What kind of epithelium tissue lines the artery?
Simple squamus or endothelium
What are the three layers of an artery and state their function?
The three layers of an artery are Endothelium, smooth muscle, and connective tissue.
What is the medical term meaning pertaining to the lining of an artery?
the endothelium is the inner most linning of the artery vessel. Or better known as the Intima..... The tunica intima, the innermost layer, consists of an inner surface of smooth endothelium covered by a surface of elastic tissues
Which tunic contains the photoreceptors?
retina
How does tobacco use weaken blood vesseles?
Tobacco contains hundreds of compounds most of which are harmful. One of the main studied effects off tobacco smoking on arteries is that, once it is inhaled and enters the blood through the lungs, it disrupts the function of the lining of the arteries which is called the 'endothelium'. The endothelium has an important function in keeping the artery healthy. The disruptive effect of the smoke makes the artery more prone to developnig atherosclerosis - that is a furring of the arteries that eventually results in blockages causing heart attacks and strokes.
The structure of a capillary wall differs from that of vein or artery because?
it has a single tunic- only the tunica interna
What is the neural tunic?
The neural tunic, also known as the sensory tunic, is the deepest of the tunics in the eyeball. It's rods and cones allow for sight, and it contains neurons and ganglia.
Does an artery collapse when it's empty?
The endothelial lining of an artery cannot contract, so when an artery constricts, its endothelium is thrown into folds that give arterial sections a pleated appearance.Arteries are more resilient: When stretched, they keep their shape and elongate, and when released, they snap back.
What tissue makes up the blood vessel inner tunic?
The tunica interna of a blood vessel is a single layer of endothelium with a basal lamina.Connective tissue
Are all arteries lined with endothelium?
Yes. The only time that I can think of that there would be a break in an artery's endothelium is when a bit gets damaged, like with turbulent (disorganised) blood flow over an atheromatous (fatty) plaque that forms in the intima of the artery wall (there are many layers to an artery wall, the intima is one of them). Also, when a person gets a stent put in an artery to open up a narrowed bit (like when you have unstable angina) these stents can be "drug eluting" stents that stop the endothelium of the vessel from growing over the stent. Essentially, everything in the body that has a connection to the outside world (your skin, eyes, digestive tract, respiratory tract, urinary tract and reproductive tract) is lined with an epithelium. Everything inside the body that is hollow (blood vessels, lymph vessels, the heart's chambers, the ventricles in the brain) as well as the surface of most organs are lined with endothelium.
What is the only artery that contains blood that needs oxygen?
pulmunary artery
Which tunic of an artery is most responsible for maintaining blood pressure?
Tunica Media
