Figure 40.10 Which of the following statements about the circulatory system is false? Blood in the pulmonary vein is deoxygenated. Blood in the inferior vena cava is deoxygenated. Blood in the pulmonary artery is deoxygenated. Blood in the aorta is oxygenated.
Rearrange these structures in the order in which blood passes through them; assume that the blood is about to leave the right atrium. Aorta Aortic semilunar valve Left ventricle Left atrium Lung capillaries Mitral valve Pulmonary semilunar valve Pulmonary arteries Right ventricle Superior/Inferior vena cava Tissues of the body Tricuspid valve Pulmonary trunk Pulmonary veins
Put in Order (rearrange these structures in the order in which blood passes through them; assume that the blood is about to leave the right atrium) aorta aortic semilunar valve left ventricle left atrium lung capillaries mitral valve pulmonary semilunar valve pulmonary arteries right ventricle superior/inferior vena cava tissues of the body tricuspid valve pulmonary trunk pulmonary veins
Which of the following statements best describes the function of the pulmonary arteries or veins? Pulmonary arteries carry deoxygenated blood from the right ventricle of the heart to the lungs. Pulmonary arteries carry deoxygenated blood to the right atrium of the heart from the lungs. Pulmonary veins carry deoxygenated blood from the lungs to the left atrium of the heart. Pulmonary veins carry oxygenated blood from the lungs to the right atrium of the heart.
Which of the following statements best describes systolic blood pressure? Systolic blood pressure depends upon the force of the heart contractions - the stronger the contractions the higher the systolic pressure will be. Systolic blood pressure depends on how tightly the cuff of the sphygmomanometer is tightened. Systolic blood pressure depends upon the resistance of the blood vessels - the greater the resistance to blood flow the higher the systolic pressure will be. Systolic blood pressure depends upon the force and frequency of the heart contractions - the stronger and more frequent the contractions the higher the systolic pressure will be.
Which statement concerning the pulmonary vein is correct? It carries oxygenated blood from the lung to the left ventricle of the heart It carries deoxygenated blood from the right ventricle of the heart to the lung It carries deoxygenated blood from the right atrium of the heart to the lung It carries oxygenated blood from the lung to the left atrium of the heart None of the above
for its oxygen then it may die, forming rct. The severity of this condition depends on the precise location of the occlusion, which downstream tissues are involved, and how large an area of tissue dies. Use Figure 4.9 as a reference and list the flow of blood through both circuits in order, beginnng with the right atrium (don't forget to include the heart valves). 1. If an embolus breaks off in a systemic vein in the leg, it would be able to pass through: It would occlude: 2. If an embolus formed in the left ventricle, it would be able to pass through: 3. It would occlude: 4.
A 56-year-old man is admitted to the coronary care unit (CCU) for an acute inferior wall myocardial infarction. The cardiologist is trying to optimize the oxygen delivery to the myocardial tissue. Supplemental oxygen is provided by the nasal cannula at 3 L/min. which of the following best describes the oxygen- carrying capacity of whole blood? it is only related to respitaroy exchange ratioit is only the amount of O2 dissolved in the blooddependent on the alveolar PO2 onlyit is the sum of the dissolved O2 plus the amount of O2 bound to hemoglobin it is only equal to Oxygen attached with Hb
Which of the following are true of the pericardium? There is a small amount of fluid found deep to the visceral layer. The fibrous outer layer can also be called the parietal layer. ● In addition to a fibrous layer, the pericardium has a visceral and parietal lay Provides electrical insulation between the atria and ventricles Separates the left and right ventricles.
Which of the following statements about the circulatory system is INCORRECT? Question 25 options: With respect to diameter: Aorta > arteries > arterioles > capillaries Arterial walls are thicker than the walls of veins of the same size Arteries retain their round shape when empty, veins are thin and tend to collapse Veins always carry de-oxygenated blood away from capillary beds Blood pressure in veins is lower than in arteries of the same size
Which of the following contains blood with the lowest oxygen content? a. aortab. left atriumc. right ventricled. pulmonary veinse. systemic arterioles
