Blood is a
liquid connective tissue
Blood is the
function of life
blood comprised of
plasma, formed blood cells elements, erythrocytes, leukocytes, thrombocytes
Another word for thrombocytes
platelets/fragments
plasma percentage
55%
Formed blood elements percent
45%
Erythrocytes are aka
RBC
Leukocytes aka
wbc
what are platelets needed for
blood clotting
Why is plasma at the top of blood?
The most dense
ORder of blood
PLasma
WBC+PLATELETS
RBCS
communicable disease that affects red blood cells
HIV
How does HIV affect
Attacks the wbc known as the CD4
CD4
AKA Helper T cells, activates the immune system
how DL of cd4 per blood?
1200 DL
How many DL do u need to be diagnosed with aids
200 or less
Hemastasis
Blood clotting
Blood transports
O2, CO2, nutrients, waste, and hormones
blood regulates
body temperature, body PH, electrocyte levels
Blood protects against
foreign microbes and toxins
When blood vessels dilate
heat is released
When blood vessels contract
heat remains inside
Blood Cells are sitting in
plasma
RBCS have
antigens in them
in order for blood to be given, it must be
compatible
plasma is aka
non-living fluid matrix
there are more _____ than ______
rbcs, wbcs
Toxins are
waste such as poison
INtoxicated
poisoned with alcohol
Osmosis
function of blood, movement of water from high to low concentration, type of diffusion
RBCS are
anucleaic
Why are RBCS anucleic
they have a hemoglobin where oxygen is attached. therefore, there is no space for a nucleus
erythrocytes are a type of
red Blood cells
Leukocytes can be
granular or agranular
Granular leukocytes
neutrophilis, eosiphilis, basophilis
Agranular leukocytes
monocytes, lymphocytes
how many types of wbcs do we have?
5
NLMEB
Never, let, monkeys, eat, bananas (most dominant to least dominant)
Neutrophilis, Lymphocytes, Monocytes, Eosiphilis, Basophilis
Neutrophil
Lifespan is 7 hours, function is to defend immune system.
Eosiphilis
Lifespan is 8-12 days, function is to defend against parasites
Basophil
Lifespan a few hours to a few days, function is inflammatory response
B-Lymphcoyte
Memory cells, lifespan is many years, function is antibody production
T-Lymphocyte
Memory cells, lifespan possible many years, function is cellular immune response
Heparin
A substance that slows the formation of blood clotts
Histamine
A chemical in the body that removes allergens out of your body/off your skin
histamine examples
sneezing, tearing up, itching
Thrombus
Made in a particular area and stays there
Embolous
Made in a particular area and moves from original point of origin
Megakarocyte
makes platelets
FOrmed elements
RBCS, platelets, WBC
fluid portion of blood is
91% water
PLasma proteins
7%, albumin, globulin, fibrinogen
plasma solutes
2%, ions, nutrients, waste, products, gases, enzymes, hormones
plasma proteins are
made in the liver
Formation of blood cells is produces in
bone marrow
lymphocytes and monocytes are produced by
lymph nodes, spleen, tonsils,
stem cells
undifferentiated cells
Red bone marrow is located in
end of long bones, and in flat bones
red bone marrow creates
red Blood cells
Red blood cells transport
oxygen
Tonsils is included with the
immune system
Undifferentiated
there, but can become a different type of cell
Hemoglobin attacks
oxygen which makes RBCs scarlet red
blood is ______ after oxygen
brick red
we need oxygen for
cellular respiration which we need for energy
What is RH?
A certain type of protein found on the outside of red blood cells
Hemostasis
Stoppage of bleeding resulting from a break in a blood vessel
3 phases of hemostasis
Vascular spasms, platelet plug formation, coagulation (blood clotting)
Clot
Fibrin forms long threads acting like a net
Synersis
Clot retraction
Fibrinolysis
Dissolution of blood clot
Thrombosis
Unwanted clotting
Embolous
Circulating blood clot
Infarction
Tissues killed as a result of loss of blood supply
Agglutinin
A substance in the blood that causes particles to coagulate and aggregate (antibodies)
Agglutinogen
Antigens that stimulates the production of an agglutinin
People with O blood are called
universal donors
Those with AB blood are called
universal recipient
Type AB has antigen
a and b
Type O has _____ antigens
no antigens
“A” type of antigen
A antigens
B type antigens
B antigens
Type O antigens
No antigens except if you have RH
If you have RH your blood type is
positive
If you have no RH your blood type is
negative
O negative
No antigens, no RH
Only certain combinations are
compatible
