Question | Answer |
What is the size & function of Arteries? | Large-medium-small; take blood away from heart |
What is the size & function of Arterioles? | Small-microscopic; take blood away from heart - change blood flow by change in diameter |
What is the size & function of Capillaries? | Microscopic; gas exchange (O2/CO2) - nutrient/waste exchange |
What is the size & function of Venules? | Microscopic-small; return blood toward heart |
What is the size & function of Veins? | Small-medium-large; return blood toward heart |
What are the components of the Hepatic Portal System? | Hepatic Portal V. < Liver < deO2 blood < Hepatic V's < Inferior vena cava < Heart < Abdominal A. < Proper hepatic A. < O2 blood < back to Liver where Hepatic Portal V. joins |
In the Systemic Circulation, which large vessels are found in the upper body? | Descending Aorta, Thoracic Aorta, Abdominal Aorta |
In the Systemic Circulation, which large vessels are found in the upper extremities? | Subclavian A. < Axillary A. < Brachial A. < bifurcates into Radial & Ulnar A's. |
In the Systemic Circulation, which large vessel is found in the lower body? | Abdominal Aorta |
In the Systemic Circulation, which large vessels are found in the lower extremities? | Abd. A. < bifurcates into R/L Common Iliac A. < bifurcates into Int. Ext. Iliac A's.; Ext. Iliac < Femoral A. < Popliteal A. < bifurcates into Ant. & Post. Tibial A.; Ant. Tib. A. < Dorsalis Pedis A. |
What is the pathway of the lower extremity veins? | Ant. & Post. Tibial V. merge to form Popliteal V. < Great Saphenous V. terminates in Femoral V. Cont as Ext. Iliac V. merges w/ Int. Iliac V < Common Iliac V then merges into IVC |
Arterial flow TO the organs via: | Abdomial Aorta, Hepatic A., R&L Renal A., Splenic A. |
Venous return FROM the organs via: | IVC, Hepatic V., R&L Renal V., Hepatic Portal V., Splenic A. |
What affects blood pressure? | Anything that affects HR or SV or Resistance will affect CO and ultimately BP |
