Tunica adventitia is poorly developed in arteries then in veins
The anatomical differences between a squid and an octopus are obvious.

Arteries carry blood from the heart to other parts of the body. Veins are much smaller vessels that are used to bring the blood back to the heart.
anatomic end arteries are vessels whose terminal branches donot anastomose with branches of arteries supplying adjacent areas . Functional end arteries are vessels whose terminal branches do anastomose with those of adjacent arteries , but the caliber of anastomoses is insufficient to keep the tissue alive should one of the arteries become occluded .
Of course they do. There are no anatomical or biochemical differences between Germans and any other nationalities.
Structurally, veins and arteries are very similar. The main differences is that veins move blood towards the heart, whereas arteries move blood away from the heart.
well here is one: Veins- oxygen-poor blood that is returning to the heart Arteries- oxygen-rich blood that is going to the cells
they both carry blood, differences: Veins- oxygen-poor blood that is returning to the heart Arteries- oxygen-rich blood that is going to the cells
The tunica media of arteries is larger than that of veins of same size.The tunica adventitia is larger in veins than arteries of same size.
Viens carry blood away from the heart while veins carry blood towardj the heart. Arteries are generally thicker than veins because arteries must withstand the pressure of the blood coming away from the heart.
Pulmonary Arteries lead from the heart to the lungs. Systemic arteries go everywhere else. Consequently, the pulmonary arteries are usually slightly smaller and thinner. There is also less of them.
