Dissection

Dissection is the process of cutting up the tissue of a dead or live animal or plant, to do anatomical studies and surgical treatments. The purpose of dissection is to learn more about the overall structure of organs and organ systems and thereby understand the physiology of the organism.

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.

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…
Which of the following is correct regarding the flow of blood in reference to the left side of the heart? a. Blood flows from the left atrium, through the bicuspid valve, into the left ventricle, through the aortic semilunar valve, and then into the aortic arch b. Blood flows from the left atrium, through the aortic semilunar valve, into the left ventricle, through the bicuspid valve, and then into the aortic arch c. Blood flows from the left atrium, through the bicuspid valve, into the left ventricle, into the aortic arch, through the aortic semilunar valve, and then into systemic arterial system
