Questions And Answers
1. Regarding the levels of biological organization: cell, tissue, organ, and organ
system, which of the following pairings is correct?
a. Organ: skin
b. Tissue: heart
c. Organ system: blood
d. Cell: integumentary - ANSWER-. A: Tissue consists of cells of a particular
type. The main four types are epithelial, connective, muscle, and nerve
cells. An organ is a functional entity made up of at least two different
tissue types, specialized for different functions within the organ. Including,
epithelial, connective, nerve, and muscle tissue, the skin constitutes an
organ, as does the heart. The name of the organ system to which skin
belongs is the integumentary system, which includes not only skin but also
accessories such as nails and hair. Connective tissue is the most diverse
type of tissue, including a range of tissue subtypes—the densest is bone,
and the loosest is blood.
2. . Which of the following glands is both endocrine AND exocrine?
a. Adrenal
b. Pituitary
c. Pancreas
d. Prostate - ANSWER-C: Exocrine glands are those glands that secrete
substances such as enzymes or mucous through ducts so that the
destination is not the blood. Such glands include skin glands and glands of
, the digestive and reproductive tracts. The prostate falls into this category,
as it secretes into ducts that contribute to seminal fluid. Endocrine glands,
on the other hand, secrete hormones through capillaries into the blood.
The pituitary and adrenal glands both fall into this category. Located in the
abdominal cavity, the pancreas has an exocrine function, secreting
digestive enzymes into the gastrointestinal tract. However, it is also an
endocrine gland, releasing glucagon and insulin into the blood.
3. 1000 mm (1 meter) equals:
i. 25.4 inches
ii. 37 inches
iii. 36.6 inches
iv. 39.3 inches - ANSWER-39.3 inches
4. 2.5 Kg =
i. 5.5 lbs
ii. 5.25 lbs
iii. 6.00 lbs
iv. 5.75 lbs - ANSWER-5.5 lbs
5. 240 CC equals:
i. 2.40 mL
ii. 240 mL
iii. 24.0 mL
iv. 2400 mL - ANSWER-240 ml
6. 3 waves with artifact on lead 2 and 3. What lead is bad? - ANSWER-LL
7. 32. If the SA node fails (the hearts natural pacemaker). What escape rhythm
takes over first?
i. Atria-ventricular rhythm
, ii. Atria-ventricular node rhythm
iii. Ventricular rhythm
iv. Coronary node rhythm - ANSWER-Atria-ventricular node rhythm
8. A blood pH of 7.4 is?
i. Acidosis
ii. Alkalosis
iii. Normal
iv. Base stabilized - ANSWER-Normal
9. A flow cytometer is providing a weak fluorescence intensity. This could be due to
which of the following problems?
a. Excess antibody has been trapped
b. Several populations of cells are present in the sample, instead of one
c. The primary antibody and the secondary antibody are not compatible
d. The sample is contaminated with bacteria - ANSWER-C: Flow cytometers
are used to count tiny particles, such as cells and chromosomes. The
particles are suspended in a stream of liquid and recognized by
fluorescent tags that are attached to the particles through antibodies. To
amplify the signal, two antibodies are used. The primary antibody
recognizes antigens on the particles themselves. In the case of cells, such
antigens are molecules displayed on the cell surface. The primary
antibody is made by, or using information from, the immune system of any
of several animals, including humans. While the area of the primary
antibody that binds the antigen on the cell is very specific to that antigen,
the opposite end of the antibody is common to other members of the
species from which the antibody was made. The fluorescent dye is
attached to secondary antibodies, which attach to the species-specific
antigens on the primary antibodies. The primary antibodies made from a
mouse, for instance, need to be labeled with secondary antibodies that are
"antimouse." If the labeled secondary antibody in this case were
