What happens when the body tissues start to decrease
The kidneys senses the need for additional oxygen and sense the need for additional oxygen and then secretes erythropoietin so it can stimulate red bone marrow produce rbc
Erythropoietin
Is responsible for production of RBc
when oxygen in the body tissues decrease in oxygen the kidneys secrete this hormone to stimulate rbc in red bone marrow
coagulation aka blood clotting
a blood forms by a series of chemical reactions forming a net like structure called fibrin as blood flows through fibrin catches the large particles which help form blood clot it seals the opening
formation of platelet plugs
platelets become sticky, they adhere to the inner lining of damaged vessel as well as each other forming a platelet plug diminishing bleeding at site of injury they secrete chemical that activate blood clotting factors
blood vessel spasm
healing mode seals the cut, smooth muscles in the vessels wall contract and constrict
what are the three events during hemostasis
blood vessel spasm,formation of a platelet plug,blood clotting
whats the process that stops bleeding
Hemostasis
Agranulocytes
do not contain granules ex monocytes and lymphocytes
when you getting cbc the percentage is called what ?
Differential count which is significant diagnostically because it tells what wbc is involve
whats included in cbc
rbc,wbc,platelets,hemoglobin ,hematocritic
cbc
complete blood count
hematocrit
percentage of blood in a sample
platelets
produced in red bone marrow
stop the flow of blood
monocytes
Are the eaters
where are lymphocytes produced
in red bone marrow
plays a role in the immune response
Eosinophils
has an inflammatory response secretes chemicals that destroy certain parasites and increased in person
Basophils
play a role inflammatory response they release histamine as well as release heparin which is thought to reduce formation of clots in lungs and liver
Neutrophils
quickly moves to site of infection and begin phagocytosis of pathogens
ex a pimple with pus is dead neutrophils
what are Granulocytes
white blood cells that contain Granulocytes, which are Neutrophils,basophils,Eosinophils
white blood cells aka Leukocytes
protects body from pathogens by phagocytosis
If you have a deficiency in RBC
creates anemia
Macrophages
They line the liver and spleen and remove rbc from blood by phagocytosis
HOw long rbc last
120 days
hopoxemia
02 deficiency
what blood is deoxygenated what does it look lik e
The blood is dark blue/red
when blood has oxygen what does it look like
Its bright red
What is essential for hemoglobin
iron,vitaminb12,folic acid
Rbc
Has protein molecule Hemoglobin,which transfer oxygen and small amounts of carbon dioxide
rbc cells aka Erythrocytes
Transport oxygen to all cells,The shapes make them flexible
what is serum
Its plasma minus the clotting
WHat does plasma proteins have
Albumin, clotting factors antibodies and complements
plasma
liquid portion of blood
pale yellowish color
mostly water
has proteins, ions, nutrients gases and waste
composition of blood contain
palsma and cells Aka corpuscles
Where does lymphocyte and monocyte
originate in the bone marrow but some mature in lymphatic tissue
How does the stem cell differentiate
The stem cell differentiates into Rbc or Wbc or platelet
Red bonemarrow
Produces all three types of blood cells from one cell the stem cell
Hematopoiesis
Production of red blood cells
blood is viscous
3 to 5 times more then water
meaning its thicker
Whats the function of blood?
Protection from infection,Clotting factors protect from excessive bleeding
What does the blood Transport
Oxygen to lungs
Waste from cells, to the organs for elimination from the body, Ions, nutrients and hormones are transport in blood
blood
flows through a closed system,The force that pushes blood through the vessels is th epumping action the heart
blood
Three functions, Transport,Regulation,Protection
