a buffer has to have..

A

a weak acid or a weak base. it has to have a conjugate (different in one proton) salt.

80
Q

all buffers do not maintain a ph of..

A
  1. You can change the pH of the buffer solution by changing the ratio of acid to salt, or by selecting a different acid and one of its salts.
81
Q

blood plasma is..

A

a weak buffer. Remember that it is designed to buffer around pH 7.4 and therefore its capabilities are limited to weak acids or alkalis

82
Q

Biuret reagent is a…(color)

A

heated at 37 degrees celcius, perfect temp for amalyse to react on starch and turn it to maltose

86
Q

yellow trypsin test (bap)

A

(incubated at 37 degrees C) strong digestion of bapna of trypsin

87
Q

A purple color indicates the presence of protein, specifically albumin in this experiment. Why is that considered a negative result? (israel)

A

The test gives positive result to any compound containing two carbonyl groups attached to a nitrogen or carbon atom.

Q

Biuret is a color indicator that turns pink in acidic conditions. The pink color in tube 4P indicates a positive result. (pep)

90
Q

without emulsification in fat test at 37 degees..

A

digestion of cream was difficult.

91
Q

heart murmur

A

Abnormal heart sounds are usually associated with cardiac disease and are called murmurs. Sometimes a non-pathological murmur (called a functional murmur) can be heard, probably due to relatively thin heart walls that vibrate with rushing blood. Functional murmurs are more common in very young or elderly individuals.
Pathological murmurs are heard due to turbulent blood flow that causes vibrations in the heart.

92
Q

stenotic valve

A

valve is a stiff, narrowed valve that does not open completely - screetching or whistling sound

93
Q

insufficient or incompetent (also known as prolapsed) valve (backwards gurgle)

A

does not close completely, and backward flow of blood creates a swishing or gurgling sound. This is sometimes referred to as regurgitation

94
Q

systolic murmur (sister first)

A

A murmur occurring between the first and second heart sounds (lub-murmur-dup).

95
Q

diastolic murmur

A

a murmur occurs between the second and first heart sounds (lub-dup-murmur).

96
Q

RBCs

A

Red blood cells carry oxygen from our lungs to the rest of our bodies.

97
Q

platelets

A

They are important in the clotting process

98
Q

A

They are active phagocytes and fight bacterial invasions (important in inflammatory response) as well as cleaning up debris

99
Q
