👉 A dog's fluid, also known as plasma, is a vital component of their circulatory system, making up about 55% of their blood volume. This clear, colorless liquid is essential for transporting nutrients, oxygen, hormones, and waste products throughout the body. It also plays a crucial role in immune function by carrying white blood cells that fight infections and maintaining the balance of electrolytes and proteins. The composition of a dog's fluid is tightly regulated by various organs, including the liver, kidneys, and heart, ensuring that it remains within a narrow range to support optimal bodily functions.
