Why is my resistance so low?
She said that after I get over this most recent bout of illness, she is going to send me for blood tests to see why my resistance is so low.
What can high voltage do to you?
The really dangerous thing is how many electrons per second travel in the human body and this is the current. So the current is the "dangerous" part, and, as i remember correctly,if you stick(similar to electrolysis where your blood acts as an electrolyte ,here current is directly set up in the electrolyte) 2 electrode needles in your body, a 9V battery is sufficient to electrocute you (because the resistance of the electrolyte in the blood is really low and so the current is high), but if you don't stick(just touching the too needles with hand etc etc..) anything in your body but only touch two wires, the tissue resistance is high enough and the 9V battery is harmless.
Why are blood smears made with a feathered edge?
When a patient needs certain blood work done for testing of potential conditions, one way of testing the blood is by doing a blood smear. A blood smear is done by doing a finger prick, extracting a drop of blood, and placing the drop of blood on a glass laboratory microscope plate. Once the drop of blood is on the glass plate, a separate glass plate is used to spread the drop of blood out. It is done by "smearing" the blood across the bottom plate. The desired and only lab-accepted "smear" results in a feathering of the blood, or a increasingly thinning of the amount of blood across the plate, in turn creating a feathered appearance of the blood on the plate. It helps the lab chemists look at the right amount of blood for determining the results of the blood test.
Why is a stent used?
A stent is used when blood vessels are clogged (for example, because of a plaque that has grown on the vessel wall. This obstructs the flow of blood, which can have negative consequences for the tissues that are supplied with nutrients by the blood vessel in question. To improve the flow of blood, a stent can be deployed in the blood vessel at the place of obstruction. A stent will basically push the blood vessel open from inside.
Which vessels have valves?
capillary blood sugar vs venous blood sdugar
Would vasoconstriction decrease peripheral resistance?
No, vasoconstriction would increase peripheral resistance. When blood vessels constrict, the diameter of the blood vessels becomes smaller, which increases resistance to blood flow. This can lead to an increase in blood pressure.
What are the factors affecting peripheral resistance which influence BP?
There are three factors that increase peripheral resistance. These factors include autonomic activity, pharmacologic agents, and blood viscosity. Each factor increases the constriction of arteries, which in turn causes peripheral resistance.
Name two factors that increase peripheral resistance?
Peripheral resistance can be increased by an increase in blood volume and the constricting of blood vessels.
How does blood viscosity affect blood flow?
Peripheral resistance
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.
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.
A resistance to blood flow due to friction between blood and blood vessel walls is called what?
it is called peripheral resistance.
What decreases peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
What are the main factors that contribute to total peripheral resistance?
Total peripheral resistance is mainly influenced by the diameter of the blood vessels, vessel length, blood viscosity, and the compliance of the vessel walls. Vasoconstriction and vasodilation also play a significant role in regulating total peripheral resistance. Additionally, factors such as arterial blood pressure and neural and hormonal control can impact total peripheral resistance.
What is the relationship between peripheral resistance and blood pressure?
Systolic BP is a measure of blood pressure while the heart is pumping; diastolic BP is a measure of blood pressure while the heart is not pumping. BP is the pressure of the blood on the walls of the blood vessels.
What would decreased peripheral resistance to blood flow?
Vasodilation and decreasing blood viscosity
What are the factors related to blood pressure?
Peripheral resistance and cardiac output
