Touring the Systems

of the Human Body

First Stop:Dramatic Lymphatic Island

• Also know as the Lymphatic System, Its Purposes:

• It is the body's network of organs, ducts, and tissues that filter harmful substances out of the fluid that surrounds body tissues.

• Defends the body against germs like viruses, bacteria, and fungi that can cause illnesses.

• Collects extra lymph fluid and returns it to the bloodstream.

Important Destination Spots

(Structures and Functions: Examples)• Let’s check out the Node-A-Coaster

– Lymph nodes: located in the neck; filters bacteria, viruses or dead cells out of lymph; releases white blood cells.

• The Spleen Machine– largest lymph gland organ; located in

upper left side of abdomen; filters the blood and releases white blood cells.

• Tonsils – etc.• Thymus – etc.

Exciting Activities• Fever Flight – Like Sentries and

Archers who stand on the castle wall, our bodies lymphatic system uses a second line of defense to keep us safe, which includes fever and inflammatory response as nonspecific defenses against invading bacteria and viruses.

Imports & Exports of the System

• Pus Busters:– When the body detects some sort of foreign

infection, it immediately begins a response to neutralize the invader and limit damage to the system. White blood cells, or leukocytes, are the cells responsible for immune response in the body, and are produced in the marrow of bones. The majority of these white blood cells are a type known as neutrophil, which are tasked with attacking foreign bacteria and fungi.

Dangers/Special Precautions Visitors Might Encounter

Caution! Glandular Swells: •Swollen lymph nodes may signal an infection.

•There are several groups of lymph nodes, which are small, bean-shaped, soft nodules of tissue. The ones most frequently enlarged or swollen are found in the neck, under the chin, in the armpits, and in the groin.

Package Deals:How each destination interacts with another.

Circulatory Overload:

a) Lymphatic Vessels Resemble the Veins and Capillaries of the Circulatory System

b) The Lymphatic System Returns Fluids to the Bloodc) The Lymphatic System Transports Fats from the

Small Intestine to the Blood d) The Lymphatic System Helps Defend the Body

Against Disease by sending White Blood Cells (Warriors) to the field of invasion.

Translation of Language(Define the terms)

• Lymph - is the fluid that circulates throughout the lymphatic system.

• Nodes - a small ball or an oval-shaped organ of the immune system, distributed widely throughout the body including the armpit and stomach and linked by lymphatic vessels.

• Etc.

Answering S7L2.d.• For each destination, you need

to explain how the destination (system) helps to meet the needs that cells have for (oxygen, food (nutrients), and waste removal.
