Major Veins of the Systemic CirculationFigure 19.20bVeins of the Head and NeckDural SinusesSuperior and inferior sagittal sinuses
Straight sinus
Transverse sinuses
Sigmoid sinus

External jugular veins
Vertebral veinsVeins of the Upper LimbsDeep Veins - follow the paths of companion arteries- have the same names as the companion arteries
Superficial veins - visible beneath the skin- Cephalic vein- Basilic vein- Median cubital vein- Median vein of the forearm
Veins of the Right LimbFigure 19.21aAntecubital FossaForm anastomese frequently
Median cubital vein - used to obtain blood or administer IV fluidsFigure 19.22

Disorders of the Blood VesselsAneurysm
Deep vein thrombosis of the lower limb
Venous disease
Microangiopathy of diabetes
Arteriovenous malformationBlood Vessels Throughout LifeFetal CirculationAll major vessels in place by month three of development
Differences between fetal and postnatal circulation include:- fetus must supply blood to the placenta- very little blood is sent through the pulmonary circuitVessels to and from the PlacentaUmbilical vessels run in the umbilical cord- paired umbilical arteries- unpaired umbilical vein
Fetal vessels and structures- Ductus venosus - Ligamentum teres- Ligamentum venosum - Medial umbilical ligamentsFigure 19.28a
Fetal CirculationShunts Away from the Pulmonary Circuit- Foramen ovale- Ductus arteriosus
Blood Vessels in AdulthoodAtherosclerosis begins in youth- consequences evident in middle to old age
Males- more atherosclerosis than females between ages 45 65
Females- experience heart disease and atherosclerosis later in life
