Introduction to A Local Reaction and Chemical Entry into the Bloodstream

When chemicals enter the body, they can trigger local or systematic reactions. Among these, a local reaction is one of the most common outcomes, in which the chemical agent elicits an effect near the site of contact with body tissues. This may occur when chemicals are absorbed through the skin, respiratory mucosa, or eyes and enter the bloodstream.

Physical and Chemical Properties of the Entering Substances

The physical and chemical properties of the entering substances are critical determinants of the resulting local or systemic responses. For instance, irritants, allergens, caustic agents, and other types of toxic chemicals may have different modes of action and effects on the body. The degree of exposure and concentration of the substance also play a significant role in the response.

The Role of Immune System in Local Reaction to Chemicals

The immune system plays a vital role in determining the severity and nature of local reactions to chemicals. When the chemicals enter the bloodstream, certain cells of the immune system, such as mast cells and basophils, release histamine and other chemicals that trigger inflammatory responses. This response can cause swelling, redness, and pain near the site of contact.
