CHAPTER 3 ANATOMY AND PHYSIOLOGY | BASIC BODY SYSTEMS | THE MUSCULAR SYSTEM
Muscles produce movement through contraction (tightening) and expansion (relaxing)7 ways to stimulate muscular tissue include:1. Massage2. Electric current (high-frequency and faradic current)3. Light rays (infrared rays and ultraviolet rays)4. Heat rays (heating lamps and heating caps)5. Moist heat (steamers, warm steam towels)6. Nerve impulses (through nervous system)7. Chemicals (certain acids and salts)

BLOOD VESSELS
CHAPTER 3 ANATOMY AND PHYSIOLOGY | BASIC BODY SYSTEMS | THE CIRCULATORY SYSTEM | THE CARDIOVASCULAR SYSTEM
Arteries Veins Capillaries• Tubular, elastic,
thick-walled• Branching vessels• Carry blood away
from heart• Carry pure blood
(bright red in color)

FACE THE FACTSTHE RESPIRATORY SYSTEM The respiratory system is responsible for the intake of
oxygen to be absorbed into the blood and the exhalation of carbon dioxide
THE ENDOCRINE SYSTEM The endocrine system is composed of a group of
specialized ductless glands that regulate and control the growth, reproduction and health of the body

LESSONS LEARNED The building blocks of the human body include cells that
make up tissues, tissues that make up organs and organs that make up systems
The skeletal system supports the body, surrounds and protects internal organs, provides a frame to which muscles can attach and allows body movement
The muscular system supports the skeleton, produces body movements, contours the body and aids in the functions of other body systems

LESSONS LEARNED The circulatory system controls the circulation of
blood and lymph through the body The nervous system coordinates and controls the
overall operation of the human body by receiving and interpreting stimuli and sending messages away from the nerve cells to the appropriate tissues, muscles and organs
