|
State the general functions of the circulatory system
|
*Trasporte oxygen, co2, nutrients, it absorbs hormones, brings materials
*Regulates Temp- absorbs heat without raising temp and absorbs cold wiout lowering temp *Maintaing pH- concentration of hydrogen ions in fluid *protection |
|
|
Identify the major components of the circulatory system
|
Heart
Blood Vessels Blood |
|
|
Formed Elements?!
|
RBC
WBC .... Granular , Agranular, Lymphocyte |
|
|
RBC's
|
99% of all blood cells
*no nucleus,no organelles, hemoglobin (each molecule can carry 4 molecules of o2 because has 4 units of Heme) --> protien- betapolypeptide, Alphapeptide --> Heme-carries o2 *live for 3-4 months because cell membrane gets worn--abrasion and all material in cell spills out due to breakage of membrane and they all die! *a small degree carry CO2 |
|
|
Protein
|
collection of amino acids (2o AA in system ...AA recycled and reused
|
|
|
WBC's
|
*15,000 mm3
have no hemoglobin, 5 different WBC / into 2 maj groups *granular - lobe nucleus-->(bi/multilobed) 1.neutrophil 2.Eosinophil 3.Basophil *agranular- without vary little or no granules, 1 nuclues 4.monocyte 5.lymphocyte |
|
|
WBC Granular Neutrophil (myeloid)
|
most numerus (60-70% of WBC)
Slide (cytoplasm WHITE) nucleus 3-6 lobes *Function- phagocytosis |
|
|
WBC Granular Eosinophil
(myloid) |
2-4% of WBC
*Function- phagocytosis, MAINLY ALLERGIC RESPONSES ! |
|
|
WBC Granular BASOPhil
(myloid) |
many granules .5-1% of WBC
*Function- phagocytosis, allergic responses, MAINLY IMMUNITY! |
|
|
WBC Agranular MOnocyte
(myloid) |
3-8% of WBC
*1 large nucleus (slide, kidney shaped) *Function- phagocytosis (moves out of blood vessels and into C.T. becoming macrophage) |
|
|
WBC Agranular Lymocyte
(lymphoid) |
20-25% of WBC
Nucleus takes up most of cell *2 Types **T-Cell-->killer cell/ protecting body **B-Cell --> plasma cell/ manufactures antibodies in immune reaction, gets rid of antigens by neutralizgin them |
|
|
Formed Element
|
blood cells, hormones, enzymes, waste ...
|
|
|
Phagocyte
|
ingest and DESTROY....derrr
|
|
|
Hemoglobin
|
O2 attaches to and gets carried
|
|
|
Hemopoeisis
|
synthesis of blood cells
|
|
|
Erythropoiesis
|
Synthesis of RBCs
|
|
|
Thrombocyte/ platelet
|
*250-400,000 per mm3
from stem cell, progenetor (beginning), differentiates into megacarriaocyte- breaks apart to 2-3,000 little fragments (platelets)--> very small--only live 5-9 days -clotting process --> hemostasis |
|
|
hemostasis
|
clotting process...stops blood at area of damage to keep it from continuing to veins..
|
|
|
99% of blood vessels are??`
|
capillaries ..constantly being torn and broken
|
|
|
rough of how many RBC per hour
|
10 million
|
|
|
hemocytoblast
|
progenetor ..differentiation ..gets info from DNA and will becoming all other cells (myoloid/lymphoid stem cells) that body needs
|
|
|
Plasma Proteins
|
*Albumins
*Globulins *Fibrinogen |
|
|
Plasma protein Albumins
|
necessary for osmotic pressure (regulates amount of blood/fluid leaving) B.P. ..????
|
|
|
Plasma Protein Globulins
|
reactions for immunity
|
|
|
Fibrinogen
|
necessary in clotting procedure when damage in vessel creating clot
|
|
|
Other substances in Plasma
|
*7-8% solid material of plasma---protein
*91% water *1-1.5 intracellular fluid/ extracellular fluid |
|
|
Blood %'s
|
Plasma 55%
Formed Elements 45% |
|
|
leukocyte
