Respiratory centre of brain is stimulated by

• A. Carbon dioxide content in venous blood
• B. Carbon dioxide content in arterial blood
• C. Oxygen content in venous blood
• D. Oxygen content in arterial blood

Answer 1

Answer: (B)

Carbon dioxide content in arterial blood

The medulla and the pons are the significant minds focuses that influence breath. The body's respiratory focus in the medulla is typically animated by an expanded convergence of carbon dioxide, and to a lesser degree, by diminished dimensions of oxygen in blood vessel blood.

So, the correct option is 'Carbon dioxide content in arterial blood'.
