Cardiac output is the amount of blood pumped by the heart in one minute. It directly affects blood pressure because an increase in cardiac output leads to higher blood pressure, while a decrease in cardiac output results in lower blood pressure. This is because the more blood the heart pumps, the more pressure is exerted on the walls of the blood vessels.
When nicotine exerts its effect on the heart, the pulse rate of the smoker will increase while smoking the cigarette. A consequence of the pulse rate increasing is that the nicotine will raise the smoker's blood pressure.
Systolic BP is a measure of blood pressure while the heart is pumping; diastolic BP is a measure of blood pressure while the heart is not pumping. BP is the pressure of the blood on the walls of the blood vessels.
Blood pressure is the blood flow when the heart is pumping (top number) and when the heart is resting (bottom number). The body is a closed system and requires enough blood pressure to pump the blood throughout the body. A typically healthy blood pressure would be 120mmHg/70mmHg. Atmospheric pressure is the weight of the atmosphere at a specific location and altitude. At sea level, atmospheric pressure is 760mmHg. So actually, atmospheric pressure is much greater than blood pressure. Most people never have to worry about atmospheric pressure affecting blood pressure. However, deep sea divers experience an increase in blood pressure while diving, and astronauts experience a decrease in blood pressure when in space.
No. I think the systolic pressure is when ventricles constrict and the blood goes out , while the diastolic pressure is when ventricles relax and fill with blood.
No, that is incorrect. The term hypertension means high blood pressure. Hypotension means low blood pressure.
As with all blood pressure medicine the right diet and exercise will help keep your blood pressure under control.
is ok to take tamiflu with high blood pressure
The body regulates and controls blood pressure through a combination of mechanisms, including the nervous system, hormones, and the kidneys. The nervous system helps to adjust blood vessel size and heart rate, while hormones like adrenaline and aldosterone can increase or decrease blood pressure. The kidneys also play a role in regulating blood volume and pressure by adjusting the amount of water and salt in the body. These processes work together to maintain a stable blood pressure level.
when heart rate increases, blood pressure rises. When heart rate decreases, blood pressure drops. medications, and diseases affects the blood pressure. Source: About Blood Pressure
Blood pressure is generated by the force exerted by the heart pumping blood into the arteries and the resistance encountered by the blood flow in the arteries. The systolic pressure is the pressure when the heart contracts and pushes blood out, while the diastolic pressure is the pressure when the heart relaxes and refills with blood.
