Help /sci/ I need some assistance with my physiology assignment I was sick when we covered most of the stuff on the heart and im stumped on how to answer this question.

Left sided heart failure, is a condition which affects patients following a heart attack. In these cases, the heart attack causes some of the myocardium in the left ventricle to die, and, as a result the left ventricle does not work as well as it did when it was healthy. Given your knowledge of the cardiac cycle and the role of the left ventricle. Explain what would happen to Cardiac Output and Blood Pressure as a result of left heart failure. Use the two equations below to help illustrate your answer;
CO = HR x SV and BP = CO x TPR

CO will decrease as SV decreases due to the weakened myocardium. Less muscle means a lower volume of blood pumped per stroke.

The left ventricle is extremely important as it's the last chamber before blood leaves the heart and enters the systemic circuit. A single stroke from the LV must push a bolus or "wave" of blood through the arteries, capillary beds, veins all the way back to the right atrium. There's an interestingly related condition called Left Ventricular Hypertrophy in which the LV becomes "overgrown" or puts on much more muscle mass to compensate for hardened arteries and higher blood pressure (which would resist the bolus from entering the systemic circuit). So the myocardium grows to provide a better SV, in that case. Left Side Heart Failure would basically b e the inverse.

why don't you medshits just learn pattern recognition techniques and let the memorization for computers?

Wt du think about this article and the lgbt response to it...

Apparently you can train algorithms to recognise gay people based on facial features.

Humans can often tell when someones gay

Why not computers?

I think body language is much more telling though

When a medication should be taken "with food" because food increases it's absorbtion, how long do you have after eating to reap this benefit?
Would a drink with absorbable nutrients work the same in lieu of food?

Drug in question specifically is Spironolactone.

there's lots of reasons.

One is first pass metabolism, that can decrease drug absorption by increasing drug metabolism.

Another would be the opposite, the drug could be more potent because there is nothing to dilute it, and depending on the drug this can mean the drug doesn't last as long, or is much more potent

But mostly i think you are supposed to drink water and have eaten when you take meds because this is how the drugs are made to be taken.


just ask your doctor.

Can humans quantum tunnel theoretical although impossiblely low does it explain why some people dispear from the face of the earth all of a sudden

nah that's just cause they blocked u on facebook

can u rlly blame them?

>>9162636
It's technically possible but the odds are so low that there's an equal chance Jesus Christ would quantum tunnel to Manhattan in the year 2018
>>
>>9162636
Every single particle that you are made up of would have to simultaneously quantum tunnel in the same direction.

How is the boiling point of carbon dioxide lower than its melting point? How does sublimation occur? I don't understand.
4 posts and 2 images submitted.
>>
>>9162460
The boiling point isn't lower than the melting point, neither of those exist at STP because liquid co2 doesn't exist at STP. However at higher pressures and temps it does
>>
Is it not true though that, if one were to decrease the temperature or increase the pressure of gaseous carbon dioxide, it would reach of solid state before a liquid state?
>>
>>9162746
Depending on your starting temperature and pressure, it could be a yes or a no. You just described the reverse of sublimation, which is entirely possible. Look up how to read a phase diagram then look at the one I posted earlier. For your purposes you can ignore the supercritical fluid phase

Is the manner in which electrons behave not also determined? We are incapable of predicting their motion but nonetheless they must follow some order.
>>
>>9162436
Why must they follow some order? Isn't it equally likely that there is randomness in the universe? Even assuming they follow some order, does it even matter since noone will ever know and predicting the future far enough ahead is still impossible
>>
>>9162815
You mean, by "random" to say that certain things may occur without a previous cause? I suppose there is a small chance.

Why are we eating so much bread then? Carbs are bad for teeth, they turn into sugar quick. So why does the governments focus on chocolate and shiiet instrad of bread and cereal?
