Blood enters the atrium of the fish heart and, as the heart relaxes, moves from the atrium through a valveinto the ventricle. (textbook page # 201)a.2 atria and 2 ventricles with valvesc.1 atrium and 1 ventricle, but no valveb.1 atrium and 1 ventricle with a valved.1 atrium and 2 ventricles with valves
While mammals have the most complex circulatory system, that of the fish is similar but less complex. It isa closed system. (textbook page # 200)
__d__8.(two marks)What treatment would a doctor use to treat a blocked coronary artery to prevent a heart attack orto repair the blockage after a heart attack?If angioplasty is not effective or appropriate, there are other procedures that can be used to treat blockagesof the coronary arteries. Coronary bypass surgery is the most common of these procedures. The name ofthis procedure is appropriate because the surgery uses a piece of a vein from another part of the body (avein graft) to bypass the blocked area of the coronary artery in order to supply blood to the area beyond theblockage. (textbook page # 204)
__d__9.(two marks)Which of the following is not a risk factor for heart disease?The exact causes of heart disease are difficult to identify; however, the main risk factors are smoking,physical inactivity, high blood cholesterol, high blood pressure, obesity, poor eating habits, diabetes, andheredity. (textbook page # 206)
__c__ 10.(two marks)How is the rate of heart contractions related to the pulse felt in your wrist?arteries stretch and increase in diameter. Where the arteries are near the surface of the body, this increase indiameter can be felt as the pulse. (textbook page # 198)Part B (Terminology): Matching (32 marks)Using your readings, match each term with the correct definitionprovided. The name of the term is given in the table and the definitions are listed below. Match the name of the term andthe corresponding definition. As part of your answer, identify the sources of your information. Each question is worth 2marks. - one for the matching and one mark for your proof.When recording normal levels for body system activity, it is important to use the correct units. Match the unitwith the measurement.Every time the heart beats, blood surges through the arteries. In response to this increase in pressure, thearteries stretch and increase in diameter. Where the arteries are near the surface of the body, this increase indiameter can be felt as the pulse. (textbook page # 198)a.the wrist pulse is slower because it is farther from the heartb.the wrist pulse is faster because you are feeling it directlyc.the wrist pulse is the same as the rate of heart contractionsd.the wrist pulse changes, but the heart rate stays the samea.% (percent)d. beats/minb. ºCe.breaths/minc.pH unitf.mm Hg
