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!
Slide 3
Respiratory System Organs that supply your blood with oxygen
Mouth Nose Cilia tiny hair like particles that line your nose and
trap dirt and particles Trachea Lungs Diaphragm
Slide 4
Parts of the Respiratory System Trachea- passageway in your
throat that takes air into and out of your lungs Epiglottis- 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
Slide 5
Parts of the Respiratory System Lungs- two large organs that
exchange oxygen and carbon dioxide Diaphragm- large, dome shaped
muscle below the lungs. Expands and compresses the lungs-enabling
breathing.
Slide 6
Breathing Process
Slide 7
Taking Care of your Respiratory System Avoid Tobacco use Stay
away from people who smoke Take care of your body when you have the
flu or respiratory illnesses Drink plenty of fluids Eat a healthful
diet Be physically active on a regular basis
Slide 8
Slide 9
Nervous System Body's control center Carries messages back and
forth between your brain and all parts of your body SMELL, TOUCH,
HEAR, TASTE, SEE
Slide 10
Parts of the Nervous System 1. Central nervous system Brain
Spinal Cord 2. Peripheral Nervous System Nerves that connect the
central nervous system to all parts of the body
Slide 11
Central Nervous System Brain- MOST important part Command
center, coordinator, of the nervous system Spinal Cord Long bundle
of neurons that sends messages to and from the brain and all parts
of the body
Slide 12
Activity with partner
Slide 13
Taking Care of your Nervous System Eat nutritious foods Get
enough rest Vaccinate against harmful diseases Protect yourself
from physical injury Helmet, protective eyewear Lifting properly
Follow traffic laws, wear seat -belt
Slide 14
Journal Entry What do you think happens to food once you take a
bite of something? Name the sequence of organs in the digestive
system?
Slide 15
Objective Identify Digestive, Circulatory, Muscular, and
Skeletal systems in the body and their primary function List major
components of these body systems Explain actions necessary to keep
the body systems healthy
Slide 16
Digestive System Group of organs that work together to break
down foods into substances that your cells can use
Slide 17
Where does it begin? Mouth tear and grind food with your teeth
Saliva Saliva-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
Slide 18
Digestive Organs Swallow esophogus Esophogus-contracts and
relaxes and repeatedly moves the food along to the stomach Stomach
churn and mix the food small intestine Small intestine- coiled tube
from 20-23 ft long in which about 90 % of digestion takes place
Food combines with enzymes and Villi, on the wall of the small
intestine, take in nutrients from food
Slide 19
Digestive Organs Small Intestine colon (Large Intestine) Colon-
tube 5-6 ft in length that plays a part in both digestion and
excretion Last stop for solid food
Slide 20
Caring for your Digestive System Eat balanced diet with
low-fat, high fiber food Fiber helps system work properly Drink
enough water-60-70% of your body weight is made up of water Keep
teeth healthy Get regular physical activity-systems work
better
Slide 21
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 products Heart- center of
circulatory system Blood vessels Blood Cardio (heart)-vascular
(blood vessels) system
Slide 22
Circulation Path Pg 72
Slide 23
Caring for Circulatory System Make aerobic activity a
habit-improves cardiovascular endurance Steps up the supply of
oxygen and nutrients to your body Moderate-vigorous activity-helps
cut the amount of fatty material in your blood Balanced food plan
Manage stress-stress can strain your heart and blood vessels Avoid
tobacco-nicotine narrows blood vessels-cutting down on oxygen
supply
Slide 24
Skeletal and Muscular Systems Skeletal- framework of bones and
other tissues that supports the body Protects internal organs Helps
us move 206 bones in the body
Slide 25
Definitions Joints- places where two or more bones meet 1.
Allow bones to move 2. Protect organs Tendons- type of connecting
tissue that joins muscle to bones and muscle to muscle Achilles-
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 tissue Tip of your
nose Knee joint
Slide 26
Muscular System Tissue that moves parts of the body and control
the organs Power and flexibility you need to move Skeletal Smooth
Cardiac
Slide 27
Skeletal Muscles Voluntary-you can control them Turning your
head-brain sends the message to muscles in your neck Moving your
arm
Slide 28
Smooth Muscles Bodys organs Bodys blood vessels Involuntary-
move without you consciously controlling their movement
stomach
Slide 29
Cardiac Muscle HEART involuntary
Slide 30
Caring for your Bones and Muscles Stay physically active
Flexibility exercises Stand up straight-proper posture keeps bones,
joints, and muscles in the right place Lifting heavy objects-keep
your back straight, bend your knees Eat healthy-muscles and bones
get the right nutrients and food provides fuel for energy What
nutrient can help build muscle?
