D.Less \[{{O}_{2}}\] in blood

Answer 1

Hint: Deep abdominal respiration facilitates total exchange of oxygen, i.e. the advantageous trade of incoming oxygen for outgoing carbon dioxide. Not unexpectedly, the heartbeat is slowed by this form of breathing and can lower or maintain blood pressure.

Complete answer:
Blood does not get saturated with oxygen by more than 100%. More carbon dioxide is washed out of the blood during deep breathing. In red blood cells, this helps oxygen cling more closely to haemoglobin and therefore the supply of oxygen to the tissues is made worse and causes oxygen toxicity. However, higher levels of carbon dioxide will enhance the delivery of oxygen in comparison. The lungs thus retain high levels of carbon dioxide in inhaled air and thus in the blood.

While breathing deeply can sound uncomfortable, the practise comes with various advantages. Deep breaths are more effective: they allow your body to exchange incoming oxygen and outgoing carbon dioxide completely. They have also been shown to slow the heartbeat, lower blood pressure or regulate it and lower stress.
Find a quiet place to sit or lay down in order to experience deep breathing. Breathe through your nose slowly and deeply, causing your stomach to rise and expand. Completely exhale.

Breathing deep for a minute is not going to increase the capacity of your lungs. But a healthy way to decrease tension and relax is deep breathing.

Hence, the correct answer is option (C)

Note: Asthma, which causes the airways to narrow and create extra mucus, is one common condition that affects the respiratory system, making it hard to transfer air into the lungs.
With asthma, the air in your lungs is harder to get out. If you start breathing fast, you can bring more oxygen into your lungs. You can't take a big breath in then.
