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 CellsMature 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 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.
