What do you mean by pulmonary respiration?

Question

Answer

Pulmonary respiration means the gaseous exchange which take place in lungs. And cellular respiration means that release of energy in cell(mitochondria) by using Oxygen.

Answer

Respiration through lungs are called pulmonary respiration

Answer

Pulmonary through the lungs is kwon as pulmonary respiration
The mechanism of pulmonary respiration its include breathinging movement exchange of gas in lungs transport by blood and exchange of gases by tissue

Answer

External respiration is basically the transfer of gas between respiratory organs such as lungs and blood in pulmonary capillaries. External respiration, also known as breathing, refers to a process of inhaling oxygen from the air into the lungs and expelling carbon dioxide from the lungs to the air. In external respiration, gas exchange takes place between the alveoli and the blood.

Answer

Pulmonary Respiration

Pulmonary respiration refers to the exchange of gases, specifically oxygen and carbon dioxide, between the external environment and the lungs. This process is essential for the survival of aerobic organisms, including humans. Let's delve into the details of pulmonary respiration and understand how it works.

1. Overview of Pulmonary Respiration:
Pulmonary respiration is a vital process that allows the human body to acquire oxygen (O2) from the atmosphere and remove carbon dioxide (CO2) as a waste product. It involves the following key steps:

2. Breathing:
The process of pulmonary respiration begins with breathing, which involves the inhalation and exhalation of air. During inhalation, the diaphragm and intercostal muscles contract, expanding the chest cavity and causing air to rush into the lungs. Exhalation, on the other hand, is a passive process where the diaphragm and intercostal muscles relax, causing the chest cavity to decrease in size and air to be expelled from the lungs.

3. Gas Exchange in the Alveoli:
Once the air enters the lungs, it reaches the alveoli, which are tiny air sacs surrounded by capillaries. Here, the actual gas exchange takes place. Oxygen from the inhaled air diffuses across the thin alveolar walls and into the surrounding capillaries, binding to hemoglobin in red blood cells for transport. At the same time, carbon dioxide, produced as a waste product by cells, diffuses out of the capillaries and into the alveoli to be expelled during exhalation.

4. Transport of Gases:
After the gas exchange in the alveoli, oxygen-rich blood is carried away from the lungs by the pulmonary veins and transported to the heart, where it is pumped to various organs and tissues. Conversely, carbon dioxide-rich blood returns to the heart via the superior and inferior vena cava. It is then pumped to the lungs once again for elimination through exhalation.

5. Cellular Respiration:
Once oxygen is delivered to the cells, it participates in cellular respiration. This process occurs in the mitochondria, where oxygen acts as the final electron acceptor in the electron transport chain, generating ATP (adenosine triphosphate), which provides energy for cellular activities. As a result, carbon dioxide is produced as a byproduct and transported back to the lungs for elimination.

Conclusion:
Pulmonary respiration is a complex process involving breathing, gas exchange in the alveoli, transport of gases, and cellular respiration. It plays a crucial role in maintaining the oxygen supply required for the proper functioning of cells and removing carbon dioxide, a waste product of cellular metabolism. Understanding the intricacies of pulmonary respiration helps us appreciate the remarkable synergy between the respiratory and circulatory systems in supporting human life.
