How do ace inhibitors help in chf?
ACE inhibitors block angiotensin, a natural vasoconstrictor, this in turn allows blood vessels to relax and thereby reduce the blood pressure. When blood pressure is reduced in heart failure this helps to lower the workload of the failing heart. In other words, the failing heart does not have to pump against a high pressure (imagine taking a water hose and clamping it, very little water comes through the end and you can feel the pressure building up- this is what happens when blood pressure is high and a failing heart's left ventricle has to pump the blood out to the body). This is how I explain it to my students. Hope this helps A RN educator in NJ
What pumps blood into the heart?
The right ventricle pumps blood into the pulmonary artery.
When you cut an artery blood spurts out Why?
Because arteries are blood vessels that carry blood away from the heart. There are many arteries that carry blood to all parts of the body. And how dangerous a severed artery is depends on how deep the cut is and what artery is cut.
What isblood pressure?
The systolic blood pressure is a measure of the pressure exerted on the inside of the blood vessels when your heartmuscle is contracting and pumping blood. This is the maximum pressure in the blood vessels. The diastolic blood pressure is the pressure between heart beats when the heart is resting and filling with blood. This is the minimum pressure in the blood vessels.
Which hormone released by the heart regulates blood pressure?
Anti Naturetic Hormone which functions in reduction of water in the body.
How does water effect congestive heart failure?
increase in water will increase the blood pressure. high blood pressure usually precipitate the heart failure. Congestive heart failure on the other hand usually start with left ventricular failure and finally also cause the right ventricular failure. Patient will congestive heart failure usually will be given diuretic medication to remove excess water in their blood.
Effect of facial immersion in cold water on heart rate and blood pressure?
the heart rate decreases, to a low rate oof 20 to 30 beats per minute. especially in cold water.
What organs maintain blood pressure?
From eurekalert:When blood pressure increases the kidneys respond by extracting extra water and salts into the urine, causing blood volume -- and hence pressure -- to fall. But special nerve pathways mean the brain can also regulate urine production and hence influence blood pressure.So, no one organ regulates blood pressure.
How does blood pressure make blood move though the various regions of the cardiovascular system?
Blood pressure is the actual pressure of blood traveling in the arteries of the body. Blood pressure is caused by the force of a pump (the heart) pumping blood into the arteries which have tight walls. The pressure of the blood results in the blood circulating just as water pressure will result in water circulating to any pipes attached to a water pump. When a person has very low blood pressure the blood does not circulate much and the person is said to be "in shock." When a person has no blood pressure the blood does not circulate at all and the person is dead.
What effect does the presence of ANP have on the body?
It lowers blood pressure by increasing the excretion of sodium and water.
Would increased water retention lead to increased blood pressure?
It will absolutely raise your blood pressure because sodium constricts veins & vessels your heart needs to use more pressure to force blood flow.

What effect do you think that has no air pressure on the ground?
Without atmospheric pressure, water will boil to vapour, so as our blood and body would explode. Pressure is what that keep water in liquid and solid state on earth.
How does bloodshot in the eye happen?
A blood shot can happen in many ways from the pressure of wind, poor water (chlorine) can effect they eye with its layer and cause blood around the effect area.
What pumps blood into the heart?
The right ventricle pumps blood into the pulmonary artery.
What does a doctor mean when she tells a patient with high blood pressure that water is the best diuretic?
A Diuretic is just a substance that makes a person pee a lot. so the doctor just means drinking water is the best way to make someone pee more. im not sure what it has to do with high blood pressure though ---- For high blood pressure, diuretics, commonly known as "water pills," help your body get rid of unneeded water and salt through the urine. Getting rid of excess salt and fluid helps lower blood pressure and can make it easier for your heart to pump. Diuretics may be used to treat a number of heart-related conditions, including high blood pressure, heart failure, kidney and liver problems, and glaucoma. -Levi
How would decreasing the amount of water in the blood affect blood pressure?
Blood pressure would decrease
