👉 The vital fluid, also known as plasma, is the most abundant component of blood and plays a crucial role in maintaining homeostasis and supporting various bodily functions. It makes up about 55% of blood volume and contains water, proteins, nutrients, hormones, waste products, and cells. Vital fluid acts as a medium for transporting nutrients, oxygen, and hormones to tissues while removing waste products like carbon dioxide. It also helps regulate body temperature, blood pressure, and pH levels, ensuring that organs function optimally. In essence, the vital fluid is essential for sustaining life and maintaining overall health.
