Lesson 13 Flashcards
artery
blood vessel that carries blood away from the heart
coronary artery
the first branch of the aorta
dorsalis pedis artery
artery located at the ankle joint
dysphasia
impairment of speech and verbal comprehension
femoral artery
artery located in the groin area
fetal circulation
brings blood to the fetus
gangrene
death of body tissue due to insufficient blood supply
hemiplegia
paralysis of one side of the body
hypertension
abnormally high blood pressure
hypotension
reduced or abnormally low blood pressure
popliteal artery
artery located behind the knee
portal vein
major vein leading to the liver
pulse
a measurement of the number of times the heart beats per minute
radial artery
artery located at the wrist
tunica intima
the inner arterial layer
aneurysm
a widening or sac formed by dilation of a blood vessel
arterioles
small branches of an artery
tunica media
valves
veins
vessels that carry blood toward the heart
venules
small veins
aphasia
loss of ability to speak; may be accompanied by loss of verbal comprehension
arteriosclerosis
hardening of arteries, resulting in thickening of walls and loss of elasticity
athersclerosis
hardening of arteries due to deposits of fatlike material in the lining of the arteries
brachial artery
artery located at the crook of the elbow along the inner biceps muscle
capillaries
microscopic blood vessel that connects the aterioles to the venules
cardiopulminary circulation
the system of carrying blood from the heart to the lungs and back
carotid artery
artery that supplies blood to the neck and head
cerebral hemorrhage
bleeding from blood vessels in the brain
cerebral vascular accident
sudden interruption of blood flow to the brain; also called stroke
coronary circulation
brings blood from the aorta to the myocardium and back to the right atrium
diastolic blood pressure
pressure measured when the ventricles are relaxed
ductus arteriosus
fetal structure that permits blood to flow from the pulmonary artery to the aorta
ductus venosus
fetal structure that connects the umbilical vein to the inferior vena cava in the fetus; this vessel usually closes within 30 minutes after birth
foramen ovale
an opening in the septum between the right and left atria of the fetus
hemorrhoids
enlarged and varicose condition of the veins in the lower part of the anus or rectum and the tissues of the anus
hepatic vein
vein that drains blood from the liver into the inferior vena cava
hypoperfusion
inadequate flow of blood carrying oxygen to the organs and body systems; also known as shock
peripheral vascular disease
blockage of arteries usually in the legs
phlebitis
inflammation of a vein, with or without infection and thrombus formation
portal circulation
brings blood from the organs of digestion through the portal vein to the liver
pulse pressure
the difference between systolic and diastolic pressure
systemic circulation
circulation that takes blood from the heart to the tissues and cells of the body and back to the heart
systolic blood pressure
pressure measured at the moment of ventricle contraction
temporal artery
artery located slightly above the outer edge of the eye
transient ischemic attacks
temporary interruptions in blood flow to the brain
tunica adventitia
the outer layer of arterial walls
varicose veins
veins that have become abnormally dilated and tortuous due to interference with venous drainage or weakness of their walls
venipuncture
the method of drawing blood using a needle to access a vein for intravenous therapy, or a sampling of venous blood for testing
white-coat hypertension
increase in a patients blood pressure that occurs only when a medical professional takes the blood pressure
