Day 1

Bell Ringer!Welcome to Quarter Three Health with

Mrs. Puckli!!!

Take the Bell Ringer at the side table RESPIRATORY DIAGRAM and get started immediately upon entering!

Respiratory SystemOrgans that supply your blood with oxygen

MouthNose

Cilia –tiny hair like particles that line your nose and trap dirt and particles

TracheaLungsDiaphragm

Parts of the Respiratory SystemTrachea- passageway in your throat that

takes air into and out of your lungsEpiglottis- flap of tissue in the back of your

mouth that keeps food out of your trachea(activity)Bronchi-two passageways that branch from

the trachea, one to each lung

Parts of the Respiratory SystemLungs- two large organs that exchange

oxygen and carbon dioxideDiaphragm- large, dome shaped muscle

below the lungs. Expands and compresses the lungs-enabling breathing.

Breathing Process

Taking Care of your Respiratory SystemAvoid Tobacco useStay away from people who smokeTake care of your body when you have the flu

or respiratory illnessesDrink plenty of fluidsEat a healthful dietBe physically active on a regular basis

Nervous SystemBody's control center

Carries messages back and forth between your brain and all parts of your body SMELL, TOUCH, HEAR, TASTE, SEE

Parts of the Nervous System1. Central nervous system

Brain Spinal Cord

2. Peripheral Nervous SystemNerves that connect the central nervous

system to all parts of the body

Central Nervous SystemBrain- MOST important part

Command center, coordinator, of the nervous system

Spinal CordLong bundle of neurons that sends messages to

and from the brain and all parts of the body

Activity with partner

Taking Care of your Nervous SystemEat nutritious foods Get enough restVaccinate against harmful diseasesProtect yourself from physical injury

Helmet, protective eyewearLifting properlyFollow traffic laws, wear seat -belt

Journal EntryWhat do you think happens to food once you

take a bite of something? Name the sequence of organs in the digestive system?

ObjectiveIdentify Digestive, Circulatory, Muscular, and

Skeletal systems in the body and their primary function

List major components of these body systemsExplain actions necessary to keep the body

systems healthy

Digestive SystemGroup of organs that work together to break

down foods into substances that your cells can use

Where does it begin?Mouthtear and grind food with your

teethSalivaSaliva-digestive juice produced by salivary

glands in your mouth-moistens and softens food making it easier to swallow

Amylase- enzyme in saliva that breaks down carbohydrates in food changing it from starch to sugar Enzyme-substance that aids in body's chemical

reactions

Digestive OrgansSwallowesophogus

Esophogus-contracts and relaxes and repeatedly moves the food along to the stomach

Stomachchurn and mix the foodsmall intestineSmall intestine- coiled tube from 20-23 ft long

in which about 90 % of digestion takes placeFood combines with enzymes and Villi, on the

wall of the small intestine, take in nutrients from food

Digestive OrgansSmall Intestinecolon (Large Intestine)

Colon- tube 5-6 ft in length that plays a part in both digestion and excretion

Last stop for solid food

Caring for your Digestive SystemEat balanced diet with low-fat, high fiber food

Fiber helps system work properlyDrink enough water-60-70% of your body

weight is made up of waterKeep teeth healthyGet regular physical activity-systems work

better

Circulatory System(cardiovascular system)A group of organs and tissues that act as a

transfer station carrying needed material to cells and removing their waste productsHeart- center of circulatory systemBlood vesselsBlood

Cardio (heart)-vascular (blood vessels) system

Circulation PathPg 72

Caring for Circulatory SystemMake aerobic activity a habit-improves

cardiovascular enduranceSteps up the supply of oxygen and nutrients to

your bodyModerate-vigorous activity-helps cut the amount

of fatty material in your bloodBalanced food planManage stress-stress can strain your heart and

blood vesselsAvoid tobacco-nicotine narrows blood vessels-

cutting down on oxygen supply

Skeletal and Muscular SystemsSkeletal- framework of bones and other

tissues that supports the bodyProtects internal organs Helps us move206 bones in the body

DefinitionsJoints- places where two or more bones meet

1. Allow bones to move2. Protect organs

Tendons- type of connecting tissue that joins muscle to bones and muscle to muscleAchilles- attaches your calf to your heel bone

Ligaments- type of connecting tissue that holds bones to other bones at the joint (knees and ankles)

Cartilage- strong, flexible tissue that allows joints to move easily, cushions bones, and supports soft tissueTip of your noseKnee joint

Muscular SystemTissue that moves parts of the body and

control the organsPower and flexibility you need to move

Skeletal Smooth Cardiac

Skeletal MusclesVoluntary-you can control them

Turning your head-brain sends the message to muscles in your neck

Moving your arm

Smooth MusclesBody’s organs Body’s blood vesselsInvoluntary- move without you consciously

controlling their movementstomach

Cardiac MuscleHEARTinvoluntary

Caring for your Bones and MusclesStay physically active

Flexibility exercisesStand up straight-proper posture keeps

bones, joints, and muscles in the right placeLifting heavy objects-keep your back straight,

bend your kneesEat healthy-muscles and bones get the right

nutrients and food provides fuel for energyWhat nutrient can help build muscle?
