FAQs on Fun Video: Respiration in Humans Video Lecture - Class 10
| 1. What is respiration in humans? |  |
Ans. Respiration in humans is the process of inhaling oxygen from the atmosphere and exhaling carbon dioxide. It involves the exchange of gases between the body and the environment, which is crucial for the survival and functioning of human beings.
| 2. What are the different types of respiration in humans? | |
Ans. There are two types of respiration in humans: internal respiration and external respiration. Internal respiration refers to the exchange of gases (oxygen and carbon dioxide) between the blood and body tissues, while external respiration involves the exchange of gases between the lungs and the external environment.
| 3. How does respiration occur in humans? | |
Ans. Respiration in humans occurs through a series of steps. It starts with the inhalation of air through the nose or mouth, which travels down the windpipe and enters the lungs. In the lungs, oxygen from the inhaled air is absorbed into the bloodstream, while carbon dioxide is released from the bloodstream into the lungs. Finally, the carbon dioxide is exhaled out of the body through the nose or mouth.
| 4. What organs are involved in the process of respiration in humans? | |
Ans. The organs involved in the process of respiration in humans include the nose, mouth, throat, windpipe (trachea), lungs, and diaphragm. The nose and mouth serve as the entry points for air, which then travels through the throat and windpipe to reach the lungs. The diaphragm, a muscle located below the lungs, helps in the process of breathing by contracting and relaxing.
| 5. Why is respiration important for human beings? | |
Ans. Respiration is vital for human beings as it provides oxygen to the body's cells, which is essential for the production of energy. It also helps in removing carbon dioxide, a waste product, from the body. Without respiration, the cells in our body would not receive enough oxygen, leading to a lack of energy, organ damage, and ultimately, death.
