Systems of the Human Body Skin Skeletal Muscular Digestive Circulatory Respiratory Excretory Nervous Reproductive Endocrine

Three main areas of the Human Body Cranial cavity (head) - brain Thoracic cavity (chest) - heart and lungs Abdominal – stomach, intestines, liver, pancreas, kidneys, bladder, and reproductive organs

The Heart Strong muscle tissue which acts as a pump for our blood

Respiratory Includes nasal cavity, pharynx, larynx, trachea, lungs, and alveoli. This system works to provide air to the lungs and alveoli, which exchange the gases (co 2, O 2 )within the blood. Circulatory Includes both cardiovasular and lymphatic system Main parts are heart and blood vessels. Systemic circulation provides the body with oxygenated blood. vs
