Haemophilia a medical condition in which the ability of the blood to clot is severely reduced, causing the sufferer to bleed severely from even a slight injury. The condition is typically caused by a hereditary lack of a coagulation factor, most often factor VIII. hemolytic disease most frequently occurs when an Rh negative mother has a baby with an Rh positive father. When the baby's Rh factor is positive, like the father's, problems can develop if the baby's red blood cells cross to the Rh negative . Tuberculosis -- or TB, as it's commonly called -- is a contagious infection that usually attacks the lungs. It can also spread to other parts of the body, like the brain and spine.

b) SA node
0%
c) AV bundle
0%
d) Purkinje system
Explanation
The AV node, which controls the heart rate, is one of the major elements in the cardiac conduction system. The AV node serves as an electrical relay station, slowing the electrical current sent by thesinoatrial (SA) node before the signal is permitted to pass down through to the ventricles. The SA node is the heart's natural pacemaker. The SA node consists of a cluster of cells that are situated in the upper part of the wall of the right atrium (the right upper chamber of the heart). The electrical impulses are generated there. The SA node is also called the sinus node. AV bundle a bundle of specialized muscle fibers regulating the heartbeat by conducting impulses from the right atrium to the ventricles. Expand. Also called bundle of His. atrioventricular bundle in Medicine.atrioventricular bundle Purkinje system a network of Purkinje fibers that carry the cardiac impulse from the atrioventricular node to the ventricles of the heart and causes them to contract. Answer : (b)

Explanation
Thyroxine is the main hormone secreted into the bloodstream by the thyroid gland. It plays vital roles in digestion, heart and muscle function, brain development and maintenance of bones. Adrenaline is a hormone released from the adrenal glands and its major action, together with noradrenaline, is to prepare the body for fight or flight, to situations that are high-stress, dangerous and/or physically exhilarating. Glucagon is a peptide hormone, produced by alpha cells of the pancreas. It works to raise the concentration of glucose and fat in the bloodstream Gastrin is a peptide hormone that stimulates secretion of gastric acid (HCl) by the parietal cells of the stomach and aids in gastric motility. It is released by G cells in the pyloric antrum of the stomach, duodenum, and the pancreas. Answer : (b)
