The organs and organ components that work together to enable us to breath.

Breathing is the exchange of oxygen and carbon dioxide to and from our body.

Oxygen Carbon dioxide

With every breath, more than 15 ounces (500 ml) of air is taken into the lungs.

The Lungs are spongy organs The Lungs rest on the diaphragm, a muscle

that helps with bringing in and pushing out air

The Lungs provide the meeting site between Capillaries and Alveoli

The diaphragm acts as a partition between the cavity of the chest and that of the abdomen.

It is the chief muscle used in respiration, it is relaxed and dome-shaped during exhalation.

During inhalation it contracts, pulling downward, and with the combined contraction of the chest muscles allows the chest cavity to expand.

Oxygen is transferred to capillaries that carry red blood cells from the Lungs to Heart. From the Heart, the oxygen rich blood is circulated throughout the body.

Carbon dioxide is a waste product made in our body

Blood cells deliver Carbon dioxide to the Lungs where it travels out from the body

Capillaries are delicate vessels with fine walls that facilitate the exchange of gases between the blood and the tissues.

The main function of red blood cells, or erythrocytes, is transporting oxygen to the cells.

Red blood cells contain a molecule called hemoglobin, to which oxygen binds until it reaches its destination.
