Re: Anatomy and Physiology B/C
i forgot to mention something else, frank starling law is different from starling's forces on capillaries.donutsandcupcakes wrote:Thanks, I appreciate it.bp31000 wrote:basically starlings law says that the more ventricular muscle is stretched by blood (or any muscle for that matter), the more it will contract, so better pumping. so more diastolic filling -> high end diastolic volume, more stretching of ventricular muscle, better pumping. essentially you are increasing stroke volume and Cardiac output when more blood fills ventricles.donutsandcupcakes wrote: Very similar to the previous question, but did anybody find an easier explanation of the law? Because I found some sources, but they didn't help me understand the law. Any help would be greatly appreciated.
hope this helps.
starlings forces means fluid movement due to filtration across the wall of a capillary is dependent on the balance between the hydrostatic pressure gradient and the oncotic pressure gradient across the capillary.net filtration = total factors pushing fluid out - total factors pulling fluid in.
this law is applicable in glomerular filtration and also in capillaries where fluid in and out is determined by hydrostatic pressure gradient and osmotic pressure gradient.

rules say it is supposed to be a "written test" i was counting on that!farmerjoe279 wrote:Probably with a sphygmomanometer.JoeyC wrote:Wow. With what equipment?

Re: Anatomy and Physiology B/C
If they asked for BP of a living person (with the person in the room) they should give you a sphygmomanometer and a stethoscope. You cut the blood flow of the arm with the sphygmomanometer while placing the stethoscope on the forearm. Slowly release the pressure on the arm. When you hear the blood start flowing, that's systolic pressure. Keep on relieving pressure and when you stop hearing the blood flowing, that's diastolic pressure.bp31000 wrote:rules say it is supposed to be a "written test" i was counting on that!farmerjoe279 wrote:Probably with a sphygmomanometer.JoeyC wrote:Wow.

Don't you have to time how much blood is flowing?farmerjoe279 wrote:If they asked for BP of a living person (with the person in the room) they should give you a sphygmomanometer and a stethoscope.

Re: Anatomy and Physiology B/C
Yes, you wouldn't need to time anything for BP.JoeyC wrote:No, I think you just check the pressure of the sphygomomanometer. You shouldn't need to time anything.

Re: Anatomy and Physiology B/C
Wouldn't doing a blood pressure measurement be biased? Because depending on the person their blood pressure could fluctuate at any moment based on what they're doing?farmerjoe279 wrote:Yes, you wouldn't need to time anything for BP.JoeyC wrote:No, I think you just check the pressure of the sphygomomanometer.
