No, the arterioles are very small vessels and lack this thick layer. Instead they consist only of an endothelial layer wrapped by a few smooth muscle fibres.
the middle layer, called the tunica media
Yes. The arteriole has different layers of tissue from inside to out: endothelial layer, basement membrane, smooth muscle and then the extra cellular matrix. The basement membrane is composed of collagen and fibrillin.
Ans: Different arteriole the different arteriole carries blood from the branch of the renal artery into the glomerulus, the different arteriole carries blood away from the glomerulus and back into the branch of the anal vein.
Elastic Cartilage is found on the external ears and larynx.
The outermost layer is known as the tunica externaformerly known as "tunica adventitia" and is composed ofconnective tissue. Inside this layer is thetunica media, ormedia, which is made up ofsmooth musclecells and elastic tissue. The innermost layer, which is in direct contact with the flow of blood is thetunica intima, commonly called theintima. This layer is made up of mainlyendothelial cells. The hollow internal cavity in which the blood flows is called thelumen.
Upper layer of arteries is made up connective tissues,middle layer of elastic tissues and inner layer of endothelium vein have the same composition but it is relatively less elastic then the arteries.
what is the actual size of arteriole
The reticular layer of the dermis
Veins and capillaries do not have an outer layer of elastic tissue. While arteries possess an elastic layer to help accommodate the high pressure of blood flow, veins have a thinner wall and rely on surrounding tissues and valves to assist with blood return to the heart. Capillaries, being the smallest blood vessels, consist only of a single layer of endothelial cells, lacking any elastic or muscular layers.
Efferent arteriole takes the blood away from the glomerulus
Reticular layer
Arteries actually have 5 layers, it is the veins that have 3. Arteries have: -the Outer coat -Elastic layer -Middle coat (thin) -Another elastic layer -Endothelium
