Question

how is respiration regulated ?

Answer 1

human beings have a significant ability to maintain and moderate the respiratory Rhythm to suit the demands of the body tissue is is done by the neural system the specialised Centre present in the middle region of the brain call respiratory Rhythm Centre is primarily responsible for this regulation another Centre present in the pons region of the brain called the pnemotoxicentre can moderate the functions of the respiratory Rhythm Centre .neural signals from this centre can reduce the duration of inspiration and thereby alter the respiratory rate
a chemosensitive area is situated adjacent to the rhythm Centre which is highly sensitive to carbon dioxide and hydrogen ions increase in these substances can active the centre which in turn can signal the rhythm Centre to make necessary adjustment in the respiratory process by which these substances can be eliminated receptors associated with aorotic arch and carotid artery also can recognise changes in carbon dioxide and H +ion concentration and send necessary signals to the rhythm Centre for remedial action the role of oxygen in the regulation of the respiratory rhythm is quite insignificant

________________

$<b><i>$Respiration is the biochemical process in which living organisms inhale oxygen and exhale carbon dioxide. medulla is the part of the human brain and pons is the part of the human brain too they both are responsible for the regulation of the respiration. In brain there are neuron signals which are transmitted .

$<b><i>$In respiration inhalation is followed by exhalation and it happens in a regular period known as respiratory rhythm .There is the region in medulla which regulate rhythm .Respiratory rhythm centre which send impulses is responsible for inspiration .Exhalation happens on the relaxation of the muscles .
