What this chapter is about
The human body contains approximately 5 liters of blood continuously circulating through an extensive network of vessels. This blood serves as the primary transport medium, carrying oxygen from lungs to tissues, removing waste products, distributing nutrients and hormones, and maintaining temperature and pH balance. Beyond blood, the lymphatic system drains tissue fluid and returns it to circulation. Together, these transport systems enable the delivery of essential substances to all 37 trillion cells while removing metabolic waste products.
Understanding body fluids and circulation requires knowledge of:
