Answer 2

                   Double Circulation in Humans

• The double circulatory system in humans takes place in two pathways – pulmonary and systemic circuit.  
• The “pulmonary circulation” involves the circulation of ‘deoxygenated blood’ from the heart through the "pulmonary artery to the lungs" and oxygenated blood from the lungs through the "pulmonary vein" to the heart.

• The gaseous exchange can take place in the lungs which oxygenates the blood.  
• The systemic circulation involves the circulation of oxygenated blood pumped from the "heart through the aorta" to different body parts.
• Systemic circulation provides 'oxygen and nutrients' to all "parts of the body" through the oxygenated blood.
