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

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.
