4 / 4 pts

The thymus secretes which of the following hormones? (Select all that apply.) Correct! Thymosin Correct! Thymopoietin TSH T T

Question 14

2.67 / 4 pts

Which of the following is a part of the nonspecific immune response system? (Select all that apply.) Correct! Normal flora Correct! Cytokines T cells B cells Correct Answer Interleukins Question 15

5 / 5 pts

Discuss how the body induces a fever. (Be sure to include the cells and regions of the body involved) Your Answer: A fever is related to an increase in temperatue brought on my the special type of cells called pyrogens that affect the hypothalamus (the body's temeperature regulator). Lysosomes are broken down and the enzymes are secreted by this process. The cells infected by the virus are destroyed by the enzymes from the break down of the lysosomes. White blood cells are also produced as a result of a fever and they also assist in the destruction of the pathogen.

During an infection, certain subtypes of interleukins called pyrogens reset the body’s thermostat in the hypothalamus. The temperature set-point during homeostasis (normal body temperature) is raised to create a fever. Question 16

5 / 5 pts

This is a localized response in the tissue, causing increased blood flow, redness, and pain. Your Answer: Inflammatory response The inflammatory response Question 17

3 / 3 pts

Match the cell with its best description. Has granules in the nucleus and is the most abundant of the white blood cells. Correct! Neutrophil Eosinophil Basophil Macrophage Monocyte

Question 18

4 / 4 pts

Match the cell with its best description. Select all that apply. Performs phagocytosis Correct! Neutrophil Correct! Eosinophil Correct! Basophil Correct! Macrophage Correct! Monocyte Question 19

3 / 3 pts

Match the cell with its best description. This cell is involved in the release of histamines and heparin. Neutrophil

Eosinophil Correct! Basophil Macrophage Monocyte Question 20

2.5 / 2.5 pts

Which type of immune cell continues to produce a small amount of antibody after the infection is over: Killer T cells Memory T cells Correct! Memory B cells Cytokines Question 21

2.5 / 2.5 pts

These cells contain a glycoprotein receptor as part of their cell coat:

Killer T cells T cells Correct! B cells Cytokines Interferons Question 22

2.5 / 2.5 pts

These cells contain an antigen receptor as part of their cell coat: Correct! T cells Memory B cells Interferons Plasma cells Neutrophils

Question 23

0 / 2.5 pts

What is FALSE concerning the MHC? Correct Answer These are antibody receptors found on only certain types immune cells. T cells recognize and destroy invading cells using the MHC. It is genetically determined and unique to each person You Answered Abnormal cells display a different MHC than healthy cells Question 24

5 / 5 pts

Discuss how antibody-mediated immunity defends the body against diseases. Give an example of what type of cell uses this form of immunity in the body. Your Answer: Antibody-mediated immunity involves the use of antibodies to destroy pathogens. The B cells have surface receptors that recognize the antigen and as a result antibodies are produced and this starts an immune response. The type of cells that use this form of immunity are the B-cells. B cells work through antibody-mediated immunity (humoral response) because B cells work against pathogens through the secretion of antibodies. Antibody- mediated immunity defends the body against pathogens through the secretion of antibodies. The antibodies bind to the pathogen, making it unable to cause further damage in the body and marking it for phagocytosis. Question 25

5 / 5 pts

What is graft rejection and why does it occur? Your Answer: Graft rejection occurs when the MHC on the surface of the graft rejects the donor. It sees the graft as foreign to the person's body. Graft rejection is the rejection of a transplanted organ by an organ donor. Tissue grafts and organ transplants most often originate from another person's body. The MHC on the surface of the graft are recognized by the host body as a foreign pathogen. Question 26

3 / 3 pts

Multiple sclerosis is an autoimmune disease where the immune cells attack the ___________. Your Answer: myelin sheath Myelin sheath Question 27

2 / 3 pts

A patient is admitted to the ER with hives and difficulty breathing. What is most likely happening? Your Answer: This is an allergic reaction. The capillaries have dilated and this causes the appearance of red bumps on the surface of the skin. The allergic reaction has also caused bronchoconstriction hence why he was having trouble with breathing. Anaphylaxis Anaphylaxis Question 28

4 / 4 pts

Look at the patient in the picture below. This patient does not want further medical help. Name two concerns you discuss with your patient if she does not continue treatment.
