प्रश्न
What would be the consequences of a deficiency of haemoglobin in our bodies?
Advertisements
उत्तर १
Haemoglobin is the respiratory pigment that transports oxygen to the body cells for cellular respiration. Therefore, a deficiency of haemoglobin in the blood can affect the oxygen supplying capacity of the blood. This can lead to a deficiency of oxygen in the body's cells. It can also lead to a disease called anaemia.
उत्तर २
The deficiency of haemoglobin in our bodies would reduce the oxygen carrying capacity of the blood, resulting in breathing problems, tiredness and a lack of energy. Due to this, we would look pale and lose weight. Our blood contains a red pigment called haemoglobin, which distributes oxygen throughout the body. Anaemia is a condition caused by a lack of haemoglobin, which lowers the amount of oxygen that reaches our body's cells and may cause our body to release less energy. The signs of anaemia include weakness, exhaustion, and dyspnea. Additionally, a lack of haemoglobin will reduce red blood cells' ability to deliver oxygen from the lungs to the body's tissues, which results in hypoxia. As a result, the organism's energy supply and metabolic rate are reduced.
