Welcome to the NCERT Solutions for Class 11 Biology - Chapter Breathing and Exchange of Gasses. This page offers a step-by-step solution to the specific question from Exercise 0, Question 3:
Explain the role of neural system in regulation of respiration.
. With detailed answers and explanations for each chapter, students can strengthen their understanding and prepare confidently for exams. Ideal for CBSE and other board students, this resource will simplify your study experience.Explain the role of neural system in regulation of respiration.
Regulation of respiration occurs under the dual control: Nervous and Chemical. Here, we will discuss about the nervous control.
Nervous control: Normal breathing is an involuntary process. Human breathe about 12 times in a minute, but infants breathe about 44 times in a minute. This steady rate is controlled by group of neurons located in the medulla oblongata and pons varolii.
The respiratory centre, regulates the rate and the depth of breathing which is divided into three major group of neurons: Dorsal respiratory group (this causes inspiration), ventral respiratory group (this causes expiration) and pneumotaxic centre (sends signal to all the neurons of dorsal respiratory group and only to inspiratory neurons of ventral respiratory group, it limits inspiration).
