Diabetes Insipidus Antidiuretic hormone is not secreted
i,- i,-i,- i,- i,- i,- i,- i,- i,-



adequately, or the kidney is resistant to its effect. The *serum
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



sodium is often elevated* due to excess free water losses.
i,- i,- i,- i,- i,- i,- i,- i,- i,-

Cardiac Valve Disease Process
i,- In heart valve disease, one or i,- i,- i,-i,- i,- i,- i,- i,- i,- i,- i,-



more of the valves in your heart doesn't work properly.
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



Regurgitation (or leakage of the valve). When the valve(s) do not i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



close completely, it causes blood to flow backward through the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



valve. This reduces forward blood flow and can lead to volume
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



overload in the heart. i,- i,- i,-




Stenosis (or narrowing of the valve). When the valve(s) opening
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



becomes narrowed, it limits the flow of blood out of the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-

,ventricles or atria. The heart is forced to pump blood with
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



increased force to move blood through the narrowed or stiff
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



(stenotic) valve(s). i,-

i,- i,-i,- i,- i,- i,- i,- i,- i,- i,- i,-



recessive allele for a dysfunctional enzyme leads to the
i,- i,- i,- i,- i,- i,- i,- i,- i,-



accumulation of certain lipids in the brain. i,- i,- i,- i,- i,- i,- i,-




Seizures, blindness, and degeneration of motor and mental
i,- i,- i,- i,- i,- i,- i,- i,-

that cause viral hemorrhagic fevers live in a variety of animal and
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



insect hosts. i,- i,-




Most commonly, the hosts include mosquitoes, ticks, rodents, or
i,- i,- i,- i,- i,- i,- i,- i,- i,-



bats. Some viral hemorrhagic fevers can also be spread from
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



person to person. i,- i,-

Acid Base Balance - lung and kidney compensation
i,- i,- The i,- i,- i,- i,- i,- i,-i,- i,- i,-



kidneys have two main ways to maintain acid-base balance - their
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-

, cells reabsorb bicarbonate HCO3− from the urine back to the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



blood and they secrete hydrogen H+ ions into the urine.
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-

i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



copy of the altered gene in each cell is sufficient to cause the
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



disorder. i,-




At least 25 percent of Marfan syndrome cases result from a new
i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,- i,-



mutation in the FBN1 gene i,- i,- i,- i,-
