The body parts and functions are explained in 2 branches of science: anatomy and physiology. The Cardiovascular system plays a crucial role when it comes to the working of our body.

It is this system that makes sure the smooth running of each activity that occurs in our body. The system is made of the heart, blood, blood vessels and the lymphatic system. Its big part is to pump blood around the body. It's a hollow muscular organ divided by a vertical wall called the septum. The two chambers are further split into the atrium above, and the ventricle below, leading to 4 chambers. Oxygenated blood is carried away from the heart by the arteries whilst deoxygenated blood is brought back to the heart by the veins. The heart acts as the central power point as it is the part that propels blood to all the other parts of the body and this indicates that failure of the heart to pump blood would lead to malfunctioning of all the body cells and tissues.

The interstitial liquid that surrounds the tissue cells is serviced by blood which transports oxygen and nutrients to it whilst the lymph removes toxins and waste products. Blood forms about 70% of the body weight consisting of plasma, corpuscles and platelets. CO2 from the cells to the lungs. Hormone from the endocrine glands to the cells. As blood is the main transport system, so it might also bring bacteria to the tissues. The lymphatic system is the protective system that picks up the materials, cleans them of waste materials and poisons, and returns them to the blood.

Their big part is transport of blood to and from the heart. The heart system is thus the activator of each other activity that occurs in our body, since the body can't function without the flow of blood.

Here is a quick overview of the different functions of blood:

TRANSPORT

• Oxygen from the lungs to the cells.

• Carbon dioxide from the cells to the lungs.

• Nutrients from the intestines to the lungs.

• Waste materials from the cells.

• Hormone from the endocrine glands to the cells

• Heat from various cells

REGULATES

• pH(concentration of hydrogen ions)

• Body temperature.

• Salts.

• Water content in the cells.

PROTECTION

• Prevents loss by clotting and combats toxins

• Protects the body against heat loss.
