Body Systems Dividing the body Provides all body
Body Systems { Dividing the body
Provides all body systems with oxygen and nutrients Carries away carbon dioxide and other wastes Circulatory System
Consists of: Blood (oxygen source for the body) Heart (pumps blood throughout the body) Arteries (carry blood away from heart) Veins (carry blood to the heart) …. Continued
Systolic (peak pressure in the arteries) Diastolic (minimal pressure in arteries) Blood Pressure
Digestive System Breaks down food into chemicals that the body can use for energy and to maintain cells and tissues
Consists of: Liver (detoxification and protein synthesis) Stomach (1 st step of digestion after chewing) Small Intestine (where MOST digestion takes place) Large Intestine (absorbs water and pass useless waste through the body) Digestive System
Carries oxygen from the air to the bloodstream and rids the body of carbon dioxide Respiratory System
Consists of: Lungs Bronchi (trachea to lungs) Bronchial tubes (bronchi to alveoli) Alveoli (lungs to bloodstreamgas exchange) Respiratory System
Gathers information from the external environment, stores and processes it, and initiates appropriate responses Nervous System
Consists of: Axon Dendrite Neuron. Processes and transmits information by electrical signaling Brain- Controls all senses Nervous System
Central Nervous System. Brain and Spinal Cord Peripheral Nervous System - Connects the body to the CNS Nervous System Components
Cerebrum- Largest part of the brain. Controls all senses and emotions Cerebellum- Second largest. Controls muscle coordination, balance, and posture Brainstem- Connects to spinal cord. Controls heart rate, blood pressure, and breathing Brain
Skeletal System Provides the framework and protection for the body The typical human body has 206 bones
A place where two bones connect is called a joint. Pivot Ball and Socket Skeletal and Muscular System Hinge
Types of Muscle SMOOTH- makes up your internal organs (stomach and intestine) CARDIAC- (you better know) SKELETAL- muscle that attaches bone to bone Skeletal and Muscular System
