Rad corpuscles of human blood stream are known to be flattened discs. Blood count shows `RBC_s` of sdhte order of `5X10^6` in each cubic millimeter of blood. If the adult body contains 5 litres of blood, what is the order of total number of red corpuscles it contains?

Ravi, who lived at sea level, had around 5 million RBC per cubic millimeter of his blood. Later when he lived at an altitude of 18,000 ft, showed around 8 million RBC per cubic millimeter of blood. This is an adaptation because

A small quantity of solution containing Na^24 radio nuclide (half-life=15 h) of activity 1.0 microcurie is injected into the blood of a person. A sample of the blood of volume 1cm^3 taken after 5h shows an activity of 296 disintegrations per minute. Determine the total volume of the blood in the body of the person. Assume that the radioactive solution mixes uniformly in the blood of person. (1 curie =3.7 xx 10^10 disintegrations per second)

A small quantity of solution containing Na^(24) radio nuclide (half-life 15 hours) of activity 1.0 microcurie is injected into the blood of a person. A sample of the blood of volume 1 cm^(2) taken after 5 hours shows an activity of 296 disintegrations per minute. Determine the total volume of blood in the body of the person. (1 curie =3.7xx10^(10) disintegrations per second.)

The organs A of a person have been damaged completely due to which too much of a poisonous waste material B has started accumulating in his blood, making it dirty. In order to save this person's life, the blood from an artery in the person's arm is made to flow into long tubes made of substance E which are kept in coiled form in a tank containing solution F. This solution contains three materials G, H and I in similar proportions to those in normal blood. As the person's blood passes through long tubes of substance E, most of the wastes present in it go into solution. The clean blood is then put back into a vein in the arm of the person for circulation (a) What are organs A ? (b) Name the waste substance B (c) What are (i) E, and (ii) F ? (d) Name G, H and I (e) What is the process described above known as ?

A small quantity of solution containing Ne^(24) radio nucliode (half life = 15 hour ) of activity 1.0 microcurlar is injected into the blood of a person A sample of the blood of volume 1 cm^(3) taken a after 5 hour shown an activity of the blood in the body of the person . Assume that redicative solution mixed uniformly in the blood of the person (1 curie = 3.7 xx 10^(10) disntegrations per sound)
