What is blood pressure?
Blood pressure is the amount of force that your blood puts on your artery walls as it moves through your body. Arteries are blood vessels that carry blood from your heart to the rest of your body. When your heart beats, it pushes your blood through your arteries. As the blood moves, it puts pressure on your artery walls. This is called your blood pressure.
What is high blood pressure?
High blood pressure (also called hypertension) occurs when your blood moves through your arteries at a higher pressure than normal. Many different things can cause high blood pressure. If your blood pressure gets too high or stays high for a long time, it can cause health problems.
