How does the Respiratory & Circulatory System work together

# data[].attributes.body
The respiratory & circulatory systems work together to transport nutrients, gases,s, and other molecules to and from different parts of the body.

The respiratory system is responsible for the gas exchange in the body. It delivers oxygen to the body and gets rid of carbon dioxide while the circulatory system is responsible for oxygen exchange and nutrient transport to every cell of the body. Moreover, t's also responsible for removing carbon dioxide and other waste from the cell.

Unfiltered air or Oxygen enters through the nose.

# data[].attributes.body
Air is then filtered in the nasal cavity.

# data[].attributes.body
The filtered air will now pass through the pharynx then to the larynx.

# data[].attributes.body
The filtered air will now enter the left & right bronchi then to the bronchioles.

# data[].attributes.body
Then the air will be filtered again in the trachea.

# data[].attributes.body
The air has now reaches the alveoli where the actual gas exchange happens.

# data[].attributes.body
Gas exchange between the blood stream and the alveoli happens when the right ventricle of your heart contracts.

# data[].attributes.body
The blood goes to the 2 pulmonary arteries going to the lungs

# data[].attributes.body
From the alveoli, oxygen enters the bloodstream, which will be carried to the cells of the body, while carbon dioxide leaves the bloodstream and enters the alveoli. The carbon dioxide will exhaled

XI (What happens to the oxygen-rich/oxygenated blood?)

# data[].attributes.body
The oxygenated blood will flow into the pulmonary vein going to the left atrium.

# data[].attributes.body
As the left atrium contracts the oxygenated blood goes to the left ventricle.

# data[].attributes.body
As the left ventricle contracts, oxygenated blood goes through the aorta carrying the blood away from he heart to smaller arteries

# data[].attributes.body
The oxygenated blood is now delivered to all cells of the body

# data[].attributes.body
While delivering oxygen, the blood picks up the carbon dioxide produced by the cells, called deoxygenated blood

# data[].attributes.body
Deoxygenated blood returns through the right atrium through the veins. Deoxygenated blood from the head and neck goes back to the heart through the inferior vena cave

# data[].attributes.body
When deoxygenated blood is delivered tot he heart, the right ventricle contracts. Gas exchange between the alveoli and he blood stream happens again and the cycle continues
