T/F Pt 2 Flashcards
An iron deficiency may result in decreased blood-clotting ability (abnormal bleeding).
T or F?
False
Hematopoiesis in adults normally takes place in the spleen, liver, and red bone marrow.
T or F?
False
Malnutrition is expected to have an impact on blood clotting.
T or F?
True
Each of the 3 formed elements of blood has its own stem cell.
T or F?
False
Lymphocytes are found only in lymph nodes
T or F?
False
Red blood cells normally survive in the blood stream for about 4 weeks.
T or F?
False
Macrophages are white blood cells that have left the blood stream and entered the tissue space.
T or F?
True
Given that red blood cells may contain 250,000 hemoglobin molecules, each red blood cell may carry a million O2 molecules at one time.
T or F?
True
There are a maximum 4 iron atoms found in each red blood cell.
T or F?
False
Red blood cells are produced in red bone marrow and white blood cells are produced in yellow bone marrow.
T or F?
False
The function of neutrophils is more similar to that of macrophages than lymphocytes.
T or F?
True
Most of hematopoiesis takes place in areas of spongy bone.
T or F?
True
Of the respiratory gases O2 and CO2, only CO2 can directly change the pH of body fluids.
T or F?
True
Surfactant adheres the visceral pleura to the parietal pleura.
T or F?
False
In order for gas exchange to occur normally in the lungs, inhaled air must reach alveoli.
T or F?
True
While hyperventilating (i.e. breathing faster than needed to support cellular respiration), oxygen levels in the blood will increase significantly, while carbon dioxide levels will remain the same. T or F?
False
Gas exchange is an example of passive transport.
T or F?
False
External respiration takes place in the tissue fluid outside cells.
T or F?
False
Oxygen and carbon dioxide are not the only gases we breathe in and out, but they are the only gases involved in cellular respiration.
T or F?
True
Ventilation of the lungs (i.e. air movement into and out of the lungs) is accomplished by voluntary muscle tissues.
T or F?
True
While the body is at rest, exhalation is a passive process.
T or F?
True
