دم (dam) is the Arabic word for "blood." It is a vital fluid in the human body that carries oxygen and nutrients to cells while removing waste products. Blood is composed of red blood cells, white blood cells, platelets, and plasma, each playing a crucial role in maintaining health and supporting bodily functions. In many cultures, دم is also significant in religious and cultural practices. For instance, in Islam, the consumption of blood is prohibited, and specific rituals involving blood, such as Qurbani (sacrificial offerings), are observed during Eid al-Adha. Understanding دم is essential for both medical and cultural contexts.
