Blood vessels are a complex network of hollow tubes that carry blood throughout the body. The work of the arteries is essential for the body because the blood transports valuable nutrients and removes waste products from our cells. Blood vessels are made up of layers of connective tissue and muscle. The inner layer of a blood vessel is made up of endothelium (a layer of thin, smooth cells). In capillaries and sinusoids, the endothelium forms most of these vessels. The blood vessel endothelium is similar to the lining of the internal tissues of organs such as the brain, lungs, skin, and heart. At the heart of this inner layer is called the endocardium. Types of blood vessels Arteries Arteries are elastic vessels that carry blood from the heart. The pulmonary arteries carry blood from the heart to the lungs. The lung is where oxygen is taken up by red blood cells. The systemic arteries carry blood to the rest of the body. Veins Veins are elastic vessels that carry blood to the heart. Veins can be divided into four main types, which are: pulmonary, systemic, superficial and deep veins. Capillaries Capillaries are very small vessels inside the body's tissues that carry blood from the arteries to the veins. Fluid exchange between capillaries and body tissues takes place in the capillary bed. Sinusoids Sinusoids are very small vessels inside the liver, spleen, and bone marrow. blood circulation Blood circulates throughout the body through the cardiovascular system. This system consists of the heart and the circulatory system. Blood vessels carry blood from the heart to all parts of the body. Blood travels from the heart through the arteries (small arteries), then to the capillaries or sinusoids, and then to the veins (very small veins) and veins, and finally back to the heart. Microfluidic exchanges with blood flow from the arteries to the capillaries or sinusoids to the veins. As blood moves through the capillaries, substances such as oxygen, carbon dioxide, nutrients and waste products are exchanged between the blood and the fluid that surrounds the cell.
