Vedclass · Answer

(D) In human blood,the count of blood platelets is approximately $1.5$ to $3.5$ lakhs per cubic mm,whereas the count of $WBCs$ is approximately $6000$ to $8000$ per cubic mm. Therefore,the blood has significantly more platelets than $WBCs$.Veins and arteries are both types of blood vessels. Arteries carry blood away from the heart,while veins return blood to the heart. At any given time,the volume of blood in the venous system is generally higher than in the arterial system.Blood consists of two main parts: Plasma,which constitutes about $55-60\%$ of the total blood volume,and the formed elements (cells),which constitute about $40-45\%$ of the total blood volume.$WBCs$ are primarily produced in the red bone marrow,though some types are also produced in lymph nodes,the spleen,and the thymus.
