The correct answer is: C. Artery.
Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood throughout the body. Arteries are the blood vessels that carry blood away from the heart.
The blood pressure reading is given as two numbers, such as 120/80. The first number, called the systolic pressure, is the pressure when the heart beats. The second number, called the diastolic pressure, is the pressure when the heart is at rest between beats.
Normal blood pressure is less than 120/80. High blood pressure is a condition in which the blood pressure is too high. High blood pressure can damage the arteries and lead to serious health problems, such as heart disease, stroke, and kidney disease.
There are several things you can do to lower your blood pressure, such as:
- Eat a healthy diet
- Exercise regularly
- Maintain a healthy weight
- Don’t smoke
- Limit your alcohol intake
- Take your blood pressure medication as prescribed by your doctor
If you have high blood pressure, it’s important to work with your doctor to manage your condition. With treatment, you can lower your risk of developing serious health problems.
Here is a brief explanation of each option:
- A. Heart: The heart is a muscle that pumps blood throughout the body. It is not a blood vessel, so it does not have walls that blood pressure can be exerted against.
- B. Vein: Veins are blood vessels that carry blood back to the heart. The pressure in veins is much lower than the pressure in arteries.
- C. Artery: Arteries are blood vessels that carry blood away from the heart. The pressure in arteries is much higher than the pressure in veins.
- D. Cell: Cells are the basic units of life. They do not have walls that blood pressure can be exerted against.
