AlexFokin [52]
The path of the blood through the human body follows two pathways. These two pathways are known as the Pulmonary Circulation and Systemic Circulation. Pulmonary circulation is the pathway that deoxygenated blood goes through. It is where blood goes to the lungs to get oxygenated then makes its way to the Systemic Circulation.
