become stronger and more frequent due to the release of oxytocin. This is an example of:

Accepted Answer

Positive feedback

Question 10

Which membrane directly covers the lungs?

Accepted Answer

Visceral pleura

Question 11

A surgeon needs to access the heart for a procedure. Which cavity and membrane will she encounter first?

Accepted Answer

Pericardial cavity; parietal pericardium

Question 12

Which of the following is NOT a function of serous membranes?

Accepted Answer

Producing hormones for homeostasis

Question 13

If a patient has damage to the mediastinum, which of the following structures could be affected?

Accepted Answer

Heart

Question 14

Which anatomical term refers to a structure that is farther from the point of attachment to the body?

Accepted Answer

Distal

Question 15

A cross-section of the body that separates the superior and inferior portions is made along which plane?

Accepted Answer

Transverse plane

Question 16

Which abdominal region is located directly below the umbilical region?

Accepted Answer

Hypogastric (pubic) region

Question 17

Which of the following best explains why failure to maintain homeostasis can result in disease or death?

Accepted Answer

Homeostasis maintains a dynamic equilibrium; disruption can cause physiological systems to fail, leading to disease or death.

Question 18

Which of the following is an example of extrinsic regulation in homeostasis?

Accepted Answer

The nervous system increases heart rate during exercise.

Question 19

Which organ system includes the heart, blood vessels, and blood?

Accepted Answer

Cardiovascular system
