Circulatory System Blood Vessels

What are superficial veins? Are there superficial arteries? What do the superficial veins drain into? What are the venous sinuses? WHere in the body can you find venous sinuses? What are the deep veins?

Superficial veins lie just beneath the skin and drain into deep veins. There are no superficial arteries.. Venous sinuses are spaces that collect the blood and return it to the regular veins. Deep veins travel with an artery.

What is the overall purpose of the systemic circulation? Name all of the parts of the heart and the major blood vessels associated with the heart that are involved in the systemic circulation.

The overall purpose of the systemic circulation is the general circulation of blood to the body as a whole. Left atrium of heart (oxygenated) --> L ventricle of heart --> through an arterial tree whose trunk is the aorta and whose finest branches are the arterioles --> capillary beds of the body --> venule --> systemic veins --> superior and inferior vena cava --> R atrium of heart

What is the overall purpose of the portal circulation? What two capillary beds does the hepatic portal vein connect? What three veins form the hepatic portal vein?

The purpose of the portal circulation allows the liver to monitor the substances absorbed in the GI tract before passing that blood into the general circulation.

What is the overall purpose of the pulmonary circulation? Name all of the parts of the heart and major blood vessels involved in the pulmonary circulation. The pulmonary arteries carry what type of blood (oxygenated or deoxygenated)? What type of blood do the pulmonary veins carry?

The purpose of the pulmonary circulation is to move blood through the heart. Right atrium of the heart--> right ventricle of the heart --> pulmonary trunk--> R and L pulmonary arteries --> lung capillary beds--> pulmonary veins --> 2 R or 2 L pulmonary veins--> L atrium of the heart The pulmonary arteries carry deoxygenated blood and the pulmonary veins carry oxygenated blood.

Trace a red blood cell's path from the right ulnar vein to the right radial artery. If the red blood cell passes through the heart name every chamber and valve it passes through. Also note right or left side for a blood vessel where appropriate. Try tracing a cell's path from the left posterior tibial vein to the common hepatic artery. For your third practice run try tracing a cell's path from the splenic vein to the left posterior cerebral artery.

right ulnar vein --> r brachial vein --> R axillary vein --> R subclavian vein --> R brachiocephalic vein --> superior vena cava --> R atrium of heart -->(tricuspid valve)--> R ventricle -->(pulmonary semilunar valve)--> pulmonary trunk --> R or L pulmonary artery ->->-> R or L lung capillary bed (oxygenation of blood) ->->-> 2R or 2L pulmonary vein ---> L atrium of heart --> (mitral valve) --> L ventricle of the heart --> (aortic semilunar valve) ---> ascending aorta --> arch of aorta --> brachocephalic trunk --> R subclavian artery --> R axillary artery --> R brachial artery --> R raial artery L posterior tibial vein --> L portal vein --> L femoral vein --> L external iliac vein --> L common iliac vein --> inferior vena cava --> through the heart, blood is oxygenated in the lungs --> ascending aorta --> arch of aorta --> thoracic aorta --> abdominal aorta --> celiac trunk --> common hepatic artery Splenic vein --> hepatic portal vein --> liver sinusoids (capillaries) ---> (through central veins of liver lobule) ->->-> hepatic veins --> inferior vena cava ->->-> through the heart blood is oxygenated in lungs ->->-> asceding aorta --> arch of aorta --> left subclavian artery --> left vertebral artery --> basular artery --> left posterior cerebral arter
