-
blood leaves the heart going to all parts of the body via the
aorta
-
normal red blood cell count is about
5000000 per cubic millimeter
-
Type B blood contains what antibodies?
A
-
prothrombinand fibrinogen are
clotting protiens that are normally found in the plasma of the blood
-
How many types of wbcs are there
5
-
someone with tyoe AB blood can receive blood from a person with type
A B O
-
the chambers of the heart are lined with
endocardium
-
blood returning from most of the areas of the body enders which chamber of the heart?
right atrium
-
the pulmonary artery is connected to the
right ventricle
-
veins (not arteries) have
valves along the inner walls
-
the systolic pressure is the pressure at the height of a
ventricular contraction
-
only in the region of the capillaries that an exchange occur between
the plasma of the blood and the surrounding tissue fluid
-
-
heart
pump for circulatory system
-
vessels
circulate blood to and from the heart
-
partterns of circulation
different pathways that vellses follow
-
lymphatics
help tissue fluid back to normal patterns of circulation
-
RBC erythrocytes
made in flat bones
-
WBC luekeocytes
made in red bone marrow and lymphnoid tissue
-
Plasma makes up how much and how much is RBCand WBC
- 45% rbc and wbc
- 55% plasma
-
plasma protien
- serum globulin- immulogical responses.
- help with fluids
-
rbc
- have no nucleus and disk like
- transports oxygen to the body and co2 away from the cells. made possible by hemoglobin.
- live 3-4 months. removed by liver and spleen
-
BP
smallest cells, clotting mechanism.
-
WBC granular leukocytes
- made in bone marrow.
- basophil, neutrophil, and eosinophil.
- Have a nucleus.
Protects body against infection
-
monocytes
remove large particles like broken down tissue cells.
-
WBC
engolphing forign substances and make antibodies.
-
antigen
- substances (protien) stimulate organisms immune system to make antibody
- found in rbc
-
antibody
- produced by immune system that destroys or innactivats a particular antigen
- found in plasma
-
agultination
process of blood clotting
-
what starts the clotting process
throblplastin released by damaged bp
-
functions of the heart
creates pressure inorder to pump the blood through out the body
-
heart lies beneath the
sternum surrounded by the rib cage
-
paracaditis
inflamation of the sac the heart sits in
-
layers of the heart
endocardium(inner), epicardium(outer layer), myocardium (middle)
-
atria recive
blood from the body
-
veins
bring blood to heart
-
artery
take blood away from the heart
-
superior vena cava
- drains from head into the right atrium
- lots of co2 and little oxygen
-
4 pulmonary veins dump into
left atrium into the left vetricle which is pushed throughout the body
-
heart beat order
- sa node
- av node
- bundle of his
- purkinje fibers
-
artieries
carry blood away from the heart
-
layers of veins and arteries
tunica intama, media, anvatitia
-
pressure
the pressure within the vessels
-
systolic pressure
squeezing of the heart
-
diastole
ventricular relaxation
-
radial
curated
temporal
- is in radial bone by hand
- in neck
- in the head
-
pulmonary circut
- out of right ventricle (heart) into the lungs
- deoxgenated
- returned to heart via pulmonary veins
- oxygenated
-
portal circulation
- drainage of gastrointestinal area going into portal vein into the liver.
- leave liver in a large hepatic vein.
-
fetal circulation
- unique cuz of non functional systems
- no need for digestive and respiratory system
-
2 umbilical arteries and 1 umbilical vein make
the umbilical cord
-
foramen ovale
hole in the heart that sends blood from the right to left atrium
-
ductus arterious
short vessel that connects the pulmonary artery to the arota. bypassing lungs
-
functions of lymphatics
important role in circulation.
