Understanding The Blood Vessels, Arteries, Capillaries, and Veins System
Blood vessels are hollow tubes like passage that convey blood and transfer it throughout your body. A network of arteries, arterioles, capillaries, venules, and veins make up the blood vessels. The major blood vessels in the system are;
- Arteries
- Veins
- Capillaries Arteries
Virus infection has the potential to result in irregular blood coagulation, “leaky” arteries, and decreased blood flow by resulting in endothelial damage.
Arteries
Arteries carry blood away from the heart. All arteries carry oxygenated blood, with the exception of pulmonary arteries that convey oxygenated blood in them.
Structure
Arteries are well adapted to their function. Following are the layers of arteries wall;
- The outermost layer (tunica adventitia) is made up of connective tissue.
- The middle layer (tunica media) is made up of smooth muscle and elastic tissue.
- The innermost layer (tunica intima) is made up of endothelial cells.
Arteries cover 10% to 15% of the body’s blood.

Capillaries of Blood Vessels
The smallest blood vessel that exist in the tissues are capillaries. The division of arterioles sets up these capillaries. However, the walls of capillaries comprise of single layer called endothelium. Capillaries transfer nutrients, oxygen, and waste products from the blood to the tissues.
Function
- Capillaries permit the exchange of materials between blood and tissues.
- It takes apart the waste products.
- It ensures that nutrients and gases from the blood diffuse to the cells.
Veins of Blood Vessels System
Vessels that transfer blood towards the heart. Veins are narrow, mainly fibrous tissue. All veins convey deoxygenated blood except pulmonary veins, which carry oxygenated blood. These are responsible for returning low-oxygen blood from the body to the heart for reoxygenation.
Function
- Veins take back blood to the heart with low pressure.
- Veins feature pressure-sensitive valves to prevent blood backflow.
