When you breathe in oxygen, what happens? How does oxygen get to the tissues of your body? (USE YOUR OWN WORDS)​

When you breathe in oxygen, your diaphragm pushes against itself and pulls downwards. The muscles between the ribs pull upwards. The oxygen gets into the tissues by being helped by red blood cells and has a pigment that collects four oxygen molecules. It forms into a thing known as oxyhaemoglobin and the molecules are taken to other singular cells in the body tissue, releasing its contents.
