Blood and Circulatory System PPT Flashcards
What are the (4) Blood Vessels
Arteries Arterioles Capillaries Small Venules Large Veins
What are (3) important characteristics of blood
- Major transport system for oxygen, glucose, and other nutrients, hormones, electrolytes, cells wastes
- Carries antibodies and WBC for rapid removal of foreign material
- Controls body temp. by distributing core heat throughout the peripheral tissue
Blood components and percentage-
Blood consists of water and its dissolved solutes (55% of the whole blood volume)
Composed of cells or formed elements, erythrocytes, leukocytes and thrombocytes (45%)
What are the (3) components of plasma (clear, yellowish fluid remaining after cells removed)
- Albumin
- Antibodies
- Fibrinogen (clotting)
What is left after cells and fibrinogen are removed?
Serum Fluid
Where do RBC originate from?
Red Bone Marrow
flat and irregular bones, ribs, vertebrae, sternum and pelvis
Blood cells develop from where?
Single Stem Cells, differentiate, then mature into specialized functional cells
Indicates the proportions of specific types of WBC’s in the blood assists in making a diagnosis.
Differential Count
Bacteria infection or Inflammatory condition has a increase in what?
Neutrophils
Allergic reaction has an increase in what?
Eosinophil
Includes total RCS, WBC and platelet counts ad morphology
CBC- Complete blood count
Aid in blood clotting process by sticking to damaged tissue or to each other
Thrombocytes (platelets)
True or False
Men have a lower amount of hematocrit than females
False- Men have a higher number of hematocrit
42-52% and women have 37-47%
What can be an indicator of anemia?
Hematocrit- proportion of cells (erythrocytes) in blood, indicates viscosity of the blood- low RBC count may be indicator of anemia.
Elevated hematocrit can indicate what?
Loss of fluid (dehydration) or excess red blood cells
