verified solutions
Describe how your body responds to an infection. - ANSWER- T cells produce
cytokines, which stimulate B cells. B cells produce antibodies.
Identify role of DNA changes in congenital abnormalities. - ANSWER- Mutations
in genes or chromosomal abnormalities
How does development disrupts congenital abnormalities? - ANSWER-
Alterations of DNA
Describes factors that disrupt homeostasis and how disruptions affect wellbeing.
- ANSWER- (ex) Fluid and electrolyte shifts can cause n/v or dysrhythmias.
Explain RAAS - ANSWER- Renin-angiotensin-aldosterone system
1. Reduce blood flow causes kidneys to release renin
> produce angiotensin I > converts angiotensin I to angiotensin II >
vasoconstriction > release aldosterone > kidneys conserve sodium and water >
Result less water lost in urine and blood pressure maintained.
DKA - ANSWER- increased anion gap, decreased HCO3
How do kidneys compensate for alkalosis - ANSWER- retain H and excrete HCO3
,Untreated acidosis leads to an increase in which electrolyte? - ANSWER-
Potassium
West Nile Virus - ANSWER- Transmitted through the bite of an infected
mosquito. Severe signs and symptoms; high fever, headache and stiff neck
Lyme disease - ANSWER- Tick-borne disease caused by the spirochete Borrelia

redness, blisters, scabs, and itching
decubitus ulcer - ANSWER- sore caused by lying down for long periods of time
Fungal infections - ANSWER- superficial, localized skin conditions or deep tissue
infections caused by exposure to spores
may or may not be transmitted
benign neoplasm - ANSWER- noncancerous growths, stationary, distinct borders
malignant neoplasm - ANSWER- uncontrolled new tissue growth, irregular
borders, spreads
Osteoporosis - ANSWER- The loss of bone mass often due to age, causing the
bones to become porous, brittle, and easily fractured.
osteomalacia - ANSWER- disease marked by softening of the bone caused by
calcium and vitamin D deficiency
myoglobin - ANSWER- red pigment that stores oxygen in muscle cells
Bursa - ANSWER- fluid-filled sac that allows for easy movement of one part of a
joint over another
Rickets - ANSWER- a vitamin D deficiency in children, resulting in soft bones
Degenerative disk disease - ANSWER- A condition in which an intervertebral
disk loses its normal structural integrity as a result of wear and tear, acute or
repeated injuries or aging
Paget disease - ANSWER- Chronic inflammation of bones, resulting in thickening
and softening of bones, that can occur in any bone but most commonly affects
the long bones of the legs, the lower spine, the pelvis, and the skull
communiuted fracture - ANSWER- splintered into many pieces
