👉 The cycle fluid, also known as the circulatory or blood system, is a complex network of vessels and organs that transport vital substances throughout the body. It begins with the heart, which acts as a pump, propelling oxygen-rich blood from the lungs into the systemic circulation via arteries. This blood then delivers oxygen and nutrients to cells and organs before returning deoxygenated blood back to the heart through veins, eventually leading to the pulmonary circulation where it picks up carbon dioxide and other waste products. The cycle fluid also plays a crucial role in immune response, temperature regulation, and waste removal, ensuring that every cell receives the necessary resources for survival and function.
