👉 The CB fluid, or Central Blood Fluid, is a vital component of the circulatory system that plays a crucial role in maintaining homeostasis within the body. It primarily consists of plasma, red blood cells, white blood cells, and various other cellular elements and proteins. Unlike interstitial fluid, which fills the spaces between cells, CB fluid circulates through the vascular system, including arteries, veins, and capillaries, facilitating the transport of nutrients, oxygen, hormones, and waste products between tissues and organs. This fluid is essential for regulating blood pressure, immune response, and overall physiological balance, making it indispensable for the proper functioning of the body.
