Red=ARTERIES
Blue=VEINS
Circulatory System
Arteries:
- Thoracic aorta (VERY LARGE, from the heart around down the diaphragm, more on left side, kinda behind the lung)
- Brachiocephalic artery (branches into...)
- Right subclavian artery
- Left common carotid artery
- Right common carotid artery
- Left subclavian artery (goes off on its own and goes to left shoulder on its own)
Veins:
- Anterior vena cava
- Common trunk of internal mammary veins (may find, usually more obvious in cat that has had kittens)
- Left brachiocephalic vein
- Right brachiocephalic vein
There are 3 branches that empty into:
- Common trunk of costocervical and vertebral trunk vein (costocervical goes down into the spine)
- Subclavian vein
- External jugular vein (big)
- Internal jugular vein (joins the external, close to trachea)
Veins of head and neck:
- Transverse jugular vein
- Anterior facial vein
- Posterior facial vein
Vessels in brachial region:
- Left subclavian artery (both left and right easier to follow, becomes axillary artery as soon as it passes the 1st rib)
- Right subclavian artery
- Left subclavian vein (easier to follow)
- Right subclavian vein (both left and right becomes axillary artery as soon as it passes the 1st rib)
These all become...
- Axillary artery
- Axillary vein
Which branches into...
- ventral thoracic artery
- ventral thoracic vein
- subscapular artery
- subscapular vein
- brachial artery (main continuation of the axillary artery and vein)
- brachial vein (main continuation of the axillary artery and vein)
Find further down the front limb:
- Brachial artery
- Brachial vein
- Cephalic vein (we take blood from here, on top of forearm)
- Medial cubital vein (connects cephalic vein to brachial vein, just above the elbow bu basically on the medial side)
Inner thoracic wall:
- Azygous vein (runs along right side of aorta and empties into anterior vena cava)
- Intercostal arteries
- Intercostal veins
