What is the normal blood pressure gradient in pulmonary capillaries?
923147
Strange question the way it's worded.  Capillary pressure isn't measured.  I don't know what you mean by "gradient".  Pulmonary artery pressure is, however, measured and the norm is 14mmHg at rest.  If it is >25 at rest and >30 with exercise, it's considered pulmonary hypertension.  Is this what you really wanted to know?

Sounds like a job for Wikipedia!\n\nBlood pressure is the pressure of the blood on the walls of the blood vessels as the heart squirts it through the circulatory system.   When your blood first leaves the pump (your heart) it's moving as fast as it's going to, and there's as much pressure in the system as there's going to be.  The farther from the heart you go, the less the pressure in the system (just like an irrigation system, or the plumbing in a house.)\n\nThe heart not only has to pump the blood out to where it's needed, it has to pump it back again, to run it through the lungs to pick up some more oxygen so it can be recirculated.  Blood pressure is much lower on the return trip, when the blood is way out there far from the pump.  The outbound system is your arteries, the return trip is your veins.  \n\nMostly when you measure blood pressure, it's the pressure in the big arteries that are close to the skin and easy to find without poking any holes (the brachial artery in the arm is an example). \n\nThe traditional way to measure blood pressure is in millimetres of mercury (mm Hg), and you always state it the same way so everyone knows what you're talking about.  From a medical point of view what you're interested in is how much pressure there is in the system when the heart isn't squirting new blood into it (at the "resting" phase or "bottom" of the heartbeat cycle) which is called the diastolic pressure; and then how much pressure there is in the system at the top of the cycle, when your heart is forcing new blood into your arteries, which is called the systolic pressure.  So the "top of the cycle" number goes on top, and the "bottom of the cycle" number goes on the bottom.  A typical reading for a resting, healthy adult is around 120/80 (meaning 120 mmHg systolic and 80 mmHg diastolic)\n\nHope this is what you needed!

Arteries carry blood AWAY from the heart.  The name has nothing to do with the O2 content of the blood in the vessel, so pulmonary arteries are carring blood away from the heart to the lungs where it can get oxygenated.  Veins carry blood back to the heart.  In the case of pulmonary veins, they are carring oxygenated blood TO the heart so that the heart can pump it out to the rest of the body.  The answer is B. pulmonary veins.

Yes, this is a good blood pressure.  normal range is between 100/60 and 120/80 approximately.  The top number is the pressure when the heart is squeezed during a beat and all the blood is in the vessels.  The bottom number is the pressure when the heart is relaxed during a beat and blood fills the heart, so less is in the vessels.

This something would be aortic artery pressue (reflecting systemic circulation) is equal to pulmonary artery pressure and this would happen in pulmonary hypertension. Yet, in pulmonary hypertension, closure of the pulmonic valve would be rather delayed than increase in intensity.

120/80mm.hg. is the normal blood pressure.Stress,tension,anxiety,heavy smoking and alcohol normally increase the blood pressure.140/90mm hg. is temporarily acceptable and if the cause is removed,cure is guaranteed.In the absence of any cause B.P. .140/90 hints at a disease of Thyroid or Kidney.Get a full check up.

Your depth of breathing and rate of breathing is adjusted by your body to keep your arterial blood oxygen saturation level about 95+% (this can be checked with a simple oximeter) and the arterial carbon dioxide at 40 mm Hg (this usually requires an arterial blood sample to check).

normal pulse pressure is 40, ie.systolic blood pressure minus diostolic blood pressure.

With the average heart rate of 72 beats per minute the heart will pump about 5 litres per ventricle, or about 10 litres total per minute. This is called the cardiac output. In a trained athlete the total cardiac output is about 20 litres. If we multiply the normal, non-athlete output by the average age of 70 years, we see that the cardiac output of the average human heart over a life time would be about 1 million litres, or about 250,000 gallons(US)!

Check out Wikipedia's article on it.  It's at:\nhttp://en.wikipedia.org/wiki/Jugular_venous_pressure

Normal range of Systolic blood preasure 100-139 mmHg\n\nNormal range of diastolic blood pressure 60-90 mmHg\n\nNormal Pulse Pressure (difference between both)= 30-50 mmHg\n\nanything close to the maximum is called high normal nad should keep checking regularly because he is high liability of becoming hypertensive. however, there's nothing called low normal.Hypotension is only feared when any of diastolic or systolic pressure is below the above stated number\n\nso you r just fine

You can't determine a blood pressure by counting a pulse.  You need a blood pressure cuff.  You can approximate a blood pressure depending on where you feel the pulse.  If you feel a strong radial pulse (the pulse in the wrist) the pressure is usually at least 80 mmHg systolic or above.  If you can't feel it in the wrist but you can feel it in the groin it is usually around 70 mmHg systolic.  If you can only feel a pulse in the carotid artery (the pulse in the neck) the blood pressure is around 60 mmHg systolic.  The systolic pressure is the peak pressure in the arteries in the cardiac cycle.  This is the top number in a blood pressure.  Normal blood pressure is 120/70, however normal is usually higher or lower for most people.

Systolic is the top number in your blood pressure.  It represents the pressure against arterial walls when the heart is contracted.  The diastolic pressure represents the pressure against the arterial walls when the heart is relaxed, or at the beginning of a cardiac cycle.  What affects vasoconstriction or vasodilation are neurotransmitters.  These occur naturally in your body, but have been replicated for medical use.  Vasodilation is when your vascular system, or your veins, open up.  (A good example of this is Nitro Glycerine.) With more space, there is less pressure.  Vasoconstriction is when the vascular system constricts, (A good example of a vasoconstrictor is dopamine.) so less space, more pressure. With lower pressure, the heart thinks it has to work harder to fill the "container", (container being your vascular system.) so it increases its rate to compensate.  Higher pressure means the heart is having to work harder to get the liquid (blood) where it needs to go.  Picture a pump system.  You need a pump, (your heart) a container (vascular system) and liquid volume. (Blood.)  THe point would be to keep the container filled, volume circulating, and the pump working.  \n     Hope that clears it up for you a bit!

end diastolic volume is typically 120mL/beat and end systolic volume is aproximately 50mL/beat

The normal resting heartrate varies due to many things but the normal range for an adult is considered to be 60 to 100.
