Question

plss tell me the answer which you know.... pls don't copy from google.... give the answers in 1 line​

Answer 1

Answer:

1)we breathe through nose which is used to inhale oxygen and internally lungs help us to exhale carbon dioxide.

2)the muscles that are involved in breathing are diaphragm and muscles between our ribs.when we breathe our diaphragm contracts and move downwards that increases the space between our ribs and enlarge our chest cavity.they contract to pull our rib cage both upward and downward when we inhale.

3)the types of breathing are inhalation and exhalation.

• the process of taking in oxygen from the air known as inhalation.
• the process of breathing out the carbon dioxide and other gases known as exhalation.

Answer 2

Answer:

1. Breathing uses chemical and mechanical processes to bring oxygen to every cell of the body and to get rid of carbon dioxide. Our body needs oxygen to obtain energy to fuel all our living processes.
2. 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. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
3. There are two main types of breathing : costal (meaning “of the ribs”) or chest breathing, and diaphragmatic or abdominal breathing. Only when we take a maximum breath is a third variety used, known as clavicular breathing.
4. In the picture
5. the return of ease in breathing after exhaustion caused by continued physical exertion, as in running. the energy for a renewed effort to continue an undertaking. Symptoms-Brownish red urine, especially after periods of activity
6. Easily tiring during activity, with stiffness or weakness soon after starting exercise
7. Muscle cramping
8. Muscle pain
9. Permanent weakness in the thigh or other muscles. This happens in a small portion of people with the condition.
10. Vital capacity: the volume of air breathed out after the deepest inhalation. Tidal volume: that volume of air moved into or out of the lungs during quiet breathing (VT indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or VT is used.)
11. The amount of oxygen required to remove the lactic acid, and replace the body's reserves of oxygen, is called the oxygen debt. When someone who has been exercising pays back an oxygen debt, it can take from a few hours for normal exercise, to several days after a marathon.
