What criteria does blood flow depend on?
Blood flow depends on various physiological factors, including blood vessel diameter, blood viscosity, and blood pressure. Additionally, factors such as cardiac output, peripheral resistance, and overall vascular health can influence blood flow in the body.
What factors influence resistance to blood flow?
Factors that influence resistance to blood flow include the diameter of blood vessels (smaller diameter increases resistance), length of the vessels (longer vessels increase resistance), blood viscosity (thicker blood increases resistance), and turbulence within the blood vessels (increased turbulence increases resistance).
What factors influence dermal blood flow?
Body tempature, if your frightened or nervous, respitory/ circulation disorder
What factors directly influence venous blood flow?
Factors that directly influence venous blood flow include venous pressure, intrathoracic pressure changes during respiration, skeletal muscle contractions, venous valves, and sympathetic nervous system activity. These factors help propel blood back to the heart against gravity.
What two factors that influence the viscosity of lava flow?
Minerology of the area
What are two factors that influence the viscosity of lava flow?
Minerology of the area
What are the three major circuits of the blood?
Systemic circuit- blood flow in the body Coronary circuit- blood flow in the heart Pulmonary circuit - blood flow in the lungs
What is blood flow directly proportional to?
Blood flow is directly proportional to blood pressure, vessel diameter, and heart rate. When these factors increase, blood flow also increases, and vice versa.
Other factors that prevent retrogade blood flow?
Valves
What factors influences resistance to blood flow in the arteries?
resistance occurs as the blood flows away from heart through the vessels in the peripheral systemic circulation a term known as peripheral resistance. Viscosity of the blood (thickness) ,vessel length (distance) and vessel diameter (blood vessel radius) are three factors
How is coronary blood flow regulated?
Coronary blood flow is regulated by local metabolic factors. Adenosine, nitric oxide, and decreased oxygen all act as vasodilators which improve blood flow in coronary circulation.
What influence does the cerebral cortex have on blood flow?
Not much, your brain has little to do with your heart rate
