What is the major artery serving the arm

Microscopic Structure of the Blood Vessels l views of an artery and of a vein are shown here Identily each, on the lines to the sides, note the structural details that enabled you to make these identifications (vessel type) (vessel type) Now descibe each tunic more fully by selecting ts characteristics from the key below and placing the approprate key lettes on the answer lines Tunica intima Tunica media Tunica externa Key: a innermost tunic b. most superficial tunic regulates blood vessel diameter contains smooth muscle and elastin f. has a smooth surface to decrease resistance to blood flow d. e. c. thin tunic of capillaries 2. Describe the role that valves play in returning blood to the heart 3. Name two events occurring within the body that aid in venous return. and 4. Considering their functional differences, why do you think the wals of arteries are proportionately thicker than those of the corresponding veins?

Trace the pathway of a carbon dioxide gas molecule in the blood from the inferior vena cava until it leaus Name all structures (vessels, heart chambers, and others) passed through en route 12. Most arteries of the adult body carry oxygen-rich blood, and the veins carry oxygen-poor blood How does this differ in the pulmonary arteries and veins? 13. How do the arteries of the pulmonary circulation differ structurally from the systemic arteries? What condtion is indicated Dy this anatomical difference? Fetal Circulation function in the fetus; then, note its fate (what happens to it or what it s 14. For each of the following structures, first indicate its converted to after birth). Circle the blood vessel that carries the most oxygen-rich blood. Fate and postnatal structure Function in fetus Structure Umbilical artery Umbilical vein Ductus venosus Ductus arteriosus Foramen ovale

Why is this blood carried to the liver before it enters the systemic circulation? 17. The hepatic portal vein is formed by the union of the and the Thev vein carries blood from the The vein drains the and The __ vein empties into the splenic vein and drains the and 18. Trace the flow of a drop of blood from the small intestine to the right atrium of the heart, noting all structures encountered or passed through on the way 19. +A peripherally inserted central catheter (PICC) line involves the use of a long, thin tube to deliver medications or nutrients to a patient. For adult patients, it is usually inserted into the right cephalic vein. Trace the route that a medication would take to reach the right atrium. List all vessels on the route 20. +A patient with iliofemoral deep vein thrombosis (FDVT) has a blood clot located in the femoral or external liać vein, Such a patient is at risk of the clot traveling to the lungs, resulting in a pulmonary embolism. Trace the route of the clot from the femoral vein to the pulmonary artery. List all vessels on the route.
