This week 4/20/20- 4/24/20

Monday- Watch lecture on Respiratory System. Guided Notes found in Week 3

Packet.

Tuesday- Watch video lesson on C.P.R. and History of Heimlich Maneuver. There will be questions on the quiz about these topics. (**I have included a CPR Info PPT --- You do not have to print this.) Complete the “Respiratory System Packet”

Worksheet/Labeling found in the packet.

Wednesday- Complete “What is Breathing” reading passage and questions.

Thursday- Complete the Respiratory System Review sheet.

Friday- Complete Quiz over Week 3 information. Link on my teacher’s website. Due

Monday April 27th by 6 PM.

**There are printed packets located for pickup at the school Monday-Friday from 8am till noon. The Quiz for Week 3 is linked on my website.

Respiratory System Guided Notes

Overv iew -­‐ Major Function: ____________________________________________________

_______________________________________________________________ o Can’t do this without the help of the: _____________________________

-­‐ Key Structures: Nose, Pharynx, Larynx, Trachea, Lungs, Diaphragm

Funct iona l Zones -­‐ ____________________________- warms, humidifies, and filters air as it travels to

the respiratory zone o Air enters the nose through ______________ and is warmed as it passes through

the nasal cavity o Air moves through the _____________, which connects the nasal cavity and mouth

to the larynx (____________) and esophagus § Air travels down the larynx to the trachea (____________)—Begin Lower

Respiratory Tract § The ____________ is a piece of cartilage that blocks the larynx when we

swallow food -­‐ Lower Respiratory- Air travels down the trachea which splits into right and left primary bronchi

that enter the lungs § Right lung has ____ lobes § Left lung has _____ lobes § Lungs are surrounded by pleurae= serous membranes that line the thoracic

wall and diaphragm o The primary bronchi subdivide into secondary bronchi o The secondary bronchi further segment into tertiary bronchi

§ The smallest passageways (less than 1mm)= ___________________ -­‐ _________________________- where gas exchange occurs in the bronchioles,

alveolar ducts and alveoli o Bronchioles empty into the alveolar ducts, which dead end in tiny alveolar sacs that

contain alveoli (thin- walled air sacs)

Gas Exchange -­‐ Gas Exchange= ___________________________________________________

______________________________________________________________ o Arteries and veins feed into each alveolar sac, with capillaries connecting to each

alveoli o CO2 moves ________ of the blood and ________ the alveoli o O2 moves ________ the blood and ________ of the alveoli

Breath ing -­‐ Diaphragm= __________________________________________________

o Separates the thoracic cavity from the abdominal cavity

-­‐ Volume changes in lungs à pressure changes, which causes air to move o When we ___________ the diaphragm _____________ à room for lungs to

expand o When we ____________ the diaphragm’s contraction is released and the lungs

return to their deflated size -­‐ 2 Phases

o 1. __________________= when air moves into the lungs § Inspiratory muscles contract and the diaphragm __________ à increased

volume in thoracic cavity § Lungs expand à _____________________

o 2. __________________= when air exits out of the lungs § Inspiratory muscles relax and the diaphragm __________ à decreased

volume in thoracic cavity § Lungs recoil à _______________________

Breath ing o The intercostal muscles contract à pulling the ribs up, and the diaphragm contracts

and moves down à pulling air into the body through the mouth or nostrils o Air passes through the ______________ or oral pharynx to the trachea o The trachea filters air using tiny hair-like __________ and ___________ o Air moves down the trachea and into the _________ and ________ bronchi

§ Trachea is very stiff so it stays open and doesn’t collapse every time pressure drops when you exhale

o Air arrives at the alveoli where ___________________ will occur o ___________ that has been pulled into the alveoli diffuse through the really thin-

alveoli membrane and into the pulmonary capillaries to be circulated through the heart and to the rest of the body for cellular respiration

Breath ing

o ___________that has been created by the body through cellular respiration is brought by the capillaries to the alveoli and diffuse into them

o The diaphragm relaxes, moving up and causing air (containing CO2) in the alveoli to be exhaled

Ce l lu lar Resp i ra t ion= _________________________________________________ ___________________________________________________________________

C6H12O6 + 6O2 à 6CO2 + 6 H2O + energy (ATP) -­‐ This metabolic process is possible because of diffusion and bulk flow, accomplished by the

respiratory and CV systems o ______________= movement of gases, occurring at short distances o __________________= movement of large amounts of gases to different

structures that they then diffuse into
