Anatomy Chapter 19
What are common sources of vitamin K?
- organ meats - whole grains - green vegetables - intestinal bacteria
People with type AB blood are considered the "universal recipient" for transfusions because
their blood lacks A or B agglutinins.
When a person who lives at sea level vacations in the Rocky Mountains, you would expect
- a rise in hematocrit - a drop in oxygen levels - the release of erythropoietin
The function of red blood cells is to
- carry carbon dioxide from the cells to the lungs - carry oxygen from the lungs to the body's cells
A digestive disorder that impairs a person's ability to absorb vitamin K will result in
- low levels of thromboplastin - low levels of prothrombin - low levels of Factor - prolonged bleeding
A person with Type A blood has
-Antigen A on the RBCs -anti-B agglutinins in the plasma
The yellow color that is visible in the eyes and skin in jaundice results from
-extensive breakdown of RBCs - destruction of hemoglobin - excessive amounts of bilirubin in the plasma - the yellow pigment, carotene
Which of the following is a function of the blood?
-transport of nutrients and wastes - transport of body heat - transport of gases - defense against toxins and pathogens
The average lifespan of a red blood cell is
4 months
Which of these is not one of the formed elements of blood?
antibodies
The process of red blood cell production is called
erythropoiesis
A hematocrit provides information on
formed elements abundance
Each hemoglobin molecule contains
four iron atoms
Plasma is closest in composition to
interstitial fluid
During a bacterial infection you would expect to see increased numbers of
neutrophils
Which of these descriptions best matches the term eosinophils?
often elevated in allergic individuals
A person's blood type is determined largely by the
presence of specific glycoproteins on the cell membrane
Which of these descriptions best matches the term T lymphocytes?
produce antibodies in response to antigen
Bill wants to determine his blood type, so he takes a few drops of blood from a puncture wound in his finger and mixes it with various antisera. His blood cells agglutinate when mixed with the anti-A sera but not with the anti-B or anti-D sera. This means
Bill's plasma contains B agglutinins.
The combination of plasma and formed elements is called
whole blood
