Questions and Answers
- 1.
Which one of these options is an external barrier to foreign substances?
- A.
Skin
- B.
Nasal membranes
- C.
Urinary tract
- D.
All of the above
- E.
None of the above
Correct Answer
D. All of the aboveExplanation
All of the options mentioned (skin, nasal membranes, urinary tract) act as external barriers to foreign substances. The skin acts as a physical barrier, preventing the entry of pathogens and other harmful substances. Nasal membranes produce mucus and have tiny hair-like structures called cilia, which trap and remove foreign particles from the air we breathe. The urinary tract, including the urethra, bladder, and ureters, helps to flush out toxins and pathogens through urine. Therefore, all of these options serve as external barriers to foreign substances.Rate this question:

When one of these barriers are penetrated what is activated?
- A.
Unnatural immune system
- B.
Proactive immune system
- C.
Natural immune system
Correct Answer
C. Natural immune systemExplanation
When one of these barriers is penetrated, the natural immune system is activated. The natural immune system is the body's first line of defense against pathogens and foreign substances. It includes physical barriers like the skin and mucous membranes, as well as immune cells such as white blood cells that can recognize and destroy harmful invaders. Activation of the natural immune system triggers a cascade of immune responses, including inflammation and the production of antibodies, to eliminate the threat and protect the body from further harm.Rate this question:

What response is initiated when foreign microorganisms penetrate the external barriers?
- A.
Mandatory biological response
- B.
Inflammatory response
- C.
Schweinbergs response
Correct Answer
B. Inflammatory responseExplanation
When foreign microorganisms penetrate the external barriers, the body initiates an inflammatory response. This response is a protective mechanism that involves various immune cells and chemical mediators. It is characterized by redness, swelling, heat, and pain at the site of infection. The inflammatory response aims to eliminate the invading microorganisms and repair any tissue damage. It also helps in recruiting immune cells to the site of infection and enhancing the overall immune response.Rate this question:

Lymph nodes and vessels circulate fluid called________ that contains proteins, glucose, monocytes, and lymphocytes?
- A.
Blood
- B.
Plasma
- C.
Lymph
Correct Answer
C. LymphExplanation
Lymph nodes and vessels circulate fluid called lymph that contains proteins, glucose, monocytes, and lymphocytes. Lymph is a clear fluid that is similar to plasma, but it does not contain red blood cells. It is formed from the interstitial fluid that surrounds the body's tissues and is collected by lymphatic vessels. Lymph plays a crucial role in the immune system, as it transports immune cells and substances to fight against infections and diseases.Rate this question:

The _______ and _________ systems work together together to guard the body against pathogens and to eliminate them if they manage to pass through the outer barriers,
Correct Answer
immune and lymphExplanation
The immune and lymph systems work together to protect the body from pathogens. The immune system is responsible for recognizing and attacking foreign substances, such as bacteria or viruses, while the lymphatic system helps to circulate immune cells and remove toxins and waste from the body. By collaborating, these systems ensure that the body is able to defend itself against harmful invaders and maintain overall health.Rate this question:

_________immunity is nonspecific immunity that is in humans when they are born?
- A.
Acquired
- B.
Natural
- C.
Monocygotic
Correct Answer
B. NaturalExplanation
Natural immunity refers to the innate immune response that is present in humans from birth. This type of immunity is nonspecific, meaning it provides a broad defense against a wide range of pathogens without the need for prior exposure or immunization. Natural immunity includes physical barriers like the skin and mucous membranes, as well as cellular and chemical components such as phagocytes and antimicrobial proteins. Unlike acquired immunity, which develops over time in response to specific pathogens, natural immunity is already present at birth and provides immediate protection against various infections.Rate this question:

- 7.
The ____________ response alone may be adequate in killing the invading organism by creating a hostile environment?
Correct Answer
inflammatoryExplanation
The inflammatory response is a natural defense mechanism of the body that helps to eliminate invading organisms. It involves the release of various chemicals and immune cells to the site of infection or injury. These chemicals and cells create a hostile environment for the invading organism, inhibiting their growth and promoting their destruction. Therefore, the inflammatory response alone may be sufficient to kill the invading organism.Rate this question:
- 8.
The ________ response is a remarkable series of complex chemical and mechanical activities that take place in the body?
Correct Answer
immuneExplanation
The immune response refers to the body's complex chemical and mechanical activities that occur in response to foreign substances or pathogens. It involves various components of the immune system, such as white blood cells, antibodies, and cytokines, working together to identify and eliminate these threats. This response is crucial for protecting the body from infections and maintaining overall health.Rate this question:
- 9.
If there is a lack of an appropriate response to an antigen what would the patient have?
- A.
Aspergers
- B.
Immune deficiency
- C.
Autologous immune disease
Correct Answer
B. Immune deficiencyExplanation
If a patient lacks an appropriate response to an antigen, it means that their immune system is not functioning properly or is deficient. This can lead to a weakened immune response and an increased susceptibility to infections and diseases. Therefore, the correct answer is immune deficiency.Rate this question:

- 10.
When the body produces an immune response to a "self" cell or tissue the disorder is autoimmune disease?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
An autoimmune disease occurs when the body's immune system mistakenly attacks its own cells or tissues, considering them as foreign invaders. This immune response leads to inflammation and damage to the affected organs or tissues. Therefore, the statement "When the body produces an immune response to a 'self' cell or tissue, the disorder is an autoimmune disease" is true.Rate this question:
