2C - Prove Mastery (blood and lymph)

The function of the tonsils is to:

• trap and remove pathogens that enter the throat
• filter and cleanse the blood of pathogens and debris
• program lymphocytes to recognize specific pathogens or cells
• capture and destroy bacteria in the gut
• filter and cleanse the lymph of pathogens and debris

What is the general function of the cell at the tip of the pointer?

• destroys pathogens and protects you from illness and infection
• carries oxygen from the lungs to body tissues
• helps to stop bleeding
• If a person's blood is AB positive, this means that:

In the lymph node, B cells are found in the:

• cotex
• medulla
• afferent lymphatic vessel
• efferent lymphatic vessel

The function of the spleen is to:

• filter and cleanse the blood of pathogens and debris
• program lymphocytes to recognize specific pathogens or cells
• trap and remove pathogens that enter the throat
• capture and destroy bacteria in the gut

The lymph is NOT transported back to the cardiovascular system by:

• milking action of the skeletal muscles
• pressure changes in the thorax during breathing
• lymphatic pumps interspersed in the lymph vessels
• surrounding rhythmic smooth muscle contractions
• valves in larger lymphatic vessels

What is lymph?

• the plasma portion of blood found in the blood vessels
• the cellular portion of blood found in the blood vessels
• the fluid portion of blood that has leaked out from the bloodstream
• the serum portion of blood found in the blood vessels
• the excess fluid portion in blood that has leaked out from the lymphatic capillaries

The leukocytes responsible for phagocytizing small particles are known as:

• eosinophils
• neutrophils
• lymphocytes
• basophils

Adaptive immunity is dependent upon exposure to specific antigens such as getting a flu shot exposes you to the flu virus allowing the body to learn how to "fight" the flu virus.

• True
• False

When monocytes migrate out into the tissue spaces they are called __.

• macrophages
• glial cells
• chondrocytes
• platelets

Which WBC is properly matched with its function?

• neutrophil- phagocytizes parasites and controls inflammation
• monocyte- releases heprin and histamine
• lymphocyte- provides specific immunity protection
• basophil- may leave the tissues to phagocytize large particles
