🚭 Chronic Obstructive Pulmonary Disease (COPD)

This paragraph delves into Chronic Obstructive Pulmonary Disease (COPD), a common lung disorder that restricts airflow and is often associated with emphysema or chronic bronchitis. The condition arises from overexposure to irritants such as chemical fumes, air pollution, dust, and cigarette smoke, leading to persistent lung inflammation. This inflammation results in increased mucus production and airway thickening, which in turn restricts air flow. Symptoms of COPD include wheezing, chest tightness, excessive mucus production, frequent respiratory infections, and shortness of breath during simple activities. Although incurable, COPD can be managed with oxygen therapy, medication, and pulmonary rehabilitation. Lifestyle changes, such as avoiding smoking and air pollution, can also help alleviate symptoms.

also another organ called diaphragm

which contains intercostal muscles that

contract and relax and that is important

during breathing respiratory system

function as to provide the surface area

for gas exchange of air into circulating

blood it also move air to and from the

lungs at the same time it participates

in Al Factory s which is the sense of

smell that detects and discriminate

others as well as social cues which

influence our inate responses now we

will continue onto the physiology part

of the respiratory system the nasal

cavity and fing play crucial roles in

warming motioning and filtering air

before it enters the respiratory tract

this helps protects the delicate lungs

tissue from harmful particles and

pathogens next trachea and bronchite

provide a pathway for air to move into

and out of the lungs their cartilagenous

structure help maintain an open airware

while smooth muscle in their wall allows

for a regulation of air flow for lungs

gas exchange occurs in the alali where

oxygen from inhal air diffuses into the

bloodstream and carc from the blood

diffuses into the AL to be exhaled the L

surface area of the alili and the

thinness of their walls facilate

efficient gas exchange during inhalation

the diaphragm contracts and move

downwards increasing the volume of toric

cavity simultaneously the intercostal

muscle contract and dispending rib cage

this create negative pressure in the

lungs causing air to be drawn in

exhalation occurs when these muscles

relax allowing the Lums to recall and

expel

air now that we know all about the

normal functioning of the lung we can

talk about the disorder of the lung

chronic obstructive pulmonary disease

also known as

COPD COPD is a common lung problem also

known as empyema or chronic

bronchitis that causes restricted air

flow hence breathing problems it is

caused by overexposure to certain

irritants for example chemical fumes air

pollution dust and cigarette smoke in

response to this irrit ation the lungs

undergo persistent

inflammation persistent inflammation

then causes increase in mucus production

and thickening of the Airways hence

restricting and limiting air

flow some of the signs and symptoms of

chronic obstructive pulmonary disorder

include

breezing tightness of the chest over

production of flame frequent respiratory

infections and diseases and shortness of

breath even after undertaking simple

activities unfortunately COPD is

incurable but it can be managed and
