Focuses on how carbon dioxide is transported in the blood and the mechanisms that control breathing rate and depth.
Amphibians like frogs use cutaneous respiration, where gas exchange occurs through their moist skin in addition to lungs.

Nitrogen is not involved in the regulation of breathing rate, unlike CO₂, O₂, and blood pH.

The pneumotaxic center, located in the pons, regulates the duration of inspiration and prevents excessive lung expansion.

Carbon dioxide is 20-25 times more soluble in plasma than oxygen, which facilitates its efficient transport.
Ref: NCERT Class 11 Biology Chapter 14: Breathing and Exchange of Gases Transport of Carbon Dioxide and Regulation of Respiration
Carbonic anhydrase is an enzyme that catalyzes the reversible conversion of carbon dioxide and water into carbonic acid, which then dissociates into bicarbonate and hydrogen ions.

Carbon dioxide is 20-25 times more soluble in blood than oxygen, making it easier to transport.

Oxygen levels do influence breathing rate, especially in cases of severe hypoxia.

The respiratory rhythm center in the medulla oblongata regulates the basic rhythm of breathing.

CO₂ transport significantly affects blood pH by forming carbonic acid, which dissociates into bicarbonate and hydrogen ions.

The capillaries surrounding the alveoli facilitate the exchange of oxygen and carbon dioxide between blood and air.
