 What is  a Pacemaker?

3.16 Two small groups of cells in the wall of the heart set the pace for cardiac contraction. They are the heart’s natural pacemaker. Sometimes disease causes these cells to become slow in their initiation of the contraction. If medication does not help, doctors can insert an electronic, artificial pacemaker near the heart. This pacemaker is battery-operated, and wires from it send a small electric impulse to the heart at regular intervals.

 How does Blood Clot?

3.17   The body has a special way of mending itself. When a blood vessel is cut, platelets are triggered off to produce a clotting substance, which sticks to the edges of the cut. This joins with other clotting substances to form thread-like strands, which get tangled together, trapping blood cells between them. They then release chemicals which react with plasma proteins to form a blood clot. The blood makes a kind of crust, called a “scab” over the cut. The drying scab also keeps germs out of the body until the cut has healed. That is why we should never pick and remove a scab. After some time when the skin underneath has healed, the scab falls off by itself.
