55; 45
The production of the formed elements of the blood is called
hematopoiesis
What is plasma?
The water, proteins, nutrients, wastes, hormones and gases in blood
Name all of the potential locations for hematopoiesis the embryo and fetus. Select all that
apply.
-Yolk sac
-Red bone marrow
-Spleen
-Lymph nodes
Cells and cell fragments (platelets) found in the plasma are also called
formed elements
After birth, hematopoiesis occurs in
red bone marrow
Which is not a formed element of blood?
plasma
Describe how blood helps maintain homeostasis. Select all that apply.
Limits spread of pathogens
Stabilization of body fluids
,Transport of carbon dioxide
Transport of nutrients
The process of blood cell production is called
hematopoiesis
In the fetus, hematopoiesis occurs in the yolk sac, lymph nodes, red bone marrow,
___________________________, and thymus.
liver, spleen
Identify the formed elements of the blood. Select all that apply.
Erythrocytes
Platelets
Leukocytes
All formed elements of blood are derived from a stem cell called a(n)
hemocytoblast
Regulation of pH and body temperature, transport and protection are all functions of the
circulatory system
Males have______ red blood cells than women.
more
In the embryo and fetus, hematopoiesis occurs in
several different tissues
Describe how the unique structure of the erythrocyte plays an important role in its
function.
-Shape and the anucleate structure give the cell more flexibility to pass easily through small
vessels.
-The biconcave shape has greater surface area to allow increased diffusion.
Name the stem cell for all formed elements.
, hemocytoblast
Red blood cells______ their nuclei during maturation.
lose
Blood's homeostatic functions include
-maintenance of body temperature
-protection against foreign substances
-clot formation
Which of the following would be an abnormal RBC count for a man?
4.1 million RBCs/microliter
The major component (protein) of red blood cells is
hemoglobin
How does the shape of the red blood cell influence the cell's function?
The biconcave shape increases the surface-area-to-volume ratio and facilitates gas exchange.
What is the main function of red blood cells?
Transport both oxygen and carbon dioxide
Mature red blood cells are unable to divide or undergo protein synthesis. What feature of
the cell accounts for this?
lack a nucleus and other organelles
Hemoglobin is a protein that consists of______ subunits.
4
Iron is critical for the synthesis of ____________, the oxygen-carrying protein in red blood
cells.
hemoglobin
