Cardiovascular system
Question | Answer |
---|---|
List some possible diseases/syndromes related to the cardiovascular system | Heart attack, Angina, Damaged heart valve |
Describe some of the possible treatment options available to patients with cardiovascular disease | Medication to decrease blood pressure and cholesterol and C.A.B.G or bypass surgery |
What type of lifestyle changes could be recommended to patients with diseases of the cardiovascular system? | Exercise, diet, lose weight, no smoking, decrease in fats and cholesterol |
List some outcomes of diseases of the cardiovascular system | Death, kidney failure, stroke and heart attack |
Describe the location and function of the atria | located above the ventricles and they receive blood |
Describe the purpose of the bicuspid valve | allows blood flow from left atrium to left ventricle when valve is open |
In which blood vessels is the pressure the highest? | arteries; carry blood away from the heart |
Define stroke volume | Volume of blood pumped by ventricle and heart (mls/beat) |
List some factors that increase peripheral resistance | Narrowing/constricting of blood vessels, increased blood pressure(pregnancy, increased stroke), exercise increases CO2 |
Which vessels drain blood into the right atrium? | Superior Vena Cava and Inferior Vena Cava |
How does the heart's ability to contract differ from that of other muscles of the body? | Contract independently without rest or nerve stimulation. Heart muscle combination of nerve tissue or muscle tissue. Has intrinsic conduction system- nudal system. Synatrical node sets place and medulla acts as brake and accelerator |
What monosyllables are used to describe heart sounds? Explain the causes of the heart sounds | "Lup" - closing of the tricuspid and bicuspid valves "Dup" - closing of the semi lunar valves and after ventricles contract |
Describe arteries, capillaries and veins. Compare and contrast the blood vessels | All blood vessels carry blood. Arteries carry blood away from the heart with the highest pressure. Veins carry blood toward the heart with the pressure being the lowest. Capillaries: exchange occurs(gas exchange) link arteries and veins |
