where is the heart located? in the middle left of the sternum in the anterior chest
three layers of tissue endocardium- smooth inner layer myocardium- muscular middle layer epicardium- serous outer layer
Atria/atrium upper chambers storage area SA node "pacemaker"
Ventricles lower chambers pumping chambers muscles
the right side ventricles is seperated by the myocardial septum
Coronary Circulation(heart) responsible for the movement of blood through the heart
Pulmonary Circulation(lungs) the flow of oxygen depleted blood from the right ventricle of the heart to the lungs for re oxygenation and then to the left atrium of the heart
Systemic Circulation the flow of oxygen enriched blood from the left ventricle of the heart to all parts of the body except the lungs and the return of oxygen depleted blood to the heart through the right atrium
lung facts.. the largest organs in the chest, located within the pleural cavities of the thorax, provide blood with oxygen and excretes carbon dioxide from the blood, pulmonary arteries carry blood to the lungs, pulmonary veins carry blood from the lungs,
alveoli located deep in the lungs known as the air sacs, responsible for the exchange of oxygen and carbon dioxide
myocardial contusion severe blow to the chest, or a bruising of heart muscle
aortic rupture intense forward/backward motion that fx's the aortic arch, severe blow to the chest
rib fracture a direct blow or fall to the rib cage
pneumothorax the presence of air in the thoracic cavity resulting from the perforation of the chest wall or the visceral pleura
hemothorax blood within the pleural cavity, a condition in which blood collects between the lung and chest wall in the pleural cavity
thorax(chest) the thorax is seperated from the abdominal cavity by a muscle called the diaphragm
thoracic cavity houses two very important organs the heart and lungs
hyperventilation deep and rapid breathing resulting in decreased levels of CO2 in the blood
flail chest a conditiob in which two or more fractures on a given rib cause the chest wall to become unstable resulting in respira
