The two organs involved in supplying oxygen to the body.
Answer to Problem 1RCC
Solution:
The two important organs that supply oxygen to the body are the respiratory system and the circulatory system. Both the system works together for the functioning of the body and provide oxygen to it.
Explanation of Solution
The respiratory system obtains oxygen from the atmosphere, by the process of respiration. The gaseous exchange occurs in the lungs in which the oxygen is inhaled, and carbon dioxide is exhaled. By this process, the oxygen enters the blood.
The circulatory system helps in supplying the oxygenated blood to the body parts. Oxygen is transported by the help of red blood cells present in the circulatory system. Red blood cells contain hemoglobin that binds four molecules of oxygen and carries it to the individual cells. Therefore, the respiratory system and the circulatory system work together for the transportation of oxygen.
