Functions of Blood:
1. Transportation:
- Blood carries oxygen from the lungs to the body's tissues.
- It transports nutrients from the digestive system to the cells.
- Hormones produced by various glands are also transported through the blood to their target organs.
2. Regulation:
- Blood helps regulate body temperature by absorbing and distributing heat throughout the body.
- It plays a role in maintaining pH balance, ensuring that the body's internal environment stays within the optimal range.
- Blood also helps regulate fluid balance by transporting water and electrolytes to different parts of the body.
3. Protection and Defense:
- The blood contains white blood cells that defend the body against foreign invaders such as bacteria, viruses, and other pathogens.
- It also contains antibodies and other immune system components that help in neutralizing and destroying harmful substances.
- Blood clotting is another vital defense mechanism that prevents excessive bleeding when a blood vessel is damaged.
4. Waste Removal:
- Blood carries metabolic waste products, such as carbon dioxide and urea, from the cells to the organs responsible for elimination, like the lungs and kidneys.
In conclusion, blood performs multiple essential functions in the body, including transportation of oxygen, nutrients, and hormones, regulation of body temperature and fluid balance, protection against infections, and removal of waste products.
