1 Inhalation + 1 Exhalation = 

1 Respiration (((Ventilation)

NHALATION

• Ribs rise, diaphragm goes down→ 

• Increases the size of the thoracic cavit

• Decrease pressure thoracic → 

• Lungs expand→ 

• Air goes in

EXHALATION

• Ribs go down, diaphragm go up→

• Decreases the size of the thoracic cavity → 

• Increases the pressure in the thoracic cavity → 

• Lungs deflate→ 

• Air is forced out

pressure

Molecules move from an area of HIGH pressure TO an area of LOW pressure

• INHALE:

  • Outside pressure is higher

EXHALE:

• Inside pressure is higher

pharyc, larynx?

• Pharynx (throat)

Larynx (voice box)

• Epiglottis

• Covers the trachea when swallowing to prevent choking

• Trachea

• Also known as the windpipe

• Connects the larynx to the bronchi

• Bronchi

• Branches from the trachea and lead to each lung

• Lungs
  

• Right- 3 Lobes

• Left- 2 Lobes

• Alveoli

• Diffusion of gasses (O₂ and CO₂) occurs

• Surrounded by blood vessels 

• Capillaries

• Arteries

• Veins

• This is where the circulatory and

respiratory systems work together

asmtha

• Inflames and narrows the airways and produces more mucus. 

• Symptoms:

  • Periods of coughing

• Treatment:

  • Antibiotics

  • Use of an inhaler

Bronchitis

nflammation of the bronchi in the lungs.

Causes:

• Genetics

• Air pollution

• Respiratory infection

• Deficient antibody levels

Treatment:

• Antibiotics

• Inhalers

Emphysema

• Alveoli become damaged and eventually merge together to form large air sacs with reduced overall volume.

• Patients develop a barrel chest.

• Generally caused by:

  • cigarette smoking

  • pollution

  • industrial dust particles

COPD

• Progressive disease that makes it hard to breathe.

• causes= Long-term exposure to irritating gases or matter that is in the air (particulate matter).

• Most often from cigarette smoke.

lung cancer

• Uncontrolled cell growth in tissues of the lung.

• Growth may spread to adjacent tissues and beyond the lungs – Metastasis.  

Tuberculosis (Tb)

aused by Bacterium- Mycobacterium tuberculosis

• Transmission:

  • Droplet 

  • Airborne 

• Symptoms: (may be vague)

  • Weight loss

  • Fever

  • Night sweats

  • Loss of appetite
