The respitory system

Question 1

what is the conductive zone consisted of?

Answer 1

mouth/nose
Pharynx
Larynx
Trachea
Bronchioles

Question 2

what is the conductive zone?

Answer 2

The conductive zone are the structures that bring air into the lungs.
It cleans air entering the lungs
Warms the air to 37 deg before entering alveoli
Moistens air (to avoid alveoli from drying out)

Question 3

What is the respiatory zone consited of?

Answer 3

Respiratory bronchioles
Alveolar duct
Alveolar sacs

Question 4

what is the respiratory zone Involved in?

Answer 4

involved in exchange of gasses (Oxygen Into Carbon Dioxide)

Question 5

Nasal Passage

Answer 5

Mouth and nose breath in air and breath out waste
Air is moistened, and filtered in the nasal passage

Question 6

Pharynx

Answer 6

a passage from nasal cavity to larynx (and esophagus)
The pharynx is part of both respiratory and digesive system.

Question 7

Larynx

Answer 7

Passage for air only
is covered by Epiglottis when swallow. (avoids liquids from entering lungs)

Question 8

Thrachea

Answer 8

Tube that brings air from nasal passage to bronchi
has c shaped cartilage rings (support)
has goblet cell that create mucus and cillia (on epithelial tissue)

Question 9

Thrachea cillia and mucus significance

Answer 9

Cillia and mucus are significant in the Thrachea as the musuc traps microrganisms, and cillia then moves it upwads where you can then swallow it

Question 10

Primary Bronchus

Answer 10

Tubes that carry air from trechea to bronchioles, then to alveoli
This is the area where the respitory system splits into two (left lung right lung)

Question 11

respiratory zone function

Answer 11

gas exchange
oxygen from alveoli to capillaries
carbon dioxide from capillaries to alveoli

Question 12

Alveoli

Answer 12

300 mil alveoli
this is where gas exchange ocurrs
they are wrapped in capilaries
1 cell tick (to allow for easy diffusion of gasses)

Question 13

diffusion and consentration gradients

Answer 13

particles always move from a high consentration to an area of low consentration
The greater the difference in concentration the faster the diffusion
and the higher the consentration gradient

Question 14

Gas Exchange - Oxygen Diffustion

Answer 14

1. oxygen (O2) moves into alveoli
2. there is a high consentration of CO2 in capillaries
3. and a low consentration of CO2 in alveoli
4. O2 diffuses into capillaries (red blood cells) and the blood is then sent to the left side of the heart

Question 15

Gas Exchange - Carbon Dioxide Diffusion

Answer 15

1. Carbon Dioxide (CO2) moves into capillary from right side of heat
2. high consentration of CO2 in capillaries
3. Low consentration of CO2 in Alveoli
4. CO2 diffuses into Alveoli
5. CO2 moves up respiratory tract

Question 16

The diaphragm

Answer 16

its a muscle located under the lungs
Involved in breathing
When it contracts and Relaxes it changes the pressure inside the lungs

Question 17

what is happening during inhalation?

Answer 17

1. External intercostal muscles (muscles between ribs) contract and rib cage moves up and out
2. Diaphragm contracts (flattens) means volume increased in lungs
3. pressure decreases inside lungs which pushes air into lungs
4. Alveoli inflate

Question 18

what is happening during exhalation?

Answer 18

1. External Intercostal muscles relax causimg rib cage to move down and inwards
2. Diaphragm relaxes (moves back up) means the volume decresses in lungs
3. pressure increases causing air to move out of lungs
4. Alveoli deflate

Question 19

what is diffusion?

Answer 19

The process of movement of a substance (solid, liquid, or gas) from on area of higher concentration to an area of lower concentration. to spread the substance uniformly, this is called diffusion.

Question 20

Why do we have so many Alveoli in our lungs?
