5. the number of red blood cells per cubic millimetre of blood is approximately 5.5 million. if the average body contains 5 litres of blood, what is the total number of red blood cells in the body ? ( 1 liter = 100000 mm³.
Answers
Answer:
The average body contains 5 L of blood.
Also, the number of red blood cells per cubic millimetre of blood is approximately 5.5 million Blood contained in body=5 L=5×100000 mm³ Red blood cells = 5.5x 1000000 mm³
Blood = 5.5x 1000000 x5 x 100000
=55x5×10¹0
= 275 x 10¹0. = 2.75 x 10¹²
Answer:
The complete blood count (CBC) is a blood test used to screen your overall health and to look for many different illnesses, including anemia, infections, and leukemia. The test extracts a large amount of information from the blood sample you've given, including:
