Question

what is physical and chemical factors affecting Breathing

Answer 1

Breathing is a necessary function for human beings. It supplies oxygen for a process called cellular respiration, which is how cells manufacture the energy they need for their life functions. There are lots of things that can affect the rate of breathing in humans. Exercise is one of those things, particularly aerobic exercise. Aerobic exercise is any exercise that causes the person to breathe more, such as running, jogging, playing basketball, football, running track, or playing soccer. Another factor that can influence breathing rate is allergic reactions to stimuli from the environment, such as pollen. This can inflame the passageways leading to the lungs, making them smaller, requiring more air. Smoking is a habit that can influence the development of lung cancer, which in turn influences the rate a person breathes.

ANSWER

1 :) CHEMICAL FACTOR AFFECTING BREATHING :-


there are so many factors which affect the activity of respiratory centre . respiratory centre is sensitive to co2 - concentration in the blood and ph of blood . respiratory centre is not sensitive for o2 - concentration in blood . whenever in the blood , co2 concentration is increased , or ph is decreased , or acidity is increased , then respiratory centre becomes more activated and increases the rate of respiration . normal breathing rate of rabbit is 36- 38 per minute . for adults human it is 14 - 18 per minute.


====================================


2:) PHYSICAL FACTORS AFFECTING BREATHING :-

the activity of respiratory centre is also affected by body temperature and blood pressure. whenever body temperature is increased or blood pressure goes high, respiratory centre becomes more activated and this increases the respiration rate.
