Question #ded6d

Answer 1

Red blood cells`(45%)`, white blood cells`(1%)` and platelets`("present per microliter of blood")`.

Explanation:

Red Blood Cells:
The cytoplasm of a red blood cell contain:

• Haemoglobin `to` `95%`(for dry weight) and about `35%`(if water is counted).

• Enzymes, salts and other proteins `to` `5%`

White Blood Cells or erthyrocytes:
WBCs don't contain any pigment.These are much larger in size than red blood cells. They are grouped into
`color(blue)("granulocytes i.e neutrophils, eosinophils and basophils")` and `color(green)(" agranulocytes i.e monocytes and lymhphocytes".`

• Monocytes and neutrophils `to` kill the invader microbes by damaging or digesting them by phagocytosis.

• Basophils `to` produce heparin and histamine. Heparin inhibits clotting of blood. Histamine participates in allergic reactions.

• Lymphocytes `to` provide immunity against disease.

• Eosinophils `to` Inactivate inflammation producing subsances and attack parasites.

Platelets:
Platelets also don't contain any pigment.

• Platelets don't have nucleus thus can't fit in the definition of cells.

• These are fragments of large cells called megakaryocytes.

• Platelets prevent bleeding by making blood clot at the site of injury.
  These convert the soluble fibrinogen into insoluble fibrin . The fibrin protein enmesh the red blood cells and other platelets in the area of damaged tissue and ultimately forms clot which act as a temporary seal to prevent bleeding.
