decreased osmotic uptake
the following is true of mitosis:
it results in 2 cells genetically identical to the orignal.
Normal human cells (except sperm and eggs) have a total o f how many chromosomes?
Liver failure can cause edema by:
decreasing protein levels in the blood.
Hypertension can cause edema by:
Increasing capillary filtration
Basal cell carcinoma is:
the force that draws water through a semipermeable membrane from a solution of lower solute concentration to a solution of higher concentration
A healty cell..
has more sodium outside than inside
what is considered normal serum pH?
Inflammation can cause edema by:
increasing capillary permeability to proteins
a tumore that is encapsulated, slowly expanding mass made up of relatively normal cells might be a
When the osmotic pressure(solute concentration) of the blood is elevated above normal, water would shift from the:
interstiial compartment (ECF:extracellular fluid) into the blood
Filariasis can cause edema by:
blocking lymp vessels
the structure of a virus includes:
a protein coat and DNA or RNA
Leiomyoma is:
benigh: from smooth muscle tissue
charactristic of HIV+
antibodies in blood indicate presence of virus and possible transmission to others
Liver failure can cause edema by:
decreasing proteins out of the body
AIDS is a syndrome defined specifically by T-cell count and infections, Being HIV+ indicates the presence of antibodies to the virus, One can be HIV+ and NOT have AIDS:but one cannot have AIDS w/o being HIV+
true regarding HIV/AIDS

Antidiuretic Hormone and Aldosterone control amount of water, Na+ and K+ reabsorption
Hormonal Control
How can kidney failure cause edema?
excreting proteins out of the body

step throat
athlete's foot
oral "thrus" infection
what happens to serum pH when many excess hydrogen ions accumulate in the blood?
serum pH decreases
what is essential in order tomaintain serum pH within normal range.
the normal ratio of carbonic acid to bicarbonate must be 1:20 (bicarbonate to carbonic acid 20:1)
what is the correct effect on the body of abnormally slow respirations (carbonic acid)?
increased carbonic acid
what would cause metabolic acidosis
prolonged diarrea

adrenal cortex
During the stress response, cortisole assists in:
increasing blood glucose levels
Norepinephrine and epinephrine
are secreted as part of the sympathetic nervouse sys response to stress
Each spinal nerve conducts impulses from a specific area of the skin called

protrhombin activator
in normal homeostatic balance, which substances should be dominant in their effects?
anti-clotting factors
for a person to have sickle cell anemia a person must
inherit one sickled hemogolobin gene from each parent
Sickle trait means that a person has
1 hbs gene and one normal hemoglobin gene

why does ventricular fibrillation result in cardiac arrest
insufficient blood is supplied to the myocardium
signs of right sided heart failure
edematous feet and legs with hepatomegaly
where will failure of the left ventricle cause increased pressure
