- E.
Muscle contractions and pressure changes caused by breathing
Correct Answer
E. Muscle contractions and pressure changes caused by breathingExplanation
Muscle contractions and pressure changes caused by breathing are responsible for moving lymph fluid through the body. When muscles contract, they squeeze the lymphatic vessels, helping to push the fluid along. Additionally, when we breathe, the pressure changes in our chest cavity create a suction effect that pulls the lymph fluid towards the heart. These combined actions of muscle contractions and pressure changes caused by breathing facilitate the circulation of lymph fluid throughout the body.Rate this question:

Which substance below uses pH to keep microbial invaders out of the cervical region?
- A.
Urine
- B.
Stomach
- C.
Mucous
- D.
Vaginal secretions
Correct Answer
D. Vaginal secretionsExplanation
Vaginal secretions use pH to keep microbial invaders out of the cervical region. The vagina has an acidic pH, typically ranging from 3.5 to 4.5, which creates an inhospitable environment for many harmful bacteria and fungi. This acidic pH is maintained by the presence of lactic acid-producing bacteria, which help to keep the vaginal ecosystem balanced and prevent the overgrowth of harmful microorganisms. By maintaining a low pH, vaginal secretions act as a natural defense mechanism against potential infections in the cervical region.Rate this question:

A substance that the immune system recognizes as foreign
- C.
A cell that attacks microbes
- D.
A symptom of an allergic attack
- E.
A and C are correct
Correct Answer
B. A substance that the immune system recognizes as foreignExplanation
An antigen is a substance that the immune system recognizes as foreign. When an antigen enters the body, the immune system produces specific proteins called antibodies to neutralize or eliminate the antigen. This immune response is crucial for defending the body against infections and diseases. Antigens can be molecules from pathogens such as bacteria or viruses, as well as substances from allergens or transplanted tissues. By recognizing and responding to antigens, the immune system plays a vital role in maintaining the body's overall health and protecting it from harm.Rate this question:

Self tolerance is...
- A.
The ability to tolerate illness
- B.
The ability to withstand a fever
- C.
The ability to allow certain pathogens to exist in the body
- D.
The ability to turn immunity on or off
- E.
The immune systems ability to recognize tissues as being self
Correct Answer
E. The immune systems ability to recognize tissues as being selfExplanation
Self tolerance refers to the immune system's ability to recognize and distinguish its own tissues as "self" and not mount an immune response against them. This is crucial for maintaining normal bodily functions and preventing the immune system from attacking its own tissues, which can lead to autoimmune diseases. Self tolerance ensures that the immune system only targets foreign substances, such as pathogens, while leaving the body's own healthy tissues unharmed.Rate this question:
-

An autoimmune disease is..
- A.
The loss of immunity
- B.
The loss of self tolerance
- C.
The loss of an antigen
- D.
The loss of lymph
- E.
The loss of blood
Correct Answer
B. The loss of self toleranceExplanation
An autoimmune disease refers to a condition where the immune system mistakenly attacks healthy cells and tissues in the body. This occurs due to the loss of self-tolerance, which means that the immune system fails to recognize the body's own cells as "self" and instead targets them as if they were foreign invaders. This loss of self-tolerance leads to the immune system attacking and damaging various organs and tissues, resulting in autoimmune diseases.Rate this question:

Imagine that you are a pathogen in the human body. Suddenly, a large cell approaches you. The cell “reads” the antigens on your cell membrane, then it clamps on to you and prevents you from reproducing. In a few hours, you die. What kind of cell just killed you?
- A.
Macrophage
- B.
T-cell
- C.
Red blood cell
- D.
B-cell
Correct Answer
B. T-cellExplanation
A T-cell just killed the pathogen. T-cells are a type of white blood cell that play a crucial role in the immune response. They are responsible for recognizing foreign antigens on the surface of pathogens and activating the immune system to destroy them. In this scenario, the T-cell recognized the antigens on the pathogen's cell membrane, clamped onto it, and prevented it from reproducing. As a result, the pathogen was unable to survive and died within a few hours.Rate this question:

Aids is...
- A.
An opportunistic disease
- B.
The cause of HIV
- C.
The last stage in HIV infection
- D.
The source of the HIV infection
Correct Answer
C. The last stage in HIV infectionExplanation
AIDS is the last stage in HIV infection. HIV is a virus that attacks the immune system, and if left untreated, it can progress to AIDS. AIDS stands for Acquired Immunodeficiency Syndrome, and it is characterized by a severely weakened immune system, making individuals more susceptible to opportunistic infections and diseases. Therefore, AIDS is not the cause of HIV, but rather the final and most severe stage of the HIV infection.Rate this question:

The HIV virus can be killed by which item?
- A.
The immune system
- B.
Opportunistic diseases
- C.
Detergents
- D.
All of the above
Correct Answer
C. DetergentsExplanation
Detergents can kill the HIV virus because they have the ability to break down the protective envelope surrounding the virus. This envelope is essential for the virus to enter and infect human cells. Detergents disrupt the lipid membrane of the envelope, rendering the virus inactive and unable to cause infection.Rate this question:

As the body ages, the T-cells and B-cells become less responsive to ___
- A.
Antigens
- B.
Self tolerance
- C.
Antibodies
- D.
Immunity
Correct Answer
A. AntigensExplanation
As the body ages, the T-cells and B-cells, which are key components of the immune system, become less responsive to antigens. Antigens are substances that can trigger an immune response, such as viruses or bacteria. This decreased responsiveness can lead to a weakened immune system and reduced ability to fight off infections and diseases.Rate this question:
