capillary

open circulation
blood is equivalent to interstitial fluid; circulating is equal to extracellular; fluid is called hemolymph
pulmonary (circuit)
from right side of heart, through pulmonary arteries to LUNGS "blue blood" and then to pulmonary veins
hemoglobin
protein in red blood cells that carry oxygen and carbon dioxide
Purkinje fibers
specalized cells located in the walls of the ventricles; relay nerve impulses from the AV node to the ventricles causing them to contract

body

d. nodes
Phlebotomist, venipuncturist
nurse or technician who draws blood for lab tests, and/or starts IV's
 
means "cutting into vein"
collects from tissue spaces the fluid that is filtered out of the blood vessels and conveys it back to the vascular system.
lymphatic system
fenestrated capillaries
have numerous fenestrae (or pores) in the endothelial walls where the cytoplasm is absent
post cava
transports oxygen poor blood form the lower body to the heart
DOES THE SPLEEN CONNECT TO ANY OTHER ORGANS?
NO
Pulmonary Vessels
system that transports blood from the right ventricle to the lungs and back to the left atrium.
artery
a blood vessel that conveys blood from the heart to any part of the body.
vena cava
either of two large veins discharging blood into the right atrium of the heart, one
pulmonary circulation
the circulation of blood from the heart to the lungs for oxygenation and back to the heart.
ventricle
any of various hollow organs or parts in an animal body.
systemic (circuit)
from left side of heart, through aorta and arteries to BODY "red blood" and then to vena cava
RIGHT/LEFT VENTRICLE
inferior chambers in the heart - in the "V" of the heart

tunica externa
the outermost layer of a blood vessel, composed primarily of loose c.t.
left ventricle
pumps blood to the body through the aortic arch
WHAT IS ANOTHER ROLE OF THE TONSILLS?
FORMATION OF LYMPHATICS
The _____ _______ v.v. are the largest veins that drain the head and neck.
INTERNAL JUGULAR
white blood cell
any of various nearly colorless cells of the immune system that circulate mainly in the blood and lymph and participate in reactions to invading microorganisms or foreign particles, comprising the B cells, T cells, macrophages, monocytes, and granulocytes
sinoatrial node
small mass of tissue in the right atrium functioning as pacemaker of the heart
