Hint: Under the microscope, the lumen and the entire tunica intima of a vein appeared smooth whereas those of an artery will normally appear wavy because of the partial construction of smooth muscle in tunica media the next layer of blood vessel walls.
Complete answer:
In this question we have been asked to draw a well labelled diagram of TS of arteries and TS of vein. So, first of all, what does TS mean? T.S. is short for transverse section. It is a cross section obtained by slicing the body or any part of the body structure in a horizontal plane. This is a plane that intersects the longitudinal axis at the right angle. Blood is carried to the body why blood vessels and arteries are blood vessels that carry blood away from the heart while veins return blood to the heart. Arterial wall is thicker than veins because they are closer to the heart and receive blood that is surging at a far greater pressure. Arteries and veins both have lumen. Lumen means a hollow passageway through which blood flows. Arteries have smaller lumen than veins, a characteristic that help to maintain the pressure of blood moving from the system. The thicker walls of arteries and smaller diameter give arterial lumen more rounded appearance in cross-section than lumen of veins. The arteries and veins have three layers The middle layer is thicker in arteries and it is in the veins. The innermost layer is tunica intima which is the thinnest layer, the middle layer is tunica media which is the thickest layer and the outermost layer is tunica adventitia which is the thickest layer in veins.
Note: Arteries located deep within the body and are red in color while veins are peripherally located closer to skin and are blue in color.
