Q) 1. Compare inspiration and expiration in human beings.
Q) 2. Clinical examinations use ‘Spirometer’ as one of the tools for diagnosis.
Explain.
Q) 3. Make a note on respiratory volumes and capacities.
Answers
Answer:
answer 1)
- Inspiration in human beings:
Inspiration is the process in which we take the air inside the lungs. During this process the lifting of ribs and flattening of the diaphragm takes place. Due to this size of the thoracic cavity increases and pressure inside the lungs remain low as compared to atmospheric pressure and we inhale the air. This process is called inspiration.
- Expiration in human beings:
Expiration is the process in which we exhale the air outside our lungs. During this process relaxation of the lungs and diaphragm takes place. Due to this the size of thoracic cavity decreases and pressure inside the lungs is higher as compared to atmospheric pressure and as a result we exhale the air outside the lungs. This process Is called expiration.
answer 2)
Spirometry (spy-ROM-uh-tree) is a common office test used to assess how well your lungs work by measuring how much air you inhale, how much you exhale and how quickly you exhale. Spirometry is used to diagnose asthma, chronic obstructive pulmonary disease (COPD) and other conditions that affect breathing.
answer 3)
The vital capacity (VC) measures the maximum amount of air that can be inhaled or exhaled during a respiratory cycle. It is the sum of the expiratory reserve volume, tidal volume, and inspiratory reserve volume. The inspiratory capacity (IC) is the amount of air that can be inhaled after the end of a normal expiration.

Answer:
1 ans When the lungs inhale, the diaphragm contracts and pulls downward. ... As a result, air rushes in and fills the lungs. The second phase is called expiration, or exhaling. When the lungs exhale, the diaphrag relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases.
2 ans The processes of inspiration (breathing in) and expiration (breathing out) are vital for providing oxygen to tissues and removing carbon dioxide from the body. Inspiration occurs via active contraction of muscles such as the diaphragm whereas expiration tends to be passive, unless it is forced
3 ans Under normal conditions, the average adult takes 12 to 15 breaths a minute. A breath is one complete respiratory cycle that consists of one inspiration and one expiration.
Under normal conditions, the average adult takes 12 to 15 breaths a minute. A breath is one complete respiratory cycle that consists of one inspiration and one expiration.An instrument called a spirometer is used to measure the volume of air that moves into and out of the lungs, and the process of taking the measurements is called spirometry. Respiratory (pulmonary) volumes are an important aspect of pulmonary function testing because they can provide information about the physical condition of the lungs.

Lungs usually reach their maximumin capacity in early adulthood and decline with age after that.
