3 sections of the aorta and corresponding branches

Answer 1

1. ASCENDING AORTA
   - R+L coronary arteries
2. AORTIC ARCH: arches posteriorly and left
   - BRACHIOCEPHALIC ARTERY
   - L COMMON CAROTID ARTERY
   - L SUBCLAVIAN ARTERY
3. DESCENDING AORTA
   - THORACIC AORTA: portion in thorax
   - ABDOMINAL AORTA: inferior to diaphragm. Ends as two common iliac arteries

Question 2

2

Answer 2

RIGHT
- ascending aorta -> R coronary artery
- aortic arch
- brachiocephalic artery
-> R common carotid -> R internal/external carotid
-> R subclavian artery
-> R vertebral artery
-> axillary artery -> brachial artery

LEFT
- ascending aorta -> L coronary artery
- aortic arch
- L common carotid artery -> L internal/external carotid arteries
- L subclavian artery
-> L R vertebral artery
-> L axillary artery -> brachial artery

Question 3

arteries below abdominal aorta

Answer 3

• L and R common iliac arteries
  
  • branch: internal iliac artery
• external iliac artery
  
  • branch: deep femoral arteries
• femoral artery

Question 4

names of arteries of upper and mid body and which structures they support

Answer 4

External carotid: head, face and neck
Internal carotid: brain
Subclavian + Axillary: shoulder, chest and back
Brachial: arm
Common Hepatic: liver
Renal: kidneys

Question 5

names of arteries of lower body and which structures they support

Answer 5

Internal iliac: pelvis, pelvic organs, external genitalia and hip
External iliac: lower lim finish card

Question 6

Major veins

Answer 6

• CORONRY SINUS (heart)
• SUPERIOR VENA CAVA
• INFERIOR VENA CAVA

Question 7

3 types of veins

Answer 7

1. SUPERFICIAL
2. DEEP
3. SINUSES (cranial cavity and heart)

Question 8

deep veins

Answer 8

follow same names as arteries
tend to be paired

Question 9

matching veins to carotid arteries

Answer 9

internal and external JUGULAR

Question 10

explain bloodflow from superior vena cava

Answer 10

• super vena cava
  (on both sides)
  
  • brachiocephalic vein
    
    • branch: CEPHALIC
    • axillary
    • branch: brachial veinS
    • median CUBITAL

on left side:
- L brachiocephalic vein
- internal and external JUGULAR veins come before axillary

Question 11

explain bloodflow from inferior vena cava

Answer 11

• inferior vena cava
  
  • hepatic vein
  • hepatic portal
• split into L+R common iliac vein
  
  • internal iliac vein
• external iliac vein
  
  • branch: GREAT SAPHENOUS (will someones be cut for CBS)
• femoral vein
