  • Question 1
    1 / -0
    In an ECG, the depolarization of atria is indicated by

    Solution
    The P wave represents the wave of depolarization that spreads from the SA node throughout the atria, and is usually 0.08 to 0.1 seconds in duration. The wave of depolarization allows atrial contractions.
    So, the correct answer is option A.
  • Question 2
    1 / -0
    Hepatic portal system starts from

    Solution
    The hepatic portal system is the system of veins comprising the hepatic portal vein and its tributaries. The hepatic portal venous system is responsible for directing blood from parts of the gastrointestinal tract to the liver.  So, the correct answer is option A.
  • Question 3
    1 / -0
    Which of the following carries glucose from digestive tract to liver?
    Solution
    The liver is connected to two large blood vessels, the hepatic artery, and the portal vein. The hepatic artery carries blood from the aorta, whereas the portal vein carries blood containing digested nutrients from the gastrointestinal tract to  the spleen and the liver. 
    So, the correct answer is option B.
  • Question 4
    1 / -0
    ECG records
    Solution
    As the heart undergoes depolarization and repolarization, the electrical currents that are generated spread not only within the heart, but also throughout the body. This electrical activity generated by the heart can be measured by electrodes placed on the body surface. The recorded tracing is called an electrocardiogram. 
  • Question 5
    1 / -0
    In a standard ECG, which one of the following alphabets is the correct representation of the respective of the human heart?
    Solution
    • The P wave represents the wave of depolarization that spreads from the SA node throughout the atria and is usually 0.08 to 0.1 seconds in duration. 
    • The QRS complex represents ventricular depolarization. The duration of the QRS complex is normally 0.06 to 0.1 seconds. 
    • ST-segment following the QRS is the time at which the entire ventricle is depolarized. The ST segment is important in the diagnosis of ventricular ischemia or hypoxia. 
    • The T wave represents ventricular repolarization and is longer in duration than depolarization. 
    • The Q-T interval represents the time for both ventricular depolarization and repolarization to occur, and therefore roughly estimates the duration of an average ventricular action potential. 

    So, the correct answer is option D.
  • Question 6
    1 / -0
    The hepatic portal vein before reaching the liver, joins the
    Solution
    Anterior abdominal vein anastomoses with the inferior epigastric vein at the level of the umbilicus and drains the anterior part of the abdominal wall and some of the diaphragm. The hepatic portal vein is formed by the union of the superior mesenteric vein and the splenic vein. 
    So, the correct answer is option C.
  • Question 7
    1 / -0
    Largest blood vessel in body is

    Solution
    Largest blood vessel in the body is carotid systemic or dorsal aorta, It is a question marked shaped long vessel, that arise from left ventricle of the heart.
  • Question 8
    1 / -0
    An artifical pacemaker is implanted subcutaneously and
    connected to the heart in patients
    Solution
    When irregularity in the heart rhythm occurs, normal heart rhythm can be reared and maintained by surgically implanting an artificial pace maker, a device that sends out small electrical current to stimulate the heart to contract.
  • Question 9
    1 / -0
    pH of blood in artery and vein is

    Solution
    pH of blood is more in the vein as compared to that in the artery as the plasma of the vein contains deoxygenated blood and dissolved $$CO_2$$ in the form of bicarbonate ions. These ions increase the alkalinity of the plasma, therefore the pH value of blood is greater in the vein as to that of the artery
    So, the correct answer is 'More in vein and less in artery'
  • Question 10
    1 / -0
    All arteries carry oxygenated blood except:
    Solution
    • All arteries carry oxygenated blood except pulmonary artery.
    • The pulmonary artery is the artery that carries blood from the heart to the lungs. It carries deoxygenated blood from the heart to the lungs where it gets oxygenated.

    So, the correct answer is 'Pulmonary'.
