00:00.940 --> 00:02.860
Emphysema is a type of chronic

00:02.870 --> 00:06.120
obstructive pulmonary disease or COPD

00:06.130 --> 00:08.360
that involves damage to the alveoli in

00:08.360 --> 00:10.830
the lungs . Doctor Patel , What can you

00:10.830 --> 00:13.230
tell us about emphysema ? While dr

00:13.230 --> 00:15.063
greene and emphysema , the walls

00:15.063 --> 00:17.008
between many of the Alvin Ally are

00:17.008 --> 00:19.230
damaged . As a result , the Alvin ailey

00:19.230 --> 00:21.286
lose their shape and become floppy .

00:21.286 --> 00:23.220
This can cause air to get trapped

00:23.220 --> 00:25.650
inside the lungs , which leaves no room

00:25.650 --> 00:28.420
for new air to get in trapped air can

00:28.420 --> 00:30.640
also force the diaphragm the muscle at

00:30.640 --> 00:32.529
the bottom of the lungs to become

00:32.529 --> 00:34.850
displaced , which makes it less able to

00:34.850 --> 00:37.370
assist in breathing . For this reason ,

00:37.380 --> 00:39.810
people with emphysema often feel like

00:39.810 --> 00:42.490
they can't take a deep breath damage

00:42.490 --> 00:44.712
can also destroy the walls of the Alvin

00:44.712 --> 00:47.210
ally , leading to fewer and larger

00:47.210 --> 00:49.690
Alvin Ally instead of many tiny ones .

00:49.700 --> 00:51.910
When this happens , the amount of

00:51.920 --> 00:54.410
oxygen and carbon dioxide exchange

00:54.410 --> 00:56.132
between the Alvin ally and the

00:56.132 --> 00:58.420
capillaries is reduced . As a result ,

00:58.420 --> 01:01.160
the body doesn't get as much oxygen as

01:01.160 --> 01:01.860
it needs .
