✔✔A hollow, muscular organ that pumps blood throughout the body. - ✔✔Heart
✔✔heart, blood vessels, blood - ✔✔Three primary components of the circulatory system
✔✔The fibrous sac that surrounds the heart. - ✔✔Pericardium
✔✔muscular, middle layer of the heart - ✔✔Myocardium
✔✔inner lining of the heart preventing blood clots - ✔✔Endocardium
✔✔blood that contains little oxygen - ✔✔Deoxygenated blood
✔✔Blood rich in oxygen - ✔✔Oxygenated blood
✔✔Right atrium - ✔✔Deoxygenated blood from the body returns to the:
✔✔right ventricle - ✔✔pumps deoxygenated blood to the lungs via the pulmonary artery
✔✔left ventricle - ✔✔Pumps oxygenated blood into the aorta
✔✔Largest artery in the body - ✔✔Aorta
✔✔pulmonary artery - ✔✔artery carrying oxygen-poor blood from the heart to the lungs
✔✔vena cava - ✔✔a large vein carrying deoxygenated blood into the heart
✔✔Arteries - ✔✔Blood vessels that carry blood away from the heart
✔✔Arterioles - ✔✔Dilate and contract to control blood flow into the capillary bed
✔✔Capilleries - ✔✔allow gas exchange to occur. They are thin, have single cell walls.
✔✔Venules - ✔✔Dilate and control blood flow out of the capillary bed, returning blood
back to the heart
✔✔Veins - ✔✔carry blood back to the heart
✔✔adult has how many liters of blood - ✔✔5 liters
, ✔✔coronary circulation - ✔✔circulation of blood through the coronary blood vessels to
deliver oxygen and nutrients to the heart muscle tissues
✔✔blockage of coronary artery results in? - ✔✔Angina or heart attack
✔✔pulmonary circulation - ✔✔Deoxygenated blood passes from the right side of the
heart to the lungs via the pulmonary artery
✔✔systemic circulation - ✔✔Oxygenated blood from the lungs enters the left side of the
heart, where it is ejected through the aorta to deliver blood to tissues.
✔✔clinical shock - ✔✔Clinical shock is a state of insufficient blood flow to the tissues of
the body as a result of problems with circulatory system.
✔✔Cardiogenic shock causes - ✔✔Poorly functioning heart
Trauma to the heart muscle
AMI (acute myocardial infarction) Heart attack
✔✔Heart attack - ✔✔Acute myocardial infarction
✔✔Hypovolaemic shock - ✔✔Caused by too little fluid in the circulatory system.
✔✔anaphylactic shock - ✔✔An overwhelming internal reaction of the body systems
caused by reactions to injections, bites, stings, food and drugs
✔✔neurogenic shock - ✔✔Caused by inefficient nervous control of blood vessels
through disease resulting in bradycardia hypotension and flushing below the injury site
✔✔Sepsis - ✔✔Due to peritonitis, meningococcal meningitis and other infections
✔✔coronary artery disease - ✔✔Narrowing of coronary arteries as a result of build up of
fat deposits creating plaques
✔✔Angina - ✔✔Diagnosis of symptoms which result from narrowed coronary arteries. A
temporary condition relieved with rest and medication
✔✔heart attack - ✔✔Sudden and complete obstruction of the coronary artery, resulting
death of part of the heart muscle.
✔✔Ischaemia - ✔✔Lack of blood supply
✔✔heart failure - ✔✔a chronic condition in which the heart is unable to pump out all of
the blood that it receives
