D170 W15 Blood Vessels and Lymph Williams Describe the properties of the three layers (tunics) of blood vessels Tunica intima – Tunica media – Tunica externa – Complete the following table about arteries and veins. For tissue make-up, describe what types of tissues that make up the vessel and the relative proportions of each. Vessel type Description Relative size Tissue make-up Location in body Elastic artery Muscular artery Arteriole Venule Vein Describe the general characteristics of capillaries and of capillary beds, noting the following structures: Metarteriole – Thoroughfare channel – Precapilalry sphincter – What are the differences between the three types of capillaries? Continuous – Fenestrated – D170 W15 Blood Vessels and Lymph Williams Sinusoid – How do molecules pass into and out of capillaries? Describe four ways. Describe what mechanisms are used to propel blood through arteries and veins. How are they similar, how are they different? What are vascular anastomoses? Provide examples of where you find them in the body. What are the functions of the pulmonary and systemic circuits? Describe the path of blood through the pulmonary circuit, noting the following structures: Pulmonary trunk – Right and left pulmonary arteries – Lobar arteries – Pulmonary veins – D170 W15 Blood Vessels and Lymph Williams Complete the following tables about the major systemic arteries and veins of the body. These are the only vessels that you will be held accountable for in this chapter (in addition to the coronary vessels from the Heart lesson). The aortic arch is completed for you. Being able to trace the flow of blood from the heart through these vessels is important! Artery Vessel(s) most immediately prior Vessel(s) most immediately after What general structures does it supply blood to? Ascending aorta Brachiocephalic trunk, left common carotid artery, left subclavian artery All of body Ascending aorta Aortic arch Descending aorta Brachiocephalic trunk Left common carotid artery Right common carotid artery External carotid arteries Internal carotid arteries Left subclavian artery Right subclavian artery Axillary artery Brachial artery Ulnar artery Radial artery Palmar arches Thoracic aorta Celiac trunk Superior mesenteric artery Inferior mesenteric artery Renal artery Gonadal artery Abdominal aorta Common iliac arteries Internal iliac arteries External iliac arteries Femoral artery Popliteal artery Anterior tibial artery Posterior tibial artery Arcuate artery D170 W15 Vein Superior vena cava Inferior vena cava Right and left brachiocephalic veins Internal jugular vein External jugular vein Dural venous sinuses Subclavian vein Axillary vein Cephalic vein Brachial vein Basilic vein Median cubital vein Ulnar vein Radial vein Dorsal venous network Hepatic veins Splenic vein Hepatic portal vein Renal vein Superior mesenteric vein Inferior mesenteric vein Common iliac vein Internal iliac vein External iliac vein Femoral vein Great saphenous vein Popliteal vein Posterior tibial vein Dorsal venous arch Blood Vessels and Lymph Williams Vessel(s) most immediately prior Vessel(s) most immediately after What general structures does it collect blood from? Brachial vein and basilic vein Subclavian vein Upper limb D170 W15 Blood Vessels and Lymph What is the hepatic portal system? Describe its contribution to digestion. Williams
