The pacemakers are implants that are used for the regulation of heartbeats (correction of irregular heartbeats).

It is a small device, implanted (minor surgical procedure) just under the skin of the chest, that sends electrical impulses to the heart muscle to maintain a suitable heart rate and rhythm.

 

The pacemaker has two parts:

<span>·         </span>the leads which are threaded through the veins into the heart and implanted into the heart muscle. They send impulses from the pulse generator to the heart muscle. There can be one or more leads depending on the type of the heart problem

<span>·         </span>a pulse generator which contains the battery and a tiny computer and resides just under the skin of the chest.

<span>Each impulse causes the heart to contract. A pacemaker may also be used to treat different heart issues such as fainting spells (syncope), congestive heart failure, and hypertrophic cardiomyopathy.</span>

<span>Despite the fact that prescription drugs were used in the past to treat irregular heart rhythm, advances in medical science now allow the pacemaker to be implemented into the heart in order to more safely regulate heart rhythms for those with irregular beats.</span>

If you were an electron, and your home town was your nucleus, what would you need to do in relation to your home town to emit li
Scilla [17]

Answer:

Option B, Move closer to your home town

Explanation:

The options for the given question are as follows -

A) Knock down your previous house and build a bigger one.

B) Move closer to your home town.

C) Move further away from your home town.

D) Stay where you are but speed up your daily life

Solution -

Electrons carry negative charge while nucleus carries positive charge due to the presence of positively charged proton ions and neutral ions (which has no charge). All the electrons are attracted towards the nucleus due to its positive charge. The orbit on which an electron revolves around a nucleus has higher energy level as compared to the energy levels located in between the space of electron and nucleus.  

While moving from a high energy orbital to a low energy level orbital, an electron releases some energy.  Hence, in order to move closer to home, electron needs to push itself toward the nucleus by releasing energy

Hence, the given option is B

Why are aseptic procedures important in Microbiology laboratory health care industry?
Sever21 [200]

Answer:

Aseptic technique is important in the microbiology laboratory health care industry because it reduces the contamination risk that can have serious implications on the health of a person.

Aseptic procedures include wearing lab coats and other protective suits while working which cover all body and give protection from entry of pathogens. Sterilization of surface where work is going on, proper sterilization of all pathogenic cultures.

Therefore aseptic procedures are important to avoid contamination in the microbiology laboratory.
