WHY ARE THE WALLS OF ARTERIES PROPERTIONATELY THICKER THAN THOSE OF THE CORRESPONDING VEINS?
Because the blood is pumped directly into arteries so there is more pressure on the arteries
THE ARTERIAL SYSTEM HAS ONE OF THESE; THE VENOUS SYSTEM HAS TWO
BRACHIOCEPHALIC
THESE ARTERIES SUPPLY THE MYOCARDIUM
CORONARY
THE MORE ANTERIOR ARTERY PAIR SERVING THE BRAIN
EXTERNAL CAROTID, INTERNAL CAROTID
LONGEST VEIN IN THE BODY
GREAT SAPHENOUS
ARTERY ON THE DORSUM OF THE FOOT CHECKED AFTER LEG SURGERY
DORSALIS PEDIS
SERVES THE POSTERIOR THIGH
FEMORAL
SUPPLIES THE DIAPHRAGM
PHRENIC
FORMED BY THE UNION OF THE RADIAL AND ULNAR VEINS
BRACHIAL
TWO SUPERFICIAL VEINS OF THE ARM
BASILIC, CEPHALIC
ARTERY SERVING THE KIDNEY
RENAL
ARTERY THAT SUPPLIES THE DISTAL HALF OF THE LARGE INTESTINE
INFERIOR MESENTERIC
DRAINS THE PELVIC ORGANS AND LOWER LIMBS
COMMON ILIAC ?
MAJOR ARTERY SERVING THE ARM
SUBCLAVIAN
SUPPLIES MOST OF THE SMALL INTESTINE
SUPERIOR MESENTERIC
AN ARTERIAL TRUNK THAT HAS THREE MAJOR BRANCHES, WHICH RUN TO THE LIVER, SPLEEN, AND STOMACH
CELIAC TRUNK
MAJOR ARTERY SERVING THE SKIN AND SCALP OF THE HEAD.
COMMON CAROTID
JOIN TO FORM THE INFERIOR VENA CAVA
COMMON ILIAC
ARTERY GENERALLY USED TO TAKE THE PULSE AT THE WRIST
RADIAL
THREE VEINS SERVING THE LEG
ANTERIOR TIBIAL, FIBULAR, POSTERIOR TIBIAL
PULMONARY CIRCULATIONS...
TRACE THE PATHWAY OF A CARBON DIOXIDE GAS MOLECULE IN THE BLOOD FROM THE INFERIOR VENA CAVA UNTIL IT LEAVES THE BLOODSTREAM. NAME ALL STRUCTURES (VESSELS, HEART CHAMBERS, AND OTHERS) PASSED THROUGH EN ROUTE.
RIGHT ATRIUM -> RIGHT VENTRICLE -> PULMONARY TRUNK -> RIGHT OR LEFT PULMONARY ARTERY -> LOBAR ARTERY -> PULMONARY CAPILLARY BEDS IN LUNGS -> AIR SACS OF LUNGS.
Trace pathway of oxygen gas molecule from an alveolus of the lung to the right atrium of the heart
alveolar capillary walls; pulmonary vein; left atrium; left ventricle; aorta; systemic arteries; capillary beds of tissues; systemic veins; superior or inferior vena cava
Branches of the internal carotid and vertebral ateries cooperate to form a ring of blood vessels encircling the pituitary gland, at the base of the brain. What name is given to this communication network?
CIRCLE OF WILLIS
WHAT IS THE FUNCTION OF THE CEREBRAL ARTERIAL CIRCLE (CIRCLE OF WILLIS)?
PROVIDES ALTERNATE PATHWAYS FOR BLOOD TO REACH BRAIN TISSUE IN THE CASE OF IMPAIRED BLOOD FLOW IN THIS SYSTEM
THE ANTERIOR AND MIDDLE CEREBRAL ARTERIES ARISE FROM THE ____ ARTERY
INTERNAL CAROTID
??
WHAT PORTION OF THE BRAIN IS SERVED BY THE ANTERIOR AND MIDDLE CEREBRAL ARTERIES?
CEREBRUM
TRACE THE PATHWAY OF A DROP OF BLOOD FROM THE AORTA TO THE LEFT OCCIPITAL LOBE OF THE BRAIN, NOTING ALL STRUCTURES THROUGH WHICH IT FLOWS?
aorta---->subclavian artery-----> vertebral artery-------> basilar artery-----> posterior cerebral artery----->left occipital lobe
What do the pulmonary arteries carry and to where?
oxygen-poor blood to the lungs
What do the pulmonary veins carry and to where?
oxygen-rich blood to the left heart
What do most arteries carry?
oxygen-rich blood
What do most veins carry?
oxygen-poor blood
What is the exception to the fact that most arteries carry oxygen rich blood?
the pulmonary arteries
What is the exception to the fact that most veins carry oxygen poor blood?
the pulmonary veins
Most arteries of the adult body carry oxyen-richblood, and the veins carry oxygen-depleted, carbon dioxide-richblood. What is different about the pulmonary arteries and veins?
The pulmonary arteries carry oxygen-poor blood to the lungs, the pulmonary veins carry oxygen-rich blood from the lungs to the heart
Why is the hepatic portal blood carried to the liver b4 it enters the systemic circulation?
BC it is rich in nutrients and the liver is responsible for maintaining proper blood concentrations of glucose, proteins, etc. and its phagocytes rid the body of debris
What is the special vessel called where the unpaired veins draining the digestive tract organs empty and carry blood to the liver b4 it enters the systemic venous system?
blood drained from the digestive viscera
The failure of two of the fetal bypass structure to become obliterated after birth can cause congenital heart disease in which the youngster would have improperly oxygenated blood which are the two?

Which carries oxygen-poor blood from the fetus to the placenta?
A)Umbilical vein
B)Foramen ovale
C)Ductus venosus
D)Umbilical artery
E)Ductus arterious

Shunts blood through the fetal liver bypassing the bulk of its tissue?
A)Umbilical vein
B)Foramen ovale
C)Ductus venosus
D)Umbilical artery
E)Ductus arterious
Ductus venosus
Bypass the lungs by shunting blood from the right atrium to the left atrium?
A)Umbilical vein
B)Foramen ovale
C)Ductus venosus
D)Umbilical artery

Carries oxygen-rich blood from the placenta to fetus?
A)Umbilical vein
B)Foramen ovale

A)Umbilical vein
B)Foramen ovale
C)Ductus venosus
D)Umbilical artery
E)Ductus arterious
Ductus arterious
