blood leaves the heart going to all parts of the body via the
normal red blood cell count is about
5000000 per cubic millimeter
Type B blood contains what antibodies?
prothrombinand fibrinogen are
clotting protiens that are normally found in the plasma of the blood
How many types of wbcs are there
someone with tyoe AB blood can receive blood from a person with type
A B O
the chambers of the heart are lined with
blood returning from most of the areas of the body enders which chamber of the heart?
the pulmonary artery is connected to the
veins (not arteries) have
valves along the inner walls
the systolic pressure is the pressure at the height of a
only in the region of the capillaries that an exchange occur between
the plasma of the blood and the surrounding tissue fluid
pump for circulatory system
circulate blood to and from the heart
partterns of circulation
different pathways that vellses follow
help tissue fluid back to normal patterns of circulation
made in flat bones
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
- serum globulin- immulogical responses.
- help with fluids
- 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
smallest cells, clotting mechanism.
WBC granular leukocytes
- made in bone marrow.
- basophil, neutrophil, and eosinophil.
- Have a nucleus.
Protects body against infection
remove large particles like broken down tissue cells.
engolphing forign substances and make antibodies.
- substances (protien) stimulate organisms immune system to make antibody
- found in rbc
- produced by immune system that destroys or innactivats a particular antigen
- found in plasma
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
inflamation of the sac the heart sits in
layers of the heart
endocardium(inner), epicardium(outer layer), myocardium (middle)
blood from the body
bring blood to heart
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
carry blood away from the heart
layers of veins and arteries
tunica intama, media, anvatitia
the pressure within the vessels
squeezing of the heart
- is in radial bone by hand
- in neck
- in the head
- out of right ventricle (heart) into the lungs
- returned to heart via pulmonary veins
- drainage of gastrointestinal area going into portal vein into the liver.
- leave liver in a large hepatic vein.
- unique cuz of non functional systems
- no need for digestive and respiratory system
2 umbilical arteries and 1 umbilical vein make
the umbilical cord
hole in the heart that sends blood from the right to left atrium
short vessel that connects the pulmonary artery to the arota. bypassing lungs
functions of lymphatics
important role in circulation.
