Which term best describes the function of blood when considering the presence of leukocytes and antibodies? Protection Blood helps regulate the pH and the temperature of the body. True Oxygen poor blood is _________ in color. dark red The viscosity of blood is ________ proportional to the number of erythrocytes and _______ proportional to the amount of fluid Directly, indirectly Blood plasma is slightly _______; if pH drifts out of the normal range, dire consequences can result from alterations in the structure of _______ basic, proteins The "buffy" coat of the middle layer of a centrifuged blood sample is composed of: platelets and leukocytes The clinical definition of the hematocrit refers to the percentage of: erythrocytes in the blood A malnourished person might have abnormally low levels of plasma proteins. As a result, colloid osmotic pressure: decreases, and there is fluid retention in the interstitial space One of the functions of blood is to regulate fluid levels in the body. If too much fluid escapes from the bloodstream and enters the tissues, blood pressure will decrease An individual's hematocrit would vary with age, sex , altitude Sodium, calcium, and bicarbonate are all described as plasma: electrolytes The reason it is more appropriate to call an erythrocyte a "formed element" rather than a "cell" is that erythrocytes: lack of nucleus and organelles The hemoglobin found in erythrocytes is able to chemically attach to: both oxygen and carbon dioxide Extensions from megakaryocytes that extend through blood vessel walls in red marrow are sliced off from the cells by the force of blood flow. These extensions are: proplatelets n hemopoiesis, granulocytes such as neutrophils are formed from the _________ line. myeloid The life span of an erythrocyte is about _________ days 120 Old erythrocytes are phagocytized in the: liver and spleen Which are characteristics of type O blood? a: Has anti-A antibodies b: Has anti-B antibodies c: Has surface antigen O on its erythrocytes d: Has surface antigen A on its erythrocytes e: Has neither surface antigen A nor B on its erythrocytes a, b, e Which are characteristic of type Rh negative blood? a: Always has Rh (anti-D) antibodies b: Only under certain conditions will Rh (anti-D) antibodies be present c: Always has Rh (D) antigen d: Only under certain conditions will the Rh (D) antigen be present e: Is inherited independent of the ABO group b, e The agglutinogens (or antigens) that determine the ABO and Rh blood types are: found on the surgace of erythrocytes

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
