total peripheral resistance will decrease because of vaso dilation of local arterioles that are supplying the active muscles i.e,skeletal muscles.
and blood pressure will increase for two reasons:
increased cardiac output resulting from increased pumping activity of heart.
because of vasoconstriction of arterioles every where else in the body
What else can I help you with?
Does exercise Change in cardiac output or in peripheral resistance?
Both, peripheral resistance decreases and cardiac output increases.
What is the site that is major determine peripheral resistance?
The major site that determines peripheral resistance is the arterioles. These small-diameter blood vessels can constrict or dilate to regulate blood flow and pressure throughout the circulatory system. Their ability to change diameter significantly influences total peripheral resistance, impacting overall cardiovascular function.
What causes peripheral resistance?
Peripheral resistance is the force against blood flow. In most cases, an increase in peripheral resistance would be caused by an increase in vasoconstriction, which would decrease blood flow. Other factors can influence vasoconstriction, such as circulating angiotensin II levels, cortisol levels, drugs such as cocaine and other adrenergic agonists, blood volume, atherosclerosis, emboli, renal diseases and increased intra-cranial pressure. An increase in blood pressure will also be caused by vasoconstriction and the mentioned factors.
How will blood pressure change after exercise?
After exercise, blood pressure typically increases due to the body's increased demand for oxygen and nutrients. This increase in blood pressure helps deliver more oxygen and nutrients to the muscles and organs that are working harder during exercise.
In the body what is the physiological cause of radii changes in blood vessels?
Vessel diameter can change quickly through casconconstruction or vasodilation. Most of the peripheral resistance occurs in arterioles (the small vessels of the arterial system). When these smooth muscles contract or relaz, peripheral resistance is either increased or decreased.Source: Modern Anatomy & Physiology by Ateegh Al-Arabi
What is vascular pressure that declines form 35 mm Hg to 18 mm Hg?
The change in vascular pressure is a decrease of 17 mm Hg (35 mm Hg - 18 mm Hg).
How will blood peripheral resistance change as a result of increased hematocrit?
An increased hematocrit indicates a higher ratio of RBC's in the blood. Any increase in cellular elements, whether WBC's, RBC's or platelets, will act to essentially mechanically "thicken" the blood viscosity, sort of like using a heavier grade oil in your car. Increased blood viscosity will increase peripheral resistance, as it becomes harder for the heart to circulate the thicker blood, especially in the capillaries.
What happens to blood pressure as you exercise?
Blood pressure increases during excercise because the heart rate increases to allow more blood to get to the working muscles. However: Moderate exercise, i.e. walking, has benefits for people suffering high blood pressure. Research has shown that walking several times a week for at least half an hour can help lower high blood pressure. It is best to avoid continued strenuous exercise, however - high BP causes greater strain on the arteries, and in strenuous exercise, one is making one's heart work harder.
How does an oil pressure gauge works?
Most oil pressure gauges operate by a varying voltage. The oil pressure changes the resistance in the oil sensor, causing the gauge to change readings.
What are the changes in systolic and diastolic blood pressure during exercise?
During exercise, systolic blood pressure typically increases due to the increased demand for oxygen by the muscles. Diastolic blood pressure may either stay the same or slightly decrease, as the blood vessels dilate to allow more blood flow to the muscles.
Does the viscosity of water change with pressure?
Yes, the viscosity of water decreases with increasing pressure. This is because pressure increases the energy of water molecules, allowing them to move more freely and reduce the resistance to flow, thus lowering viscosity.
Why artery called resistance vessels?
The contraction and relaxation of the smooth muscle in their walls can change their diameter, thus changing the level of pressure (large diameter yields low pressure and smaller diameter yields high pressure).
