What is the primary characteristic of innate immunity?
It is a specific, targeted response.
It involves antibodies and memory cells.
It is the body's immediate, non-specific first line of defense.
It only involves T cells.
Which of the following is a component of adaptive immunity?
Skin
Mucus
Antibodies
Inflammation
What type of immunity develops a specific, targeted response against a pathogen?
Innate immunity
Adaptive immunity
Non-specific immunity
General immunity
What is a characteristic of the innate immune response?
It targets specific pathogens.
It is a delayed response.
It is non-specific and immediate.
It requires prior exposure to pathogens.
Which of the following is a physical barrier in innate immunity?
Enzymes
Stomach acid
Skin
Antibodies
What is a sign that your body is raising the temperature to fight back against germs?
Coughing
Fever
Sneezing
Headache
What basic hygiene measure helps disrupt the spread of germs?
Wearing gloves
Handwashing
Using hand sanitizer
Wearing a mask
What are phagocytes?
Red blood cells that carry oxygen
White blood cells that engulf and destroy pathogens
Cells that produce antibodies
Cells that form blood clots
Which of the following is a characteristic of inflammation?
Decreased body temperature
Increased oxygen levels
Redness, heat, swelling, and pain
Production of antibodies
What type of cell is responsible for fighting infections in the body?
Red blood cell
White blood cell
Platelet
Nerve cell
What is phagocytosis?
The process of cell division
The process of engulfing and digesting foreign particles
The process of photosynthesis through plants
The process of protein synthesis in the bone marrow
Which type of phagocyte is long-lived and effective at engulfing foreign particles?
Neutrophils
Lymphocytes
Macrophages
Erythrocytes
What is the role of neutrophils in the immune response?
They produce antibodies
They are the first responders
They transport nutrients
They produce insulin
What is formed when a phagocyte engulfs a bacterium?
Lysosome
Phagosome
Ribosome
Chromosome
What is the function of lysosomes in phagocytes?
They store nutrients.
They produce antibodies.
They contain enzymes to break down bacteria.
They transport waste.
What happens during the digestion phase of phagocytosis?
The pathogen is broken down into proteins and other molecules.
The phagocyte engulfs the pathogen.
The phagocyte presents the antigen.
The pathogen interacts with phagocyte receptors.
What role does the Major Histocompatibility Complex (MHC) play in phagocytosis?
It helps the phagocyte engulf the pathogen.
It digests the pathogen.
It presents the antigen to the immune system.
It interacts with the pathogen receptors.
What is a characteristic of the adaptive immune response?
It provides immediate protection.
It targets and remembers specific pathogens.
It is non-specific and general.
It does not provide long-term protection.
Why is the adaptive immune response slower?
It is always active.
It takes time to develop specific defenses against new pathogens.
It does not recognize pathogens.
It is overwhelmed by pathogens.
What is another name for the adaptive immune system?
Innate immunity
Passive immunity
Acquired immunity
Natural immunity
How does the adaptive immune system respond to threats compared to the innate system?
It responds broadly to all threats
It activates in response to a specific threat
It does not respond to threats
It responds immediately to all threats
What advantage does the adaptive immune system have upon re-exposure to a pathogen?
It ignores the pathogen
It creates a slower response
It creates a memory for a faster, stronger response
It weakens the response
What are the two major types of lymphocytes?
Neutrophils and eosinophils
B-lymphocytes and T-lymphocytes
Monocytes and basophils
Red blood cells and platelets
What is the role of memory cells in lymphocytes?
They attack all cells indiscriminately
They remember encountered antigens for faster future responses
They produce antibodies continuously
They digest pathogens directly
How do lymphocytes differ from phagocytes in their approach to fighting pathogens?
Lymphocytes target specific antigens, while phagocytes engulf pathogens
Lymphocytes engulf pathogens, while phagocytes target specific antigens
Both target specific antigens
Both engulf pathogens
Where are B cells formed in the body?
Thymus
Bone marrow
Spleen
Lymph nodes
What process do B cells work in?
Cellular response
Humoral response
Inflammatory response
Nervous response
What happens to B cells when they meet an antigen in the lymphatic system?
They die
They divide
They mature
They shrink
What are antibodies?
Proteins produced by B cells that neutralize specific pathogens
Cells that attack and destroy pathogens directly
Hormones that regulate immune responses
Enzymes that digest foreign particles
What is the unique feature of each B cell's surface receptors?
They are identical to all other B cells.
They are specific to antigens and determined by the organism's DNA.
They are randomly generated without any specific pattern.
They are only present in mature B cells.
What are B cell receptors also known as?
Free-floating antibodies
Membrane-bound antibodies
Soluble proteins
Cytoplasmic enzymes
