Neurovascular bundle fluid and blood, they tend to have large surface area and short diffusion path. Normally, capillaries consist of a central lumen lined with an endothelium, a single layer of smooth epithelial cells. In contrast, deep neurovascular bundles, with arteries in them, have a more complicated composition. Arteries are the vessels that transfer the blood pumped by the heart to the entire body. Arteries have high intraluminal blood pressure, relative to capillaries and veins. To compensate arteries have a smooth muscle and a connective tissue structure outside the endothelium. This composition allows arteries to contract/relax, be flexible under pressure, and transfer
Blood vessel diffuse vascular supply it is called an anastomosis. Anastomoses provide critical alternative routes for blood to flow in case of blockages. There is a layer of muscle surrounding the arteries and the veins which help contract and expand the vessels. This creates enough pressure for blood to be pumped around the body. Blood vessels are part of the circulatory system, together with the heart and the blood. The biggest difference in the structure of arteries and veins is the presence of valves. Backflow of blood is prevented in arteries by the heart. However in veins, one-direction valves are used to
