1. Liquid connective tissue that is pumped by the heart & flows through vessels in your body River of Life Blood and Lymphpage 545 Plasma Red Blood Cells White Blood Cells Platelets The liquid part of blood 90 % water/10% dissolved materials Oxygen, glucose, fats, vitamins, minerals, chemical messengers What is blood? Name the 4 components of blood--- Plasma---- What is the make up of plasma? What does plasma carry? What are the functions of the protein molecules in plasma? What is the color of plasma and why? • Regulates water in blood • Helps fight disease • Help form blood clots • Give plasma yellow color Yellow---Due to protein molecules

2. RBC look like disc with a pinched center--- jelly doughnut---has NO Nucleus Pick up oxygen in the lungs and deliver to cells Enables them to squeeze single file through capillaries Describe a Red Blood Cell (Erythrocyte)--- What is the function of your RBC? Why do RBC need to be flexible? What is hemoglobin and what is its function? When does a red blood cell become bright red? Approximately how long do RBC live? Where are red blood cells produced? Draw a RBC An iron-containing protein which makes up most of the RBC that binds with oxygen---allows RBC to carry oxygen When hemoglobin binds with oxygen Approximately 120 days or 4 months Marrow of Bones

3. Cells in blood that fight disease 5 types---some recognize disease-causing organisms and alert body it has been invaded--- some produce chemicals to fight invaders, some surround and kill organisms White Blood Cells (Leucocytes)---- What do WBC do? How long do WBC live? What is the ratio of RBC to WBC? When would your WBC count rise? What structure do WBC have that mature RBC do not? What system do the WBC work With? How do WBC compare to RBC? Days, Months even Years 1 WBC to every 500-1000 RBC When your body is fighting an infection Nucleus Immune System Fewer in number---Larger in size--- Have a nucleus---like RBC made in marrow

4. Component (Part) of the blood that function during blood clotting When blood vessel cut they collect at site of wound Platelets (Thrombocytes)— - What is the function of a platelet? What is fibrin? Explain how a blood clot forms---- What is a scab? Why is this clotting process important? Name the living components of blood--- Name nonliving components of blood--- Protein that aids in blood clotting---weaves net Vessel cut---platelets collect and stick to wound---Platelets release chemicals---produces the protein fibrin---fibrin weaves net across wound—traps blood cells---blood clot forms Dried Blood Clot on Surface of Skin Blood loss is harmful/Keeps microorganisms out RBC----WBC ----Platelets Plasma and all dissolved mineral and materials carried by blood

6. Blood Types An Austrian American physician who discovered the 4 blood types/1900”s Who is Karl Landsteiner? Transfusion--- What do blood markers determine and where re they found? “Type and Cross”? What are the 4 Blood Types? Universal Donor--- Universal Recipient--- What would happen if an Rh negative received Rh positive blood? Blood taken from one person and put in another Proteins on red blood cells that determine blood type. Determine patients blood type and cross match it with donated blood A B AB O Type O Blood Type AB Clumping of blood proteins causing death

7. Lymph A network of Vein-like vessels that returns the fluid to the bloodstream What is your lymphatic system? Where does lymph come from? Lymph consists of---- Lymphatic vessels are part of which system? Where does lymph empty? Role of lymph nodes? What would a swollen lymph node indicate? Fluid from blood that leaks out from the capillaries Water----dissolved materials---white blood cells Cardiovascular System Into large veins in Chest---now back in circulatory system These knobs of tissue act to filter lymph, trapping bacteria and disease causing organisms Your body is fighting infection— Bacteria or virus
