Tunica Intima
blood cells
The tunica interna of a blood vessel is a single layer of endothelium with a basal lamina.Connective tissue
If stratified squamous epithelium lined the blood vessels, gas and nutrient exchange across the vessel walls would become much more complex, requiring multiple transports and making the process much more energy intensive.
thin wall - rapid diffusion small gaps - allow diffusion and actv tspt goblet cells in lung epithelium - secrete mucus to trap bacteria ciliated epithelium - waft mucus out of the lungs squamous - stretch and recoil around a blood vessel there are about another 10 types of specialised epithelium tissues and cells in the human body
The innermost layer of epithelial cells of a blood vessel is called endothelium.
Connective tissue obtains nutrients through diffusion from nearby blood vessels. Nutrients diffuse through the blood vessel walls and into the surrounding connective tissue to provide nourishment to the cells within the tissue.
connectiveThe outer layer of a blood vessel (artery or vein) is called the tunica externa or tunica adventitia.See http://training.seer.cancer.gov/module_anatomy/unit7_3_cardvasc_blood1_classification.htmlpericardium is the layer of the blood vessel that is made of tough connective tissue.
The tunic intima is the innermost layer of a blood vessel. It has a slic surface that minimizes friction, allowing blood to move through the lumen.

The outer layer of blood vessels is composed of connective tissue called the tunica externa or adventitia. This layer provides structural support and protection to the blood vessel. It also helps to anchor the vessel in place within surrounding tissues.
The smooth dense irregular connective tissue that is continuous with the outer coat of the ureter is known as the adventitia. It provides structural support and anchors the vessel in place, allowing for movement and flexibility.
The surface of the umbilical cord is comprised of amniotic epithelium contiguous with the placenta and fetus. The connective tissue of the umbilical cord is of extraembryonic mesoderm origin, composed of Wharton's jelly (mucoid connective tissue) and sparsely distributed cells, including, stromal mesenchymal cells, contractile cells, macrophages, mast cells and myofibroblasts. It also contains a large quantity of water which aids in the prevention of umbilical blood vessel compression. There are umbilical arteries (2) and a vein inside the mucoid tissue.
