Answer 1

Answer. Throbbing pain at the cut site has been observed because of the arterial pulsations which produce repetitive wave sensations. Inflammatory chemicals are also released at the wounded site as a part of body defense to prevent further infection with this wound. These chemicals stimulate the sensory receptors in the skin. So, as heart throbs with the heart beat, it stimulates these sensory nerve endings and causes pain.

Inflammation at the wounded site is characterized by heat redness, swelling and pain. Inflammation causes the release of chemicals from the wounded site that cm causes heat and warmth. These chemicals also cause fluid leakage that leads to swelling, it also innervates the nerves of that area, accounting for pain at the wounded site.
