| Question | Answer |
|---|---|
| Arteries | carry blood away from the heart, oxygenated blood, blood from arteries go into arterioles |
| Arterioles | smallest arteries; blood from arteries goes into them |
| Capillaries | smalles of vessels; exchange oxygen and carbon dioxide |
| Veins | carry blood to the heart; deoxygenated blod |
| Vennules | smallest veins |
| Capillaries | smallest of vessels; exchange blood from blood and body cells and exhange blood and air in the lung tissue; this capillary exchange is going to exchange oxygen and carbon dioxide |
| Exception | respiratory system- pulmonary arteries carry deoxygenated blood; pulmonary veins carry oxygenated blood |
| Pulmonary Circuit | eliminates CO2 and replenishes O2 |
| Pulmonary Vessels | carry blood to and from the lungs |
| Systemic Circuit | supplies nutrients and oxygen to all the body tissue and carries wastes |
| Vasodilation | vessel increases in diameter; blood flow increases |
| Vasoconstriction | vessel decreases in diameter; blood flow decreases, blood pressure increases |
| Aneurysm | a sac or a bulged-out section of an artery or vein due to localized weakness; can rupture anytime; will rupture for sure after so big; most times found by accident |
| Bleeding from a Large Artery | blood flows in spurts |
| Anastomosis | communication between two vessels |
| Anastomosis | Circle of Willis, Volar Arch |
| Circle of Willis | example of an anastomosis of an artery |
| Osmotic Pressure | maintained in the capillaries by proteins |
| Diffusion | the process involved in capillary exchange; vennules or arterioles to the capillary |
| Venous Return | in veins of the legs is increased by contractions of the skeletal muscles; veins have valves and that's what helps with this |
| Venous Sinuses | Coronary Sinus |
| Venous Sinuses | spaces filled with blood; channels which lack normal vein structure that pull or collect deoxygenated blood in various parts of the body; found in different places |
| Vessels | (arteries and veins) contain three layers |
| Tunica interna | the innermost layer of the blood vessel; AKA endothelium |
| Tunica media | the middle and thickest layer; smooth muscle |
| Tunica externa | AKA tunica and ventitia; external outer layer; connective tissue |
| Aorta | largest in the body |
| Coronary Arteries | branches of the ascending aorta that supply the heart muscle with oxygen-rich blood |
| Coronary Sinus | (vein) receive blood from the veins of the heart wall |
| Common Carotid Arteries | carry oxygenated blood away from the heart to the neck and head and brain |
| Subclavians | main arteries of the arms; begin at the area of the collarbone |
| Brachial Artery | used to determine blood pressure |
| Radial Artery | thumb side of the lower arm; used to find pulse |
| Renal Artery | one for each kidney; supply the kidney with blood |
| Internal Iliac Artery | supplies structures and organs in the pelvic cavity with blood |
| Superior Mesenteric Artery | supplies the small intestines and some of the large intestines with blood |
| Femoral Artery | the large artery of the upper leg (thigh) |
| Two Largest Veins | inferior vena cava, superior vena cava |
| Inferior Vena Cava | drains blood from the lower part of the body into the right atrium |
| Superior Vena Cava | drains blood from the upper part of the body into the right atrium |
| Median Cubital | to draw blood (phlebotomy); antecubital space |
| Brachiocephalic | right and left; forms from the subclavian and jugular veins (where they meet) |
| Jugular | runs in correspondence with the carotid arteries; drains blood from the head and the neck |
| Hepatic | drains blood from the liver |
| Saphenous (great saphenous) | in the leg; largest and longest vein in the body; carries deoxygenated blood from the foot to the thigh |
| Sinusoids | an enlarged capillary channel that allows liver cells to have close contact with the blood; help the liver filter blood |
| Kidneys | don't have veins that drain into the portal system in order to help the liver; work on their own to detoxify the blood. Not part of the liver system. |
| Liver | works as its own little filtering system, so the blood is not as toxic as it was before it went into the ______; does the majority of the work |
