👉 The bigger fluid, often referred to as blood, is a complex and vital component of the human body, primarily composed of water but also containing various cells, proteins, nutrients, hormones, and waste products. It serves as the primary medium for transporting oxygen, nutrients, hormones, and immune cells throughout the body while also playing a crucial role in removing waste products like carbon dioxide. Blood is produced by the bone marrow and circulates through a vast network of blood vessels, ensuring that every cell receives the necessary sustenance and remains protected from harmful substances. Its dynamic nature allows it to adapt to the body's changing needs, making it indispensable for maintaining overall health and homeostasis.
