Blood System Overview Blood circulates through blood vessels to: transport oxygen, nutrients, and hormones to body cells carry away waste Plasma – liquid portion of the blood

Blood System Overview Cellular components suspended in the plasma: (continued) Cellular components suspended in the plasma: erythrocytes – red blood cells leukocytes – white blood cells platelets – cell fragments essential for blood clotting Serum – portion of the plasma that remains after the clotting process

Components of the Blood p277 278

Lymphatic System Overview p281 Protects the body by filtering microorganisms and foreign particles Maintains the body’s internal fluid environment Responsible for carrying fats away from digestive organs

Lymphatic System

Lymphatic Organs thymus spleen primary gland of the lymphatic system produces T lymphocytes to help immune response spleen located between stomach and diaphragm filters out aging blood cells removes cellular debris

Lymphatic Structures lymph fluid that is circulated through lymph vessels lymph capillaries (where have we seen capillary before?) draw lymph from tissues to lymph vessels lymph vessels circulate lymph to the lymph nodes

Lymphatic Structures lymph nodes (think nodule) (continued) lymph nodes (think nodule) oval structures that filter lymph located in the cervical, axillary, and inguinal regions lymph ducts (think air duct for an air conditioner) collecting channels that carry lymph from the lymph nodes to the veins

Immunity Process of disease protection induced by exposure to an antigen antigen – substance that, when introduced into the body, causes formation of antibodies against it (think: generates an immune response) antibody – substance produced by the body that destroys or inactivates an antigen

Types of Immunity Active immunity long lasting protects the body against a future infection as a result of natural antibodies developed following a natural infection (artificial antibodies – after administration of a vaccine)

Types of Immunity Passive immunity short lasting (continued) Passive immunity short lasting conveyed naturally through the placenta to a fetus (the mother passes it along to the baby) conveyed artificially by injection of a serum containing antibodies
