Rad corpuscles of human blood stream are...

Rad corpuscles of human blood stream are known to be flattened discs. Blood count shows `RBC_s` of sdhte order of `5xx10^6` 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?

Text Solution

Verified by Experts

The correct Answer is:
`10^(13)`
Number of `RBC_s in 1mm^3 = 5xx10^6`
Total volume fo blood = 5 litres
`5xx10^3xx10^3 mm^3`
Total number of `RBC_s = 5xx10^6xx5xx10^6`
`2.5xx10^(13) ~~10^(13)`

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)
