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?
