What is NOT a contributor to the increased incidence of asthma in the human population? |
All Of The Above Have Been Proposed: -Increased Vaccines -Better Hygiene -Increased Air Pollution -Increased Antibiotic Use in Infancy. |
|
The integumentary system (physical barriers) uses what barriers? |
-Tears -Earwax -Acidic Urine -Cilia in the respiratory tract |
|
One difference between the innate and adaptive immune system is that when you first encounter a new foreign invader, that latter is slower than the former. Why? |
The innate system has all its components already present. The adaptive system must first be stimulated into action, cell division must "ramp up" |
|
Viruses are able to infect... |
Humans Plants Bacteria Birds |
|
How does injecting a person with killed-bacteria vaccine protect that individual from a disease? |
They stimulate the formation of memory cells primed to recognize a particular pathogen. |
|
Why don't people develop immunity to the common cold? |
There are at least 200 different viruses that can cause the common cold, and they change over time. Even if your body adapts, a new one can come. |
|
A person suffers from a chronic infection and develops an abscess that produces pus. Pus consist primarily of dead... |
Neutrophils |
|
Why doesn't passive immunity last very long? |
Passive Immunity: Memory cells against a pathogen are not produced when antibodies are transferred to a person's body. Passive Immunity = Putting Antibodies in you from another person |
|
The name for the condition where an individual's immune system responds inappropriately to "self" antigens is called: |
Autoimmunity |
|
The role of the stomach with regards to immunity is: |
To destroy microbes with strongly acidic gastric juices. |
|
The three ways in which our bodies prevent and fight infection include non-specific immunity, specific immunity, and: |
Physical Barriers |
|
Which of the following combinations differentiates between the targets of the humoral versus the cell-mediated immune responses? (difference b/t B + T cells!) |
Humoral: Pathogens in blood + lymph Cell Mediated: Pathogens and toxins inside body cells |
|
The role of B cells in the specific immune system is to: |
Make antibodies that bind to antigens on the pathogen. |
|
|
The major difference between T cells and B cells is that... |
- T cells mature in the thymus, B cells in the bone marrow -T cells don't interact with the innate immune system, B cells do. -T cells bind to foreign antigens, B cells produce proteins that bind to to the antigens |
|
|
The "secondary" immune response refers to: |
None of the above. Definition: Shorter lag time. |
