Blood Vessels Things to be good at: 1. Compare and contrast the structures and functions of types of blood vessels (from arteries to veins) 2. Identify and describe the major vessels of the pulmonary circuit 3. Identify and describe the pathways and functions of the major arteries and veins of the systemic circuit 4. Trace a drop of blood through the systemic arteries and veins of the body Which is true? A. Veins carry deoxygenated blood B. Veins carry blood toward the heart C. Venous blood is blue Vessel Tissues Arteries have more tunica ____________ , veins have more tunica ____________ Vessel Names Rank from earliest to latest in the circuit: • Postcapillary venule • Arteriole • Muscular artery • Thoroughfare channel • Elastic artery • Vein • True capillary • Venule • Metarteriole 1. If the capillary bed is not needed, what vessel is left out? 2. Give an example of when a capillary bed is not needed Pulmonary Circuit Make sure you know the blood flow through the right side of the circulatory system. Ascending aorta Aortic arch Pulmonary veins Subclavian arteries Common carotids Descending aorta Common iliac arteries Not drawn to scale Not all vessels are listed Internal carotids External carotids Mesenteric arteries Celiac trunk Renal arteries Orbits and most of cerebrum External regions of head and brain Upper limbs Intestines Internal jugular vein External jugular vein Subclavian vein Hepatic portal vein Hepatic veins Pulmonary arteries Brachiocephalic vein Superior vena cava Inferior vena cava Renal veins Internal iliac arteries External iliac arteries Liver Kidneys Pelvis Lower limbs Internal iliac vein External iliac vein Common iliac vein The aortic arch A drop of blood was just in the left subclavian artery. Where did it come from and where might it go? A. Aortic arch, axillary artery B. Brachiocephalic trunk, axillary artery C. Aortic arch, common carotid artery D. Brachiocephalic trunk, common carotid artery Deep vs Superficial Veins Describe two different ways blood might return from the fingertip to the heart, using a deep vs superficial path. Hepatic Portal System How is the hepatic portal system different than most organ bloodflow? Arterial blood Venous blood Stomach and intestine Liver Nutrients and toxins absorbed Inferior vena cava Liver cells (hepatocytes) Nutrients and toxins leave Hepatic portal vein Hepatic vein Second capillary bed (liver sinusoids) First capillary bed Hepatic portal system Schematic of the hepatic portal system Hepatic Portal System Which best describes blood flow at the liver? A. Hepatic veins drain the liver and celiac trunk provides liver with venous blood B. The hepatic portal vein drains the liver and the hepatic veins supply the liver with venous blood C. The hepatic portal vein supplies the liver with venous blood and the hepatic veins drain the liver D. The hepatic veins supply the liver with venous blood and the celiac trunk supplies the liver with arterial blood Friday’s lecture – Kahoot of blood vessels Lymphatic system
