The normal respiratory rate in a healthy resting adult is around 12-16 breaths per minute.
Ref: NCERT Class 11 Biology Chapter 14: Breathing and Exchange of Gases Respiratory Disorders - Asthma Emphysema Occupational Disorders
Carbon dioxide is the primary stimulus for respiration as it affects blood pH and triggers the respiratory center in the medulla.
Ref: NCERT Class 11 Biology Chapter 14: Breathing and Exchange of Gases Respiratory Disorders - Asthma Emphysema Occupational Disorders
About 70% of carbon dioxide is transported in the form of bicarbonate ions (HCO3-) in the blood.
Ref: NCERT Class 11 Biology Chapter 14: Breathing and Exchange of Gases Respiratory Disorders - Asthma Emphysema Occupational Disorders
Carbon dioxide is 20-25 times more soluble in plasma than oxygen, which facilitates its efficient transport.
