1. { Body Systems Dividing the body

2.  Provides all body systems with oxygen and nutrients  Carries away carbon dioxide and other wastes Circulatory System

3.  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

4.  Systolic (peak pressure in the arteries)  Diastolic (minimal pressure in arteries) Blood Pressure

5.  Breaks down food into chemicals that the body can use for energy and to maintain cells and tissues Digestive System

6.  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

7.  Carries oxygen from the air to the bloodstream and rids the body of carbon dioxide Respiratory System

8.  Consists of:  Lungs  Bronchi (trachea to lungs)  Bronchial tubes (bronchi to alveoli)  Alveoli (lungs to bloodstream- gas exchange) Respiratory System

9.  Gathers information from the external environment, stores and processes it, and initiates appropriate responses Nervous System

10.  Consists of:  Axon  Dendrite  Neuron- Processes and transmits information by electrical signaling  Brain- Controls all senses Nervous System

11. Nervous System Components   Central Nervous System- Brain and Spinal Cord   Peripheral Nervous System- Connects the body to the CNS

12. Brain   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

13.  Provides the framework and protection for the body  The typical human body has 206 bones Skeletal System

14. Skeletal and Muscular System   A place where two bones connect is called a joint. Pivot Ball and SocketHinge

15. Skeletal and Muscular System Types of Muscle   SMOOTH- makes up your internal organs (stomach and intestine)   CARDIAC- (you better know)   SKELETAL- muscle that attaches bone to bone
