Question

Do humans breathe automatically?

Answer 1

Some things cannot be taught, such as our very first survival instinct, our first breath. Our lungs were never taught to breathe properly. It's incredible that one doesn't need to learn how to smell, see, or breathe to perform any of these functions. Whether or not we understand the mechanism of these involuntary functions, it is imperative that we comprehend its functioning since these are mechanisms that facilitate our survival.

Complete answer:
Breathing refers to the movement of air into and out of the lungs. This is accomplished through the use of various respiratory organs. To put it another way, breathing is a simple give and take process. When we breathe, we take in oxygen-rich air from the atmosphere and expel carbon dioxide-rich air into the atmosphere, which plants use for photosynthesis.

Inhalation is the process of taking in oxygen-rich air. Exhalation, on the other hand, is the process of exhaling carbon dioxide-rich air. A person breathes several times throughout the day. One breath is made up of one inhalation and one exhalation. The number of times a person breathes in a minute is referred to as his or her breathing rate. We can learn about the breathing rate by calculating the number of times we breathed in a day.

Breathing is typically automatic, with the respiratory center at the base of the brain controlling it subconsciously. Breathing continues while sleeping and, in most cases, even when a person is unconscious. People can also control their breathing when they want, such as while speaking, singing, or holding their breath.

Thus, breathing is automatic and regulated by the autonomic nervous system.

Note: The breathing rate varies according to a person's activity. It rises when a person is brisk walking, running, or recovering from a strenuous exercise; conversely, it falls when a person is calm. An adult's breathing rate is 15-18 times per minute. During strenuous exercise, however, the breathing rate exceeds 25 times per minute.
