Exam 4: The Blood Flashcards
A fluid connective tissue consisting of blood cells and platelets.
Blood
Blood contains
Dissolved protein fibers in watery ground substance
Red blood cells transport what
Oxygen and carbon dioxide
White blood cell function
Fight off infections
Platelets and dissolved proteins help with
Clotting
Blood makes up what percent of body mass
8
How many liters of blood are produced each day in women and men?
Women= 4-5
Male=5-6
Blood has what components when separated by centrifuge?
Plasma, Buffy coat, and erythrocytes
Plasma makes up
55% of whole blood
What is in plasma
Water, proteins, and other solutes such as electrolytes and nutrients
The Buffy coat makes up
Less than 1% of whole blood
The Buffy coat is made up of
Platelets and leukocytes (WBC)
Erythrocytes make up
45% of whole blood
Red blood cells are also called
Erythrocytes
What is the most dense and least dense component in blood when separated by centrifuge
Least dense is plasma, most dense is erythrocytes
Percentage of volume of all formed elements in the blood, attributed by percentage of volume in red blood cells
Hematocrit
What is the hematocrit in males and females
Males= 42-56%, Females=38-46%
The most abundant of the plasma proteins
Albumin
Function of albumin
Retain water in blood and transport hormones
Function of fibrinogen
Help with clot formation
Function of globulins
Transport lipids
What are the main blood proteins
Albumin, fibrinogen, and globulins
Lack nuclei and organelles
Erythrocytes
Erythrocytes transport
Oxygen and carbon dioxide
Erythrocytes contain
Hemoglobin, which binds oxygen and carbon dioxide
What is an important component of hemoglobin
Iron
Average life span of erythrocytes
120 days, broken down in liver
Heme ( hemoglobin without iron) is converted into
Bilirubin, component of bile
Iron is transpired from the
Liver to bone marrow for recycling
Erythrocytes originate in
Red bone marrow
Erythrocytes function how
Anaerobically, not using oxygen they transport
There is a lot of what in the oxygen carrying hemoglobin
Cytoplasm
Main function of erythrocytes
Transport oxygen to tissues
Wrights stain is often used on
Blood smears
Heme components are
Biliverdin in bile of liver, and iron stored by ferritin in liver
Erythrocyte membranes protein and globin proteins are broken down into
Amino acids
