The human body is made up of organs, bones, muscles, tissues, skin and blood vessels. The body's network of blood vessels, which carries blood to and from cells, is called the blood vascular system.

The blood is constantly being circulated in the body through arteries and veins. Oxygen rich blood is pumped out of the heart and is carried by the arteries to all parts of the body. In the cells and tissues of various organs, the arteries break down into smaller and smaller vessels called capillaries. As the blood moves through the capillaries the oxygen and nutrients move out in to the cells to nourish them and the waste matter and the carbon dioxide moves in. The blood after leaving the capillaries enters the veins which become larger and larger to carry blood back to the heart. Exchange of the metabolites and oxygen is possible because the flow of blood becomes very slow and the walls of the capillaries are sufficiently thin.

The vascular system works hand in hand with other body systems. As the blood moves through the lungs, exchange of carbon dioxide and oxygen takes place. In the digestive system the nutrients are absorbed in the blood and then delivered to body tissues. The waste matter collected from various tissues is filtered out when it flows through the kidneys, and it is excreted out of our body as urine.

The vascular system is thus the circulatory system of the body.

Blood Vascular system consists of Blood and Lymphatic vascular system. This system is specialized connective tissue.

The blood is basically used for transportation of oxygen, nutrients and hormones to the tissues and for collection of waste products.

On the other hand, the cardiovascular system consists of the heart, pulmonary circulation and systemic circulation.

The blood vascular system and the lymphatic vascular system are the two divisions of the circulartory system there for the blood vascular system does not consist of the blood and lymphatic vascular systems.

The vertebrate blood system consists of a series of tubes called blood vessels through which the fluid is kept circulating by a muscular pumping organ, the heart. The system is closed, while of that of some lower animals like cockroach where blood circulates through irregularly shaped open species. This arrangement in insects and other arthropods is an open blood system.

There are three kinds of blood vessels. Arteries, veins and capillaries. Blood is pumped from the heart into arteries, which divide into arterial capillaries, connecting with veinous capillaries which join up to form vein returning to the heart.

Capillaries are in intimate contact with cells and from which excretory products are received. Organs required most food and oxygen are most richly supplied with capillaries. Arteries have strong thick walls and blood flow in them with relatively high pressure and they carry no valves.

Veins have thin walls and there is an even flow of blood under low blood pressure and they contain valves to prevent back flood of blood.

Both organs to transport the blood to heart function in harmony and any dysfunctional activity can cause certain blood related issues in bodies, therefore, it is necessary that blood flows smoothly through these organs to create a perfect blood vascular system.
