1. What are the mechanics of breathing?

2. What do we inhale, exhale?3. What is the breathing center of the

body?

ReviewReviewWe breathe in air (oxygen) and breathe out carbon dioxide.Air enter the nose, passes down into the back of throat to the windpipe. In the lungs, the capillaries pick up the oxygen and goes with blood at the same time, carbon dioxide from the capillaries into the air in the lungs and is given out.

The respiratory center that control your rate of breathing are in the brainstem or medulla. The nerve cells that live within these center automatically send signals to the diaphragm and intercostal muscles to contract and relax at regular intervals

ColdCold

cold is marked by sneezing, runny nose, coughing, sore throat and headache

it is caused by a virus characterized by the swelling of the mucus membrane of the respiratory passage

BronchitisBronchitis is the inflammation of the bronchial

tubes due to infection by bacteria or virus

is a disease in which too much mucus is produced in the bronchial tubes

the more a person coughs, the more the bronchial tubes are damaged

BronchitisBronchitis

BronchitisBronchitis Acute bronchitis’ effects are coughing,

production of mucopurulet sputum and narrowing of the bronchi due to spasmodic contraction

Chronic Bronchitis is not primarily an inflammatory condition although it is frequently complicated by acute infection of which causes are cigarette smoking and air pollution

BronchitisBronchitis Chronic Bronchitis is not primarily an

inflammatory condition although it is frequently complicated by acute infection of which causes are cigarette smoking and air pollution

coughing up of excessive mucus secreted by enlarged bronchial mucus glands and cannot always be relieved by drugs

PneumoniaPneumonia is the inflammation of the lungs due to a

virus and bacteria; cough that produces yellow green phlegm, fever accompanied by chills, chest pains and abnominal pains

it is an acute chronic disease (severe or intense and persisting or recurring)

PneumoniaPneumonia

AsthmaAsthma is a condition where a person has a

difficulty in breathing and accompanied by coughing and wheezing sound when breathing out

is a respiratory disease often caused by an allergy that is marked by tightness in the chest and difficulty in breathing

AsthmaAsthma In a asthma attack, the muscle tissue in

the walls of the bronchi and bronchioles go into spasm

EmphysemaEmphysema associated with chronic bronchitis,

smoking, and advancing age

the air sacs (alveoli) of the lungs are enlarged and damaged, which reduces the surface area for the exhange of oxygen and carbon dioxide

EmphysemaEmphysema

TuberculosisTuberculosis it is caused by bacteria known as

Tubercle bacilli. The common symptoms are loss of appetite, fever, sweating at night, loss of weight, chest pain and blood sputum

it manifests itself in the lesions of lungs

AssignmentAssignmentRecall how many times you suffered from colds. What do you do?

Each group will prepare a report on the symptoms, causes, prevention and treatment of the ailment reported earlier in class.
