To the StudentI.Introduction to Science 3105Science 3105, From Life to Lifestyle, is the first of two courses at this level that covers LifeScience topics. You begin by learning about microscopes and how they are used. You areintroduced to the basic structures and functions of cells and the life functions common to livingthings. You will progress to an understanding of the importance of nutrition and lifestyle inhelping your body carry out life functions and maintain homeostasis.You should have your instructor check your written work when you complete the Study Guidequestions for each unit. You should also submit any lab reports and assignments that arerequired for the course. Check with your instructor to see if there is any other work that needs tobe passed in.The text for this course is science.connect1; Colbourne, Fernandez, et al; McGraw-Hill Ryerson;2002.Study GuidevScience 3105

To the StudentII.Use of Science Study GuidesBefore beginning this course, ensure you have the text and any other resources needed (see theinformation in the Introduction to this course for specifics). As you work through the StudyGuide, you will see that it is divided according to the Units listed in the Table of Contents.When you open a unit it will have the following components:Reading for this Unit:Here you will find the chapters, sections and pages of the text you will use to cover the material for this unit. Skimthe sections of the textbook, look at the titles of the sections, scan the figures and read any material in the margins.Once you have this overview of the unit, you are ready to begin. Do not be intimidated by the content. You willwork through the text, section by section, gaining knowledge and understanding of the material as you go.References and NotesWork to SubmitThis left hand column guides you through thematerial to read from the text. Read anyhighlighted notes that follow the readinginstructions. The symbols direct you tothe questions that you should complete whenfinished a reading assignment.You come across three (4) headings in this right hand column.Writing:This section comprises your notes for the unit. Here you willfind either written questions or references to specific questionsor problems from your text. You may want to write out eachquestion followed by the answer. This material should bechecked by your instructor before moving on to the next unit.Mathematical problems should have their solutions checked asyou go.Laboratory:This section indicates if there is a Core Lab that should becompleted for the unit. Let the instructor know in advance thatyou will be ready for the lab. A lab report should be submittedfor each Core Lab. Your instructor will provide guidelines as tohow s/he wants the report written.Assignment:This section indicates if there is an assignment that should becompleted for the Unit. The information in the “References andNotes” column will indicate how you obtain the assignment.These assignments frequently relate the science content totechnology, society and the environment.Computer:This section indicates that you will use a computer and a printerto complete some of the required work for the course. Ask yourinstructor for help if you are not sure how to use the computer.You will be required to print out some material each time youdo the computer work and the printouts should be included withthe written notes.Study GuideviScience 3105

Digestive ProcessesName:Date:Study the diagram and label the parts, using the list below.mouth - where food enters body; contains teeth and salivary glandsteeth - chew food into smaller pieces for swallowingsalivary glands - moisten food with enzymes that begin chemical breakdownesophagus - pushes food to stomach through wave-like muscle spasmsstomach - muscles contract to mix food; releases acids that activate chemicals to digest food;dissolves food into liquid formsmall intestine - has chemicals to digest food; neutralizes stomach acid; absorbs 80 to 90percent of nutrientslarge intestine - absorbs vitamins, minerals and watergall bladder - stores bilepancreas - provides much digestive enzymes; produces insulin to extract nutrients from foodrectum - stores solid waste (undigested food)anus - discharges solid mass of undigested food called feces

The Blood RouteName:What to Do:Trace the route that blood takes on itsjourney through the body. Colour thearteries red, to represent the oxygenatedblood they carry. Colour the veins blue, torepresent the deoxygenated blood theycarry.Although the lungs are considered part ofthe respiratory system, they play a crucialrole in the circulatory system. Withoutlungs, the blood circulating through yourbody would have no way of replenishing itsoxygen supply or getting rid of waste gases processes that are vital for survival. Thecirculatory system relied on the lungs to“refresh” the blood. Without this constantrefreshment, the blood in this closedtransport system would soon be toxic,delivering more harm than good to thebody’s cells.How exactly do your lungs work? They aremade up of millions of small air chambersDate:Pay special attention to the heart and lungs remember that these organs contain bothoxygenated and deoxygenated blood. Howcould you best represent this on thediagram?called alveoli. Alveoli have a large surfacearea to allow for maximum gas exchange. Avast network of tiny blood vessels surroundsthe alveoli, and it is across the membranesof these blood vessels that oxygen andcarbon dioxide are exchanged.Then, as you know, the oxygen is carried bythe blood to the cells of your tissues, whilethe carbon dioxide is carried by the bloodaway from the cells, back to your lungs.When you exhale, the carbon dioxide travelsfrom the lungs out through your nose andmouth and is released into the environment.
