1
How do the respiratory, circulatory and digestive systems work together?
2
How do your digestive, circulatory, and respiratory systems work together?
3
Respiratory System What does it do?
It moves oxygen from the outside environment into the body Removes carbon dioxide and water
4
Why does the body need oxygen?
Without oxygen, cells cannot “burn” nutrients to release energy
5
Bronchioles within the lungs
Respiratory Tract The Path of Air Nose and Mouth Pharynx Larynx Trachea Bronchi Lungs Bronchioles within the lungs Alveoli
6
Pathway of Air 1- Nose 2- Mouth 3- Larynx 4- Lungs 5- Bronchi
6- Diaphragm 7- Pharynx 8- Trachea 9- Bronchi 10- Bronchioles 11- Alveoli
7
Path of Air: 1) Nose and 1) Mouth
The organ where air enters the body. Secondary entry for air into the body
8
Path of Air: 2) Pharynx (Throat)
After air enters the nose/mouth it moves downward to the pharynx
9
Path of Air: 3) Larynx Passage way for air
Epiglottis is present to close of digestive path Voice box
10
Your Voice Larynx- Voice box located in the top part of the trachea, underneath the epiglottis Vocal Cords- Folds of connective tissue that stretch across the opening of the larynx, which produce your voice
11
... and infection of the trachea. 289 x k - jpg Path of Air: 4) Trachea It is the windpipe leading from the pharynx to the lungs. The walls of the trachea are made with rings of cartilage, which protect it from collapsing.
12
Path of Air: 5) Bronchi The passages that direct air into the lungs.
13
Path of Air: 6) Lungs and Bronchioles
The lungs are the main organ of the respiratory system, where air moves through smaller and smaller bronchi (bronchioles) until it reaches the alveoli.
14
Path of Air: 7) Alveoli Alveoli are tiny sacs of lung tissue specialized for the movement between air and blood. (Look like grapes)
15
Think About It! What effects a person’s breathing?
What is the difference between breathing and respiration?
16
Respiration What is it? The process in which oxygen and glucose undergo a complex series of chemical reactions inside cells.
17
Breathing What is it? Breathing is movement of air into and out of lungs, while respiration is chemical reactions inside the cells
18
Lesson 3: Goal By the end of the period, you will to the understand how gas exchange occurs in the lungs and also the functions of various organs the are related to the respiratory system.
19
How does gas exchange occur? Where does it occur?
It occurs in the lungs at the alveoli. How? Oxygen passes through the alveoli into the blood and carbon dioxide passes out of the blood and into the alveoli.

- The Respiratory System
22
Diaphragm A large dome-shaped muscle that plays an important part in breathing.
23
Respiratory Diseases Bronchitis- An irritation of the breathing passages in which they become narrower than normal and may be clogged with mucus
24
Respiratory Diseases Emphysema- A serious disease that destroys lung tissue and causes difficulty breathing
25
Respiratory Diseases Lung Cancer- When cancerous growths, or tumors, take away space in the lungs that should be used for gas exchange
26
Respiratory Diseases Asthma- Constriction of the smooth muscles around the respiratory passageways frequently caused by an allergic reaction
27
Problems Affecting the Respiratory System
