Anat-Arteries
| Question | Answer |
|---|---|
| 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 |
