The given figure shows an angiogram of the coronary blood vessel. Which one of the following statements correctly describes, what is being done ? A. It is a coronary artery which has a cancerous growth that is being removed.B. It is a coronary artery which is blocked by a plaque and the same is being crackedC. It is a coronary vein in which the defective valves are beings openedD. It is coronary vein blocked by a parasite (blood fluke) that is being removed. |
|
Answer» Correct Answer - B Angiogram is an X-ray diagnotic procedure used to visualise the blood vessels following injection of a contrast substance into an artery. Cononary angiography is used to detect obstruction in the coronary arteries, due to presence of atherosclerotic plaques which can leads to heart attack. To clear to passage, a very small balloon tipped catheter is inserted into the coronary artery under X-ray observation. Then the balloon is inflated with air to destory the plaques, thereby clearing the lumen of the blood vessel for blood flow. This procedure is known as cornoary artery angioplasty. |

Define a cardiac cycle and the cardiac output. |
|
Answer» Cardiac cycle. A regular sequence of three events : (i) auricular systole, (ii) ventricular systole, and (iii) joint diastole or complete cardiac diastole (relaxation of both auricles and ventricles) during the completion of one heart beat is known as heart cycle or Cardiac cycle. Cardiac output. The volume of blood pumped by the left ventricle into the systemic circuit per minute is called cardiac output or heart output. Heart beats 72 times per minute and pumps out about 70 ml of blood during each beat. Therefore, `72xx70` or 8040 ml (roughly 5 litres) is the Cardiac output. |

Assertion : The process of clotting can occur in absence of all cellular elements except platelets Reason : Vitamin K is essential for blood clotting.A. If both assertion and reason are true and reason is the correct explanation of assertionB. If both assertion and reason are true but reason is not the correct explanation of assertionC. If assertion is true but reason is falseD. If both assertion and reason are false |
|
Answer» Correct Answer - B Activated platelets are essential for blood clotting because several of the cascade reactions take place on the surface of platelets. Vitamin K is essential for production of prothrombin. Prothrombin and many plasma clotting factors are produced in the liver. The liver requires vitamin K to produce prothrombin and several other clotting factors. |

Closed circulatory system occurs inA. cockroachB. tadpole/fishC. mosquitoD. house fly |
|
Answer» Correct Answer - B ( b) Closed circulatory system is usually high pressure system, in which blood flows in closed tubular structures called blood vessels ( arteries, veins and capillaries ). It is found in most of annelids, cephalopods , among the molluscs and all vertebrates including human beings. In this type of system these is no direct contact between body tissues and blood.

Which one of the following statements is correct regarding blood pressure ?A. 100/55 mm Hg is considered an ideal blood pressureB. 105/50 mm Hg makes one very active.C. 190/110 mm Hg may harm vital organs like brain and kidneyD. 130/90 mm Hg is considered high and requires treatment. |
|
Answer» Correct Answer - C ( c) Blood pressure [190/110 mm Hg) of an individual is 140/90 [140 over 90] or higher, it shows hypertension. High blood pressure [190/110 mm Hg) lead to heart diseases and also affects vital organs like brain and kidneys. Hypernation means the blood pressure that is higher than normal [120/80]. In this measurement, 120 mm Hg ( milimeter of mercury pressure ) is the normal systolic or pumping, pressure and 80 mm Hg is the normal diastolic or resting pressure. |

The given figure is the ECG of a normal human. Which one of its components is correctly interpreted below ? A. Peak T-initiation of total cardiac contractionB. Peak T-initiation of total cardiac contractionC. Peaks P and R-systole end diastole blood pressureD. Peak T-initiation of left atrial contraction only |
|
Answer» Correct Answer - A Obviously, by counting the number of QRS complexes that occur in a given time period, one can determine the heart beat rate of an individual. Since the ECGs obtaineed from different individuals have roughly the same shape for a given lead configuration, any deviation from this shape indicates a possible abonrmality or disease. Hence, it is of a great clinical significance. |
