How does the water vapor (waste) get out of our body? How does the water vapor (waste) get from here…. . Out here? Cells
Remember the equation for cellular respiration! • It requires all 3 body systems for this to occur! Glucose + Oxygen ENERGY + Carbon Dioxide + Water Vapor • Occurs in all cells • Recall how each system contributes to each part of the equation.
How does the sugar get to the cells? • Carbohydrates get broken down in the mouth to sugars by saliva (glucose comes from this). • Nutrients are absorbed in the small intestines through the villi and they go to the blood stream through capillaries.
What transports the sugar to the cells? • The sugar (glucose) is transported to the cells in the plasma of the blood through arteries that branch into capillaries where the sugar enters the cell.
How does the oxygen get to the cells? • O 2 enters the mouth or nose goes to the lungs, where it enters the alveoli, this is where O 2 enters the blood stream(coming from the right ventricle) on its way back to the left atrium. • The alveoli are surrounded by capillaries where the O 2 attaches to a red blood cell.
Getting Oxygen to the cells, continued… • When the oxygenated blood returns to the left atrium and then left ventricle, it is pumped through arteries that eventually lead to capillaries at the cells. This is where the O 2 enters the cell and the CO 2 attaches to the red blood cell on its way to a vein and back to the heart at the right atrium.
Now how does the carbon dioxide and water vapor get out of the body? • As the capillaries branch back into veins the CO 2 on the red blood cell and the water vapor return to the right atrium, then right ventricle which pumps the deoxygenated blood to the lungs. In the alveoli the CO 2 and water vapor leave the capillary and enter the alveoli, they are exhaled.
What happens to the ENERGY? • Energy is used by cells to carry out life functions. For example, as your muscles contract you use energy.
