13.  Which type of immunity occurs as a response to illness or vaccination?

14.  A decrease in ________ secretion causes a lowering of blood volume and blood pressure and an increase is body osmotic pressure.

15.  Which of the following is not one of the three unique characteristics of the immune system?

16.  Which of the following is an age related change associated with the immune system?

17.  All of the following are ways to minimize the undesirable effects of aging on our immune system, except what?

18.  Which of the following statements regarding antibodies is true?

19.  What are the unique characteristics of the immune system?

20.  Which type of immune system cell is formed from an unspecialized lymphocyte because of the influence of the thymus on the lymphocyte?

Multiple sclerosis Rheumatoid arthritis Myasthenia gravis Crohn's disease

Explanation / Answer

11.

Myasthenia gravis causes autoimmune damage to receptors for acetylcholine at the neuromuscular junction.

12.

The number of memory cells increase with age due to the fact the body has been exposed to numerous antigens throughout life.

13.

Acquired active type of immunity occurs as a response to illness or vaccination ( acquired passive occurs when body is attacked again by the disease).

14.

A decrease in Anti Diuretic Hormone or ADH causes a lowering of blood volume and blood pressure and an increase is body osmotic pressure.

15.

Sensitivity is not a characteristic of human immune system

16.

The rate of B-cell production decrease with age

17.

Seek early treatment when ill is not a way to minimize undesirable effects of age on our immune system because if we seek early treatment than our immune system won't be able to fight against the infection but we are already providing a medication thus not allowing our immune system to fight against the disease.

18.

IgA activates the complement system( but it is a poor activator)

19.

self recognition, specificity, memory are three unique characteristics of immune system

20.

T-cell is formed from an unspecialized lymphocyte because of the influence of the thymus on the lymphocyte
