1-4

1) The inner most tunic of the blood vessel consists of_ whereas the middle tunic consists of _ 1 Point Smooth muscle, epithelium Skeletal muscle, epithelium Epithelium, smooth muscle Epithelium, skeletal muscle 2) The thickest vessel walls are found in the_whereas the most porous (leaky) vessel are the 1 Point Capillaries, veins Veins, capillaries Capillaries, arteries Arteries, capillaries 3) Capillaries vary with regard to their permeability which allows for improved filtration of the blood. In which organ would you find the most permeable type of capillary? (Think about which organ would need to filter blood) 1 Point Heart Skeletal muscle Liver Stomach 4) The first artery(ies) to branch off of the aorta after leaving the heart would be the 1 Point Brachiocephalic artery Left common carotid artery Left subclavian artery Left and right coronary arteries

Answer 1

of - I consist middle tunic - The inner most tunic of blood vessel consist I whereas the middle tunic consits of Ang Epithelium , smooth muscle tunic of blood vessel - consists of epitheli whereas Tunica - Consists of externa - Como smooth muscle of 2) The fibrous connective tissue 2) The consists thicked in thickest vessel walls are found in the whereas the most porous (leaky) vessels are the — Ang Arteníes, Capillasies *Arteries → are the thickest vessel wall come ce ny → Capillaries are the most porous Cleaky) vessels, which connects the arterioles and venules. 3) Capillasies vary with regard to their permeability which allows for improved infiltration of blood. In which Orqan wound you to the most permeable type of capillary? Ans Liver explanation - sinusoids are present in the liver. + Sinusoids are one of type of capillaries, which contains bía holes in endothelial membranes , So sinusoids are most permeable.. 4) The first artesy (lies) to branch off of the aorta after leaving the heart would be lins Brachiocephalic artery + Branchiocephalíc - jst branch of aorta 4 Branchiocephalic again dividos into right common carotid artery and right subclavian astery. common carotid artery - and branch of aorta + left subclavian artesy - 3r8 branch of aosto 1 Hod.
