**Diagram Explanation: The Process of Respiratory and Circulatory Systems** The diagram illustrates the interaction between the respiratory and circulatory systems, highlighting the journey of gases like oxygen and carbon dioxide. Here is a detailed breakdown: 1. **Ventilation (1):** - Air is inhaled from the atmosphere into the alveoli of the lungs. 2. **Gas Exchange in the Lungs (2):** - In the alveoli, oxygen from inhaled air diffuses into the blood, while carbon dioxide diffuses from the blood into the alveoli to be exhaled. 3. **Gas Transport (3):** - Oxygen-rich blood travels from the lungs through the pulmonary veins to the left heart. From there, it is pumped via systemic circulation to the rest of the body. 4. **Gas Exchange at Cells (4):** - Oxygen in the blood diffuses into body cells, and carbon dioxide produced by the cells as a waste product diffuses into the blood. 5. **Cellular Respiration (5):** - Cells utilize oxygen to produce energy, resulting in carbon dioxide as a by-product. **Flow Path:** - The **Right Heart** receives deoxygenated blood and pumps it to the lungs through **pulmonary circulation**. - The **Left Heart** receives oxygenated blood from the lungs and pumps it into systemic circulation to supply the body. This cycle ensures a continuous supply of oxygen to the body and the removal of carbon dioxide, supporting overall cellular functions.
