1 Class StarterWhat is the difference between arteries, veins, and capillaries?What is the atherosclerosis?What are three effects of this condition?What are the 4 parts that make up the blood?
3 Blood BasicsBlood is a type of connective tissue containing both dissolved substances and specialized cellsCollects oxygen from lungs, nutrients from the digestive system, and wastes from the tissues
5 Blood PlasmaStraw colored liquid made of 90% water and 10% dissolved gases, salts, nutrients, enzymes, hormones, wastes, and plasma proteinsPlasmaPlateletsWhite blood cellsRed blood cells
6 Plasma Proteins Three different types of plasma proteins Albumins Helps regulate osmotic pressure and blood volumeTransports substance (fatty acids, hormones, and vitamins)GlobulinsSome fight viral and bacterial infectionsFibrinogenResponsible for ability to clot blood
7 Red Blood Cells Erythrocytes Most numerous blood cell in the blood Do not contain nuclei or other organelles when they are matureMost numerous blood cell in the bloodProduced in the bone marrowTransport oxygenContains hemoglobinIron containing protein thatoxygen binds toGives blood its color
8 Blood TypesEach individual has a blood type that is determined by the presence or absence of proteins called antigens on the red blood cellBlood types includeA blood – have the A antigen on the RBCB blood – have the B antigen on the RBCAB blood – has both the A and B antigen on the RBCO blood – does not have either A or B antigens on the RBC
10 Blood TransfusionsWhen serious injury occurs and blood is needed to be injected into patient, blood types must match or be compatibleIf not compatible, the blood cells will react in a process called agglutinationBlood cells stick together
11 Review Questions What makes up the majority of the blood? What the 3 plasma proteins and their function?Who can receive blood from an A blood type donor?Who can donate blood to a B blood type person?Who can receive blood from anyone?Who can donate blood to anyone?
12 White Blood Cells Leukocytes Produced in the bone marrow Contain nucleiCan be found outside ofthe circulatory system inthe lymphatic systemProduced in the bone marrowGuard against infection, fight parasites, and attack bacteria
13 Platelets and Blood Clotting Platelets are cell fragmentsthat contain clotting factorCome in contact with edgesof broken vessels and begin tostick togetherRelease clotting factor whichstarts the blood clotting processThromboplastin, prothrombin, thrombin, and fibrinogen are all used in clotting blood
14 Break in Capillary Wall Clumping of PlateletsPlatelets clump at the site and release thromboplastin. Thromboplastin converts prothrombin into thrombin..Clot FormsThrombin converts fibrinogen into fibrin, which causes a clot. The clot prevents further loss of blood..Break in Capillary WallBlood vessels injured.
15 HemophiliaGenetic disorder that results from a defective protein in the clotting pathwayPeople cannot produce blood clotsCan be treated with injections of the missing clotting factor
16 Lymphatic SystemThe lymphatic system is a system of vessels, nodes, and organs that collect any fluid lost by the bloodIt returns this fluid (lymph) back into the circulatory system in the superior vena cavaMain organs of the lymphatic system are the thymus and the spleen
