Chapter 1 - An Introduction to the Human Body

There are only four major organ systems in humans.

Atoms are the smallest independently functioning unit of a living organism.

The frontal plane divides the body into left and right sides.

Catabolism requires energy to build complex substance.

Tissues are more complex than organelles.

MRI is the least invasive form of medical imaging.

Ultrasonography is predominantly used for diagnosing bone fractures.

A CT scan is contraindicated in the presence of internal metallic objects.

If a patient is lying face down, they are said to be in the supine position.

Reproduction is not considered a basic function of human life.

The dorsal cavities consist of the cranial cavity and vertebral cavity.

The epigastric abdominal region is located below the umbilical region.

Responsiveness refers to the ability of an organism to adjust to changes in its internal and external environments.

The visceral pleura directly covers the lungs.

Thermoregulation is an example of a negative feedback loop.

The vertebral column is ventral to the sternum.

The palms are supinated in the anatomical position.

Adenosine triphosphate is the primary energy-carrying molecule in cells.

The ankle is proximal to the knee.

A positive feedback loop reverses a deviation from the set point.

Homeostasis refers to the body’s ability to maintain a stable internal environment.

The study of small body structures is called gross anatomy.

An increase in the number of muscle fibers would be considered hypertrophy.

Systemic anatomy refers to the study of body functions.

The left kidney is found within the LUQ.

A narrow atmospheric pressure range is essential for human life.

Metabolism refers to the sum of all anabolic and catabolic reactions within the body.
