Lymphatic System & Immunity

What are two major functions of the lymphatic system

• Transport nutrients, oxygen and other molecules to cells and carry waste away from cells

• Regulate blood fluid levels and help fight pathogens, toxins & cancer cells

• To provide structure and help with movement

Your lymphatic system plays a vital supporting role to what two other systems?

• Nervous & Integumentary

• Skeletal & Muscular

• Cardiovascular & Immune

The watery fluid that flows through your lymphatic vessels is called _______________.

• lymph

• blood

• interstitial fluid

• plasma

What lymphatic system organ serves as a checkpoint that monitors and cleanses the lymph as it filters through?

• kidney

• adrenal gland

• lymph node

• liver

The lymphatic system recovers about 3 liters of blood fluid per day and returns it to the circulatory system. What problem would arise if this did NOT happen?

• High Blood Pressure

• Low Blood Pressure

• Normal Blood Pressure

Disease causing agents such as viruses, bacteria, fungi and protozoans are called what?

• lymphocytes

• pathogens

• macrophages

• prokaryotes

Which of the following is an example of an innate (nonspecific) defense of your immune system?

• inflammation in response to infection

• B Cells producing antibodies

• Macrophage displaying a digested antigen

• T Cells destroying bacteria

Type of immune system cell that interacts directly with antigens, producing the cellular immune response. This type of cell kills infected cells directly.

• B Cell

• Memory B Cell

• T Cell

• Helper T Cell

Type of immune system cell that is involved in the humoral immune response by producing and secreting antibodies.

• B Cell

• Memory B Cell

• T Cell

• Helper T Cell

Type of immune system cell that stimulates both cell mediated and humoral immune responses by activating B Cells to produce antibodies and activating T cells to kill infected cells.

• B Cell

• Memory B Cell

• T Cell

• Helper T Cell
