Have you heard about hypoxia? Try to gather information about it, and discuss with your friends. |
|
Answer» Hypoxia is a condition characterised by an inadequate or decreased supply of oxygen to the lungs. It is caused by several extrinsic factors such as reduction in `pO_(2)`, inadequate oxygen, etc. The different types of hypoxia are discussed below. Hypoxemic hypoxia In this condition, there is a reduction in the oxygen content of blood as a result of the low partial pressure of oxygen in the arterial blood. Anaemic hypoxia In this condition, there is a reduction in the concentration of haemoglobin. Stagnant or ischemic hypoxia In this condition, there is a deficiency in the oxygen content of blood because of poor blood circulation. It occurs when a person is exposed to cold temperature for a prolonged period of time. Histotoxic hypoxia In this condition, tissues are unable to use oxygen. This occurs during carbon monoxide or cyanide poisoning. |

Neural signal from which centre can reduce the duration of inspiration isA. Chemosensitive areaB. Respiratory rhythm centreC. Pneumotaxic centreD. Receptors associated with aortic arch and carotid artery |
|
Answer» Correct Answer - C Acentre present in the pons region of the brain called pneumotaxic centre can moderate the iimctions of the respiratory rhythm centre. Neural signal from this centre can reduce the duration of inspiration and thereby alter the respiratory rate. In human beings, in each breath, inspiration accounts for 2 seconds and expiration accounts for 3 seconds. When the pneumotaxic centre is more active, breathing rate is more rapid. |
