| Question | Answer |
|---|---|
| What is personal health literacy? | how much a person understands their health issues |
| What is organizational health literacy? | how easily it is for people to understand their health information from an organization |
| The ultimate goal is for people to: | use health information rather than just understand it, and to make "well-informed" decisions rather than "appropriate" ones |
| People with low health literacy: | more likely to visit a hospital, have more hospital stays, less likely to follow treatment plans, have higher mortality rates |
| What can be done to improve health literacy: | easy-to-navigate patient portals, use plain language, bilingual staff, clear directions for medicine |
| Hospitals: | high cost, for people who need extreme assistance, ICU, trauma center, ER, staying overnight in the hospital |
| Ambulatory/outpatient services: | urgent care enter, dental offices , surgical centers, school nurses |
| Long-term care facilities: | for people who don't need hospitalization, but can't live at home, nursing home, assisted living |
| Home health care services: | provide care to patients in their own homes, medical equipment that can be used at home, less hospital stays |
| Hospice: | palliative care and support for dying patients and their families, medical, emotional and spiritual support, make patients comfortable and pain-free |
| Government health services: | CDC, OSHA, vaccines, collect data, screen for diseases |
| What is lymph? | Clear-to-white watery fluid containing electrolytes and proteins, and white blood cells |
| What direction does lymph flow? | in one direction; filtered by lymph nodes |
| What does the lymphatic system depend on? | the pumping motion of the heart |
| The three functions of lymph: | absorbs fats and fat-soluble vitamins through the lacteals of the small intestine, remove waste products from the tissues and supports the immune system in destroying invading pathogens, returns filtered lymph to the veins at the base of the neck |
| Natural killer cells (NK cells) | play a role in killing cancer cells and cells infected by viruses |
| B cells (B lymphocytes) | specialized lymphocytes that produce antibodies |
| T cells (T lymphocytes) | T comes from thymus, cell mediated immunity |
| Cytokines | group of proteins, act as intracellular signals to begin the immune response |
| Interferons | activate the immune system, fight viruses, signals other cells, |
| Interleukins | direct B and T cells to divide and proliferate |
| Natural immunity | being born with immunity |
| Acquired immunity | obtained by having had a disease |
| Vaccination | a shot that provides immunity to a disease |
| What is a pathogen? | microorganism that causes disease in humans |
| What are bacteria? | one-celled microscopic organisms, most aren't harmful to humans |
| What are antibiotic-resistant bacteria? | bacteria that have built up and immunity to typical treatement |
| What is a fungus? | a simple parasitic organism |
| What are yeast? | a type of fungus, single-celled |
| Toxoplasmosis | caused by a parasite, transmitted by animal feces |
| What is a herpesvirus | a group of viruses that cause a variety of diseases in humans |

| What is a bacteriostatic agent | slows or stops the growth of bacteria |
| What is a bactericide | causes death of the bacteria |
| What does the urinary system do? | maintains water, electrolytes, and acid balance, filtering blood to remove urea, creatinine, uric acid, and other waste, converting waste products and excess fluids to urine in the kidneys |
| What makes up the urinary system? | two kidneys, two ureters, one bladder, and one urethra |
| What are the adrenal glands? | part of the endocrine system, located on top of the kidneys |
| What is the genitourinary tract? | reference to two body systems, urinary tract and reproductive organs |
| Renal cortex: | outer region of the kidney, contains nephrons |
| Medulla: | inner 'meaty' region, contains most urine-collecting tubules |
| Nephrons: | microscopic function units of kidneys, produce urine |
| Urinary bladder: | oval, hollow, muscular organ, acts as a reservoir for urine before it is excreted |
| Urethra: | tube from the bladder to exterior of body, has two urinary sphincters |
| Prostate gland: | part of the male reproductive system, surrounds the urethra |
