LAB - D313 Immune System/Lymphatic
UPDATED ACTUAL Exam Questions and
CORRECT Answers
As the first phagocytes to arrive at the site of inflammation, ____________ secrete cytokines to
attract other immune cells to the site of infection. - CORRECT ANSWER - Neutrophils
type of cell that has the ability to ingest, and sometimes digest, foreign particles, such as bacteria,
carbon, dust, or dye - CORRECT ANSWER - phagocyte
Which structure of the lymphatic system removes dead red blood cells from the blood? -
CORRECT ANSWER - Spleen
___ is responsible for the production and maturation of blood cells. This includes white blood
cells. The immune system utilizes these cells to protect the body against infection. Bone marrow
also helps the body maintain homeostasis. - CORRECT ANSWER - bone marrow
____ is where precursor T-cells develop, differentiate, and multiply. They gain their angin
specificity and immune tolerance to the body's own tissues. - CORRECT ANSWER - Thymus
gland
___ are known for filtering, cleansing, and activating immune responses. This helps the body
recognize and fight infections. - CORRECT ANSWER - Lymph nodes
Which cells are activated by interferons and cytokines and destroy cells infected with a wide
range of viruses and cancers? - CORRECT ANSWER - Natural killer cells
This is the correct answer because natural killer cells are activated by interferons and cytokines
and destroy cells infected with a wide range of viruses and cancers.
, ____ are large phagocytic cells that can engluf secretions of damaged tissue and microbes.
Wandering macrophages are dispersed through the body, even with no infection. Fixed
macrophage cells develop and remain fixed in special organs. They are named according to
location. - CORRECT ANSWER - macrophage cells
____ cells quickly arise at the site of inflammation to engulf microbes and differentiate into
macrophages and dendric cells. - CORRECT ANSWER - Monocyte
____ cells are the first phagocyte to arrive at the site of inflammation. They secrete cytokines to
attract other immune cells to the site of infection. Phagocyte microbes release toxin granules.
They also release lysomal enzymes that are responsible for inflammation and tissue damage. -
CORRECT ANSWER - Nuetrophil
What are the primary cells of the adaptive immune response? - CORRECT ANSWER -
Lymphocytes cells
This is the correct answer choice because lymphocytes are considered primary cells of the
adaptative immune response.
Antimicrobial substances form part of the second line of defense against a pathogen. Which
substances are antimicrobial? Select three answers. - CORRECT ANSWER - complement
system
Interferon
Iron-binding proteins
Why does the human body have natural antibodies? - CORRECT ANSWER - To provide
immunity to environmental bacteria
Which type of immune cell is most directly effective against bacteria? - CORRECT
ANSWER - Complement cell
