Human Anatomy & Physiology: All About Blood 2

Red blood cells are also known as what?

The shape of red blood cells plays a very important role in their function. The centers are _ than the edges which makes them look like _______.

The ______ the surface area of a red blood cell, the faster gasses can diffuse.

_________ allows red blood cells to form stacks like dinner plates which allows them to pass through a vessel not much larger than the diameter of the red blood cell.

Red blood cells are quite elastic and flexible which enables them to bend and flex when entering small capillaries. This is known as what?

The average size of a red blood cell is about _____ micrometers in diameter.

Each red blood cell is about ____ hemoglobin by volume.

The normal values of hemoglobin in an adult female are ______ gm per 100 ml of whole blood.

The normal values of hemoglobin in an adult male are _____ gm per 100 ml of whole blood.

Red blood cell counts equal the number of cells per cubic millimeter of bloods the normal values (average) for an adult female are ________ million cells per cubic millimeter.

Hemoglobin is responsible for the red blood cell's ability to transport and _.

_______ is a compound formed when oxygen combines with hemoglobin which causes the blood to be bright red in color.

_______ is the iron-containing pigment of red blood cells responsible for the color of blood.

________ refers to hemoglobin that has released its oxygen which gives the blood a bluish appearance.

__________ is the result of an increase in the concentration of deoxyhemoglobin which causes a bluish discoloration of the skin and mucous membranes.

A mature red blood cell lacks a ________.

Mature red blood cells depend only on _______ to meet their energy needs.

A single round trip from the heart, through the peripheral tissues and back to the heart usually takes less than a minute. With all this wear and tear and no repair mechanisms the average circulating life span of a red blood cell is about ______ days.

Macrophages in the and the _ phagocytize and destroy damaged red blood cells.

What two subunits are hemoglobin molecules that have been liberated from destroyed red blood cells break down into?

Heme is further broken down into _ and __.

When heme breaks down, the iron is released into the blood and is bound with a plasma protein called _________. It is then transferred to the bone marrow where it is recycled over and over again to produce more hemoglobin.

About 80% of the iron released into the blood is stored in liver cells in the form of an iron-protein complex called ________. This occurs if the iron is not needed immediately for synthesis of new hemoglobin.

__ is a greenish pigment which will eventually be converted to _ which is an orange pigment. Both of these pigments are excreted from the liver as ________.

Globin is the portion which is then degraded to __ to be reused or catabolized.

Red blood cell production is better known as_________.

During infancy, red blood cell production takes place in the entire medullary space, but in gradually decreases in the shaft of the long bones. After what age do fat cells begin to appear in the long bones.

As an adult, red bone marrow is found in all of the following places except which one?

________ are the stem cells within the red bone marrow which give rise to several types of commited stem cells.

________ are one type of commited stem cell. They are relatively large with loose, lacy chromatin. They have clearly visible nucleoli and basophilic cytoplasm. They undergo a number of mitotic divisions to eventually give rise to the next type of cell.

_________ undergo mitosis and give rise to many daughter cells which insures a large population of these cells. They contain sufficient hemoglobin to exhibit pink staining within the cytoplasm. They also contain nuclei and all of the polyribosomes to synthesize large amounts of hemoglobin.

________ appear pink in color, have nuclei that are quite small and no basophilic cytoplasm is evident. After about four days, they put forth a series of cytoplasmic protrusions which cause their nuclei to be expelled with a small amount of cytoplasm.

Cells that remain after the nuclei have been ejected are known as _____________. They contain 80% of the hemoglobin of a mature red blood cell. Although these cells lack a nucleus, hemoglobin synthesis continues due to the presence of polyribosomes.

Low oxygen levels may be caused by what 3 things?

The availability of what two B-complex vitamins vitamins affect the production of red blood cells?

B-complex vitamins are needed by red blood cells for _____________.

___________ is needed for hemoglobin synthesis

Of the _mg of iron present in erythrocytes that are destroyed each day, only mg is excreted in the urine and must be replaced.
