👉 The fluid, or blood, is a complex mixture of cells and substances that circulates through the body's vascular system. Primarily composed of water, it carries essential nutrients, oxygen, and hormones to cells while removing waste products like carbon dioxide. This vital fluid also plays a crucial role in immune defense, clotting blood to prevent excessive bleeding, and regulating body temperature. Its composition changes slightly depending on the specific type of fluid (like plasma or blood cells), but its core function remains the transport and delivery of vital substances throughout the body, making it indispensable for maintaining homeostasis and overall health.
