Cardiovascular System Anatomy Flashcards
Assuculation Def.
Sound Heart makes
Mediastinum Location
Anterior of thorax to between lungs (in thorax)
Divisions of mediastinum
Anterior mediastinum, middle mediastinum, posterior mediastinum (inferior mediastinum) and angle of louis (superior mediastinum)
Pericardium Outline
Double membrane inclosing Heart, consists of fibrous outer layer inner double serous layer (parietal and visceral). Pericardial fluid exists between 2 membranes in pericardial cavity
Attachments of Fibrous Pericardium
Great vessels, Diaphragm central tendon, sternum (sternopericardial ligament), sroues pericardiun parietal layer and pericardiul fluid
Pericardial Cavity Outline
Pericardial fluid outline, gives less friction (better gliding)
Heart Surfaces Structure
Anterior Surface, Left Pulmonary Surface, Diaphragmatic Surface, Right Pulmonary Surface and Base
Heart Has 4 Chambers
Right atrium, Right ventricles, left atrium and left ventricle
Right Atrium Source Flow
Superior and Inferior Vena Cava
Right Ventricle Out Flow
Pulmonary artery
Left Atrium Inflow
Pulmonary vein
Left Ventricle Outflow
Aorta
Valves in Pulmonary artery and aorta
Semilunar valves (pulmonary: left anterior, right anterior, posterior and aortic: left posterior, right posterior and anterior)
Valves between right atrium and ventricles
Tricuspid valve (anterior, septal, posterior)
Valves between left ventricles and atrium
Mitral (bicuspid) valve (anterior, posterior)
Chordae Tendane Function
Hold valves in place
Coronary Sinus Functions
Drains blood out of heart tissue into right atrium
What are contained in the aortic semilunar valves
Right valve = opening for coronary artery, posterior valve = aortic sinus and left valve = opening
Clavicle Def
Collar bone
Ascultation def
Sound heard through stethoscope
Pulmonary valve Location and ascultation
located 3rd costal cartilage and heard 2nd left intercostal space
Aortic valve location and ascultation
Located 3rd intercostal cartilage and heard 2nd right intercostal space
Mitral valve location and ascultation
Located 4th costal cartilage and heard 5th Intercostal left of clavical lines
