arteries |
| things that are clear in color and are formed in the red marrow of bones... |
platelets |
| Straw colored and is 91.5 percent water |
plasma |
| blood circulated from the heart to the lungs and back again to the heart |
pumonary circulation |
| blood cirulation from the left side of heart throughout the body and back again to the heart is... |
general circulation |
| paired artieries with numerous branches that supply the arms |
subclavian |
| consiste of a superior and an inferior opening |
vena cava |
| vein that carries the blood from the intestines to spleen and to the liver |
portal veins |
| consists of inferior and superior mesenteric vessels. they transport the blood from the inestines to the portal veins |
mesenteric |
| the aorta ends by dividing into two common arteries. each divides into an internal artery that supplies the pelvic cavity and an external artery that supplies the lower extermity |
Iliac arteries |
| provide blood to the head and brain |
Jular veins AND Carotid Artery |
| the most important artery of the human body, it brings oxygenated blood to the body's organsa and tissue |
Aorta |
| the arteriesbring blood to the lungs, The veins bring the oxygenated blood back to the heart |
Pulmonary Artery and Pulmonary Vein |
| the organ that supplies the necessary force to pump the blood around the body |
Heart |
| the organ that destroys old red blood cells and acts as a blood reserve |
Spleen |
| they provide blood to the kidneys |
Renal veins and arteries |
| consists of superior and inferior arteries that supply parts of the digestive system |
Mesenteric Arteries |
| a symptom of various diseases rather than being a specific disease, a deficiency of RBC's |
Anemia |
| Caused by genetics or exposure to poisons |
Blood Cell Destruction or Hemolytic Anemia |
| this can be fatal if not treated with B-12 and iron diet |
Decrease in RBC's or Pernicious Anemia |
| most common form of anemia |
Iron Deficiency |
| failure of bone marrow RBC to reproduce |
Aplastic anemia |
| chronic of acute loss of blood |
Hemorrhagic Anemia |
| Symptoms of Anemia... |
pallor, weakness, fatigue, dizziness, headache, difficulty breathing, heart palpitations, digestive disturbances |
| abnormal dilation of blood vessel, usually an artery due to a congenital defect or weakness of the vessel that can be caused by hyperextension, bacterial infection or injury |
Aneurysm |
| common locations of aneurysm |
abdominal aorta and cerebral |
| symptoms are shortness of breath, cough, difficulty swallowing, unequal radial pulse |
Abdominal Aorta |
| when this ruptures causes stroke (aka CVA = cerbral vascular accident) |
Cerebral |
| a chest pain caused by temporary insufficience of blood supply to the heart muscle, triggered by exertion and relieved by rest |
angina or angina pectoris |
| a thickening, hardening, and loss of elasticity in the wall of arteries. |
arteriosclerosis |
| form of arteriosclerosis, characterized by fibrous tissue, lipids, and calcium deposits. Walls of arteries filled with plaque |
artherosclerosis |
| the heart doesn't maintain adequate circulation of the blood |
congestive heart failure (CHF) |
| an abnormal heart sound. Produced by blood passing over a roughened valve, flowing through a constricted opening, flowing through a a defect between ventricles of flowing backwards through a valve that does not close correctly |
heart murmur |
| blood passing over a roughened valve |
rheumatic heart disease |
| Flowing over a constricted opening |
mitral stenosis |
| flowing backwards through a valve that does not close correctly |
mitral regurgitation |
| hereditary blood disorder characterized by prolonged bleeding time may also cause joint swelling |
hemophiliac |
| aka the silent killer, high blood pressure, increase in either systolic or diastolic pressure |
hypertension |
| top number in blood pressure reading, the pressure by which blood is forced through a constricted vessel |
systolic pressure |
| bottom number pressure by which blood is forced through a relaxed vessel |
diastolic pressure |
| to listen with a stethoscope, the sounds come from turbulence of blood passing through closed valves |
auscultation |
| blood pressure is measured with a blood pressure cuff and a stethoscope, together it is called... |
sphygmomonometer |
| low blood pressure may occur in shock, hemorrage, infection, fever, cancer, anemia and various other diseases |
hypotension |
| many varieties, but all involve excessive growth of leukocytes (wbc's) can be chronic or acute with a prognosis of 3 - 10 year depending on severity |
leukemia |
| a malignant growth of new tissue in the lymphatic system |
lymphoma |
| most common form of lymphoma, painless enlargement of lymph nodes, skin rashes, itchiness, fever, loss of appetite, weight loss 3-10 years prognosis |
hodgkins disease |
| is more malignant form of lymphoma and faster growing often with a prognosis of 4-6 months |
non hodgkins disease |
| swelling can be localized or systemic (within blood), tissues swell because they contain excess fluid. Common locations, feet, ankles, lower legs. |
edema |
| inflammation of a vein from injury, surgery or infection. Symptoms include pain and inflammation along the course of the vein and swelling |
Phelbitis |
| blood clot that travels is... |
embolism |
| indicates the presence of a blood clot |
thrombophebitis |
| Function of the lymphatic system is to collect and process (4) |
excess tissue fluid, invading micro organisms, damaged cells, protein molecules that are too large or toxic to return to blood through capillaries |
| the lymphatic duct that carries only a quarter of the lymph produced in the body from the right side of the body above the body, above the diaphragm |
right lymphatic duct |
| The lymphatic system's main drainage system, which carries lymph produced from the rest of the body |
thoracic duct |
| origin of the thoracic duct where the abdominal lymph vessels converge |
Pecquet's Cistern |
| small organs typically found where several lymph vessels converge. They play a part in the body's immune defense system |
Lymph nodes |
| tubes that begin as lymph capillaries and carry lymph throughout the body |
Lymph vessels |
