To the left, is a picture of 6 of the main systems in the human body. These systems try their hardest everyday to make sure we survive day to day. In this unit we learned how hard our body works and functions to help us do what we need and love to do.

This resource leads to a prezi presentation about how the circulatory, digestive, and respiratory system work together.
When you press the resource 2 button, you will be lead to a website that explains the parts and the functions of the Nervous System.
Resource 3 takes you to a YouTube video that explains how the immune system protects our body from viruses.
Digestive, Respiratory, and Digestive System
The purpose of your digestive system is to take in food from your environment and break it down. Through the process of digestion, you break large nutrient molecules into smaller ones that your intestine absorbs into the bloodstream. Cells then take up these nutrient molecules and use them to build new molecules and provide for their cellular energy needs. Cells can also store the molecules for later use.Your respiratory system takes in oxygen from the atmosphere and moves that oxygen into the bloodstream by allowing it to move across the membranes of the lungs into the blood vessels. The circulatory system then carries oxygen to all the cells in the body and picks up carbon dioxide waste, which it returns to the lungs. Carbon dioxide diffuses from the blood into the lungs, and you exhale it into the atmosphere. Like a network of roads, the job of the circulatory system is to allow the transport of materials from one place to another.
Nervous System
Neurons in the brain communicate via electrical impulses and neurotransmitters. The nervous is a collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring.The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
Immune System
The immune system is the body's defense against infectious organisms and other invaders. Through a series of steps called the immune response, the immune system attacks organisms and substances that invade body systems and cause disease.The immune system is made up of a network of cells, tissues, and organs that work together to protect the body. One of the important cells involved are white blood cells, also called leukocytes, which come in two basic types that combine to seek out and destroy disease-causing organisms or substances
