1
The skeleton is made up of bones, which provide support and shape to the body.
2
They protect soft internal organs, such as the brain and heart, from injury.
3
Together with muscles, strong bones enable the body to move freely.
4
Bones have a solid outer surface called compact bone.
5
The inner bone is called spongy bone
6
because it is less dense than compact bone and has many small holes like a sponge.
7
Bones contain cells called osteoclasts that break down bone tissue.
8
Other cells, called osteoblasts, make new bone tissue using minerals such as calcium and phosphate from the blood.
9
Hormones such as estrogen, growth hormone,
10
and testosterone help keep the number and activity of osteoblasts higher than osteoclasts so that more bone is made than removed.
11
Physical forces and pressure during exercise also help bones to grow stronger and denser.
12
These processes allow bones to grow strong in children and young adults.
13
People have their strongest, most dense bones, called peak bone mass, in their 30s.
14
After this age, osteoclasts gradually remove more bone than the osteoblasts make.
15
Osteoporosis is a condition that leads to weakened bones, causing them to break more easily.
16
Healthy bone is dense enough to support and protect the body, and to handle the stresses of movement and minor injuries.
17
However, people with osteoporosis have abnormally thin bones with larger holes in the spongy bone.
18
There are two types of osteoporosis.
19
Primary osteoporosis is usually related to older age, as well as a reduced amount of estrogen in women.
20
Secondary osteoporosis affects both children and adults.
21
It is related to other diseases or conditions, such as cancer, hormone problems, or use of certain medications.
22
A person has a greater risk for either type of osteoporosis
23
if they don't develop enough bone mass when they're growing from childhood to adulthood.
24
Risk factors that can lead to low peak bone mass include a family history of osteoporosis,
25
being white or Asian, being female,
26
a poor diet, certain medications such as steroids or certain seizure medicines,
27
lack of physical activity and weight -bearing exercise, • And lifestyle behaviors, such as smoking and drinking too much alcohol.
28
A person also has a greater risk for either type of osteoporosis
29
if they have an abnormal amount of bone loss after age 30.
30
Some bone loss is normal after this age.
31
However, a person with the same risk factors for low peak bone mass can be more likely to get osteoporosis as they age.
32
Increased bone loss is also common in women after the time of a woman's last period, called menopause.
33
After menopause, a woman's ovaries stop making the hormone estrogen.
34
With the drop in hormones, bone -removing cells, called osteoclasts, are more active than the bone -making cells, called osteoblasts.
35
Bones may break or fracture easily because they're unable to withstand the physical strain and pressure from even normal activities.
36
Common fracture locations in people with osteoporosis include the wrists, spine, and hips.
37
Building strong,
38
healthy bones through a diet rich in calcium and vitamins and getting regular exercise can help prevent as well as treat osteoporosis.
39
Common medications for osteoporosis include biphosphonates,
40
a medication called denosumab, Selective Estrogen Receptor Modulators, or CIRMs and calcitonin.
41
In general, these medications act on bone -removing cells, called osteoclasts.
42
Parathyroid hormone acts on bone -making cells, called osteoblasts.
43
Food or supplements containing calcium and vitamin D are also recommended for osteoporosis.

이 영상으로 연습하는 방법
- 먼저 말하지 않고 영상을 끝까지 듣고 모르는 단어를 적어 둡니다.
- 보통 속도로 한 문장씩 섀도잉하고, 화자의 리듬과 맞을 때까지 반복합니다.
- 자신의 목소리를 녹음해 원본과 비교하고, bone, hormone, dense 같은 단어에 특히 주의합니다.
쉐도잉이란? 영어 실력을 빠르게 키우는 과학적 방법
쉐도잉(Shadowing)은 원래 전문 통역사 훈련을 위해 개발된 언어 학습 기법으로, 다언어 학자인 Dr. Alexander Arguelles에 의해 대중화된 방법입니다. 핵심 원리는 간단하지만 매우 강력합니다: 원어민의 영어를 들으면서 1~2초의 짧은 지연으로 즉시 소리 내어 따라 말하는 것——마치 '그림자(shadow)'처럼 화자를 따라가는 것입니다. 문법 공부나 수동적인 청취와 달리, 쉐도잉은 뇌와 입 근육이 동시에 실시간으로 영어를 처리하고 재현하도록 훈련합니다. 연구에 따르면 이 방법은 발음 정확도, 억양, 리듬, 연음, 청취력, 말하기 유창성을 크게 향상시킵니다. IELTS 스피킹 준비와 자연스러운 영어 소통을 원하는 분들에게 특히 효과적입니다.
