Cross Section Of Artery
The venous system is a lower pressure system containing veins that have larger lumens and thinner walls.
Cross section of artery. Cross section heart cross section nerve cross section pf vein and artery cross section pf vein and artery diagram cross section pf vein and artery picture human. Found near every living cell of the body. Cross section of artery and vein.
Thick tunica media is composed of canoe shaped smooth muscle cells. Orienting yourself within such a cross section is easy. Lining the core of each is a thin layer of endothelium and covering each is a sheath of connective tissue but an artery has thick intermediate layers of elastic and muscular fiber while in the vein these are much thinner and less developed.
Cross section through the thalamus. X50 tunica media tunica adventitia lumen tunica intima. These arteries that receive blood directly from the heart the aorta and the pulmonary artery.
Cross section through a vein capillaries. The star of the show brain is easily recognizable because it appears highly convoluted full of ridges gyri and indentations sulci the paired thalami appear as two circular masses in the midline forming the walls of the third ventricle the neurocranium appears as a meshwork trabecular. The arterial system is a relatively high pressure system so arteries have thick walls that appear round in cross section.
They often appear flattened. Take a look at this cross section through an elastic artery and identify the three main layers tunica intima tunica media and tunica adventitia.
