The components of blood are carried around the body in a liquid medium. A patient has a blood test with the following results: Red blood cells count is 3.1times10123.1 \\times 10^{12}3.1times1012 per $\text{dm}^3$ (normal range is 4.0textto5.5times10124.0 \\text{ to } 5.5 \\times 10^{12}4.0textto5.5times1012), White blood cells count is 6.5times1096.5 \\times 10^96.5times109 per $\text{dm}^3$ (normal range is 4.0textto11.0times1094.0 \\text{ to } 11.0 \\times 10^94.0textto11.0times109), and Platelets count is 250times109250 \\times 10^9250times109 per $\text{dm}^3$ (normal range is 150textto400times109150 \\text{ to } 400 \\times 10^9150textto400times109).
Name the liquid part of the blood that transports these blood cells.
Identify which blood component of the patient is not within the normal range.
Suggest one symptom the patient might experience and explain how this is related to the function of the affected component.
