Explain. Blood pressure regulatory
Answers
Short-term regulation of blood pressure is controlled by the autonomic nervous system. Changes in blood pressure are detected by baroreceptors. These are located in the arch of the aorta and the carotid sinus. Increased arterial pressure stretches the wall of the blood vessel, triggering the baroreceptors.
Explanation:
Blood pressure often increases as weight increases. Being overweight also can cause disrupted breathing while you sleep (sleep apnea), which further raises your blood pressure.
Weight loss is one of the most effective lifestyle changes for controlling blood pressure. Losing even a small amount of weight if you're overweight or obese can help reduce your blood pressure. In general, you may reduce your blood pressure by about 1 millimeter of mercury (mm Hg) with each kilogram (about 2.2 pounds) of weight you lose.
Besides shedding pounds, you generally should also keep an eye on your waistline. Carrying too much weight around your waist can put you at greater risk of high blood pressure.
In general:
Men are at risk if their waist measurement is greater than 40 inches (102 centimeters).
Women are at risk if their waist measurement is greater than 35 inches (89 centimeters).
These numbers vary among ethnic groups. Ask your doctor about a healthy waist measurement for you.
2. Exercise regularly
Regular physical activity — such as 150 minutes a week, or about 30 minutes most days of the week — can lower your blood pressure by about 5 to 8 mm Hg if you have high blood pressure. It's important to be consistent because if you stop exercising, your blood pressure can rise again.
If you have elevated blood pressure, exercise can help you avoid developing hypertension. If you already have hypertension, regular physical activity can bring your blood pressure down to safer levels.
Some examples of aerobic exercise you may try to lower blood pressure include walking, jogging, cycling, swimming or dancing. You can also try high-intensity interval training, which involves alternating short bursts of intense activity with subsequent recovery periods of lighter activity. Strength training also can help reduce blood pressure. Aim to include strength training exercises at least two days a week. Talk to your doctor about developing an exercise program.
