Cardiovascular & Circulatory Systems Cardiovascular & Circulatory System Function: The Body’s Transport System 1. Heart 2. Blood Vessels 3. Blood Structures - Heart 1. Shape - Strawberry 2. Size - Fist 3. Weight - 1 pound 4. Location – Center of chest THE HEART Heart - Structures 1. Septum – Divides the Heart into Right and Left 2. Chambers - Note: It Is A Hollow Organ Atrium – Top (smaller) Ventricle – Bottom (bigger) 3. Valves – Keep blood flowing in one direction Heart Animation http://www.youtube.com/watch?v=H04d3r JCLCE http://www.youtube.com/watch?v=rBQOLi Fto6Q Blood Vessels 1. Arteries – (RED) Carries Blood Away from the Heart 2. Veins – (BLUE) Carry Blood Back to the Heart 3. Capillaries – Where exchange of nutrients takes place (O2, Waste, Etc…) Blood Vessels http://www.youtube.com/watch?v=CjNKbL _-cwA Circulationhttp://www.youtube.com/watch?v=PgI80U e-AMo&feature=related Capillarieshttp://www.youtube.com/watch?v=Q530H1 WxtOw Blood Pressure Definition: The Force of the Blood against the Walls of the Arteries Systole: Top Number of Blood Pressure (ventricles contracting) Diastole: Bottom Number of Blood Pressure (ventricles filled w/ blood) Blood - Function 1. Carries food and oxygen to all cells 2. Rids the body of Waste Blood - Components 1. Red Blood Cells - Erythrocytes 2. White Blood Cells - Leukocytes 3. Platelets - Thrombocytes 4. Plasma Red Blood Cells 1. Made in the Marrow of Bones 2. Carry Oxygen 3. Hemoglobin - The Protein that attracts O2 to the RBC - Prone to Defect/illnesses Blood Components http://www.youtube.com/watch?v=RsKZWqsUpw http://www.youtube.com/watch?v=CRh_d AzXuoU White Blood Cells 1. Made in the Marrow of Bones 2. Defend the Body against Disease Plasma 1. The Liquid part of Blood (55% of blood) 2. Mostly Water Blood Components Platelets 1. Aid in Blood Clotting 2. How Does Blood Clot? - Cut occurs. Platelets Activated. Platelets RUSH to the wound Fibrin is released (Spider Web) Web is formed over Wound Trapped Cells Harden and form a Scab PLATELETS = SPIDERMAN PLATELETS- STEP 1 Cut occurs…. Platelets Actived! PLATELETS – STEP 2 Platelets RUSH to the wound! PLATELETS- STEP 3 Fibrin is released (Spidey Web) PLATELETS – STEP 4 Web is formed over Wound. PLATELETS – STEP 5 -Trapped Cells Harden and form a Scab SPIDEY SAVES THE DAY Platelets http://www.youtube.com/watch?v=-bZUeb83uU&feature=related http://www.youtube.com/watch?v=vEmsaX A-go0 http://www.youtube.com/watch?v=JvOH5s kxqoA http://www.youtube.com/watch?v=M_YpLa WdBpk Blood Types A, B, AB, O Donor: Person who gives Blood Recipient: Person who receives Blood Clumping: Occurs when the blood types do not mix Blood Types A, B, AB, O Recipient D o n o r Mix? A B * AB O A Yes No YES No B No Yes YES No AB No No YES No *O YES YES YES YES *O = Universal Donor *AB =Universal Recipient BLOOD TYPES http://www.youtube.com/watch?v=MZ6_hSvjV_E BLOOD TYPE CHALLENGE http://answers.yahoo.com/question/index?qid=20080526202704AA o5bWa Really hard Logic/Blood Type Puzzle? Use the following information to predict each person's blood type. Bill can give blood to joe mike and sue Don can give blood to bob but not bill Bob can give blood to Mike but not Joe Tom can give blood to kelly, Sue, Don, and mike Kelly can give blood to sue and bob but not to tom sue cannot give blood to kelly joe can give blood to mike but not bob or sue mike can GET blood from sue and bill Joe does not have an A antigen Bill________ Bob_______ Don_______ Joe_______ Kelly______ Mike_______ Sue_______ Tom_______ Answer in terms of blood type (A, B, AB, or O) By the way, this may help: a can be given to a or ab b can be given to b or ab ab can be given to ab o can be given to anyone Heart Attack http://www.heartinfo.org/ms/animations/13/main.html http://www.youtube.com/watch?v=DGxS44-rcps&feature=related http://www.youtube.com/watch?v=0bLQj MaLilM&feature=related WARM-UP 2/11/11 Tell me as much as you can about one (or more) problems or diseases that affect the heart or blood?
