Question | Answer |
The hollow muscular organ | Heart |
sends oxygenated blood away from the heart | Artery |
Exchanges nutrients with cells. | Capillaries |
Gets blood from all body tissues. -Oxygen poor- | Veins |
Brings oxygen to all cells. Important in immune and endocrine system. | Blood |
relatively pure, into the carotid arteries taking blood to the head (and brain) | Oxygenated Blood |
Cardiology Blood with a low O2 saturation relative to blood leaving the lungs | Deoxygenated Blood |
Double walled membrane sac, encloses the heart | Pericarium |
Prevents friction when heart beats | Pericardium |
Outter layer of heart, inner layer of pericardium sac | Epicardial |
Consists of cardiac muscle, middle and thickest layer of heart | Myocardium |
Inner lining of heart, direct contact with blood pumping; smooth | Endocardium |
Both upper chambers of heart, gets blood from all parts of the body. Blood vessels come into the heart | Atria |
Both lower chambers of the heart, pumps blood to all body tissue. | Ventricles |
Seperating wall, located betweem right and left artia. | Septum |
Narrow tip of the heart. | Apex |
Carries deoxygenated blood to upper half of the body. | Superior vena cava |
Largest artery in the body, extends from left ventrical to abdomen. | Aorta |
Carries blood to lower half of the body. | Inferior vena cav |
Carry blood from heart to lungs. | Pulmonary artery |
One of four vessels that carries blood from the lungs to left atrium. | Pulmonary vein |
Connection between artery and veins. | Capillaries |
Blood must have fresh supply of oxygen. | Artery |
Receives waste products from blood. | Veins |
Tightens, pumps blood in a sequence. | Contraction |
Releases, and expands, pumps blood in correct sequence. | Relaxation |
nerve stimulate myocardium, determines rate and regulatory heart beat. | Electrical Impulses |
1st and 2nd heart sound, makes heart sounds when closing valves. | Lubb/Dubb |
Measures pressure by the pressure against the walls of the vessels. | Blood Pressure |
Occurs when ventricle contracts, highest pressure agianst walls. | Systolic |
Happens when ventricle relaxes, low pressure against walls. | Diastolic |
130/84 mm. Hg | Normal Adult Pressure |
