Cardiovascular System 2 - The Vessels Flashcards
What are the 3 main branches off the ascending aorta
Brachiocephalic trunk, left common carotid artery and left subclavian artery
What 2 branches does the brachiocephalic trunk split into
Right subclavian artery and right common carotid artery
What do the common carotid arteries supply
The head and neck
What do the subclavian arteries supply
The upper limbs
Describe what the subclavian artery splits into
Subclavian; axillary; brachial and profunda brachii
What are the 2 terminal branches that the brachial artery branches into
Radial artery (lateral to forearm) and ulnar artery (medial to forearm)
What arteries supply the hands and fingers
Deep and superficial palmar arches and digital arteries
What are the 2 superficial veins that drain the upper limbs
Cephalic vein (lateral side) and basilic vein (medial side)
What vein do the 2 superficial upper limb veins communicate through
Median cubital vein
Describe the pathway of deep veins in the upper limbs
Radial and ulnar veins; brachial vein; axillary vein; subclavian vein
What are the radial, ulnar and brachial veins classed as collectively
Venae Comitantes
What do the common carotid arteries split into
External and internal carotid arteries
What does the external carotid artery supply
Neck, face and scalp
What does the internal carotid artery supply
The brain
What artery is formed through the uniting of 2 vertebral arteries, and what does it supply
The basilar artery and it supplies the brain
Name 4 branches off the external carotid artery
Facial, posterior occipital, maxillary and superficial temporal
What vein does blood from the brain drain into
Internal jugular vein
What vein does blood from the face and scalp drain into
External jugular vein
What vein is formed when the internal jugular vein and subclavian vein unite
Brachiocephalic vein
What does the thoracic artery supply blood to
Oesophagus, pericardium, bronchi, thoracic wall and diaphragm
What specific arteries supply the thoracic wall with blood
Intercostal arteries
What veins does blood from the thoracic wall drain to
Azygos veins and straight into the superior vena cava
What artery branch supplies the foregut
Coeliac trunk/axis
What artery branch supplies the midgut
Superior mesenteric artery
What artery branch supplies the hindgut
Inferior mesenteric artery
What are the 3 lateral branches of the abdominal aorta
Suprarenal, renal and gonadal (ovarian and testicular)
What is the posterolateral branch of the abdominal aorta and what does it supply
Lumbar arteries and the body wall
What does the abdominal aorta bifucate into
Common iliacs; further to external and internal iliacs
What do the external iliacs supply
The lower limbs
What do the internal iliacs supply
The pelvic organs
What blood vessel do the abdominal veins integrate to
The inferior vena cava
Describe the pathway of the hepatic portal system veins (pre liver)
Inferior mesenteric vein to splenic vein; splenic vein and superior mesenteric vein combine to form hepatic vein and enter liver
Describe the pathway of the hepatic portal system veins (post liver)
Second capillary bed in liver to hepatic veins then enter inferior vena cava
What does the external iliac artery branch into
Femoral artery and profunda fermoris artery
What does the femoral artery turn into and where
It changes to the popliteal artery behind the knee cap
What does the popliteal artery branch into
Anterior and posterior tibial arteries
Describe the pathway of the anterior tibial artery
Down the front of the leg to the foot; becomes the dorsalis pedis
Describe the pathway of the posterior tibial artery
Down the back of the leg to the foot; branches into medial and lateral plantar arteries
Describe the pathway of the lower limbs deep veins
Anterior and posterior tibial veins; popliteal vein; femoral vein; external iliac vein
What superficial vein empties into the femoral vein
Great (long) saphenous vein
What superficial vein empties into the popliteal vein
Short saphenous vein
