Lesson 6 - Blood Pressure And Delivery Flashcards
What is blood pressure?
Blood pressure is the amount of force applied to a given area of a blood vessel wall as the blood flows past it.
What is the difference in pressure during systole and diastole?
Systole - Blood is being pumped out and pressure is higher.
Diastole - Heart is relaxing and pressure is low.
What does a greater area result in?
A greater area results in less pressure.
What are medical professionals listening for when a blood pressure meter is being used?
Arteries don’t normally have sounds, but the medical professionals are listening for sounds every time the heart generates enough force to open the vessel on the other side. This will occur when the cuff of the blood pressure monitor becomes tighter using the pressure control valve/pump.
What do valves prevent?
Valves prevent the blood from moving back into the previous section and going back down.
Why should you avoid exercising immediately after eating?
If you want to send blood down to your legs, you will need to dilate your iliac arteries and decrease the amount of blood being sent to the digestive system. This is why you should not exercise immediately after eating.
