Quick Answer: What Are The Three Main Factors Affecting Blood Pressure?

What are the two main determinants of blood pressure?

The two determinants of arterial blood pressure are the volume of renal output and the amount of salt and water in the system..

Does body size affect blood pressure?

In general, studies have reported a strong linear relationship between height and blood pressure and between body mass and blood pressure such that tracking correlations from childhood to adulthood for both blood pressure and body mass index are significant for most sex and ethnic groups.

What are the factors affecting blood pressure?

Risk Factors for High Blood Pressure (Hypertension)Being overweight or obese. The more you weigh the more blood flow you need to supply oxygen and nutrients to your tissues. … Too much salt (sodium) in your diet. … Too little potassium in your diet. … Not being physically active. … Drinking too much alcohol.

What are three factors that affect blood flow?

Variables Affecting Blood Flow and Blood PressureCardiac output.Compliance.Volume of the blood.Viscosity of the blood.Blood vessel length and diameter.

What are 5 factors that affect blood pressure?

Five factors influence blood pressure:Cardiac output.Peripheral vascular resistance.Volume of circulating blood.Viscosity of blood.Elasticity of vessels walls.

What time of day is blood pressure lowest?

Blood pressure is normally lower at night while you’re sleeping. Your blood pressure starts to rise a few hours before you wake up. Your blood pressure continues to rise during the day, usually peaking in the middle of the afternoon. Then in the late afternoon and evening, your blood pressure begins dropping again.

What are the two major factors affecting blood flow rates?

What are two major factors affecting blood flow rates?…To increase pressure and reduce resistance.To equalize the blood flow with the pressure differences.To maintain adequate blood flow through peripheral tissues and organs.To equalize the stroke volume with the cardiac output.

What are the 4 main factors that influence blood pressure?

What are the 4 main factors affecting blood pressure? Peripheral resistance, Vessel elasticity, Blood volume and cardiac output. Blood cells and plasma encounter resistance when they contact blood vessel walls.

Where is blood flow the fastest?

This value is inversely related to the total cross-sectional area of the blood vessel and also differs per cross-section, because in normal condition the blood flow has laminar characteristics. For this reason, the blood flow velocity is the fastest in the middle of the vessel and slowest at the vessel wall.

What increases blood flow?

What has the greatest effect on blood pressure?

Increases in peripheral resistance, blood volume, and cardiac output result in higher blood pressure. Conversely decreases in any of these factors lead to lower blood pressure. Three main sources of peripheral resistance: Blood vessel diameter, blood viscosity, and total vessel length.
