Question

Describe the composition and functions of blood.​

Answer 1

Answer:​
$\underset{–}{\text{Composition of Blood}}$:​
Blood is a fluid connective tissue. In this tissue, cells or corpuscles move in a fluid matrix called blood plasma. ​

Plasma:​

• Plasma forms 55 percent of the total volume of blood. It is a complex fluid and contains inorganic salts and organic compounds. ​
• Organic substances of plasma are soluble proteins such as albumins, globulins, fibrinogen, and many more. ​

Corpuscles: ​
The remaining 45% of the blood volume is made up of corpuscles. The different types of blood corpuscles are as follows:​

• Red Blood Cells​
• White Blood Cells​

1. $\underset{–}{\text{Granulocytes}}$- Neutrophil, basophil. eosinophil​
2. $\underset{–}{\text{Agranulocytes}}$- Monocytes​

• Platelets​

Functions of Blood:​

• Blood transports nutrients, hormones, and vitamins to the tissues and transports excretory products from the tissues to the liver and kidney.​
• The red blood corpuscles (RBCs) carry oxygen to the tissues for the oxidation of foodstuff.​
• The white blood cells (WBCs) fight disease either by engulfing and destroying foreign bodies or by producing antitoxins and antibodies that neutralise the harmful harmful effects of germs.​
• Blood platelets disintegrate at the site of injury and help in the clotting of blood.
