Why are the ventricles called the “pumping” chambers

Medicine

Answer:

The lower chambers are called ventricles; these are the pumping chambers. There are four valves within the heart, which help control the direction of blood flow. Blood low in oxygen returns from the body and enters the right atrium. The blood travels through the tricuspid valve into the right ventricle.

A person is considered legally intoxicated in most states with a blood alcohol level of 80.0 mg/dl. calculate this concentration
Furkat [3]

The concentration expressed in parts per million is 782 ppm.

<h3>What is Parts per million?</h3>

It is calculated by dividing the mass of the solution by the mass of a solute present in one million (10⁶) parts.

<h3>Calculation for units in ppm:</h3>

Given:

Mass of  blood alcohol =  80 mg/dL = 80 x 10^{5} g/mL

Density of blood plasma or Mass of blood plasma = 1.023 g/mL

Concentration in ppm = (Mass of alcohol/Mass of plasma) x 10^{6}

= (80 x 10^{5} g/mL/ 1.023 g/mL) x 10^{6}

= 782 ppm

Hence, the concentration expressed in parts per million is 782 ppm.

kirill [66]

The attenuated oral poliovirus vaccine (OVP) is no longer administered in the U.S.A. because it can be spread to contacts and can occasionally cause poliomyelitis.

<h3>What is Vaccine?</h3>

The vaccine may be defined as any substance which is prepared for the stimulation of antibodies and furnishes immunity against one or several diseases.

Oral poliovirus vaccines have chances to revert back into their wild-type strain and again cause disease. Children vaccinated with oral polio vaccines shed poliovirus which spread to contacts.

Therefore, it is well described above.

Why do you think that Arjun must continue to take antibiotics for five weeks following his release from the hospital
3241004551 [841]

TLDR: Antibiotics must be taken several weeks to fully kill the bacteria. Else, surviving bacteria develops drug resistance.

Antibiotic prescription really depends on the patient's condition. Some conditions like major surgery or diseases that cause immunosuppression are more prone to bacterial infection, thus they must take antibiotics for prolonged periods of time to fight their current infections or prevent further infections.

Antibiotics, as a general rule, must be given 7 days or several weeks (depending on the bacteria/pathogen) to be sure that all the disease-causing bacteria are dead. If the drugs are taken only until symptoms fade, the surviving bacteria (now fewer in number and not causing symptoms) will develop mutations that may help resist the previously-taken antibiotic, giving rise to drug resistance.

Thus, Arjun must take the antibiotics for several weeks more (according to the doctor's orders, of course) to kill all remaining bacteria and also to prevent bacterial drug resistance. Which is really problematic, since we're slowly losing our number of effective antibiotics.
