1

last and longest division of the largest artery off the aortic arch. Blood is flowing downward. It passes through the two divisions:1. Thoracic aorta2. Abdominal aorta

Descending aorta

2

What are the last two branches of the Abdominal aorta that terminates the descending aorta?

right and left common iliac arteries

3

where are the right and left common iliac arteries located?

located at the largest and most superior segment of the hip bone (ilium)

4

How many sets of iliac arteries are there?

three (3) sets

5

terminal branches of the descending aorta which divides into Internal & External iliac arteries

Common iliac artery

6

feeds and embalms the gluteal region

Internal iliac artery

7

(toward the outside) will continue as the femoral artery; lies medial

External iliac artery

8

What are types/ parts of lower extremities

thigh, knee, leg, foot

9

(hip & knee) medial boundary- the adductor longus muscle and where the femoral artery ends

Femoral- thigh region

10

the femoral artery continues as what?

popliteal artery (behind the knee) posterior to the knee

11

knee to ankle

Leg Region

12

The popliteal artery divides into what?

Anterior tibial arteryDorsalis pedisPosterior tibial artery

13

(in front of the tibia or shin bone) the artery comes from behind the knee and crosses in front of the shin bone or tibia. At the level of the ankle

Anterior tibial artery

14

The anterior tibial artery continues as what?

Dorsalis pedis

15

feeds blood to the toenail surface of the foot

Dorsalis pedis

16

(behind the tibia or shin bone) last artery and feeds the sole of the foot

Posterior tibial artery

17

the diaphragm divides serving as what?

a boundary line for the descending aorta between the thoracic and abdominal cavities

18

leaving the arch of aorta, continues as the descending aorta in the thoracic cavity called?

thoracic aorta

19

What are the two branches off the thoracic aorta

1. Parietal branches2. Visceral branches

20

feeds the walls making up the thoracic cavity

Parietal branches

21

What are the branches off the parietal branch

1. Intercostal arteries2. Subcostal arteries3. Superior phrenic arteries

22

feed the spaces between the ribs 8 or 9 pair

Intercostal arteries

23

two (2) feed the spaces beneath the ribs, but above the diaphragm

Subcostal arteries

24

two (2) Left & Right feed the superior surface of the phrenic muscle or diaphragm

Superior phrenic arteries

25

feeds the viscera or organs within the thoracic cavity

Visceral Branches

26

What are the branches off the Visceral branch

1. Bronchial arteries2. Pericardial arteries3. Esophageal arteries

27

feed the bronchi (passageway between the windpipe and lungs) trachea

Bronchial arteries

28

feed the pericardium (sack surrounding the heart)

Pericardial arteries

29

feed that portion of the esophagus located in the thoracic cavity (esophagus- the muscular tube that conveys food from the throat to the stomach)

Esophageal arteries

30

branches that come off the abdominal aorta 3 sets are classifies according to what they feed

Descending abdominal aorta

31

What are the 3 sets of branches off the descending abdominal aorta

Unpaired visceral branchesPaired visceral branchesParietal branches

32

feed unpaired or single organs within the abdominal cavity. All branches that come off of the anterior (front) of the aorta feed the unpaired organs and are classified as unpaired visceral branches

Unpaired visceral branches

33

feed paired organs, organs that occur in pairs located with or originate in the abdominal cavity. All branches that come off of the lateral sides of the aorta feed paired organs located in or originating in the abdominal cavity are classified as paired visceral branches

Paired visceral branches

34

feed the walls that make up the abdominal cavity. All branches that come off the posterior (bottom) of the aorta feed the walls of the abdominal cavity are classified as parietal branches

Parietal branches

35

What are the branches of the parietal branches off the Abdominal Aorta (Posterior)

1. Inferior Phrenic Arteries2. Lumbar Arteries3. Middle sacral arteries

36

two (2) Left and RIght most superior are the Inferior Phrenic Arteries of the parietal branch off the abdominal aorta- feed the inferior, or under the surface, of the Phrenic muscle or diaphragm

Inferior Phrenic Arteries

37

four pair- feed the lumbar or lower back region

Lumbar arteries

38

most inferior single unpaired parietal branch off the abdominal aorta- feed the sacrum and coccys and rectum

Middle sacral arteries
