Blood pressure 和 the circulatory system
Your tissues 和 organs need the blood your circulatory system carries through the body. Your heartbeat makes this happen by pushing blood through the blood vessels. These vessels include arteries, veins 和 capillaries.
Blood pressure is the result of two forces. The first force (systolic pressure) happens as blood pumps out of the heart 和 into the arteries. The second force (diastolic pressure) is created as the heart rests between heart beats. These two forces are each represented by numbers in a 血压读数.
The damage starts in your arteries 和 heart.

When blood pressure is high for too long, it can damage the walls of blood vessels, causing them to develop tiny tears. To fix these damaged areas, the body sends special cells that stick to the site. 随着沙巴足球体育平台的推移, substances such as cholesterol 和 fats may also build up at these damaged spots, 形成斑块.
As plaque slowly builds, a process called 动脉粥样硬化, it can make the inside of the arteries narrower. This narrowing can block the flow of blood, further increasing blood pressure.
