what is a connective tissue composed of a liquid matrix called plasma that dissolves and suspends various cells and cell fragments
|
blood
|
|
|
what is interstitial fluid
|
a fluid that baths body cells
|
|
|
blood transports oxygen from lungs and nutrients from the GI tract to body cells. t or f
|
true
|
|
|
carbon dioxide and other wastes move in the reverse direction...what is this direction
|
from body cells into the interstitial fluid and then into blood
|
|
|
what are the functions of the blood
|
transport
regulation protection |
|
|
what happens during the transport process of blood?
|
1. O2 from lungs cells
2. CO2 from cells lungs 3. Nutrients from GI Tract cells 4. Heat/Waste products from cells 5. Hormones from endocrine glands to other body cells |
|
|
what happens during the regulation process of blood?
|
1. pH thru buffers (weak acids and bases that help to resists changes in pH)
2. Temperature thru heat a. Absorbing/coolant properties of its H2O content b. Variable rate of flow thru skin where excess heat is lost to environment |
|
|
what happens during the protection process of blood?
|
1. Clotting mechanism protects against blood loss
2. Certain phagocytic WBCs and plasma proteins (antibodies) protect against foreign microbes and toxins |
|
|
what is the pH range of blood?
|
7.4 (7.35-7.45 slightly alkaline
|
|
|
what are the blood volumes of both males and females?
|
Male 5-6 L, Female 4-5 L
|
|
|
what are the proteins of plasma?
|
albumins
globulins fibrnogen (FAG) |
|
|
which blood protein functions in blood clotting?
|
fibrinogen
|
|
|
which blood protein is the most abundant?
|
albumins
|
|
|
which blood protein is responsible for maintaining blood volume by maintaining H2O balance between blood and tissues?
|
albumins
|
|
|
which blood protein function in immune response?
|
globulins
|
|
|
red blood cells have no nucleus or organells. t or f
|
true
|
|
|
which blood cells are highly specialized for transporting oxygen
|
red blood cells
|
|
|
is hemoglobin present in rbc or wbc?
|
red blood cells
|
|
|
white blood cells cannot reproduce or carry on metabolic activity. t or f
|
false - rbc
|
|
|
white blood cells are also called erythrocytes. t or f
|
false
|
|
|
where are biconcave discs present?
|
red blood cells
|
|
|
what is the process by which formed elements of blood develop
|
hemopoisesis/hematopoiesis
|
|
|
name 5 WBC
|
1. Neutrophils
2. Lymphocytes 3. Monocytes 4. Eosinophils 5. Basophils |
|
|
name the structural characteristics of RBCs.
|
i. Biconcave discs
ii. No nucleus or organelles iii. Cannot reproduce or carry on metabolic activity iv. Selectively permeable strong plasma membrane that allows RBC to deform without rupturing |
|
|
what is globin?
|
one protein found in the structure of hemoglobin
|
|
|
what are the structural characteristics of red blood cells
|
i. Biconcave discs
ii. No nucleus or organelles iii. Cannot reproduce or carry on metabolic activity iv. Selectively permeable strong plasma membrane that allows RBC to deform without rupturing v. Highly specialized for transporting oxygen vi. RBCs do not consume any of the oxygen they transport vii. Hemoglobin (Hgb) = oxygen carrying protein that gives whole blood its red color viii. Hgb carries O2 to cells and CO2 from cells to lungs (CO2 is transported mostly by blood plasma) |
|
|
where does erythropoiesis take place
|
in red bone marrow
ner the end of the develomental process of blood stem cells 1-2 days after leaving the bone marrow a reticulocyte develops into an erythrocyte |

false
|
|
|
white blood cells are classified as glanular t or f
|
true
|
