Question

explain human respiratory system in detail ( class 10)​

Answer 1

Answer:

The human respiratory system is a series of organs responsible for taking in oxygen and expelling carbon dioxide. The primary organs of the respiratory system are the lungs, which carry out this exchange of gases as we breathe. 

The lungs work with the circulatory system to pump oxygen-rich blood to all cells in the body. The blood then collects carbon dioxide and other waste products and transports them back to the lungs, where they're pumped out of the body when we exhale, according to the American Lung Association.

The human body needs oxygen to sustain itself. After only about five minutes without oxygen, brain cells begin dying, according to the National Institute of Neurological Disorders and Stroke, which can lead to brain damage and ultimately death.

Answer 2

Answer:

“Human Respiratory System is the organ system that involves inhaling of oxygen and exhaling of carbon dioxide to meet the energy requirements.” When we breathe, we inhale oxygen and exhale carbon dioxide. The so-called exchange of gases is necessary for metabolic activities and can be considered a chemical process.
