Biology Question Bank for Entrance Exams

For AIPMT Main other Medical Entrance Exam Prepration, Question Bank for Biology Body fluids and Circulation is given below.IMPORTANT POINTS

  • The cells of every animals need O2 and nutrients for performing different metabolic activities, and same way end of this process CO2 and wastes are removed. Hence body fluid is flow throughout the body by blood and lymph. Blood as a fluid connective tissue made of body corpuscles.
  •   In the composition of blood plasma, water, salts and proteins are included. It covers 55% of blood. RBC, WBC and platelets are included in blood corpuscles. It covers 45 % of blood.
  •   In human ABO and Rh blood groups are found. In which A, B, AB and O blood groups are included in ABO, while Rh+ve and Rh–ve included in Rh group.


  •  The major chemical defense against blood loss is the formation of blood clot. In it 13 factors are included. This process involves three phases

(i) Formation of thromboplastin

(ii) Formation of thrombin

(iii) Formation of fibrin

  • The composition of lymph is similar to blood plasma. It flows in body through lymphatic vessels.
  •  Human having close circulation. In it blood vessels (artery, vein and capillaries) and heart are included.
  •  Human heart having four chambers, in which two auricles and two ventricles are included. Many valves are seen in the structure of heart. It regulates the direction of blood flow.
  •   Blood with O2 and without O2 flow separately in human, for that it is called double circulation.
