Cardiovascular Sytm

Circulatory system known as the cardiovascular system consists of the heart, blood vessels, and blood
endocardium a smooth layer of cells that lines the inside of the heart and is continuous the inside of blood vessels
myocardium the thickest layer, the muscular middle layer
percardium doubled layered membrane sac, that covers the outside of the heart
septum a muscular wall that separates the heart into a right side and a left side
right atrium receives blood as it returns from the body cells
right ventricle receives blood from the right atrium and pumps blood into the pulmonary artery, which carries the blood to the lungs for oxygen
left atrium receives oxygenated blood from the lungs
left ventricle receives blood from the left atrium and pumps the blood into the aorta for transport to the body cells
tricuspid valve located between the right atrium and right ventricle contracts allowing blood to flow to the lungs and preventing blood from flowing back into the right atrium
pulmonary valve between the right ventricle and pulmonary artery a blood vessel that carries blood to the lungs
mitral valve located between the left atrium and left ventricle It closes when the left ventricle is contracting allowing blood into the aorta and prevent blood flowing back into the left atrium
aortic valve biggest artery in the body. it closes when left ventricle is finished contracting. allow blood back to the aorta prevent flow to the left ventricle
diastole cycle consist of a brief period of rest
systole period of ventricular or contraction
Arteries carry blood away from the heart
Capillaries connect arterioles with venules, the smallest vein
Veins are blood vessels that carry blood back to the heart
Blood flows through the circulatory system often called tissues for its different types of cells
Plasma approximately 90 percent water, with many dissolved or suspend minerals
Erythrocytes red blood cells, are produced in the red bone marrow at a rate of one million per minute
hemoglobin a complex protein composed of the protein molecule called globin and the iron compound called heme.
Leukocytes white blood cells, are not as numerous as are erythrocytes
Arrhythmia abnormal heart rhythm and is mild to life threatening
PAC premature atrial contraction
Defibrillator a device that shocks the heart with an electrical current to stop the coordinated contraction of the heart and allow the SA node to regain control
Pacemaker a small battery powered device with electrodes
CHF congestive heart failure
Aneurysm a ballonning out of, or saclike formation on an artery wall
Atherosclerosis when fatty plaques are depoisted on the wall of the arteries
embolus a foreign substances circulating in the bloodstream
Hyportension high blood pressure
MI myocardial infraction
Phlebitis an inflammation of a vein, frequently in the leg
Anemia an inadequate number of red blood cells, hemoglobin, or both.
Arteriosclerosis a hardening or thickening of the arterial walls resulting in a loss of elasticity
Hemophilia an inherited disease that occurs almost exclusively in males but can be carried in females
Varicose veins dilated, swollen veins that have lost elasticity and causes decreased blood flow
