What do the organs of respiratory to help body?
The respiratory system helps the body by doing following things :
1. Gas Exchange: The primary function of the respiratory system is to facilitate gas exchange between the body and the environment. It allows oxygen (O2) to enter the bloodstream and carbon dioxide (CO2), a waste product of cellular metabolism, to be removed from the body.
2. Breathing: The respiratory system enables the process of breathing, which involves the inhalation and exhalation of air. Inhaling brings oxygen-rich air into the lungs, while exhaling releases carbon dioxide.
3. Oxygen Delivery: The respiratory system transports oxygen from the lungs to the bloodstream, where it can be carried by hemoglobin to various tissues and cells throughout the body.
4. Carbon Dioxide Removal: The respiratory system removes carbon dioxide from the bloodstream and exhales it out of the body. This helps maintain the proper balance of gases in the body.
5. Regulation of pH: The respiratory system plays a role in regulating the body's pH level by controlling the amount of carbon dioxide in the blood. Increased carbon dioxide levels can cause the blood to become more acidic, while decreased levels can make it more alkaline.
6. Voice Production: The respiratory system is involved in the production of sound and speech. The vibration of vocal cords in the larynx (voice box) generates sound, which is then modified by the structures of the mouth, nose, and throat to produce different vocal sounds.
7. Olfaction: The respiratory system contributes to the sense of smell by allowing certain chemicals in the air to reach the olfactory receptors in the nasal cavity. This enables us to detect and distinguish different odours.
8. Thermoregulation: The respiratory system helps regulate body temperature by adjusting the rate and depth of breathing. Sweating, which is triggered by the respiratory system, also plays a role in temperature regulation.
9. Humidification of Air: The respiratory system humidifies the air we inhale, which helps protect the delicate tissues of the lungs from drying out.
10. Protection from Foreign Substances: The respiratory system acts as a barrier against harmful substances in the environment. It filters out dust, pollen, bacteria, and other particles, preventing them from entering the lungs and causing infections or respiratory issues.
Overall, the respiratory system plays a vital role in supporting life and maintaining homeostasis within the body.
