Question

The number of times a person breathes in a minute is called as
(A) Inhalation
(B) Respiratory rate
(C) Breathing
(D) Breathing rate

Answer 1

Hint: It's the rate typically calculated by counting the number of times the chest is rising or dropping each minute.

Complete answer:Respiration is vital because it generates energy which is necessary for the body's normal functioning. It delivers oxygen to cells, and it expels poisonous carbon dioxide. That means oxygen is taken up and carbon dioxide is released. The respiratory system's main organs include the nose, lungs, pharynx, trachea, larynx , bronchi, and diaphragm.
Now lets us find the solution from the given options-
1. Inhalation is a process of breathing in. When an individual inhales, the diaphragm and the muscles between the ribs contract and widen the chest cavity.
2. Respiratory rate is the rate at which respiration occurs. This is generally measured in breaths per minute. For a resting adult, a normal respiratory rate can vary based on age and activity but is typically between 12 and 20 breaths per minute.
3. Breathing is the method of bringing air into and out of the lungs to allow gas exchange with the environment, often by oxygen intake and carbon dioxide flushing out.
4. Respiratory rate is known as breathing rate.

Thus, the right answer is option B and D i.e., Respiration rate and Breathing rate

Note: For humans, the average respiratory rate for a healthy person at relaxation is 12–18 breaths per min. The respiratory centre establishes the respiratory rhythm at about three seconds for an exhalation and two seconds for inhalation. This gives 12 breaths per minute the lower of the average rate.
