| Question | Answer |
|---|---|
| The ciculatory process that carries blood from the right ventricle of the heart to the lungs and back to the left atrium of the heart | pulmonary circulation |
| What type of blood is transported by the pulmonary circulation to the lungs | unoxygenated |
| What is the larger circulation? | systemic circulation |
| arteries | blood vessels that carry blood away from the heart |
| What blood vessel is close to every cell? | capillaries |
| veins | carry blood back to the heart |
| What are the 3 layers of a blood vessel? | tunica intima,tunica media, and the tunica adventitia |
| What is the main function of the tunica adventitia? | support and protection of blood vessels |
| resistance vessels | arterioles |
| conductance vessels | arteries |
| exchange vessels | capillaries |
| capacitance vessels | veins and venules |
| What three large arteies arise from the aotic arch? | brachiocephalic artery, left common carotid artery, left subclavian artery |
| What are the brances of the abdominal aorta? | celiac trunk, mesenteric arteries, renal arteries |
| What 3 smaller arteries make up the celiac trunk artery? | gastric artery, splenic, and hepatic |
| The hepatic artery supplies what organ(s)? | liver |
| The superior mesenteric artery supplies blood to what organ(s)? | most of the small intestines, and part of the large intestine |
| What is the largest vein in the body? | vena cava |
| What vein drains blood from the brain? | internal jugular vein |
| What is the longest vein in the body? | great saphenous veins |

| How many blood vessels are in the unbilicus? | 3 |
| This structure carries blood from the umbilical vein to inferior vena cava, allowing the blood to bypass the liver? | ductus venosus |
| What structure allows blood to go directly from the right atrium into the left atrium to bypass the pulmonary circulation? | foramen ovale |
| What structure allows blood in the pulmonary artery to go directly into the descending aorta and to bypass the pulmonary circulation? | ductus arteriosus |
| systolic pressure | the pressue at the peak of ventricular contraction |
| diastolic pressure | the pressure in the large arteries when the ventrricles of the heart are relaxing |
| Korotkoff sounds | sounds caused by the flow of blood through the brachial artery |
| What are the structures of the baroreceptor reflex? | receptors, sensory nerves, medulla oblongata, and motor nerves |
| What is missing in the process of the baroreceptor reflex? baroreceptors--sensory nerves(cranial nerves IX,X)--motor nerves | medulla oblongata |
