into blood cells (W2)

Erythrocytes

red blood cells

transports Co2, O2

95% of the volume of blood cells

no nucleus

Leukocytes

white blood cells

body's defence system

Thrombocytes

platelets

-prevent fluid loss when blood vessel damaged

-from in tempoary paches

Function of blood

Transports: O2 , CO2, nutrients, wast, and hormones

Regulates: body pH, body temp(98.6)

Protection against foreign microbes and toxins

Osmosis (balance)

Plasma protein

is 7% , contains

Albumin 60%- prevents leaking

Globulin 35% -Abtibodies

Fibrinogen 4%- clotting

Plasma solutes 2%

Ions, nutrients, waste products. gases, enzymes, hormons

Hematopoiesis

the production of red blood cells in red bone marrow

hemoglobin: Heme & Globin

heme: binds O2

globin: binds CO2

Hemoglobin

Responsible for red color of blood

Heme- made of iron

Globin- made from 4 amino acids chains

(for every iron atom there are O2 atoms that are loosely attached.)

Oxyhemoglobin (HbO2)

is when hemoglobin combines with O2 in the lungs

Methemoglobin

unable to transport O2 because iron is in a Ferric state instead of Ferrous state

Ferric

Fe (iron) +++ (3 positives)

Ferrous

what we want

Fe (iron) ++ (2 positives)

Carboxyhemoglobin

combination of carbon monoxde and hemoglobin CO+ Hb (hemoglobin) =COHb

biliverdin

-remaining wast from Hb

-green in color ]

transported to the liver then the gall bladder excreted with the bile

Urobilinogen

gives feces brown color and urine yellow color

last reduction

Granulated leukocytes

Neutrophils

Eosinophils

Basophils

Neutrophils(WBC)

1st to injury sites

highly mobile

Phagocytize(surrounds) foreign substances

Eosinophils(WBC)

produce histamines (parasitic infection)

Basophils (WBC)

produce heparin, histamines, serotonin

Agranular leukocytes

Monocytes, Lymphocytes

Monocytes(WBC)

-Phagocytize bacteria and cellular debris

-largest WBC because of that lives longer

Lymphocytes

-antegnes that help develop immunity
