CROSS-SECTIONAL VIEWS OF AN ARTERY AND OF A VEIN ARE SHOWN HERE. IDENTIFY EACH; ON THE LINES TO THE SIDES, NOTE THE STRUCTURAL DETAILS THAT ENABLED YOU TO MAKE THESE IDENTIFICATIONS:

STRUCTURAL DETAILS:
ARTERY: ROUND AND THICK
VEIN: THIN AND SQUIGGLY
2
CHARACTERISTICS OF TUNICA INTIMA
INNERMOST TUNIC, THIN TUNIC OF CAPILLARIES
3
CHARACTERISTICS OF TUNICA MEDIA
ESPECIALLY THICK IN ELASTIC ARTERIES, CONTAINS SMOOTH MUSCLE AND ELASTIN 4
CHARACTERISTICS OF TUNICA EXTERNA
MOST SUPERFICIAL TUNIC, HAS A SMOOTH SURFACE TO DECREASE RESISTANCE TO BLOOD FLOW 5
WHY ARE VALVES PRESENT IN VEINS BUT NOT IN ARTERIES?
Veins need valves to create pressure to pump the blood to the heart. Blood flows away from the heart and, therefore, the pressure is not required. Helps against gravity. 6
NAME TWO EVENTS OCCURING WITHIN THE BODY THAT AID IN VENOUS RETURN. 1. Respiratory "Pump". Pressure changes that occur in the thorax during breathing. 2. Muscular "Pump". Contraction and Relaxation of skeletal muscles surrounding the veins 7

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 8
THE ARTERIAL SYSTEM HAS ONE OF THESE; THE VENOUS SYSTEM HAS TWO BRACHIOCEPHALIC
9
THESE ARTERIES SUPPLY THE MYOCARDIUM
CORONARY
10
TWO PAIRED ARTERIES SERVING THE BRAIN
EXTERNAL CAROTID, INTERNAL CAROTID
11
LONGEST VEIN IN THE LOWER LIMB
GREAT SAPHENOUS
12
ARTERY ON THE DORSUM OF THE FOOT CHECKED AFTER LEG SURGERY
DORSALIS PEDIS
13
SERVES THE POSTERIOR THIGH
FEMORAL
14
Ok, so you’re using my notecards which is great. I am glad I could help you out cause I wish I had someone to help me out when I took this course. I know Anatomy is super hard. I only ask that if you find these notecards helpful, you join Easy Notecards and create at least one notecard set to help others out. It can be for any subject or class. Thanks and don’t forget to rate my helpfulness! 15

SUPPLIES THE DIAPHRAGM

27
MAJOR ARTERY SERVING THE TISSUES EXTERNAL TO THE SKULL
COMMON CAROTID
28
THREE VEINS SERVING THE LEG
ANTERIOR TIBIAL, FIBULAR, POSTERIOR TIBIAL
29
ARTERY GENERALLY USED TO TAKE THE PULSE AT THE WRIST
RADIAL
30
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. 31
THE ANTERIOR AND MIDDLE CEREBRAL ARTERIES ARISE FROM THE __1__ ARTERY. THEY SERVE THE __2__ OF THE BRAIN. 1. INTERNAL CAROTID
2 CEREBRUM
32
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? subclavian artery, vertebral artery, basilar artery, posterior cerebral artery 33
