Laboratory Review 14 with tiss 1. What blood vessels to is connect arterioles to venules and exchange m fluid? 2. Which blood vessels retum blood to the right atrium? 3. Does the pulmonary artery carry blood back to or away from the heart 4. Is the blood entering the left ventricle O,-poor or 5. What valve prevents the backfows of blood when the left 6. Which circuit delivers blood to the spleen, the relaxes? pulmonary or the systemic : What vessel transports blood to the liver from the digestive tracr? 8. Do pulmonary veins carry O,-poor or O,rich blood? 9. In addition to the esophagus and the posterior re passes through vena cava, what structu the diaphragm? 10. What is the 11. What organs are served by the anterior mesenteric artery? 12. What arteries form from the branching of the posterior end of the aorta? 13. What is the name of the vein that is joined to the posterior vena cava by name of the veins that serve the neck and head regions of the body? the venous duct (ductus venosus)? (Hint it was cut when the abdominal cavity was exposed.) 14. Which type of blood vessel (artery or vein) has a thick wall with a lot of smooth muscle that helps regulate blood pressure? Thought Questions 15. Explain why narrowing or blockages of the coronary arteries can be life threatening, and identify which arteries, when blocked, increase the risk of having a stroke. 16. Explain why an airline recently introduced an exercise video to combat deep vein thrombosis (clots that form in deep veins after prolonged inactivity), Consde the presurebod n veins and venous structure in your reply. ing arteries and veins, arteries usually appear red and veins usually appear blue. Explain why es seen in Figure 14.2 appear blue and the pulmonary veins in Figure 14.2 appear red. the pulmonary SystemExplanation / Answer
1.) Capillary
2.) Superior vena cava, inferior vena cava and coronary sinus
3.) Pulmonary artery carries blood from right ventricle of heart to the lungslfor oxygenation.
4.) Blood entering the left ventricle is oxygenated i. e., oxygen rich.
5.) Aortic and Pulmonary semilunar valves
6.) Systemic
7.) Hepatic portal vein
8.) Oxygen rich
9.) Descending aorta
10.) Subclavian, internal jugular, external jugular and anterior jugular vein
11.) Intestine and pancrease
12.) Brachiocephalic artery, the left common carotid artery and left subclavian artery.
13.) Umbilical vein
14.) Artery
15.) The blockage in the coronary arteries is called the 'hardening of the arteries'. These deposits cause the heart to receive less blood and oxygen by slowly narrowing the coronary arteries. This decrease in blood flow may cause chest pain, shortness of breath or other symptoms. A complete blockage can cause heart attack.
The coronary artery when blocked causes the risk of having a stroke.
16.) The airline recently introduced an exercise video to combat deep vein thrombosis. This is done so as to prevent the passengers from prolonged inactivity. Deep vein thrombosis creates a real risk of blockage in the blood vessels of the lungs.
17.) In figures, the arteries are shown in red while the veins in blue so as to distinguish the oxygenated and deoxygenated blood. The oxygenated blood is shown in red and the deoxygenated one in blue.
In general, the arteries carry oxygenated blood except pulmonary artery which carries deoxygenated blood and thus shown in blue, and veins carry deoxygenated blood except pulmonary vein which carries oxygenated blood and so is shown in red color in figures.
