Stomach

Eat food with nutrients in it (protein and carbohydrates)

Stomach digests food and enzymes turn part of the protein into amino acids

The protein (nutrients) pass through the intestines and

into the bloodstream

The blood gives different cells the proteins they need

to survive

The enzymes in the stomach break down the food and separate the nutrients

The fat passes through the intestines and into the bloodstream

The blood brings the fat (sugar & carbohydrates) to the needy cells

Trachea

1. We breathe in.

2. The oxygen then goes down the trachea into the lungs.

3. The lungs then give oxygen to bloodstream…

4. And the bloodstream delivers the oxygen to cells.

Unused nutrients are given to the bloodstream from the cell.

The blood bring the nutrients to the small intestine.

The small intestine scans for any protein or important nutrients that were still in the solid clump.

The solid waste then leaves the intestine and goes into the large intestine.

Nerve cells communicate with the brain to tell the body to go to the bathroom.

The cells get oxygen from the circulatory system. In return the cell gives carbon dioxide, used oxygen, back to the red blood cell. The circulatory system takes back all the carbon dioxide to the lungs to breathe out. This is a non-stop process and goes on throughout your life.

Tissue- made of the same cells

working together.

Organ- made of different tissues

working together.

Organ System- made of different organs working

together.

Cells, tissues, organs, and organ systems make up our body by working together.
