What is the pressure of blood against the blood vessel walls?

What is the pressure of blood against the blood vessel walls?

Blood pressure (BP) is the pressure exerted by blood on the walls of a blood vessel that helps to push blood through the body. Systolic blood pressure measures the amount of pressure that blood exerts on vessels while the heart is beating. The optimal systolic blood pressure is 120 mmHg.

What is used to measure the pressure exerted on the walls of the blood vessels during refilling of the heart?

… two pressures measured: (1) the systolic pressure (the higher pressure and the first number recorded), which is the force that blood exerts on the artery walls as the heart contracts to pump the blood to the peripheral organs and tissues, and (2) the diastolic pressure (the lower pressure and the…

How does the body make blood pressure?

The force is generated with each heartbeat as blood is pumped from the heart into the blood vessels. The size and elasticity of the artery walls also affect blood pressure. Each time the heart beats (contracts and relaxes), pressure is created inside the arteries.

Which disease is described when the pressure of the blood against the wall of blood vessel is high?

Abnormally high blood pressure, when sustained above healthy levels at rest, is known as hypertension; when blood pressure remains below normal levels, the condition is called hypotension.

What health problems are associated with high blood pressure?

Uncontrolled high blood pressure can lead to complications including:

  • Heart attack or stroke.
  • Aneurysm.
  • Heart failure.
  • Weakened and narrowed blood vessels in your kidneys.
  • Thickened, narrowed or torn blood vessels in the eyes.
  • Metabolic syndrome.
  • Trouble with memory or understanding.
  • Dementia.

What happens in the body when blood pressure is high?

High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause: Chest pain, also called angina.

What happens to blood vessels when blood pressure increases?

High blood pressure causes thickening of the walls of blood vessels and also makes them more likely to develop hardening of the arteries (atherosclerosis ). People with thickened blood vessel walls and atherosclerosis are at higher risk of stroke, heart attack, vascular dementia, and kidney failure.
