U6.C2: Lymphatic System Quiz

Match the following

• lymph

• Protein-containing fluid that moves through lymphatic vessels to return fluids that have leaked from the vascular system back to the blood

• lymph nodes

• Networks of drainage vessels that collect and return excess interstitial (tissue) fluid to the blood

• lymphatic trunk

• Small organs that act as checkpoints to filter the lymph as it moves through the body

• lymphatic vessels

• Where lymphatic vessels unite and drain large areas of the body

Match the following

• lacteals

• Type of lymphocytes that directly attack invading substances and manage the immune system

• MALT (mucosa-associated lymphoid tissue)

• Set of lymphoid tissues located in mucous membranes throughout the body that prevent pathogens from penetrating mucous membranes and are the site of lymphocyte activation and proliferation

• T cells

• Type of lymphocytes that secrete antibodies into the blood

• B cells

• Specialized lymphatic capillaries that carry absorbed fat from the intestines to the blood

Reorder the following to demonstrate the movement of lymph from the lymphatic capillaries.

• lymphatic duct

• lymphatic trunk

• lymphatic capillaries

• lymph notes

• heart

these are interwoven with blood capillaries between tissue cells, but are more permeable and thus can more easily take in larger particles like proteins, cell debris, pathogens, and cancer cells.

• lymphatic capillaries

• blood capillaries

• right lymphatic duct

• thoracic duct

NGSS.MS-LS1-3

takes lymph from right upper limb, right side of head, and thorax to the heart via the internal jugular vein

• lymphatic capillaries

• blood capillaries

• right lymphatic duct

• thoracic duct

takes lymph from everywhere else to the heart via the subclavian vein

• lymphatic capillaries

• blood capillaries

• right lymphatic duct

• thoracic duct

Organize these options into the right categories

Groups:

(a) Primary Lymphoid Organs

,

(b) Secondary Lymphoid Organs

,

(c) MALT

• MALT

• appendix

• where B cells are made mature

• where mature lymphocytes are activated

• cells are made here to defend us against pathogens when activated as an immune response

• thalmus

• where T cells are made

• can cleanse lymph and activate the immune system

• lymph notes

• tonsils

• Peyer's patches

• red bone marrow

• spleen

Summarize the roles of the thymus, spleen, tonsils, Peyer’s patches, and appendix in the lymphatic and/or immune systems.

• spleen

• where T cells mature so that they can actually defend us against pathogens when activated in an immune response

• Peyer's patches

• cleanses blood and removes aged/defective red blood cells, debris, and foreign substances while also activating and proliferating lymphocytes

• thymus

• gathers and tries to remove pathogens from food or inhaled air before they can enter the GI tract or lungs

• appendix

• prevent bacteria from breaching the intestinal wall and generating “memory” lymphocytes for establishing long-term immunity

• tonsils

• monitor intestinal bacteria populations in the ileum and prevent the growth of pathogenic bacteria
