Dicuss the Neural control of breathing in animal
Step by step
Solved in 3 steps
- Regulation of breathing rate Label the figure below to indicate how breathing rate is regulated. Not all labels will be used. Oxygen in blood is too high Oxygen in blood is too low Breathing rate increases Blood becomes too basic Carbon dioxide in blood is Carbon dioxide in blood is too high Carbon dioxide in blood is too low Thalamus detects change normal Blood becomes more acidic Blood flow to lungs increases Oxygen in blood is normal Medulla detects change Carbon dioxide concentration decreases Resetexplain neural regulation (respiration)Parasympathethic stimulation of the lungs causes bronchi to dilate bronchioles to dilate bronchi to constrict bronchioles to constrict
- Which group of animals bidirectional flow rather than unidirectional flow to move water or air across its respiratory surfaces? mammals birds sharks using ram ventilation fish using buccopharyngeal pumpingWhat neural afferents might also contribute to the regulation of ventilation during exercise?Discuss the importance of the contraction and relaxation of the mammalian diaphragm in breathing.
- In control of ventilation, which of the following is the most important? PCO2 in the blood PO2 in the blood PO2 in the inspired air PCO2 in the inspired airWhat is the role of carbon dioxide in the control of rate and depth of mammalian breathing?Outline how chemoreceptors influence ventilation and heart beat in mammals.
