White blood cells, also known as leukocytes, are a type of blood cell that plays a major role in the body’s immune system. They are produced in the bone marrow and circulate in the blood and lymph. White blood cells help to protect the body from infection by attacking and destroying harmful microorganisms, such as bacteria and viruses.
Carbohydrates are a type of nutrient that the body uses for energy. They are found in foods such as bread, pasta, rice, and potatoes. Carbohydrates are broken down into glucose, which is then used by the body’s cells for energy.
