What would be the consequences of a deficiency of haemoglobin in our bodies?
Advertisements
उत्तर
A deficiency of haemoglobin in the human body directly results in anaemia, which significantly reduces the blood’s oxygen-carrying capacity. Because haemoglobin is the vital iron-rich protein in red blood cells responsible for binding and transporting oxygen from the lungs to all body tissues, its shortage starves the cells of the oxygen required for cellular respiration and energy production.

When a person breathes in air, the air enters into his body through an organ A having two holes B in it. The air then passes through pharynx and larynx and enters into a tube C. The tube C divides into two smaller tubes D at its lower end. The two smaller tubes are attached to two respiratory organs E. Each smaller tube divides inside the organs E to form a large number of still smaller tubes called F. The smallest tubes F have air-sacs G at their ends in which gaseous exchange takes place in the body of the person. What are A, B, C, D, E, F and G?
| There is a pair of bean-shaped organs P in the human body towards the back, just above the waist. A waste product Q formed by the decomposition of unused proteins in the liver is brought into organ P through blood by an artery R. The numerous tiny filters S present in organ P clean the dirty blood by removing the waste product Q. The clean blood goes into circulation through a vein T. The waste substance Q, other waste salts, and excess water form a yellowish liquid U which goes from organ P into a bag-like structure V through two tubes W. This liquid is then thrown out of the body through a tube X. |
