Answer 1

Answer:

Respiratory rate: A person's respiratory rate is the number of breaths you take per minute. The normal respiration rate for an adult at rest is 12 to 20 breaths per minute.

The human trachea (windpipe) divides into two main bronchi (also called mainstem bronchi), at the anatomical point known as the carina. The right main bronchus is wider and shorter than the left main bronchus.

Most of the living organisms carry out aerobic respiration (by using oxygen of air), and such organisms are called aerobes. For example, humans, dogs, ... Aerobic respiration produces much more energy because the complete breakdown of glucose (food) occurs during aerobic respiration by the use of oxygen.

When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. ... They contract to pull your rib cage both upward and outward when you inhale.
