This is the liquid substance that makes up 55% of our blood (90% water).

• Plasma

• Leukocyte

• Platelets

• Erythrocyte

This component of our blood helps fight infection and disease in our body.

• Plasma

• Leucocytes

• Platelets

• Erythrocytes

These are cell fragments that help form clots to stop bleeding.

• Plasma

• Leucocytes

• Platelets

• Erythrocytes

These help transport oxygen and contain hemoglobin.

• Plasma

• Leucocytes

• Platelets

• Erythrocytes

If you have this blood type, you are considered as a "universal donor."

• O

• A

• B

• AB

All of the following are functions of blood except:

• Transportation of oxygen and carbon dioxide.

• Blood clotting when there is an injury

• Synthesis of vitamins.

• Defense against infection.

What are the main components of blood?

• Plasma, buffy coat and erythrocytes

• Platelet and hormones

• Plasma and plasma protein

• Plasma, oxygen and carbon dioxide
