Blood Physiology Rhodes Flashcards
Anemias caused by decreased or faulty erythrocyte production?
- sickle cell anemia
- pernicious anemia
- iron deficiency anemia
- anemia of innflammation
Anemias caused by a loss or destruction of blood?
- hemorrhagic anemia
- hemolytic anemia
Hemostasis
Arrest of bleeding
Homeostasis
Maintenance of a stable internal inviroment
Hemorrhage
The failure to stop bleeding after injury. It can quickly lead to bleeding to death
Hemolysis
Premature destruction of erythrocytes
The formed elements of blood are:
- red bloodcells
- white bloodcells
- platelets
The intercellular matter of blood are:
- plasma
Plasma
Liquid component of blood
Most abundant organic constituents of the plasma are:
Plasma proteins
What does the buffy coat contain?
White bloodcells and platelets
Plasmapheresis
Fresh frozen plasma (FFP) can be stored and used for therapeutic plasma exchange called plasmapheresis
Heelstick
In newborns, blood is collected by a heelstick
Anticoagulants:
- ethylenediaminetetra-acetic acid (EDTA)
- citrate
- heparin
What is the primary function of albumin?
To maintain oncotic pressure
Oncotic pressure
- Is about 0.5% of the total osmotic pressure.
- It is also called colloidal osmotic pressure.
Where is albumin produced?
Liver
Where is Globulins produced?
In the liver
Where is Gamma globulins produced?
By lymphoid tissue
Where is fibrinogen synthesized?
In the liver
Primary function of albumin:
Maintain oncotic pressure (colloidal osmotic blood pressure)
Atherosclerosis
Cholesterol plaque buildup in arterial walls
