Q.2
Which one of the following is correct?
  • Lymph = Plasma + RBC + WBC
  • Blood = Plasma + RBC + WBC + Platelets
  • Plasma = Blood - Lymphocytes
  • Serum = Blood + Fibrinogen
Q.3
Erythropoiesis starts in
  • Spleen
  • Red bone marrow
  • Kidney
  • Liver
Q.4
Serum differs from blood in
  • Lacking globulins
  • Lacking albumins
  • Lacking clotting factors
  • Lacking antibodies
Q.5
Cardiac output is determined by –
  • Heart rate
  • Stroke volume
  • Blood flow
  • Both a and b
Q.6
Pacemaker is
  • Instrument for measuring heart beat
  • Instrument for measuring pulse rate
  • Auriculo-ventricular node that provides impulse for heart beat
  • Sinu-aurical node that provides impulse for heart beat
Q.7
The cells involved in inflammatory reactions are
  • Eosinophils
  • Basophils
  • Neutrophils
  • Lymphocytes
Q.8
How do parasympathetic neural signals affect the working of the heart?
  • Reduce both heart rate & cardiac output
  • Heart rate is increased without affecting cardiac output
  • Both the heart rate & cardiac output increase
  • Heart rate decreases but cardiac output increases
Q.9
Heart is covered by
  • peritoneum
  • placenta
  • pleural membrane
  • pericardium
Q.10
Electrocardiogram is a measure of –
  • Heart rate
  • Ventricular contraction
  • Volume of blood pumped
  • Electrical activity of heart
Q.11
Which among the following is correct during each cardiac cycle?
  • The volume of blood pumped out by the Rt and Lt ventricles is same.
  • The volume of blood pumped out by the Rt and Lt ventricles is different
  • The volume of blood received by each atrium is different
  • The volume of blood received by the aorta and pulmonary artery is different
Q.12
Person with blood group AB is considered as universal recipient because he has
  • Both A & B antigens on RBC but no antibodies in the plasma
  • Both A & B antibodies in the plasma
  • No antigen on RBC & no antibody in the plasma
  • Both A & B antigens in the plasma but no antibodies
Q.13
Which one engulfs pathogens rapidly
  • neutrophils
  • monocytes
  • basophil
  • Both A & B
Q.14
A specialised nodal tissue embedded in the lower corner of the right atrium, close to Atrio-ventricular septum, delays the spreading of impulses to heart apex for about 0.1 sec. This delay allows
  • the atria to empty completely.
  • blood to enter aorta.
  • the ventricles to empty completely.
  • blood to enter pulmonary arteries.
Q.15
How is blood pressure created
  • force of blood against artery wall
  • force of blood in the heart
  • force of blood in the lungs
  • force of blood in the goodwin
Q.16
How does the lymphatic system help maintain homeostasis?
  • It returns lost fluids to the circulatory system to maintain blood volume and pressure
  • It pumps blood throughout the body
  • It aids in gas exchange with the lungs
  • In moves the skeletal muscles
Q.17
"Bundle of His" is a network of
  • Muscle fibres distributed throughout the heart walls
  • Muscle fibres found only on the ventricle wall
  • Nerve fibres distributed in ventricles
  • Nerve fibres found throughout the heart
Q.18
Typical lub-dub sound heard in heart beat are due to
  • Closing of bicuspid and tricuspid valves followed by semilunar valves.
  • Closing of semilunar valves
  • Blood pressure through aorta
  • Closer of bicuspid valves
Q.19
Fully mature human RBC has......
  • A Nucleus
  • No nucleus
  • Nucleus may or may not be present
  • None of the above
Q.20
Valves are important in the heart because they...
  • Create the heart beat
  • Are vessels that carry blood
  • Prevent back flow as blood moves through the heart
  • House white blood cells
