Respiratory System

Respiratory
System
Function as a Whole
- A series of organs taking in oxygen and out carbon dioxide.
- Primary organs of the respiratory system are the lungs.
Topic
Diagram
Lungs
- 300 million alvioli
- Soft spongy
- Respiration
- Oxygen from incoming air enters the blood, and carbon dioxide, a waste gas , leaves the blood
.
Lungs
Bronchi
- Continuation of trachea
- Highways for gas exchange
- Leads inside the lungs
- Pseudo-stratified epithelium
- Goblet cells and serous cells.
- Under epithelium - well-developed spiral bands of smooth muscle.
Mouth
- Oral cavity
- Gives off carbon dioxide from trachea
- Oral mucosa
- Can substitute for nasal cavity
Nasal Cavity
- Warms, moisturizes and filters air
1. The respiratory segment
2. The olfactory segment
Sinuses
- Provide mucus
- Protect
- Lined with mucosa
Nose
- Air enters your body through your nose
- Cilia and mucus trap particles
- Takes in oxygen and provides
- Skin, epithelia,
- mucous membrane
- muscles
- nerves
- blood.
Trachea
- Epiglottis
- 20 rings of cartilage
- Larynx to Bronchi
- Ring is muscle and connective tissue.
- Mucosa lines the inside.
- Opens and lengthens slightly each breath in
- Returns to resting size each breath out.
Larynx
- Works with throat
- Cilia-ted pseudo-stratified columnar epithelium.
- Reapplied by cartilage tissue.
- Hyaline cartilage.
- Small cartilage is made up of elastic cartilage tissue.
- Respiratory Tract
- Pharynx to the Trachea
- Allows air to pass through

Cells
- Respiratory epithelium tissue lines the respiratory system like a boundary or shell and also works as moisturizer.
- Ciliated cells, Basal cells and Goblet cells.
Cells
Ciliated Cells
Ciliated
- In the trachea and bronchi.
- Shaped like a column bordered with cilia.
The airway is maintained clean because the cilia move in a rhythmic motion
Basal Cells
Basal
- Small and rectangular
- Are thought to be able to change into other cell types due to injury of the airway so they can restore the epithelial cell layer.
Goblet Cells
Goblet
- Have a shape similar to a columnar wine goblet.
- Provide mucous in order to trap scattered pieces of waste and pathogens.
- Helps keep the system healthy.
- Alveolar cells are found in the epithelium of the system’s alveoli
- These cells control gas exchange with bloodstreams so that oxygen can be given to cells throughout an organism or organ.
