The methods involved in it:

1. Oxygen supply to the cells: Transportation
2. Release of carbon dioxide to the atmosphere from the cells during the process of transportation in humans: Respiration

Transportation:

• The circulatory system is involved in the transportation.
• The human circulatory system is a double system.
• The blood flows from two different circulations known as pulmonary circulation and systemic circulation.
• The right side of the heart pumps blood to the lungs which returns to the left side of the heart.
• The left side of the heart pumps blood to rest of the body which returns to the right side of the heart.
• In the pulmonary system, gaseous exchange takes place Oxygen and eliminate carbon dioxide.
• In the systemic system, the blood is pumped under high pressure to all the parts of the body. The supply of oxygen and nutrients take place where as carbon dioxide and other waste are taken up.

Respiration:

• The process of breakdown of food into glucose for the regular working of cells and the whole body is called respiration.
• There are two types of respiration namely aerobic and anaerobic respiration.
• Aerobic respiration is a type of respiration that takes place in the presence of oxygen.
• Aerobic respiration produces more energy and the products are carbon dioxide, water and energy.
• Anaerobic respiration takes place in the absence of Oxygen and produces less energy.
• The and products produced here are lactic acid, ethanol and energy.
