血壓如何工作 – 威爾弗雷德·曼薩諾

Travel into the circulatory system to see how blood pressure helps deliver oxygen and nutrients to your body’s tissues.

—

If you lined up all the blood vessels in your body, they’d be 60 thousand miles long. And every day, they carry the equivalent of over two thousand gallons of blood to the body’s tissues. What effect does this pressure have on the walls of the blood vessels? Wilfred Manzano gives the facts on blood pressure.
