platelet - ANSWERclot activating substances and helps in formation of clot forming
Proteins in plasma - ANSWERAlbumins, globulins, fibrinogen, prothrombin
Globulins have three sub types - ANSWERAlpha Beta Gamma-Immunoglobulin=
antibodies
Fibrinogen and Prothrombin do what - ANSWERBlood clot
Never Let Monkeys Eat Bananas - ANSWERNeutrophil, Lymphocyte, Monocyte,
Eosinophil, Basophil
Blood is made up of two key components, what are they? - ANSWERPlasma and
formed elements
Blood is a type of - ANSWERTissue, specifically connective tissue
*made up of cells that have a specific function*
The functions of blood consist of... - ANSWERTransportation and heat-regulation
Discuss bloods function of regulating heat - ANSWERPlasma within the blood
consists of mainly 91% water, initiating a high specific heat of water
Low hematocrit could presume - ANSWERThere is not a good supply of oxygen, and
red blood cells are dying
High hematocrit could presume - ANSWERA low supply of oxygen, so the production
of RBC's increase to more than usual
Albumin (plasma) - ANSWERensure tenacity and shape and act as a binding protein
, Globulin (plasma) - ANSWERgives immunity and is in both PLASMA AND SERUM
Fibrinogen (plasma) - ANSWERClotting and works with platelets
Formed elements consist of - ANSWERRed blood cells, white blood cells, and
platelets (cell fragments)
Whole blood %'s - ANSWERPlasma 55%
Formed elements 45%
Plasma %'s - ANSWER91% water
7% proteins
2% other solutes
Formed elements %'s - ANSWER99% red blood cells
<1% white blood cells
<1% platelets
Less body fat = ? amount of blood per kilogram - ANSWERMore blood
Discuss hematocrit - ANSWERHematocrit is knows as the packed cell value (PCV)
-45% is the hematocrit
-Hematocrit is the volume percent of RED BLOOD CELLS in whole blood
The buffy coat is made up of - ANSWERleukocytes and platelets
Serum - ANSWERno clotting elements are located in serum or blood cells
-needs to be treated with anti-clot
Structure of red blood cells - ANSWER-NO NUCLEUS
-No organelles
-Thicker on the outside, thinner on the inside
-donut looking
-shape increases surface area
-Hemoglobin (protein)
Function of red blood cells - ANSWERtransport oxygen and carbon dioxide
depending on the hemoglobin
Carbonic anhydrase - ANSWER-Enzyme in RBC
-catalyzes reaction that binds together carbon dioxide and water to form *Carbonic
acid*
Formula for carbonic acid - ANSWERCO2 + water = H2CO3
Carbonic acid generates bicarbonate ions, the formula is... - ANSWERHCO3 (-) +
H+ = H2CO3 + H2O
Erythropoiesis - ANSWERBegins in red bone marrow with the help of
hemocytoblasts which eventually created RBC's via multiple stages
