Cardio vascular system
Pulmonary circulation
-

The part of blood circulation which carries deoxygenated blood away from the
heart, to the lungs, and returns the oxygenated blood back to the heart
...
Then the blood is them pumped through the tricuspid
valve into the right ventricle
...
The pulmonary artery splits into the right and left pulmonary arteries and travels to
each lung
...
The alveoli are air sacs in
the lung that provide the surface for gas exchange during respiration
...

Once entering the left atrium, the blood flows through the bicuspid valve into the left
ventricle

Pulmonary circulation is also known as the external respiration (c02 swapped for 02)
Systemic circulation is also known as the internal respiration (02 swapped for c02)

Systemic circulation is the movement of blood from the heart through the body to provide
oxygen and nutrients and brining deoxygenated blood back to the heart
...
The blood is then pumped through the mitral valve into the left ventricle
...
The aorta arches and branches into major arteries to the upper body
before passing through the diaphragm, where it branches further into arties which supply
the lower parts of the body
...
Waste and carbon
dioxide diffuse out of the cell into the blood, while oxygen in the blood diffuses out of the
blood and into the cell
...

From the right atrium, the blood will travel through the pulmonary circulation to be
oxygenated before returning to the system circulation
