Leukocytes, or white blood cells (WBCs), are crucial components of the immune system, protecting the body against infections and foreign invaders. There are several types of leukocytes, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, each with specific functions in the immune response. Neutrophils, for example, are the first responders to bacterial infections, while lymphocytes (such as T cells and B cells) are involved in adaptive immunity. Thrombocytes (platelets) are involved in blood clotting, erythrocytes (red blood cells) carry oxygen, and osteocytes are bone cells.

An agent given to counteract an unwanted effect of a drug is called an antidote. Antidotes are used to neutralize or mitigate the effects of poisons or overdoses of medications, ensuring patient safety and recovery from toxic exposures.
