👉 The feeds fluid, also known as the blood plasma, is a critical component of the circulatory system that serves as the medium for transporting nutrients, oxygen, hormones, and waste products throughout the body. Composed primarily of water (about 90%), it also contains proteins, electrolytes, glucose, lipids, and various other dissolved substances. This fluid acts as a transport medium for cells, facilitating the exchange of materials necessary for cellular function and maintaining homeostasis. Additionally, it plays a crucial role in immune responses by carrying antibodies and white blood cells, and it helps regulate body temperature and pH levels.
