BIOD 151 Final Exam 2025 (Portage Learning) | Human
Anatomy and Physiology | Featuring Topics such as
Cardiovascular, Respiratory, Digestive, Nervous,
Musculoskeletal, Urinary, and Endocrine
Which one of the following is not true of active transport? ---------CORRECT
ANSWER-----------------Active transport moves particles with the concentration
gradient
List the three organelles, in order, involved in the synthesis, transport and
shipping of proteins. ---------CORRECT ANSWER-----------------ribosomes, rough ER,
Golgi complex
The purpose of cellular respiration is to produce ADP. (T or F) ---------CORRECT
ANSWER-----------------a. False- (ATP is produced, not ADP)
Peripheral proteins are found on the outer surface of a cell membrane. (T or F) ----
-----CORRECT ANSWER-----------------True
Exocytosis is the process that occurs to bring biomacromolecules inside the cell. (T
or F) ---------CORRECT ANSWER-----------------False- (This process is called
endocytosis)
,Receptor-mediated endocytosis uses a signaling molecule from another cell,
binding to the cell membrane to bring about changes within the cell proteins. (T
or F) ---------CORRECT ANSWER-----------------True
Endocytosis is a passive process. It does not require cellular energy expenditure.
(T or F) ---------CORRECT ANSWER-----------------False - endocytosis is an active
process and requires cellular energy
Explain what happens to the soft palate during swallowing. Why? ---------CORRECT
ANSWER-----------------The upward movement of the soft palate prevents food or
liquid from entering the nasal passages during swallowing.
Explain at least two differences between Type I and Type II alveolar cells. ---------
CORRECT ANSWER-----------------a. Type I form the very thin simple squamous
epithelium of the alveoli in junction with capillaries. Make up roughly 95% of
alveolar epithelial cells.
b. Type II produce and secrete pulmonary surfactant which is needed throughout
the alveolar surface to keep the alveoli open.
In addition, Type II cells can divide to replace damaged Type I cells. Make up
roughly 5% of alveolar epithelial cells.
,True/False: Positive pressure is used to move air into the lungs. ---------CORRECT
ANSWER-----------------false (negative pressure)
True/False: During inhalation the diaphragm contracts to pull the lungs open. ------
---CORRECT ANSWER-----------------True
True/False: During inhalation the rib cage is lowered, pulling the lungs open. -------
--CORRECT ANSWER-----------------False - rib cage is lifted upward during inhalation
True/False: As the thoracic cavity expands and lung volume increases, the density
of the gases filling the lungs decreases. ---------CORRECT ANSWER-----------------
True
True/False: As the rib cage expands during inhalation, air will naturally flow into
the lungs. ---------CORRECT ANSWER-----------------True (air will naturally flow into
the lungs because of the negative pressure inside the lungs)
According to Charles's Law gas volume is: ---------CORRECT ANSWER-----------------
Directly proportional to its temperature
, Which one of the following tracheal cartilages are paired? ---------CORRECT
ANSWER-----------------Arytenoid
Which cells are most abundant within the alveoli? ---------CORRECT ANSWER--------
---------macrophages
Which one of the following is not true of the respiratory physiology? ---------
CORRECT ANSWER-----------------Tidal volume is the maximum amount of air able
to be inhaled beyond normal inhalation
Which one of the following is true of the respiratory physiology calculations? ------
---CORRECT ANSWER-----------------Functional Residual Capacity (FRC) = RV+ERV
True/False:
Typical respiratory epithelium contains cells where only some of the
pseudostratified columnar cells touch the basement membrane. ---------CORRECT
ANSWER-----------------False -all pseudostratified cells touch the basement
membrane.
What is the study of the structure of the human body? ---------CORRECT ANSWER--
