- carries blood from the lungs to the heart
- starts from the heart and ends in the lungs
- runs from capillaries of one organ to another
General

- 90-92 per cent
- 0.5-1 per cent
- 20-25 per cent
- 6-8 per cent
General
✓✗An Rh− person exposed to Rh+ blood will
- lose all ABO antibodies
- not show any reaction at all
- form specific antibodies against the Rh antigen
- become Rh+
General
✓✗The AV node is located in the
- right upper corner of the right atrium
- apex of the left ventricle
- lower left corner of the right atrium
- wall of the left ventricle
General

✓✗Which of the following vessels carries deoxygenated blood?
- Pulmonary artery
- Aorta
- Pulmonary vein
- Coronary artery
General
✓✗Glucose, amino acids and lipids present in plasma are
- permanent stores of plasma
- absent in healthy persons
- bound to haemoglobin
- always in transit in the body
General
✓✗If, due to some injury, the chordae tendineae of the tricuspid valve of the human heart are partially non-functional, what will be the immediate effect?
- The flow of blood into the aorta will be slowed down.
- The flow of blood into the pulmonary artery will be reduced.
- The pacemaker will stop working.
- The blood will tend to flow back into the left atrium.
General
✓✗Which WBCs are phagocytic cells that destroy foreign organisms entering the body?
- Neutrophils and monocytes
- Basophils and eosinophils
- Lymphocytes and basophils
- Eosinophils and lymphocytes
General
✓✗The tricuspid valve is formed of
- three semilunar pockets
- a single membranous fold
- two muscular flaps
- three muscular flaps or cusps
General
✓✗The AV bundle passes through the atrio-ventricular septa and divides into
- the SA node
- four branches
- right and left bundles
- Purkinje fibres only
General
✓✗The SA node is called the pacemaker because it
- is located in the left ventricle
- generates the most action potentials
- receives signals only from the brain
- is the largest node of the heart
General
✓✗Veins carry deoxygenated blood except the
- renal veins
- hepatic veins
- hepatic portal vein
- pulmonary veins
General
