Admin What would happen if the right side of the heart pump faster than the left side quizlet?
If the viscosity of blood were to increase, what could you do to keep the flow rate “normal”? What would occur if the left side of the heart pumped faster than the right side? Blood would soon empty from the heart, and stroke volume would fall greatly. What do the valves in the Pump Mechanics screen do?
What could cause an increase in the peripheral resistance in a blood vessel?
Peripheral resistance is determined by three factors: Autonomic activity: sympathetic activity constricts peripheral arteries. Pharmacologic agents: vasoconstrictor drugs increase resistance while vasodilator drugs decrease it. Blood viscosity: increased viscosity increases resistance.
What is the difference between the right side of the heart and the left side?
The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where the blood picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.
Which of the following vessels has the largest effect on total peripheral resistance?
Arterioles have the most increase in resistance and cause the largest decrease in blood pressure. The constriction of arterioles increases resistance, which causes a decrease in blood flow to downstream capillaries and a larger decrease in blood pressure.
Which has the greatest effect on peripheral resistance?
Radius of the arterioles is the most important factor, affecting vascular resistance, and it is regulated by systemic and local factors: Systemic factors include: Arterial baroreflex control (increased BP leads to a decrease in SVR. Peripheral and central chemoreceptors (hypoxia leads to increased SVR)
How does the plot differ from the plots for tube radius viscosity?
How does the plot differ from the plots for tube radius, viscosity, and tube length? Its directly related relationship, as the pressure increases flow will also increase. As viscosity increases then flow will decrease and if length of vessel increases flow decreases, if radius increase flow increases as well.
What is the total volume of blood that circulates around the body of a healthy person?
Adults: The average adult weighing 150 to 180 pounds should have about 1.2 to 1.5 gallons of blood in their body. This is about 4,500 to 5,700 mL.
What does increased peripheral resistance mean?
back | nextPeripheral Resistance Peripheral resistance is the resistance of the arteries to blood flow. As the arteries constrict, the resistance increases and as they dilate, resistance decreases. Blood viscosity: increased viscosity increases resistance.
