Transcript of The Respiratory System

Structural Plan
Objectives
Structure
Function
Respiration
Transportation of Gases
Regulation of Breathing
Breathing Patterns
Disorders
External Respiration
Exchange of gases in the lungs
Transportation of Gases

Oxygen
-little dissolved in blood
- oxyhemoglobin

Carbon Dioxide
- dissolved in blood
- Carbaminohemoglobin
- bicarbonate ions

Partial Pressures
Regulation of Respiration
Brain Stem
Cerebral Cortex
Chemoreceptors
Pulmonary Stretch Receptors
Disorders of the Upper Respiratory Tract
The Respiratory System
Quick Trivia
1. What are the functions of the Respiratory system?
Mechanics of Breathing
Inspiration
Breathing Patterns
-Spirometer- tidal volume, vital capacity, ERV, IRV, and residual volume




- Expiration

- Inspiration
Respiration
Internal Respiration
Exchange of gases in Tissue
Diffusion across membranes
Expiration
Rhinitis

Pharyngitis

Respiratory Distress in Infants and Adults

Epiglottitis

Croup

Deviated Septum

Lungs:
Pleurisy
Atelectasis
Disorders of the Lower Respiratory Tract
Acute Bronchitis
Pneumonia: Lobar, broncho, or aspiration
Tuberculosis
Restrictive pulmonary disorders: Restriction of the Alveoli
Obstructive Pulmonary disorders: Chronic Obstructive Pulmonary Disease (COPD)
Chronic Bronchitis
Emphysema
Asthma
Lung Cancer
Air Distributor
Gas Exchanger
Major:
Minor:
Filters, warms, and humidifies the air.
Makes producing speech possible
Makes it possible for the sense of smell
The Lobes of the Lungs
Right Superior Lobe
Right Middle Lobe

Right Inferior Lobe
Left Superior Lobe
Left Inferior Lobe
Alveoli
Make Your Own Lungs!
1. Inspiratory muscles contract

2. Thorax volume increases

3. Lung volume increases

4. Pressure Decreases

5. Air rushes in
Resting
1. Inspiratory muscles relax

2. Lung volume decreases

3. Pressure increases

4. Air goes out
Forceful
1. Expiratory muscles contract

2. Lung volume decreases

3. Pressure increases

4. Air goes out
In The Blood
Eupnea - Normal
Hyperventilation and hypoventilation
Dyspnea
Orthopnea
Cheyne-Stokes Respiration (CSR)
Respiratory Arrest
Effects of smoking on the Lungs
Primary cause of COPD
Major cause of Chronic Bronchitis - Emphysema results from progression of Chronic Bronchitis
75% of the cases of Lung Cancer are due to smoking
