How will blood peripheral resistance change as a result of increased hematocrit?

∙ 15y ago
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 change would you expect to happen in the hematocrit of a person who is dehydrated?
Hematocrit is a measure of the % of blood occupied by the Red Blood Cells (RBC) which carry oxygen. In the short term the hematocrit is affected by the % of water in the body, so if the person becomes dehydrated there is relatively less water than cells, so the haematocrit goes up.
What makes an ecosystem stable?
Having a diversity of species and having resistance towards change
Why are the arterioles known as resistance vessels?
A. They distribute blood to various parts of the body. B. They contain a large quantity of elastic tissue. C. The contraction and relaxation of the smooth muscle in their walls can change their diameter. D. Their prime function is the exchange of nutrients and wastes between the blood and tissue cells.
What is Herbicide resistance?
For a herbicide to kill a plant, the herbicide needs to be absorbed by the plant, be moved to its site of action while remaining intact and inhibit its target enzyme. Herbicide resistance in weeds occurs as a result of changes that prevent the herbicide from effectively inhibiting the target. While resistance could be the result of a change that affects any one of the processes described above, in practice three types of resistance mechanism are observed.
What is the scientific meaning of ineria?
Going to guess you meant to say Inertia. Inertia is the resistance of any physical object to a change in its state of motion or rest, or the tendency of an object to resist any change in its motion.
Does exercise Change in cardiac output or in peripheral resistance?
Both, peripheral resistance decreases and cardiac output increases.
How do blood pressure and total peripheral resistance change with exercise?
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
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 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.
Will the current of circuit change on changing the ammeter resistance?
The accuracy of ammeter changes as the resistance is increased or decreased.AnswerThe simple answer is yes, it will change. However, whether it will be a perceptible change is another question. Ammeters are designed to cause the minimum change to the actual circuit current when they are inserted into a circuit.
Why does the rate of movement of tectonic plates change?
The rate of movement of a lithospheric plate will change as the resistance in the path of convection is increased or decreased because of the types of convergent collisions.
If A conductor has a resistance of 0.8 ohms what will happen to its resistance if the temperature is increased?
The resistance of a conductor normally increases with temperature. The increase in resistance is due to charged particles becoming more agitated and the number of particles going across a potential field at a given time period will be reduced (like in a traffic jam, the car engines are running but the cars are not going faster). The change in resistance per degree temperature change for a metal can be measured and are published.
What is constant resistance?
A resistance that doesn't change.
What change would you expect to happen in the hematocrit of a person who is dehydrated?
Hematocrit is a measure of the % of blood occupied by the Red Blood Cells (RBC) which carry oxygen. In the short term the hematocrit is affected by the % of water in the body, so if the person becomes dehydrated there is relatively less water than cells, so the haematocrit goes up.
What is the percent change when 18 is increased to 45?
18 increased to 45 is a change of +150%
Does potential difference change with change in resistance?
Changing the potential difference in a circuit does not change the resistance. Rather, it changes the current.
If you double both the voltage and the resistance in a circuit what would be the effect on the current?
If you double the voltage in a circuit, the power is quadrupled, assuming the resistance stays the same.
