Anat-Arteries

QuestionAnswer
blood "structure" liquid connective tissue with liquid matrix between the cells consisting mostly of water with dissolved gases, sugars, amino acids, etc.
hemopoiesis process of the formation of blood cells and matrix
hemopoiesis location tissue found in the marrow cavity of spongy bone
spongy bone structure/location has hollow cavities separated by bone plates; found deep in bone
types of tissue in spongy bone red and yellow bone marrow
red bone marrow function actually produces blood tissue
yellow bone marrow adipose (fatty) tissue formed when red bone marrow degenerates
erythrocytes red blood cells, contain hemoglobin with bound oxygen
two types of white blood cells lymphocytes and neutrophils
white blood cell structure/function visible nucleus, larger than RBC's, immune system function
types of arteries elastic, muscular, arterioles, (capillaries)
elastic artery structure largest, diameter of 1-2cm, has mostly layers of elastic connective tissue and some smooth muscle, branch into muscular arteries
muscular artery structure 1cm-3mm in diameter, have fewer layers of elastic connective tissue and more smooth muscle, branch to form arterioles
arterioles structure less than 3mm in diameter, branch to form capillaries
capillaries structure/function smallest blood vessel (diameter is almost as small as that of a RBC), site of gas exchange between hemoglobin (RBC) and interstitial fluid
blood flow through capillaries blood comes in from arterioles and leaves into the venous system
aneurysm weak point in an artery of wall of the heart that balloons outwards and may rupture (hemorrhage) due to the high pressure that blood is pumped under
aorta function blood vessel from which all arteries are derived either directly or indirectly; supplies the entire body with oxygenated blood
aorta parts ascending aorta, aortic arch, descending thoracic aorta, descending abdominal aorta
branches of the ascending aorta coronary arteries
coronary arteries function supply the heart with oxygenated blood (heart is the first organ to receive oxygenated blood)
branches of the aortic arch brachiocephalic trunk, left common carotid, left subclavian
branches of the brachiocephalic trunk right common carotid and right subclavian
carotid arteries location go up the left and right sides of the neck
subclavian arteries location go towards the left and right shoulders; posterior to the clavicle
aortic arch branches function supply the head, neck, shoulders, arms, etc
branches of the common carotid arteries internal carotid arteries and external carotid arteries
internal carotid arteries location begin a little bit below the corner of the mandible and go into the skull through the carotid canal (supply the brain)
external carotid arteries location begin a little bit below the corner of the mandible and branch along the external surfaces of the head and face
branches of the subclavian arteries left and right vertebral arteries (axillary and brachial artery)
vertebral arteries location pass through the transverse foramen of the cervical vertebrae and into the skull through the foramen magnum (supply the brain)
three major arteries of the upper arm and shoulder subclavian, axillary, brachial
branching pattern of the upper arm arteries no real branching pattern-- names refer to a segment of what is really one blood vessel, depending on the region it passes through
axillary artery location within the axillary (armpit) region
brachial artery location within the brachium (arm)
branches of the brachial artery ulnar artery and radial artery (branches after the elbow)
branches of the descending abdominal aorta (GI tract) celiac trunk, superior mesenteric artery, inferior mesenteric artery, left and right renal arteries (branches at the top of the pelvic cavity and travels into each lower limb)
descending abdominal aorta function supplies virtually all organs of the abdominal cavity
celiac trunk function carries oxygenated blood to the liver, stomach, spleen, pancreas, and first part of the small intestine
superior mesenteric artery function sends blood to the rest of the small intestine and the first half of the large intestine
inferior mesenteric artery function carries blood to the last half of the large intestine
left and right renal arteries function carry blood to the kidneys
branches of the descending abdominal aorta (pelvis and lower limb) common iliac arteries (one for each limb)
branches of the common iliac artery external and internal iliac arteries
branches of the external iliac artery femoral and popliteal artery
branches of the popliteal artery anterior and posterior tibial arteries
internal iliac artery location goes down into the pelvic cavity
branching pattern of the external iliac arteries all one blood vessel (named for the area it passes) until it splits after the knee into the anterior and posterior tibial arteries
