Blood is approximately how much percent water?

Blood is composed of approximately 80% water, which serves several vital functions within the body. The high water content is crucial for maintaining blood volume and viscosity, facilitating the transport of nutrients, hormones, and waste products throughout the circulatory system. Additionally, water in the blood helps regulate body temperature and provides a medium for biochemical reactions to occur.

Understanding the composition of blood, including its water content, is important for anyone in cosmetology and related fields, as hydration plays a significant role in overall health and the condition of skin and hair. Adequate hydration can influence how treatments work and the overall appearance of clients, underscoring the relevance of biological knowledge in the practice of cosmetology.
