Flashcards in Heart Circulation Deck (38):
Space between the lungs
Surrounding Membrane of the heart
Inner membrane of paricardium
Inner layer of the Serous Paricardium. EPICARDIUM
Outer layer of the Serous Paricardium.
Fluid within paricardial sac
Complete blockage of an artery that supplies oxygen to the heart muscle.
Seperates the two atria down the middle.
Seperates the two ventricles down the middle.
Lower portions of the heart. PUMPS blood to the body.
Upper portions of the heart. RECEIVES blood from the body.
Veins that collect blood that is returning from the walls of the heart.
Opening between the two atria that is present in the fetus.
Valves that are between that atria and ventricle.
Seperates RIGHT ATRIUM and RIGHT VENTRICLE
Seperates LEFT ATRIUM and LEFT VENTRICLE
Between the ARTERIES and VENTRICLES.
Between the right ventricle and pulmonary arterie. Prevent Backflow.
Between the left ventricle and the aorta (systemic arterie). Prevent Backflow.
Superior Vena Cava
Returns deoxygenated blood from the UPPER BODY to heart via the right atrium.
Inferior Vena Cava
Returns deoxygenated blood from the LOWER BODY to heart via the right atrium.
Largest artery in body.
Largest of the four cardiac chambers, and is responsible for pumping blood to the entire body.
Receives oxygenated blood from lungs.
Receives deoxygenated blood from body.
Pumps deoxygenated blood to the lungs.
lub. CONTRACTION. Closure of the mitral and tricuspid valves.
DUB. RELAXATION. Closure of the pulmonic and aortic valves.
da. After S2. Soft and low pitched. "lub-DUB-da". Typically rapid ventricular filling due to inrush of blood. Can be an indication of heart failure.
bla. Before S1. Increased arterial pressure OR decreased compliance of the left ventricle.
Infection or Inflammation of the paricardial membrane. Chest pain!
Pericardial Sac fills with too much fluid
Pericardial Effusion with shock due to the hearts inability to fill effectively.
Needle placed into the pericardial sac to remove fluid.
Damage to aortic and mitral valves. Forward blood flow is decreased. Normally in young adults or children.
Damage to cells. Arterial blood flow to heart tissue is decreased resulting in a lack of oxygen to that site.
