Transcript of Cardiovascular System

introduction The Cardiovascular System is a vast
channel through which large quantities
of blood flow to necessary locations. blood types Three major arteries branch off from the aorta,
which is the largest artery in the body. The brachiocephalic
artery, left common carotid artery, and the left subclavian
artery blood flow to the head blood flow to the leg blood flow to the arm general information aorta brachiocephalic artery external carotid artery superficial temporal artery Blood flow to the head
is essential not only to fully
distribute oxygen to the entire
body, but also to allow the
mind to function at full potential. Blood flow to the leg
allows us to participate
in daily activities such as
walking and swimming,
and even rolling over
in bed. abdominal aorta common iliac artery external iliac artery femoral artery popliteal artery posterior tibial artery Blood flow to the arm
is necessary as well in order
to pick up a fork, read a book,
and write an essay. Without
blood flow to the arm, it would
be difficult to carry out daily tasks. aorta brachiocephalic artery axillary artery brachial artery radial artery
The cardiovascular system is a vast channel. The only way such a great mechanism could function is through all the arteries and veins. Veins and arteries compliment one another in deliverying and collecting blood. If one vein or artery does
not function correctly, major
damadge could be caused. Some
examples are clogged arteries,
and enlarged heart, or even high
blood pressure. cARDIOVASCULAR SYSTEM Blood is categorized by the types
of antibodies and antigens Antigen A and Antigen B
determine which blood is which Antigen A - Type A Antigen B - Type B Both Antigen A & B - Type AB Neither A nor B - Type O The main purpose of blood typing
is to perform a healthy blood
transfusion. If a healthy one is not
performed, the body will reject the
blood and death could be a result. Antibodies determine
which blood will be
accepted and rejected
in the body Anti B - Type A Anti A - Type B Neither Anti A nor B - Type AB Both Anti A and Anti B - Type O If any of the Antigen D and
other Rh factors are present,
the blood is Rh+. If red blood
cells lack the Rh antigens, the
blood is called Rh- blood structure plasma, which accounts for about 56% of a blood cell, is the clear liquid portion of the blood, which is made up of about 92% water, and the rest
consists of organic and inorganic
biochemicals Red blood cells have a small
opening in the middle in order
to transport oxygen more easily Red blood cells lack a nuclei
and mitochondria, so they can
not divide or synthesize mRNA, and only produce ATP through
glycolosis. With time, red blood cells
become less and less active,
and in return become more
rigid. When the blood cells
become too rigid they are
removed by the liver and spleen common carotid artery medial plantar artery right subclavian artery principal artery of thumb
