The Khan Academy

Solving for variables being multiplied by a fraction

Intuition behind why we multiply or divide both sides by the same value

Two worked examples of solving simple equations

Intro to our exercise available at: http://www.khanacademy.org/...

Figure out what systole and diastole mean and what happens in each heartbeat

Learn about Dr. Korotkoff's use of the stethoscope to listen for a blood pressure

Learn the categories of hypertension: Pre-Hypertension, Stage 1, and Stage 2

Learn about the relationship between resistance and the radius of a tube

Figure out how pressure relates to flow and resistance in the human body

Learn how to add up resistance in a series and in a parallel circuit

Learn the difference between salt and sodium and how much is acceptable in a low sodium diet

Take a guess as to which foods have the most salt and how you can begin a low sodium diet

Learn how to calculate your own body mass index

Learn the two types of hypertension and the common (or uncommon) symptoms

Learn about how hypertension can cause problems for your heart

Learn about the importance of improving your diet, losing weight, exercising, and quitting smoking

Learn the 11 major muscle groups in the body so you can be sure to exercise each one

Learn about the importance of stretching, aerobics, and resistance training

Find out what makes arteries and veins so different

Learn the layers of the artery, vein, and capillary

Learn the difference between arteriosclerosis, arteriolosclerosis, and atherosclerosis!

Try this problem of adding up resistance in parallel and in series

Learn about how blood pressure changes can occur as you get older, and the relationship between blood pressure and resistance

Learn about the effect of high blood pressure on the blood vessels

Find out how nerves in the blood vessels help to control the blood pressure

Learn about atherosclerosis and why it's bad for the blood vessels

Learn about atherosclerosis and why it's bad for the blood vessels
