Presentation Transcript

Slide1

Respiratory System

Your system for breathingSlide2

NoseSlide3

Nose

Function:

Inhales Oxygen (O

2

) and Exhales Carbon Dioxide (CO

2

)

Uses nose hair (Cilia) to filter dust and germs from entering the lungs

Moistens the air

Warms air

Evidence:

Sneezing

Boogers

Nose Hair (cilia) Slide4

MouthSlide5

Mouth

Function:

Allows more air to come into the body

Evidence:

Exercise and out of breath = breathe through your mouth

Sick and nose is clogged = breathe through your mouth Slide6

TracheaSlide7

Trachea

Function:

Brings

Oxygen

from nose/mouth to the lungs and removes Carbon Dioxide

Lined

with cartilage to keep it open and protect it.

Evidence:

X-Ray

TracheotomySlide8

LarynxSlide9

Larynx

Function:

Air vibrates the vocal cords to make noise (talking

)

Voice box

Evidence:

Put two fingers on voice box and hear and feel it vibrateSlide10

DiaphragmSlide11

Diaphragm

Function:

A muscle that moves up to force air out of the lungs when you exhale

Contracts a

nd

moves down to let extra space in when you inhale

Evidence:

Lung model

Big deep breathe

Video from station 1Slide12

EpiglottisSlide13

Epiglottis

Function:

Small flap that covers the trachea when you swallow so food does not get into your lungs

Evidence:

X-ray video

Coughing when something goes down the wrong pipeSlide14

PharynxSlide15

Pharynx

Function:

It is your throat

Lets air go down to

your trachea

You also swallow food

and water with

Evidence:

Picture

Sore throatSlide16

BronchiSlide17

Bronchi

Function:

Tubes to take

O

2

to alveoli and remove CO

2

from alveoli to exhale

Evidence:

Bronchitis

Animation video station 1Slide18

AlveoliSlide19

AlveoliSlide20

Alveoli

Function:

Small sacs that send oxygen (O

2

)

to the cells and removes carbon dioxide (CO

2)

from cells.

Where gas exchange takes place.

Evidence:

Animation

Class demonstrationSlide21

LungSlide22

Lung

Function:

Contains the bronchi and alveoli

Protects these structures.

Evidence:

Microscope/Stereoscope slides
