👉 The "big fluid" in this context refers to blood, the circulatory fluid that plays a crucial role in transporting essential substances throughout the body. Composed primarily of water, proteins, electrolytes, nutrients, hormones, and waste products, blood serves multiple vital functions. It carries oxygen and nutrients to tissues and organs, removes carbon dioxide and other waste products, regulates body temperature, and supports the immune system by transporting white blood cells. Blood also plays a key role in clotting to prevent excessive bleeding and maintaining pH balance. This complex fluid is produced by the bone marrow and circulates through a vast network of blood vessels, ensuring that every cell receives the necessary resources for optimal function.
