- The Greek anatomist Erasistratus, originally from Ceos, identified the correct function of the right atrioventricular valve of the human heart, which was to prevent backward flow of blood from: the right ventricle to the right atrium the right ventricle to the left ventricle the right ventricle to the left atrium the left ventricle to the right ventricle the left ventricle to the left atriumIn the given table, three of the anatomical and physiological terms are similar or related; one does not belong with the other three. Choose the term that does NOT belong in each of the following groups.

- The Greek anatomist Erasistratus, originally from Ceos, identified the correct function of the right atrioventricular valve of the human heart, which was to prevent backward flow of blood from: the right ventricle to the right atrium the right ventricle to the left ventricle the right ventricle to the left atrium the left ventricle to the right ventricleAs we auscultate the heart it is imperative, we understand what part of the heart we are listening to. Cellular senescence is observed when there is obstruction of the coronary circulation to the muscle tissue of the heart. If the left anterior descending artery (a.k.a. “Widow maker”) is occluded, predict an alternative route of blood flow to the myocardium. Start from the left coronary artery.below is a diagrammatic representation of the heart. Y Identify structure X. Explain the function of structure Y. Explain how the structure of the heart allows for the efficient pumping of blood around the body to deliver oxygen to, and collect carbon dioxide from, the body tissues. Describe three ways in which the structure of each of capillaries, veins and arteries are adapted to carry out their functions.
- Identify whether the following statement is either true or false. Left ventricle->Left atrium->Right ventricle->Right atrium is the correct sequence for blood entering the heart through the vena cavae and leaving through the aorta. The sinoatrial node is situated in the wall of the interventricular septum. Impulses through the conduction system of the heart follow the ordered path: SA node->conduction myofibers->AV bundle->AV node. To clearly hear the heart sound of the bicuspid valve, a stethoscope should be placed to the left of the sternum at the second intercostal space. At late diastole, the atria and ventricles are relaxed and the aortic semilunar valve is open. During ventricular contraction all the blood is forced out of the ventricles.Blood is pushed out of the heart through a large vessel, called the aorta. The aorta then divides into smaller and smaller blood vessels, eventually reaching vessels called capillaries. Capillaries are so small that oxygen and nutrients can diffuse across the vessel walls and into the tissues of the body, with CO2 and waste diffusing back into the blood. Let's say that the cross-sectional area of the aorta is 1 cm2 = 100 mm2. The blood pumps through the aorta at 100 mm/s but only through the capillaries at 1 mm/s. If each capillary has a cross-sectional area of 20 mm2, how many capillaries must there be in the body? Note: these numbers are not physiologically correct, but were chosen to make the math easier. The blood velocity through the aorta is closer to 300 mm/s. The capillaries have a total cross-sectional area of ~600,000 mm2 (6000 cm2), with a blood flow rate closer to 0.2 mm/s.Draw a block schematic of the heart showing the four main chambers and explain how oxygenated and de-oxygenated blood flows to the lungs and arteries. You should include a labelled diagram of a typical electrocardiogram (ECG) and indicate how the primary features of the ECG relate to the state of the heart as it varies over the cycle.
- Rearrange these structures in the order in which blood passes through them in a circuit from the heart to the foot and back. Put in order (start with the left ventricle). -abdominal aorta -anterior tibial artery -anterior tibial vein -aortic arch -ascending aorta -common iliac vein -common iliac artery -external iliac artery -external iliac vein -femoral artery -femoral vein -foot -inferior vena cava -popliteal artery -popliteal vein -right atrium -thoracic aorta -left ventricle‘The heart is adapted to ensure that blood flows in a controlled direction’ (as illustrated by the light purple and blue arrows positioned in Figure 2). Discuss this statement taking into account: • the stages of the cardiac cycle, • the electrical conductivity series, • the role of named valves.Identify whether the given statement is true or false -Left ventricle->Left atrium->Right ventricle->Right atrium is the correct sequence for blood entering the heart through the vena cavae and leaving through the aorta. -The sinoatrial node is situated in the wall of the interventricular septum. -Impulses through the conduction system of the heart follow the ordered path: SA node->conduction myofibers->AV bundle->AV node. -The heart is covered by the suprardium. -The “lub” sound of the heart is caused by closing of the semilunar valves. -To clearly hear the heart sound of the bicuspid valve, a stethoscope should be placed to the left of the sternum at the second intercostal space. -The left ventricular wall of the heart is thicker than the right wall in order to pump blood with a greater pressure. -When the atrioventricular bundle is completely interrupted the ventricles typically contract at 30 to 40 beats/min. -At late diastole, the atria and ventricles are relaxed…
