What is the relationship between air pressure and blood pressure?
Interestingly, according to the Bernoulli principle, when air flow is increased, air pressure is actually decreased! This same principle can be applied to any sort of fluid flow, though it the main principle applies only to a nonconducting fluid and an inviscid flow.
What is done by calcium channel blockers?
Calcium channel blockers block the entry of calcium into muscle cells in artery walls. Muscle cells need calcium to constrict, so reducing their calcium keeps them more relaxed and lowers blood pressure.
Which body system would be most affected by a lower than normal atmospheric pressure?
The respiratory system would be most affected by a lower than normal atmospheric pressure. Decreased atmospheric pressure can lead to reduced oxygen levels in the blood, which can impact lung function and overall respiratory health.
What is a dihydropyridine calcium channel blocker?
A dihydropyridine calcium channel blocker is a type of medication that works by blocking calcium channels in blood vessels and the heart. This leads to relaxation of blood vessels, reduced heart workload, and decreased blood pressure. Examples include amlodipine and nifedipine.
Are veins under high pressure?
No, veins are not under high pressure. High-pressure vessels are the arteries.
Why does a person with diabetes need to watch their blood pressure?
If you are a diabetic, you should monitor your blood pressure because you are at a higher risk for developing hypertension and heart disease. Diabetes predisposes one to atherosclerosis which can lead to many severe medical problems, even death.
What happens to filtrate volume when systemic blood pressure is decreased?
Filtrate volume decreases when systemic blood pressure decreases.
How do you Explain the underlying cause of the Korotkoff Sounds that you detected with the Cardio Microphone as the cuff pressure was decreased?
When the blood pressure cuff is inflated, the blood flow is stopped. Slowly the cuff is decreased. When the technician starts to hear the blood flow, these are called Korotkoff Sounds. This pressure point defines the systolic pressure.
What is the difference between vasodilate and vasoconstrict?
Vasodilation is the widening of blood vessels, resulting in increased blood flow and decreased blood pressure. Vasoconstriction is the narrowing of blood vessels, leading to decreased blood flow and increased blood pressure. Both play important roles in regulating blood flow and maintaining homeostasis in the body.
What would happen to blood volume and blood pressure if water and salts were not reabsorbed?
since there were no enough water and salts reabsored, there woulnd't be enough blood volume, and blood pressure will be decreased.
What is hypoadrenalism?
Decreased production of the adrenal gland, which can result in low blood pressure and hypoglycemia (low blood sugar).
Do panic attacks cause your eyes to turn red?
Yes In panic attacks eveys will not turn red why because when a person get panic the herat rate will increase so that the blood pressure will comedown.when there is decrese in blood flow,even there is decreased bloodflow in the eyes.

Decreased peripheral resistance to blood flow?
Decreased peripheral resistance to blood flow is typically associated with vasodilation, which occurs when the smooth muscle in blood vessel walls relaxes. This can lead to increased blood flow to tissues and decreased blood pressure. Vasodilation can be caused by factors such as the release of nitric oxide or certain medications.
Sympathetic division stimulation causes?
Increased blood glucose, decreased GI peristalsis, and increased heart rate and blood pressure.
How do diurnal variations affect blood pressure?
Fluctuations in an individual's blood pressure are normal during the course of a day. When one awakens, the blood pressure is lower as a result of the decreased metabolism and physical activity during sleep. As metabolism and activity increases during the day, the blood pressure rises.
Decreased temperature helps to facilitate increases in ROM?
Blood pressure is the force exerted by the blood against the inner walls of the blood vessels
Blood pressure may be reduced with the use of what agent that enlarges the lumen of blood vessels?
Blood pressure may be reduced with the use of vasodilators, which work by relaxing and enlarging the lumen of blood vessels, leading to decreased resistance and improved blood flow. This can help in lowering blood pressure by reducing the workload on the heart.
