Health & Medicine on Khan Academy: No organ quite symbolizes love like the heart. One reason may be that your heart helps you live, by moving ~5 liters (1.3 gallons) of blood through almost 100,000 kilometers (62,000 miles) of blood vessels every single minute! It has to do this all day, everyday, without ever taking a vacation! Now that is true love. Learn about how the heart works, how blood flows through the heart, where the blood goes after it leaves the heart, and what your heart is doing when it makes the sound “Lub Dub.”

Thank you for this video! For those who questioned why the word "Serum" was used, Fibrinogen is used for blood clot. Therefore, "serum" contains substances that are left after blood clot and is used for variety of diagnostic procedures.

When using a refractometer you use the serum and plasma tp levels to get the fibrinogen. But you said the serum doesnt contain fibrinogen? Is it that the tp from the plasma figure minus the serum represents the content which is fibrinogen?

Great video, but one minor problem. The color of the tube is actually lavender, not green. This may seem insignificant initially, but the color of the tubes correlate with different additives that are not only used to prevent clotting, but also to preserve the analyte trying to be measured. The color you used in the video would not be a hematology specimen, but most likely a chemistry. In reality if a tube was sent down to the lab in a mint green/green tube this would not be accurate, the specimen would be rejected and require a recollect.

@scott1234567 9 жыл бұрын

A green coloured tube will be for chemistry and contains lithium heparin usually used for getting a clearer result on K levels. Also you do have blue topped samples used in haematology for coagulation tests which will be spun down and contain tri sodium citrate as an anti coagulant so you end up with plasma to run tests on fibrinogen etc.

according to my textbook, it states that it has wastes. What kind of wastes does it have? and plus, if there is waste, how can it provide nutrients to the cells since wastes and nutrients are mixed into that same liquid concentration.
