What am I?
I am a normal part of aging and development. I help the body get rid of old or damaged cells.
What is apoptosis (programmed cell death)
What are the differences between autophagy and apoptosis?
Autophagy- Survival mechanism that allows cells to recycle some parts of the cell while destroying the damaged parts. (Name an example?)
Apoptosis: Programmed cellular death that gets rid of old or damaged cells.
Which type of immunity is specific? Which type of immunity is non-specific and reacts the same way regardless of the cause?
Adaptive Immunity is specific.
Innate immunity responds the same way each time.
True or false: I am born with adaptive immunity.
False- we are born with INNATE immunity; adaptive immunity results from being exposed to microorganisms and developing antibodies against them.
I am a combination of liquefactive and coagulative necrosis and can be found in pulmonary tuberculosis. What am I?
What is caseous necrosis?
What differences do we see with local inflammation and systemic inflammation?
Local: Heat, edema, erythema, pain, loss of function
Systemic: Fever, increased WBC count, and increases plasma protein synthesis.
Which cells are the first to arrive to the scene? Which cells are the last?
Mast cells are the first to arrive while monocytes show up like "did you still need help...?"
What is a biochemical barrier? Name three examples.
A biochemical barrier is chemical substance the body produces to keep pathogens from entering/growing.
Examples include: mucus, saliva, sweat, tears, earwax, etc.
I am characterized by heat, erythema, edema, pain, and loss of function. What am I?
Local inflammation
What is the difference between a hypertrophic scar and a keloid?
A hypertrophic scar is raised, but remains but its borders stay within the lines of the original wound.
A keloid is raised but grows beyond the original wound.
What can lead to delayed wound healing?
diabetes, infections, ischemia, poor nutrition, inadequate sleep, old age, etc.
Name the phases of wound healing.
1. Hemostasis (coagulation)
2. Inflammation
3. Proliferation and New Tissue Formation
4. Remodeling and Maturation
My numbers increase when there is a parasitic infection or allergy present. What am I?
What are eosinophils?
What is the difference between hypertrophy and hyperplasia?
Hypertrophy refers to an increase in SIZE of the cells.
Hyperplasia refers to an increase in NUMBER of cells.
True or False: Adaptive immunity protects against reinfection. Explain why or why not.
True- antibodies continue to circulate in case the same antigen returns.
Which system involves fibrinogen and fibrin?
The clotting system
I am the result of an unresolved acute illness. I contain granulomas and resistant microorganisms.
What is chronic inflammation?
Primary Intention vs. Secondary Intention
Primary Intention- Wound edges are brought back together. (Name examples)
Secondary Intention- Wound has to heal from the bottom up. (name examples
True or False: Because children can heal faster, this means that children have stronger and more developed immune systems than young adults.
False.
What does purulent pus look like? What is it a sign of?
Purulent pus may be thick, yellowish/green in color and is often a sign of infection!
