Overview * The human body itself is a complex system—many sets of interacting parts that work to keep the human machine running. On any single day, we can estimate that your heart beats 103,689 times, your blood travels 168,000,000 miles, your digestive

* The lower extremity - composed of the bones of the thigh, leg, foot, and the patella (commonly known as the kneecap). * The Shoulder Girdle (also called the Pectoral Girdle) - composed of four bones: two clavicles (collarbones) and two scapulae (shoulder blades). * The Pelvic Girdle (also called the hip girdle) - composed to two coxal (hip) bones.

Muscular System
Over 600 skeletal muscles function for body movement through contraction and relaxation of voluntary, striated muscle fibers. These muscles are attached to bones, and are typically under conscious control for locomotion, facial expressions, posture, and other body movements. Muscles account for approximately 40 percent of body weight. The metabolism that occurs in this large mass-produces heat essential for the maintenance of body temperature

Types of Muscles
The types of muscles are: * Cardiac muscle * Smooth muscle * Skeletal muscle

Cardiac Muscle * Cardiac muscle is only in the heart and makes up the atria and ventricles (heart walls). Like skeletal muscle, cardiac muscle contains striated fibers. Cardiac muscle is called involuntary muscle because conscious thought does not control its contractions. Specialized cardiac muscle cells maintain a consistent heart rate.
Smooth muscle * Smooth muscle is throughout the body, including in visceral (internal) organs, blood vessels, and glands. Like cardiac muscle,
