Exam 4

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?

Ductos Arteriosus and Foramen ovale

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

Umbilical artery

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
E)Ductus arterious

Foramen ovale

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

Umbilical vein

Bypass the fetal lungs by shunting blood from pulmonary trunk to the aorta?
A)Umbilical vein
B)Foramen ovale
C)Ductus venosus
D)Umbilical artery
E)Ductus arterious

Ductus arterious
