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

Consists of: Liver (detoxification and protein
synthesis) Stomach (1st 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
bloodstream- gas 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 Components
Central Nervous System- Brain and Spinal Cord
Peripheral Nervous System- Connects the body to the CNS
![Page 12: { Body Systems Dividing the body. Provides all body systems with oxygen and nutrients Carries away carbon dioxide and other wastes Circulatory System](https://reader035.vdocuments.us/reader035/viewer/2022070412/5697bf7d1a28abf838c84651/html5/thumbnails/12.jpg)
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
