3 parts/layers to centrifuged blood and what is in each part:
(PBH) Ans: Plasma - Upper layer- 55% (water, dissolved gasses,

nutrients, waste products, proteins)- albumin, sodium, and
urea
Guru01 - Stuvia
Buffy Coat - middle layer- less than 1% (WBCs and Platelets)
Expert
Hematocrit (Erythrocyte) - lowermost layer- 45% (RBC)
Plasma is made up of mostly water. Inside the water we have
some dissolved substances like protein.
The 3 formed elements of centrifuged blood are: Ans: White
Blood Cells aka Leukocyte
Red Blood Cells aka Erythrocyte
Platelets aka Thrombocytes
Albumin Ans: constitutes 60% influences the viscosity and
osmolarity of blood it also creates blood pressure.
To make an RBC you need: Ans: EPO or erythropoietin
(released from kidney due to low oxygen in the blood –
hypoxemia); amino acids; iron (Ferrin); vitamin B12
, 2
Pernicious Ans: Results from a lack of intrinsic factor from
the stomach that helps with the absorption of Vitamin B12.
*** leukocytes..... Never- Neutrophils
Let- Lymphocytes
My-Monocytes
Engine- Eosinophils

Blow- Basophils Ans: (Never) Neutrophils 60% Microphages
Guru01 - Stuvia
(phagocytic), bacterial infections.
Expert
(Let) Lymphocytes 30% T and B-cells, mount immune response,
cancer cells, viruses
(My) Monocytes- 8% Macrophages phagocytize pathogens, dead
neutrophils, and debris of dead cells
(Engine) Eosinophils 3% Parasitic worms, phagocytize antigen-
antibody complexes, allergies, and inflammatory chemicals
(Blow) Basophils >1% Allergic reactions, secrete histamine,
secrete heparin
Two categories of leukocytes: Ans: Granulocyte: -phils;
Neutrophils, Basophils, Eosinophils. (BEN is G)
o Agranulocytes: -cytes; Monocytes, Lymphocytes
What happens In the presence of Ca2+ Ans: In the presence
of Ca2+, factor X combines with factor III and produces the
enzyme prothrombin activator. This converts a plasma protein
