A&P 2 - 19.1-19.3 Blood
By helping to maintain pH and body temperature, blood functions in the maintenance of
homeostasis
Blood is comprised of cells and cell fragments, together called "formed elements", suspended in a liquid matrix called blood
plasma
About 55% of the blood volume consists of Blank 1Blank 1, and approximately 45%. of the blood volume consists of Blank 2 , elements.
plasma formed
The complex mixture of water, proteins, nutrients, electrolytes, wastes, hormones and gases is called
plasma or matrix
What is plasma? The liquid component of the blood plus the platelets A protein that cleaves prothrombin to form thrombin An enzyme found in blood that dissolves blood clots The water, proteins, nutrients, wastes, hormones and gases in blood
D
Blood, a type of connective tissue, is composed of ______. matrix (plasma) and formed elements epithelium and free space astrocytes and serum smooth muscle and epithelium
A
The globulins are important plasma proteins that functions primarily in ______. immunity hormonal regulation gas transport pH control
A
Blood's homeostatic functions include ______. Select all that apply. regulating body temperature regulating pH regulation of sleep/wake cycles protection against infection
A B D
Indicate the three primary types of plasma proteins. Select all that apply. Fibrinogen Albumin Globin Globulin Collagen
A B D
Blood's homeostatic functions include ______. Select all that apply. regulating pH regulation of sleep/wake cycles protection against infection regulating body temperature
A C D
Describe how blood helps maintain homeostasis. Select all that apply. Transport of carbon dioxide Secretion of neuropeptides Transport of nutrients Limits spread of pathogens Stabilization of body fluids
A C D E
Blood consists of a matrix of plasma and cells; blood is a subtype of ______ tissue. epithelial connective muscle nerve
B
By volume, blood is typically ______% plasma and ______% formed elements. 45, 55 55, 45
B
Indicate which type of plasma protein has a role in immunity and the immune response. Albumin Globulins Fibrinogen
B
List the three primary types of plasma proteins. Collagen, albumin, globulin Albumin, fibrinogen, globulin Fibrinogen, globin, collagen
B
Most adults have ______ liters of blood. 7 to 9 4 to 6 2 to 4 1 to 2
B
The most abundant type of molecule in blood plasma is ______. oxygen protein glucose
B
The type of plasma protein that forms the threadlike proteins formed in blood clotting is ______. globulin fibrinogen collagen albumin
B
Regulation of pH and body temperature, transport and protection are all functions of the ______. nervous system respiratory system circulatory system urinary system
C
An adult patient is brought into the emergency room of a local hospital. The EMTs report the patient lost about 300 cc (cubic centimeters or milliliters) of blood. Is this life-threatening? No, most adults have more than 7 liters of blood so a loss of 300 cc would not be life threatening. Yes, 300 cc represents about 1/3 of the blood's volume. Yes, 300 cc represents about 1/6 of the body's total blood volume of 2 liters. No, most adults have 4-6 liters of blood so a loss of 300 cc would not be life threatening.
D
Name the plasma protein that is important in regulating the movement of water between the tissues and the blood. Globulin Collagen Fibrinogen Albumin
D
Plasma proteins are _____ in the blood. the least abundant suspended substances responsible for carrying oxygen found mainly in the tissues and occasionally the most abundant suspended substances
D
What is fibrinogen? A plasma protein that transports substances in the blood An enzyme in red blood cells that activates carbon dioxide One of the factors that determines blood type A plasma protein that plays a role in clot formation
D
Maintaining plasma colloid osmotic pressure is primarily accomplished by the plasma protein called
albumin
The cells and cell fragments of blood are called Blank 1Blank 1, Blank 2; the liquid matrix of blood is called plasma.
