Heart

Some people say the heart is like a fist

Some people say the heart is like a pump

I think the heart is like

Atwo-room, two-bathroomhouse

Although this house is not well-decorated

but it is also well-equipped

It has two rooms and two halls - right and left atria, right and left ventricles

It has four doors - aortic valve, pulmonary valve, mitral valve and tricuspid valve

◆It has walls--atria, ventricular walls (myocardium)

◆It has water pipes - the blood vessels of the heart

◆It has laying wires - the heart's electrical conduction system

Then, let's have a good

Let's get to know this "two rooms and two halls"!

Door

The door of the heart

The technical term is calledvalve

These doors are not ordinary.

Some are two doors that open to each other.

Some are made up of three doors.

They can only move in one direction.

If the door, not open much

the entry and exit space will become smaller.

This is called -valve stenosis

It may be that the hinges between the door frame and the door are not active, and the door is stuck halfway open.

It may be that the two doors open against each other, tripping, and the door opening space is small.

Normal

Narrow

If this door does not close tightly and leaks air

This is calledincomplete closing/reflux.

◆It may be that the door was bought small at the beginning and the size does not match.

It may be that the door is not of good quality or broken, and the door that was originally opened and closed in one direction has become opened and closed in both directions.

◆May be with a long time, the door is aging.

Normal

Close incomplete

If this door falls down.

This is calledflap prolapse.

It can also cause incomplete closure and reflux.

Walls

The walls of the heart

The technical term for this is theheart muscle

If this wall has a hole in it.

It's leaking wind and rain.

This is called an atrialseptal/ventricular septaldefect.

Atrial septal defect

Ventricular septal defect

If the wall is too thick

the room becomes smaller.

This is called hypertrophy.

This is called hypertrophiccardiomyopathy.

If the walls are thicker and more uniform, the room will be smaller and there will be less blood inside, so the blood pumped out will not be enough.

Or

If the walls are so thick that they block the door to the room! Blood will not be pumped out! Then you will have black dawn (black eyes), fainting, or even sudden death!

◆May be "trained" by high blood pressure.

Higher! Faster! Stronger!

Pump harder! Pump harder!

Build muscle! Build muscle!

Build muscle! Build muscle!

Get thick! Get thick!

Normal

Get thick

If the walls are too thin, the

The room is big, though

but very weak and

There is no strength to contract.

This is calleddilated cardiomyopathy.

Normal

dilated

Plumbing

The water pipes of the heart, also known asblood vessels

Used to transport blood and nourish the heart muscle

◆Atherosclerosisis a condition that occurs when the water pipes are used for a long time.

Even if you keep pouring "garbage" into it, the water pipe may be narrowed and blocked, which is called arterialplaque.

Narrowed water pipe, the water will not flow smoothly.

If the water pipe is blocked, the flow will be cut off directly!

The heart muscle is not nourished by blood.

The heart muscle is not nourished by blood, it will beischemic, evennecrosis!

Circuits

The circuitry of the heart

The technical term for this isthe electrical conduction system.

Thesinoatrial nodeis the generator

(also known as the body's own pacemaker)

Electricity that passes through theinter-nodal bundle

to the "relay station"atrioventricularnode

(if the generator goes on strike, it can generate electricity temporarily)

It then continues down through theHirschsprungbundle

to theleft/right bundle branch

Under the direction of this circuit

The heartsystoleanddiastole

If something goes wrong with the circuit

◆ the electric light may not turn on.

◆ the electric light may flash indiscriminately.

If something goes wrong with the pacing and conduction of the heart, abnormalities in the rhythm, frequency or sequence of excitation of the heart may occur, andBradycardia, sinus arrest; orTachycardia, arrhythmia, etc. May occur.

Systolic force

The house does not move

But the heart does move

The heart is like a pump

Pumping blood throughout the body

The power of the pump is called the contractionForce.

If there is a problem with the pump, the contraction force is too weak, and the blood pumped to the whole body will not be enough, and diseases such asInsufficient blood supply toEachOrganMay occur.

It is not difficult to understand the "two rooms and two halls" of the heart, right?

In fact, in the heart suite, the most important thing is the plumbing! If something goes wrong with the plumbing, our walls will rot, doors will break, and electricity will go haywire! So pay attention to protect the plumbing!
