When you cut yourself, the blood clots to prevent the wound from bleeding. Clotting is caused by substances in the blood. Together with small particles called platelets, these substances produce masses to fine mesh when they are exposed to air. They block the the wound and prevent more blood loss. New cells grow rapidly into the wound, replacing the damaged tissue. Soon the clotted material, called a scab, falls off and clean, new skin is revealed underneath.

FACT FILE
Your blood pressure can be measured by a doctor with a special blood pressure monitor. During sleep your blood pressure decreases slightly, and during exercise and emotional excitement it increases.

With regards,
Lali.
