blood volume
Total circulating fluid
Blood volume is the total amount of blood circulating in the body at any given time.
In adults, this is typically about five liters.
Medical contexts track blood volume to assess hydration, blood loss, or conditions affecting circulation: The patient's blood volume dropped dangerously after surgery.
Athletes may train at altitude to increase blood volume.
