${\purple{\underline{\underline{\large{\mathtt{Answer:}}}}}}$

Blood:

• Blood is a liquid connective tissue.
• It consists of blood plasma and blood corpuscles.
• Blood corpuscles are of three types:

1. Red Blood Corpuscles (RBC)
2. White Blood Corpuscles (WBC)
3. Blood Platelets

Red Blood Corpuscles:

• These are biconcave disc-like structures and their cytoplasm is filled with haemoglobin.
• RBC's are manufactured in bone marrow.
• Their life span is about 120 days.
• After that they are destroyed by liver and spleen.
• Their small size helps in absorbing oxygen and enables them to travel in blood capillaries.

White Blood Corpuscles:

• These are nucleated and amoeboid cells that lack haemoglobin.
• These are of two types: granulocytes and agranulocytes.
• They are manufactured in bone marrow.
• They are capable of squeezing out capillaries that destroy foreign matter.
• They are known as the soldiers of the body.
