1AIM: How do the different systems of the body function to keep you alive? 4/15/13DO NOW:Pick up your quiz & finish it.HOMEWORK:ILS LE REVIEW BOOKRead p. 1-6Answer Questions # on pSCAN-TRONS DUE – 8AM Tomorrow
2How are multicellular organisms organized? CellsTissueOrganSystemsOrganism
3What is the function of the digestive system Prepares food (nutrients) for absorption into the bloodHow are the two types of digestion different?Mechanical digestion (chewing)Chemical digestion (enzymes)
4What is the function of the Respiratory System? Takes in oxygen to make energyRemoves carbon dioxideWhere does oxygen & carbon dioxide exchange tale place?Alveoli is the site of gas exchange in the lungsAlveoli
5What is the function of the Circulatory System? Transports materials throughout the body.What are the components of blood?Red Blood cells – carry oxygen & CO2White Blood cells – Fight infectionsPlatelets – Clot blood (stop bleeding)Which organ pumps the blood?Heart – pumps the blood
6Name the 3 types of blood vessels? Arteries, Veins, CapillariesWhich blood vessels carry blood away from the heart? Toward the heart?Arteries – carries blood Away from heartVeins – carries blood to the heartIn which blood vessels does gas and nutrient exchange take place?Capillaries – smallest – gas & nutrient exchange takes place with the cell
7What is the function of the Immune System? To help protect the body against microorganismsWhat are the parts of the immune system?Skin, mucous, acid, white blood cells, antibodiesWhat is a vaccine and why are they important?Vaccinations- weak virus, helps your body produce antibodiesHow does an infectious disease differ from a non-infectious disease?Infectious DiseaseContagious, can catchCaused by a microorganismNon infectious DiseaseCannot catch
8What is the function of the Excretory System? To remove waste from the bodyIdentify the organs of the Excretory System?Kidneys- urineLungs-carbon dioxideSkin- perspire water & saltsLiver- removes chemicals & toxins
9What is the function of the Nervous System? Controls your bodyHelps your body respond to a stimulusIdentify the organs of the Nervous System.BrainSpinal cordNeuronsDescribe the speed of the electrical nerve impulses?Electrical impulses travel at lightning quick speeds through your neurons.
10What is the function of the Endocrine System? Controls responses to internal and external stimuli.How does the endocrine system control responsesHormonesIdentify the organs of the endocrine.
11What is the function of the Muscular & Skeletal Systems? StructureSupportLocomotion (movement)Identify the structures that make up the Muscular & Skeletal System.MusclesBones
12What is the function of the reproductive systems? Produces sex cells necessary for the production of offspring.Identify the male and female organs of the reproductive system?Male- TestesFemale- OvariesWhat are the male and female sex cells?Male – SpermFemale – Eggs
13Summary Questions:How does mechanical digestion differ from chemical digestion?How do Arteries differ from veinsExplain how the respiratory and circulatory systems work together to keep us alive.How does our immune system protect us?How does our excretory system remove wastes?How do 8 of the systems of our body function to help us run away from a dog chasing us?
