Anatomy -

Study of the body structure.

Physiology-

Study of how the body functions

The basic units of all life -

Cells

What are the 11 body systems?

Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cardiovascular, Lymphatic, Respiratory, Digestive, Urinary, Reproductive

Homeostasis -

Maintaining a state of internal balance within the body.

Any feedback loop must contain 3 components:

sensor, control center, effector

A sensor-

gathers information about a body's condition

An effector-

responds to the signal

A control center-

compares the sensor inputs with the set point and sends a corrective signal if necessary

Body Directional Terms -

healthcare professionals use standardized terms to designate body positions and directions.

Anatomic Position -

standing upright with face front, arms at sides with palms facing forward, and feet parallel.

Anterior and Ventral:

toward the belly surface, or front of the body

Posterior and Dorsal-

locations nearer the back

Body Cavities:

Dorsal cavity, Ventral cavity, Cranial cavity, Spinal cavity, Thoracic cavity, Abdominal cavity, Abdomio-pelvic cavity, Pelvic cavity

4 Quadrants of the Abdomen-

RUQ (right upper quadrant), LUQ (left upper quadrant), LLQ (left lower quadrant), RLQ (right lower quadrant

9 Regions of the Abdomen-

Cells

Basic units of all life.

Organs-

work together to form systems
