A | B |
Interferons prevent viral infection by | causing neighboring cells to produce antiviral proteins |
Phagocytosis is | endocytosis and destruction of cells |
An antigen is | a large molecule that resist infection |
Antibodies are | produced in response to an antigen and effective against extracellular antigens such as bacteria, viruses, protozoans, fungi, parasites, and toxins |
The symptoms of local and systemic inflammation | redness, heat, swelling, pain, loss of function |
Complements provide protection from bacteria by | forming a membrane attack complex (MAC), attaching to the surface of bacterial cells, stimulating phagocytosis, and attracting immune system cells to site of infection and promoting inflammation |
Put the events that take place during an inflammatory response in order | bacteria attack, tissue becomes damaged, chemical mediator, increased blood flow, increased number of white blood cells, bacteria are destroyed, bacteria gone, tissue repaired |
The function of Natural Killer (NK) cells is | to recognize and kill classes of host cells |
Neutrophils and macrophages' primary function is | to phagocytize cells |
Adaptive Immunity is | specific immunity, is the ability to remember previous encounters with particular substance, and has the ability to recognize a particular substance |
Innate Immunity is | nonspecific resistance involving mechanical and chemical defense; and cellular and inflammatory responses |
The thymus is located | in the middle of the superior portion of the thoracic cavity |
The spleen is located | on the left side of the body in the abdominal cavity |
The overall function of the tonsils is | to help protect from bacteria |
The correct location of each of the tonsils | pharyngeal, top; palatine, side; lingual, tongue |
The lymph returns to the blood through the | veins |
What are the three functions of the lymphatic system | fluid balance, fat absorption, defense |
Which are the organs of the lymphatic system? | thymus, spleen, lymph nodes, tonsils |
lymph is | A clear yellowish fluid found in the lymph vessels with solutes from plasma and other cells |
The structure in lymphatic vessels that ensures one-way flow | valves |
The right lymphatic duct drains | the right side of the head, right upper limb, and right thorax |
The thoracic duct drains | the entire left side of the body and the lower limbs of the right side of the body |
The functions of the lymph | filter lymph and activate the immune system |
The functions of the spleen | destroys defective RBCs, detects and responds to foreign substances, and is a limited reservoir for blood |
The function of the thymus is | site of production and maturation of T cells |
The main components of innate immunity are | mechanical mechanisms, chemical mediators, cells, and inflammation |
