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.
How does the relationship between blood pressure, cardiac output, and peripheral resistance impact overall cardiovascular health?
The relationship between blood pressure, cardiac output, and peripheral resistance is crucial for overall cardiovascular health. Blood pressure is the force of blood against the walls of the arteries, which is influenced by cardiac output (the amount of blood pumped by the heart) and peripheral resistance (the resistance to blood flow in the blood vessels). When these factors are balanced, it helps maintain healthy blood pressure levels and proper blood flow throughout the body, supporting overall cardiovascular health. Imbalances in these factors can lead to conditions like hypertension or heart failure, which can negatively impact cardiovascular health.
Which Site is the major determinant of peripheral resistance?
Arterioles are the major determinant of peripheral resistance in the cardiovascular system. Their small diameter and ability to constrict or dilate play a key role in regulating blood flow and pressure in different parts of the body.
How do peripheral vasodilators work?
Peripheral vasodilators work by relaxing the smooth muscle in the walls of blood vessels, which causes them to dilate and widen. This leads to a decrease in resistance to blood flow, resulting in increased blood flow to the peripheral tissues. This can help reduce high blood pressure and improve circulation.
What are examples of evolutionary adaptation?
Examples of evolutionary adaptation include the development of camouflage to avoid predators, the evolution of a protective exoskeleton in insects, the elongation of giraffe necks to reach high leaves, and the development of antibiotic resistance in bacteria.
The client was admitted to the hospital with hypertension The development of arteriosclerosis has increased peripheral resistance to blood flow worsening his hypertension This is an example of what?
oh my gosh i hope someone answers this question soon, i am worried about that client.
The patient has arteriosclerosis which results in increased peripheral resistance to blood flow which worsens the hypertension Is this a negative or positive feedback.Explain?
Its a negative feedback,because the smaller the lumen , the higher the blood pressure because of the deposit in the vessel thus causing the resistance.
What is the explanation for the term total peripheral resistance?
Total peripheral resistance is the sum of the resistance of all peripheral vasculature in the systemic circulation.
What is main site of peripheral resistance?
arterioles offer maximum peripheral resistance .Skin and skeletal muscle blood vessels represent most imp. site of peripheral resistance.
What is periferal resistance?
Peripheral resistance refers to the resistance that blood encounters as it flows through the smaller blood vessels, primarily arterioles and capillaries, in the systemic circulation. It is influenced by factors such as the diameter of the blood vessels, blood viscosity, and the total length of the vascular system. Higher peripheral resistance can lead to increased blood pressure, while lower resistance facilitates easier blood flow. This concept is crucial in understanding cardiovascular health and conditions like hypertension.
Does exercise Change in cardiac output or in peripheral resistance?
Both, peripheral resistance decreases and cardiac output increases.
Name two factors that increase peripheral resistance?
Peripheral resistance can be increased by an increase in blood volume and the constricting of blood vessels.
Does dehydration increase peripheral resistance?
yes

What center in the medulla can alter peripheral resistance?
Hypothalamus

What is the event primarily responsible for peripheral resistance?
Constriction of arterioles
