Circulation systemic veins superficial and deep Flashcards
Function of veins
Carry blood from tissues back toward right atrium of heart
What do veins carry
most carry deoxygenated blood, except for pulmonary veins
Function of arteries
Carry blood away from heart
Where does the external jugular vein receive blood from
cranium exterior
Where does the external jugular vein deliver blood
into the subclavian vein
Location of external jugular vein
above sterneocleidomastoid
What are the vertebral veins
formed from small veins from deep muscles in upper posterior neck unite
Path of vertebral veins
enters transverse foramen of C1, descends forming a dense plexus around vertebral artery in canal formed by transverse foramen, emerges at C6 and unites with subclavian vein
Function of internal jugular vein
collects blood from brain and superficial parts of face and neck
Path of internal jugular vein
begins at jugular foramen at base of skull runs near common carotid artery and vagus nerve, ending at the root of neck
Path of subclavian veins
begins at outer border of first rib and ends at medial border of anterior scalene
size of subclavian veins
diameter of smallest finger
What veins does the subclavian vein unite with
internal jugular vein to form brachiocephalic vein
Path of brachiocephalic veins
level of sternoclavicular joint, at thoractic cavity and ends very quickly
What does the brachiocephalic vein unite with
internal jugular vein and subclavian vein
Which brachiocephalic vein is longer
left side (due to superior vena cava)
Location of superior vena cava
posterior to junction of 1st costal cartilage with manubrium, in right anteriorsuperior mediastinum
what does the superior vena cava unite with
subclavian and brachiocephalic veins
Function of superior vena cava
delivers deoxygenated blood from upper part of body to right atrium of heart
Size of superior vena cava
24mm diameter and short
What is a venae comitans
accompanying vein usually paired, veins lying on sides of an artery in a sheath of fascia
Function of venae comitans
drain lower regions of upper, lower limbs aiding venous return
What is the path of axillary vein
begins at the lower margin of teres major, continuation of brachial veins and ends at the lateral margin of first rib
