    • Blood is a connective tissue that acts as a medium of transport of various substances that are needed for maintaining our body's metabolism.
    • The components of blood include RBCs, WBCs, Platelets, and Plasma.
    • The lymph is a typical small bean-shaped organ that is connected by the lymphatic vessels and acts as the drainage points across the whole lymphatic system.
    • Lymph is a colorless fluid as it consists of WBCs.
    Hence, Blood consists of RBCs and WBCs both while the lymph has the WBCs is the correct answer.
  • Question 3
    1 / -0
    Increase in count of RBC is
    Solution
    A. Polycythemia
    Reason: An increase in the number of red blood cells or Erythrocytes in the body is known as polycythemia. 

  • Question 4
    1 / -0
    Largest internal vein from alimentary canal to liver is
    Solution
    Hepatic portal vein  is a blood vessel that carries blood from gastrointestinal tract, gallbladder, pancreas and spleen to the liver. It is therefore the largest intestinal vein.
    So, option D is the correct option.
  • Question 5
    1 / -0
    Artificial pacemaker is implanted subcutaneously for correcting ______________.
    Solution
    The job of a artificial pacemaker is to artificially take over the role of heart's sinus node if it isn't working properly. Electrical impulses are sent by the artificial pacemaker to stimulate the heart to contract and regulate the rhythm of the heartbeat. 
    So, the correct option is D.
  • Question 6
    1 / -0
    Which one is hypothetical coagulating factor?
  • Question 7
    1 / -0
    Which one is not a blood group
    Solution
    C. Buffs and Kips
    Reason: A blood type (also known as blood group) is a classification of blood which is based on the presence or absence of inherited antigenic substances on the surface of red blood cells (Erythrocytes). These antigens may be proteins, carbohydrates, glycoproteins, or glycolipids, depending on the blood group system. Buffs and Kips are not blood groups or blood factors. Kip is a measure of force and buff is a breed of turkey. Lewis and Duffy, ABO and Rh, Rh and MN are types of blood groups. 
  • Question 8
    1 / -0
    How many times a red blood corpuscle will have to pass through the heart in its journey from hepatic artery?
    Solution
    B. Two times
    Reason: Double circulation occurs in human heart. So the blood present in hepatic artery get spread throughout the body and become deoxygenated. Then it will come to right atrium of the heart and sent towards lungs. After becoming oxygenated, it will come to to left atrium of the heart and reach to hepatic artery again. Red blood cells are present in blood. So, option B is correct.
  • Question 9
    1 / -0
    Abnormal fall in total count of WBCs in the human blood is called:
    Solution
    Leucopenia is the decrease in WBCs (white blood cells) in the blood. 
    This increases the chances of infection in body. WBCs are involved in the immunity of body and destroy foreign pathogens and particles. 
    However, the number of WBCs may also decrease due to acute infection and this leads to weak immunity. 
    Leucopenia have further subtypes depending upon which type of leucocytes are decreasing. 
    There are five types of leucocytes in our body, basophils, eosinophils, neutrophils, lymphocytes and monocytes. 
    If there is decrease in count of neutrophils, the condition is known as neutropenia. Most often, leucopenia occurs due to fall in neutrophils cells.
    So, the correct answer is 'Leucopenia'.
  • Question 10
    1 / -0
    Increase in blood pressure is
    Solution
    Hypertension is a condition in which blood pressure increases above systolic pressure (140 mm Hg) and diastolic pressure (90 mm Hg). This condition is also known as high blood pressure. It occurs due to emotional  stress and nervous tension that leads to contraction of arteries. It is one of the major causes of heart failure and stroke. Due to hypertension, the arteries of kidneys may get damaged and this causes chronic nephritis. 
    So, the correct answer is 'Hypertension'.
