Blood and Lymphatic System Blood –Components –Blood types –Function Lymphatic system –Parts –Function

Blood Connective tissue –Connects different organ systems –Produced in long bones

Blood - Parts Red Blood Cells (RBC) White Blood Cells (WBC) Platelets Plasma

RBC and Oxygen RBC take oxygen to all parts of your body. –Hemoglobin

Platelets Pieces of larger cells found in Bone Marrow/Blood Stream

Plasma straw-colored liquid in blood about 55% - total blood volume

White blood cells Blood cells that help fight pathogens

B-cell

Killer T-cells Cancer cells

Blood Types Four types of blood cells, has chemicals on the surface.

Lymphatic System Vessels Bone Marrow Lymph Nodes Thymus Spleen Tonsils

Vessels Lymph capillaries Lymph Vessels

Lymph Capillaries Smallest vessels Absorbs lymph and particles between cells.

Lymph Vessels Skeletal muscles squeeze lymph through lymphatic system Valves (body opening)

Lymph nodes Area where lymph collects WBCs in high numbers kill pathogens

Lymph Nodes Pathogens Dead cells Lymphocytes Killer T cells B cells

How does this all work together?

Pathogens Virus Bacteria Fungus Parasite Prion

Bone Marrow Red & White blood cells Lymphocytes: WBC that fights pathogens

Red Blood Cells

White Blood Cells Different types of white blood cells fight pathogens

White Blood Cells

Lymphocytes

Platelets Small At cut – form fibers Causes clots to form

Pathogen

Lymphocytes A white blood cell that helps your body fight pathogens.

Immature Cells Produced in bone marrow Develop farther in the thymus gland

Thymus T cells finish development in the thymus gland.

Immature Cells

Matured Cells Thymus produces lymphocytes ready to fight infection.

Mature Cells

Killer T Cells KT cells surround and destroy pathogens.

Killer T Cell

B Cells B cells produce antibodies to destroy cells.

B Cells

Dead Cells Red or white cells that have fought pathogens then exploded.

Dead Cell

Organs of the Lymphatic System Thymus Spleen Tonsils

Spleen Largest lymphatic organ Stores and produces lymphocytes Spongy

Red and white pulp White pulp: Produces white blood cells Red: Removes damaged cells

Red PulpWhite Pulp White Pulp Red Pulp

Tonsils Small masses of tissue Infection Located from mouth to pharynx

Infection Tonsils when infected may become swollen and very sore.
