Cards

Term
Neutrophil
Definition
First responders to bacterial infection. Account for 50-70% of white blood cells.
Term
Lymphocyte
Definition
Responsible for specific immunity to particular pathogens and toxins. Account for 25-35% of white blood cells
Term
Monocytes
Definition
type of agranular white blood cell that functions as a phagocyte and an antigen-presenting cell.
Term
Eosinophils
Definition
White blood cells containing cytoplasmic granules that stain with acidic dye.
Term
Basophils
Definition
White blood cell with granular cytoplasm; able to be stained with a basic dye
Term
T-cells
Definition
mature in the thymus
Term
Cytotoxic t-cells
Definition
T-cells that attack and kill antigen-bearing cells.
Term
Helper T-cells
Definition
T-cell that secretes cytokines that stimulate all types of immune system cells.
Term
Memory T-cells
Definition
differentiates during an initial infection and responds rapidly during subsequent exposure to the same antigen.
Term
Suppressor T-Cells
Definition
Reduces or suppresses the immune response of B-cells or other T-cells to an antigen.
Term
B-cells
Definition
Mature in the bone marrow; gives rise to antibody producing plasma cells when a specific antigen stimulates it.
Term
Plasma B cells
Definition
Specialized to mass produce antibodies
Term
Memory B-cells
Definition
Ready to produce antibodies in the future.
Term
The Antibiotic Sensitivity Test (Kirby Baur Test)
Definition
A test in which someone can look to see which antibiotic would be the most effective in killing the bacteria. They look for places on the plate where the bacteria did not grow, this is known as the Zone of Inhibition or Zone of Death. The bacteria is not able to grow near the appropriate antibiotic.
Term
When looking at a cloudy urine samplw with orange tinge in the color what test should be ordered to diagnose the problem?
Definition
Urinalysis
Term
Why do women suffer more urinary tract infections than men?
Definition
The uterus is closer to the anus and is shorter making it easier to reach the bladder. It is also closer to the vaginal walls.
Term
What is Honeymoon Cystitis?
Definition
the name for a urinary or bladder infection
Term
What is the difference between cystitis and pyelonephritis?
Definition
Pyelonephritis affects the kidney
Term
What is the best treatment for a Kidney Infection?
Definition
Antibiotics
Term
When a teacher deals with a student with pink eye what is the first thing she should do before returning to class?
Definition
Wash her hands
Term
What is the most likely diagnosis of a student with a crusty teary eye, yellow discharge,having difficulty opening, and is complaining about the pain?
Definition
conjunctivitis (pink eye)
Term
Are the symptoms different if the Conjunctivitis is caused by a bacterial infection or a viral infection?
Definition
yes. Differences include: more tears, watery discharge for viral; More yellow dischare and eyes stuck together for bacterial.
Term
What is the treatment for both bacterial and viral infections?
Definition
Eyedrops that help lubricate the eye and reduce inflammation.
Term
A male student is experiencing painful urination and pus discharge dripping from his penis... How can a Sexually Transmitted Infection be confirmed?
Definition
By getting tested. Tests include physical examinations, microscopic examination of cells, blood tests, and urine tests.
Term
Which White Blood Cells would be high in a patient that has a bacterial infection?
Definition
Neutrophils
Term
Benign Tumor
Definition
Surrounded by connective tissue capsule and does not usually spread
Term
Malignant Tumor
Definition
spreads from site of origin to other parts of the body
Term
Metastasis
Definition
the spread of cancer from the site of origin to other parts of the body
Term
Carcinoma
Definition
Cancer cells that cover internal and external body surfaces (Lung, breast, colon, bladder/prostate)
Term
Leukemia
Definition
cancer of the blood cells
Term
Lymphoma
Definition
cancer of the lymph nodes and tissues
Term
Sarcoma
Definition
cancer cells in the supportive tissues (bones and muscles)
Term
Mutation
Definition
changes the DNA sequence
Term
Proto Oncogenes
Definition
can form cancer; becomes an oncogene when cancer is present; creates codes for proteins that promote the cell cycle and prevent apoptosis.
Term
Oncogenes
Definition
cancer causing gene
Term
Tumor suppressor genes
Definition
stop tumors/cancer from developing
Term
Apoptosis
Definition
Programmed cell death
Term
Differences between Cancer cells and normal cells
Definition
Normal/Cancer
1.controlled growth/uncontrolled growth
2. Contact inhibition(stop growing after contact)/NO contact inhibition
3. One organized layer/Disorganized and multi-layered
4. Differentiated Cells/Non differentiated cells
5. Normal nuclei/abnormal nuclei
Term
How does cancer spread?
Definition
1. Normal cells secrete angiogene inhibitors all the time (yellow)
2. Cancer cells secrete blood vessel inhibitor (blue)
3. Primary tumor makes small amount of inhibitor
4. Metastasis pull in vessels and can grow
Term
Angiogenesis
Definition
the recruitment of blood vessels from the network of neighboring vessels.
Term
What are the causes of cancer?
Definition
Hereditary, Organic chemicals, radiation, viruses, oncogenes.
