What is vasoconstiction?
vasoconstriction is when your blood vessels contract.
Does heat therapy cause vasoconstriction?
Yes
Is it true that the increased cooling that a wind can cause is called the Coriolis effect?
No. The Coriolis effect is the deflection of wind and ocean currents caused by Earth's rotation. The increased cooling from wind is called wind chill.
What is the effect of increasing the number of coil of wire wrapped around the core of an electromagnet?
This causes the power of the electromagnet to be increased.
What is the effect of increasing the number of coils of wire wrapped around the core of an electromagnet?
This causes the power of the electromagnet to be increased.
Does an increased afterload reduce the heart's ejection fraction?
Yes
What effect does Sodium Nitroprusside have on afterload and preload?
It decreases preload and afterload as a result of the dilation in the venous and arterial vasculature from the nitric oxide.
What is effect of adrenallin in anaphylactic shock?
by vasoconstriction and opening of the airway
Do angiotensin II blockers affect preload or afterload?
Afterload
What are signs of nervousness?
- increased sweating - cold, pale skin (due to vasoconstriction) - pupillary dilation - jitteriness (muscular innervation) - increased heart rate - increased blood pressure
In a healthy individual which of the following would be low Contractility Preload Stroke volume or Afterload.?
afterload
What vessels provides right and left ventricular afterload?
The aorta and the pulmonary arteries provide right and left ventricular afterload. Afterload is the resistance the blood loaded into the heart when it tries to leave.
How does vasoconstriction and vasodilation of blood vessels effect blood pressure?
No. Vasoconstriction is a squeezing of the veins. This is like putting your thumb at the end of a garden hose. The constriction of the flow increases the pressure. The water shoots out faster from the hose when your thumb is blocking the way. If the entire hose were to tighten, as in vasoconstriction, the same effect happens.--From Wikipedia: Vasoconstriction"Generalized vasoconstriction usually results in an increase in systemic blood pressure..."
Dose morphine increase or decrease afterload?
Morphine decrease cathecolamines therefore decreases afterload.
Which industry was helped the most by increased immigration from China?
Increased Immigration from China had a significant effect on railroads.
What is afterload?
Afterload is the tension or stress developed in the wall of theleft ventricleduring ejection. In other words, it is the endLoadagainst which the heart contracts to eject blood.
When does vasoconstriction take place?
Vasoconstriction typically occurs in response to various stimuli such as cold temperatures, stress, or the release of certain hormones like adrenaline. It causes the blood vessels to narrow, leading to increased blood pressure and reduced blood flow to certain areas of the body.
