What are white blood cells known as?

  1. Erythrocytes

  2. Deltoid

  3. Tricep

  4. Leucocytes

The correct answer is: Leucocytes

White blood cells are commonly known as leucocytes. These cells are a crucial component of the immune system, helping to defend the body against infections and foreign invaders. Leucocytes play various roles, including identifying and destroying bacteria, viruses, and other pathogens, as well as facilitating immune responses. Erythrocytes, on the other hand, are red blood cells responsible for transporting oxygen throughout the body, and the terms deltoid and tricep refer to muscles in the body, not blood cells. Understanding the function and classification of blood cells is essential in fields such as esthetics, where knowledge of overall health can influence skin and body care strategies.
