1-Cardiovascular System: Blood Flashcards
The 3 plasma proteins
Albumin - maintain blood osmotic pressure
Globulin
Fibrinogen
3 basic functions of blood
Transportation
Regulation - pH, body temp, water content of cells
Protection - clotting, wbcs
Plasma (liquid extra cellular matrix) proteins are synthesized by –
Liver
Formed elements consist of which 3 elements
RBCs
WBCs
Platelets
Name the 5 wbcs
Never let monkeys eat bananas
Neutrophils Lymphocytes Monocytes Eosinophils Basophils
– is the volume percentage of Rbcs in blood
Hematocrit
-higher in males
— is HIGH hematocrit (% rbcs) => increase viscosity of blood
Polycythemia (many)
Pluripotent stem cells differentiate into
Myeloid stem cells => Rbcs, platelets, neutrophils; do not divide once they leave bone marrow
Lymphoid stem cells => complete in lymphatic tissue
– is development of formed elements
Hemopoiesis
Name the 3 hemopoietic growth factors (for the 3 formed elements)
Erythropoietin
Thrombopoietin - platelet formation (thrombosis)
Cytokines - wbcs
1 hemoglobin molecule consists of 4 – (polypeptide chains) and one – bound to each chain, with one oxygen bound to each
4 globin (protein) 4 heme (contains iron and oxygen)
How is heme (part of Rbcs) broken down
Iron transported by transferrin to red bone marrow for erythropoiesis
Non-iron portion => bilirubin => liver => bile
Formation of RBC:
Proerythroblast ejects nucleus => becomes – (immature RBC) => enter bloodstream to become mature erythrocytes
Reticulocyte
Lack of oxygen is –
Speeds development of reticulocytes, or immature Rbcs
Hypoxia
Unlike erythrocytes/Rbcs, – HAVE a nucleus
Leukocyte / WBC
