The document summarizes the key components and functions of blood and the lymphatic system. It discusses how blood transports nutrients, gases, and waste, and is composed of plasma, red blood cells, white blood cells, and platelets. It then explains the production of blood cells, the roles of each blood component, blood types, and the lymphatic system's role in immunity and defense.

Blood and Lymphatics Jessalynn Medina
Blood • A critical agent of transportation of nutrition, gases, and waste to all parts of the body. • Parts attach to red blood cells or dissolve in plasma. • White blood cells fight infection and disease. • Platelets initiate blood clotting.
Blood Components • Blood is a mixture of • Plasma • Formed Elements • Erythrocytes= Red Blood Cells • Leukocytes= White Blood Cells • Platelets
Production • Hematopoiesis= blood cell production by red bone marrow • Red bone marrow most abundant in children • Adults have more yellow marrow than red
Plasma • 55% of adult whole blood supply • 90-92% is water • 8-10% is dissolved substances: • Plasma proteins • albumin-transport fatty substances • Globulin- type of antibody • Fibrinogen- blood clotting protein • Ca, K, Na, glucose, amino acids, and fats are also transported via plasma
Erythrocytes • Red Blood Cell • Not a true cell- no nucleus • Hemoglobin creates red color • this is what picks up oxygen from lungs to deliver to tissue. • Lifespan of 120 days • Spleen removes worn-out/damaged RBC
Leukocytes • White Blood Cells • True Cell • Provides protection against pathogens like bacteria and viruses
5 Types of Leukocytes • Granulocytes- granules in cytoplasm • Basophiles- histamine and heparin release • Eosinophils- destroys parasites- high in allergic reactions • Neutrophil- phagocytize foreign and damaged cells • Agranulocytes- no granules • Monocyte- phagocytize foreign and damaged cells • Lymphocytes- several roles in immune response
Platelets • Modern term thrombocyte= smallest of all blood elements • Not whole cells but formed when cytoplasm of larger cell shatters into fragments. • Critical for blood clotting- hemostasis • Agglutinate- clump together when blood vessel is cut
Blood Types • Blood differs because of presence of antigens or markers on RBC • Type: • A • B • AB= universal recipient • O= universal donor
Rh- Factor • If present, then Rh+ (Type A+, B+, AB+, O+) • Not present then Rh- (A-, B-, AB-, O-) • Rh + can have blood transfusion for positive and negative Rh • Rh- can only have transfusion for negative Rh-
Lymphatics • System composed of: • Lymphatic Vessels • Lymph Nodes • Spleen • Thymus • Tonsils • Fluid in system is called lymph • Serves at body primary defense system
Network • Lymphatic Vessels- network of ducts, one way system • Lymph Nodes- small organs/ glands that acts like a filter to remove pathogens and debris • Tonsils- each side if throat. Lots of leukocytes. Filters to protect body digestive and respiratory. • Spleen- filters blood • Thymus Gland- development of immune system
Immunity • Body ability to defend itself from pathogens • Natural immunity/ innate immunity • What the body already is equipped with- ie macrophage • No exposure to disease or pathogen • Acquired immunity • Body response to specific pathogen
