Chapter 1: The Human Body: An Orientation

Chapter Practice Test
This activity contains 20 questions.

Which of the following best defines physiology?
The study of all chemical reactions that occur within body cells. The study of how the body parts work and carry out their life-sustaining activities. The study of tissues.
The study of the structure of body parts and their relationships to one another.

Which of the following best describes macroscopic anatomy?
The study of structural changes caused by disease.
The study of structures too small to be seen with the naked eye. The study of large body structures visible to the naked eye, such as the heart, lungs, and kidneys. The study of structural changes that occur in the body throughout one's lifespan.

Embryology is a subdivision of anatomy that deals with developmental changes that occur before birth. True/ False

Blood flows in one direction through the heart because the heart has valves that prevent backflow. This phenomenon exemplifies: the principle of complementarity of structure and function. the principle of microscopic anatomy.

the principle of structural organization.
the principles of cardiovascular physiology.

Which of the following represents the sum total of all structural levels working together to keep us alive? Molecular level
Chemical level
Organismal level
Cellular level
The human body as a whole is enclosed and protected by the integumentary system. This is an example of a necessary life function. Select the correct function from the list below. Metabolism
Responsiveness
Maintaining Boundaries
Homeostasis

Metabolism includes breaking down substances into their simpler building blocks, synthesizing complex cellular structures from simpler substances, and using nutrients and oxygen to produce ATP. True/ False

Which of the following processes require a receptor, a control center, and an effector? Homeostatic control
Maintaining Boundaries
Movement
Responsiveness

Which of the following is an example of a positive feedback mechanism? The control of blood sugar by insulin
The regulation of body temperature
The control of blood volume by ADH
Blood clotting

Which of the following is true of positive feedback mechanisms? The result or response enhances the original stimulus, and the response is accelerated. The output shuts off the original stimulus or reduces its intensity. Their purpose is to prevent sudden severe changes within the body. The variable changes in a direction opposite to that of the initial change.

The knee is distal to the thigh.
True/ False

Why are directional terms so important?
They allow us to accurately describe the position of a human body. They allow us to designate specific areas within major body divisions. They enable us to identify an extreme anatomical variation in a human body. They allow us to explain where one body structure is in relation to another.

Which of the following statements is correct?
The heart is posterior to the spine.
The breastbone is ventral to the spine.
The breastbone is posterior to the spine.
The heart is ventral to the breastbone.

Which of the following statements is correct?
The navel is lateral to the chin.
The navel is superior to the chin.
The navel is medial to the chin.
The chin is cranial to the navel.

It is possible for slight anatomical variations to occur in a human body; for example, a nerve or blood vessel may be somewhat out of place, or a small muscle may be missing. True/ False

Which of the following is the regional term designating the limbs? The medial part
The appendicular part
The axial part
The lateral part

The coronal plane divides the body into anterior and posterior parts. True/ False

Which of the following best describes a sagittal plane?
A...
