It gets to the cells from the lungs. For the oxygen to get to the lungs, people need to inhale it and it needs go down the trachea.

Then, the lungs transfer the oxygen to the red blood cells in the blood stream. The cell picks

up the oxygen from the red blood cells and delivers it to the hand.

The lung tissues, epithelial tissue, and red blood tissues.

The lung tissue helps bybreathing in the oxygen.

The epithelial tissuehelps because it

protects the other important organs

that deliver the oxygen.

The red blood tissuehelps by carrying the

oxygen in the blood tothe cell.

The lungs and the trachea, the heart, skin and the blood vessels.

They help because they deliver he

inhaled oxygen to the blood stream.

The heart helps because it pumps the blood that

delivers the oxygen.

The blood stream because

it carries the oxygen to the

cells.

The skin protects the organs while sending the

oxygen to the needed cells.

The Respiratory System and Circulatory Systems.

The respiratory system helps by inhaling the oxygen and then

passing it on to the bloodstreamand circulatory system.

The circulatory system helps pump the blood, which

contains the oxygen the cells need, throughout the body.
