Cardiovascular System
| Question | Answer |
|---|---|
| What is the function of the circulatory System ? | Supplies the body with nutrition and oxygen |
| What are the chambers of the heart ? | Two upper chambers are called atria (receiving chambers): Right and left atria Two lower chambers called ventricles (discharging chambers): Right and left ventricles |
| What are the 3 layers of the heart? | Endocardium = inner layer ,Thin layer of smooth tissue that lines the heart chambers Myocardium = middle layer , it is called the heart muscle or cardiac muscle , responsible for the pumping action of the heart. Epicardium = outer layer |
| Different valves of the heart ? | Mitral valve = located between the left atrium and the left ventricle Tricuspid valve = located between the right atrium and right ventricle Pulmonary valve = located between the right ventricle and pulmonary artery Aortic valve = located between the left ventricle and the aorta |
| What is the pericardium ? | Connective tissue surrounding heart; anchored by ligaments to chest wall and diaphragm.Fibrous tissue that covers the heart |
| Where is the heart located ? | the heart sits in the chest cavity between the lungs. It is a large muscle about the size of a fist . |
| capillary | A tiny vessel that connects the ends of the smallest arteries to the smallest veins . |
| venules | blood vessel carries blood away from the capillaries |
| Vein | A blood vessels that carries deoxygenated blood. Carry Blood towards the heart. The walls are thin. |
| Artery | A vessel that carries oxygenated blood. Carries blood away from the heart . Blood flows under high pressure. They have no valves and are thick walled. |
| Location and position of the apex of the heart . | just below the clavicle; pointing towards the left lung |
| Pulmonary artery | Carries oxygen poor blood from the right ventricle to the heart to the lungs. |
| Pulmonary vein | Carries oxygen rich blood .Carries blood from the lungs to the heart . |
| The sequence of an impulse moving through the conduction system of the heart is | sinoatrial node, atrioventricular node, bundles of His, Purkinje fibers. |
| Valve stenosis | Narrower than normal valve that slows blood flow from the heart chamber |
| Fibrillation | Cardiac muscle fibers contracting rapidly and out of step with each other |
| Cardiac output | Amount of blood pumped by one ventricle per minute |
| stroke volume | Volume of blood pumped from the ventricles with each heartbeat |
| Bradycardia | Heart rate less than 60 beats per minute |
| Angina pectoris | Severe chest pains |
| Ductus venosus | structure in the fetus connects the pulmonary artery to the aorta |
| What sequence of an impulse moving through the conduction system of the heart? | sinoatrial node, atrioventricular node, bundles of His, Purkinje fibers |
| Neurologic shock | Type of shock results from a loss of sympathetic impulses sent to the smooth muscles of the blood vessels. |
| Foramen ovale | structure in the fetus allows blood to be shunted from the right atrium to the left atrium |
| aneurysm | Condition in which an artery becomes abnormally widened due to a weakness in the arterial wall is calle |
| Aortic semi lunar valve | opens from the left ventricle into the artery. |
| ductus arteriosus connects | connects the pulmonary artery to the aorta |
| What are the causes of heart failure ? | Valve disorder Cardiomyopathy Cor pulmonale |
| What is the other term for CHF ( Congestive heart failure ) | Left sided heart failure |
| right and left coronary arteries | first branches of the aorta |
| What is a cardiac Cycle ? | Cardiac cycle is series of events that occur for one complete heartbeat There are two sequences: Systole and diastole |
| What is Systole ? | The period when the heart is contracting . |
| What is Diastole ? | The period when the heart is in a state of relaxation and dilation. |
| What is blood pressure ? | Force exerted by blood against inner blood vessel walls Cardiac output (CO): Increase means increased blood pressure and flow Increased blood volume may cause increased blood pressure |
| What is MI ? | Heart attack . Tissue death occurs |
| What are the first branches of the aorta ? | right and left coronary arteries |
| How many cardiac takes about to determine the cardiac output? | 72 cardiac cycles |
| Tunica externa | layer of the blood vessel is made of tough connective tissue |
| Ductus venosus | structure in the fetus allows blood to bypass the immature liver |
| aneurysm | The condition in which an artery becomes abnormally widened due to a weakness in the arterial wall. |
| What causes the T wave of an electrocardiogram to occurs? | repolarization of the ventricles. |
| What causes the QRS complex of an electrocardiogram occur? | depolarization of the ventricles |
| ductus arteriosus | connects the pulmonary artery to the aorta |
| Intercalated disks | Are structures in heart cells that improve the efficiency of impulse conduction through the heart. A special junction complex between two cardiocytes. |
| Cardiomyopathy | Chronic disease of the heart muscle. |
| Congestive heart failure | Another term for left-sided heart failure. |
