hat is the liquid part of blood called?
plasma
what does plasma do?
1 carries substances such as vitamens minerals amino acids glucose which absorb from teh digestive system and transport to the cells. Cells recieve nourishment from disolved substances caried in the plasma

plasma gets its nutrients or absorbs its nutrients where?
From teh digestive system
cells recieve nourishment from ….. substances carried in the plasma
disolved
the functions of plasma proteins?
some of the proteins in the palsma are essential in formation of blood clotes
Anotehr protein called albumin osmotic pressue between plasma and blood cells and between plasma and tissue
Other proteins called antibodiies help teh body fight diseases
which one of those proteins do we have in oru body naturally without our body having to make it in certain circumstances?
Another protein where we have them naturally and also make them at certain times?
albumin, antibodies
red blood cell is a little more than a?
cell membrane filled with hemoglobin
some white blood cells like ……. Shown in blue engulf and destroy …… ……
phagocyte, invading microorganisms
inactive platelets such as the yellow object derive their name from the fact that they look like? they are …… and contain …… that are involed in the clotting proccess
little plates, colorless and contain chemicals
the platelets change cshape during the …… procces
clotiing
when activated the plate lets settle and spread on the?
substrate
red blood cells are also called?, white blood cells are also called?
erythrocytes, leukocytes
shape of red blood wbc and platelets?
disk shaoed and concave on both sides, has a iregular shape, they are not whole cells like little plates and has rough surfaces
when do platelets become rough and get spiky projections?
when tehy are activated
so in theory platelets can change their ……
shape
Function?
It tarnsports o2 to a greater degree and co2 to a lesser degree which means trabsports less co2
Help defend teh body against diseases
Essential to the formation of blood clots
do they have hb?
uep nope nope t
their colors?
red color colorless colorless
their numbers?
each cubic milimeter of blodo contains 4 mil
Contains about 7000
Contains about half of a million
their sizes?
its smaller than wbc, its larger than rbc , they are fragments of very large cells that were formed in the bone marrow
presence of nuceuls?
lacks, has, lacks
life span?
it has a short life span 120-130 days, may function for years, ot has a life span of 7-12 days
posibility of division?
cant divide, it can divide, cannot divide
why cant rbc divide?
cuz those bastards dont have a nucleaus
types?
ony has omne type, has several types like neutruphlis macrophage and natural killer cells , only 1 type
red blood cells are formed in the ….. ….. …. Of bones
red bone marrow
….. rbc synthesize large amount of an …. Containing protein called ……
imature, iron, hb
during teh formation of rbc its …. And …. Disintigrate

hemoglobin where is it made?
its made in bone m,arrow
do imature redblod cells have nucleaus and organeles?
yesit does
hb is tehj molecule that actually transports …. And to a lesser degree ……
o2, co2
so the rbc hemoglobin carries most of the o2 then who transports and carries the co2?
plasma does
rbc can divide and they dont surivie that long just 120-130 day?
cuz they dont ahve nucleic
wbc where are they formed in? But some must travel where to mature?
red bone marrow, lymph nodes thymus or the spleen
white blood cells can squeeze their way thorugh the opening ins the?
walls of blood vessels and into teh intercellular fluid
do blod vessels have openings?
yes they do
By doing so they can?
reach teh site of infection and help destroy the invading microorganisms
the w,bc shown in teh figure is called?
phagocyte
phagocytes def? in the pic which one is teh phagocyte? Which one is the microorganism?
are cells that engullf and estroyes ferign matter or microorganisms , the peanut shpaed i the phagocyte but the microorganism is the yellow ball
when a person has an infection the number of white blood cells ….., why can they divide?
can double , cuz they have nuclei
anotehr type of white blood cells produces?
antibodies
antibodies def?
are proteins that help destroy subsatnces such as bacteria nad viruses that enetr the body and cause disease
explain how the rbc and wbc and platelets structures relate to their function
teh concave shape of rbc gives the, a great amount fo surafgce area in which to absrob and release oxygen
Wbc ability to change shaope helops them move through vessel walls and engul pathogens platelets have a rough surface that hels form blood clots
blood clot?
is a mass of interwoven fibers and blood cells that prevent exces loss of blood from a wound
the stages and structures involved in teh clotting procces
platelets congregate at the damafged site sticking together and forming a small pluug
The vessels constricts slowing blood flow to the area, then special clotting factors are released from the platelets and damaged tissue
These factors begin a series of chemical reaction that occur at the site of the bleeding
The last step in this series bring about the production of a protein caled fibrn, fibrin molecuiles consists iof long sticky chains
Thse chains form a net tah ttraps red blood cells, and the mass of fibrin and red bloos cells hardens into a clot or a scab
special clotng afctors are released from?
platelets and damaged tissue
the last steps in this series is to bring about the production of a ….. called?
Protein fibrin
fibrin m,olecules consists of a ….. and ….
Long and sticky
the mass of fibrin and red blood cells hardens into a …. Or ….
clot, scab
platelets release?
cloottinf protein(enzyme)
fibrin has a shape of a …
net
teh fibrin net tarps in ….. and ….
rbc and platelets
The relase of enzymes from plateklets at the site of damaged blood vessel initiates a …… ……
clotting cascasde
that example was the examel of forming a clot on a?
blood vessel
hemophilia?
is a disorder in where they dont have all teh cloting proteins so blood doenst stop so easily bt today people are treated with ionjection of the missing clotting factors
what might be soem advantages and disadvantages of hemophilia?
they would be less likely to suffer from strojkes and poor blood circulations
But a eprson with it coudl bleed to death
blood type is determiend by the type of ….. present on the …. Of the rbc
antigen, surface
antigen is a?
substance taht stimulates an immune respone
antigens tahta re normaly present in a persons body provoke no response but they do provoke a respoinse when? and in response what do they produce?
a foreign antigen enters the body, antibodies
antigen is an abriviaitin for?
antibody generating substance
what determiens teh compatibility of transfuion?
the presence of antigens on the red blood cells and antibodies in the plasma determine compatibility
in the early …., ….. ….. used blood taken from his laboratory …… and made observations he noticed that when mixing blood sometimes resulted in the cell to ….. togetehr orr ……..
1900, karl landsteiner, , workers clump, agglutinating
what happens when sampels of two diffrent blood types mixed together?
reactions occur between the antigens on the red blood cells and teh antibodies in the plasma casingf cells to agglutinate
what happens when the samples of the same blood type are mixed?
no reaction occursd and the blod cells do not agglutinate
Antigens are technically made where when what are developing?
in the bone marrow when rbc are developing
what are the three most important antigens?
a b and rh
the a b o systems of blood sypes are based on the?
a and b antigens
The abo system
is a means of classifying blood by teh antigenst located on teh surafce of the red blood cells , and teh antibodies circulating in the plasma
a rbc may carry which antigens?
a or b or both or none
how many blood types fo we have acording. To antigens?
4
a and b and ab and o antigens? Antibodies? Get blood? Can give blood?
A b ab and o, b a none a and b , a and o b and o a b ab and o just o
A and ab b and ab ab a b ab and o
o are called? Ab are called?
o are called universal donors, universal recieptents
why are ab recieptents?
cuz they dont have antibodies
why are o universal donors?
cuz they dont have antigens i
if we give blood from a to b what happens?
the antibodies of plasma of b attacks the antigens of a And blood will agulinate
And the antibodies in the plasma of a wil cause an antigen antibody reaction which will cause the body to forma aggluniated blood that wil blockl the flow of the blood through the vessels
for transfusion receiptents must recieve blood that is compatibel wiqtgh their own why?
to avboid blood agglutinate
we have the rh system.
Its an antigen that is soemtimes present ion the surface of red blood cells
why is it named the rh factor?
its named after the rhesus monkey in which it was first discovered
how much percent of united states population is rh positeve? Which means rh is?
85%, present
people who dont ahev teh rh entigen are called?
rh-
what happens when a reciptent has negative and teh donor is positeve?
the antibodies may react withg the antigen and agglutination will ocure
befpore transfer of blood what is very important to know?
blood type and rh factopr
people who ahve rh+ cannot produce?
anti rh antibodies
people who have rh- can produce?
anti rh antibodies
if O- have all three antibodies then when doesnt the body panick when we give siomebody it?
cuz in transfusion when we get the blood out of the body of the donor we take very little ammount of plasma if we do get alot of plasma wef filter it out
how many anitbodies do we have? What ar ethey?
we have 3 , a and b an rh
Why doesnt ab+ have any antibodies?
cuz it has all antigens it knows every type of blood why would it get scared so it doesnt have antibodies
the most seriopus problems of rh incompatibality ocrues during?
pregnancy
rh factor during pregnancy?
the sperm is teh donor and teh egg is teh reciever so + blood sperm cant be given to -blood egg
if teh blood of teh fetus is rh- it doesnt not affct th fetus whether the blood is?
rh + or rh- cuz the baby doesnt have the antigen rather it has the antibodies
