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
