Eww!
2
The water's dirty!
3
Oh dear!
4
Looks like our filters tired, Kitty!
5
Filtering isn't easy, you know!
6
Even our kidneys can get worn out!
7
Really?
8
What happens then?
9
The humans need a little artificial help.
10
Let me show you by answering how dialysis works.
11
Zoom in!
12
Every day, your two bean -shaped organs called kidneys quietly pull off one of the most amazing jobs in your body.
13
They clean your blood.
14
They remove waste like urea, valence, electrolytes such as sodium and potassium and regulate fluid levels,
15
blood pressure and even red blood cell production.
16
The purified blood then returns to circulation while the waste is excreted from the body as urine.
17
But sometimes, due to conditions such as diabetes, long -term high blood pressure,
18
severe infections or certain genetic disorders,
19
the kidneys may lose their ability to function properly this loss of function is known as kidney failure
20
or renal failure when this happens toxins fluids
21
and salts begin to build up in the body leading to fatigue nausea swelling
22
and further increases in blood pressure if left untreated these imbalances can damage the heart,
23
lungs and other vital organs.
24
That's where dialysis comes in.
25
An artificial way to take over the kidneys cleansing job of removing waste and extra fluid from the blood.
26
But then how does it work?
27
Well there are two main types of dialysis.
28
Hemodialysis and peritoneal dialysis.
29
Each using a different method but based on the same scientific principles of diffusion and osmosis
30
The movement of particles and water across a semi -permeable membrane
31
In hemodialysis, blood is cleansed outside the body using a machine called a dialyzer
32
Often referred to as an artificial kidney
33
To prepare for treatment, a small surgical procedure creates a vascular access such as an arteriovenous AV fistula,
34
a direct connection between an artery and a vein or a graft, which is a soft plastic tube connecting the two.
35
During each dialysis session, two needles are inserted into this access point.
36
Blood flows out of the body through one needle and travels through tiny hollow fibres inside the dialyser.
37
As it moves along, waste molecules like urea
38
and excess potassium pass through the fibre walls into a special cleansing fluid called dialysate,
39
while essential components remain in the bloodstream.
40
The cleaned blood then returns to the body through the second needle and into the veins.
41
This process usually takes about four hours and is performed three times a week.
42
Peritoneal dialysis, on the other hand, turns the body into its own filter.
43
A soft tube called a catheter is surgically placed into the patient's abdomen.
44
The peritoneum, the thin membrane lining the abdominal cavity,
45
acts as the natural semi -permeable filter.
46
Dylacate fluid is infused into the cavity where it absorbs wastes and excess water from the surrounding blood vessels.
47
After several hours, the used fluid now containing toxins is drained into a collection bag
48
this process called an exchange can be done manually several times a day
49
or automatically overnight with the machine
50
while dialysis can't cure kidney disease it provides a remarkable bridge keeping people alive
51
and healthy enough to await a transplant or continue living and act manageable life.
52
Trivia time!
53
Did you know each kidney is roughly the size of a closed fist and weighs just under 0 .4 kilograms?
54
Also, each kidney contains approximately 1 million microscopic filtering units called nephrons.
55
Sketching time!
56
Today's sketch of the day goes to scarlet harris hope
57
you learned something critical today until next time
58
it's me dr binocs zooming out kitty why
59
or not did you bring a dialysis machine to replace the ordinary water filter
60
Oh, Kitty, never mind.

什麼是跟讀法？

跟讀法 (Shadowing) 是一種有科學依據的語言學習技巧，最初開發用於專業口譯員的培訓，並由多語言者Alexander Arguelles博士普及。這個方法簡單而強大：您在聽英語母語原聲的同時立即大聲重複——就像是一個延遲1-2秒緊跟說話者的影子。與被動聽力或語法練習不同，跟讀法強迫您的大腦和口腔肌肉同時處理並模模擬實的講話模式。研究表明它能顯著提高發音準確性，語調，節奏，連讀，聽力理解和口語流利度——使其成為雅思口語備考和真實英語交流最有效的方法之一。
