Pulmonary Circulation  oxygenated blood to left atrium via pulmonary veins oxygenate blood and remove carbon dioxide pulmonary circulation origination  right ventricle via pulmonary artery Systemic Circulation  starts with aorta receiving output from LV Systemic circulation output with exercise  varies greatly to skin and skeletal muscles Systemic vs pulmonary pressure  systemic 5-10x higher than pulmonary Blood flow with heavy exercise  Significantly increase blood...

Bio208 Anatomy Blood Vessels and Circulation (Gardner, CSULB)Heart pumps blood by increasing local pressure As blood travels through circulatory system, it encounters: friction Blood Vessel Types • Arteries- Carry Blood Away From Heart • Arterioles- Are Smallest Branches Of Arteries • Capillaries- Are Smallest Blood Vessels (Location Of Exchange Between Blood & Interstitial Fluid) • Venules- Collect Blood From Capillaries • Veins- Return Blood To Heart Blood Vess...

coarctation of the aorta -:- congenital narrowing of the aorta Where does coarctation of the aorta normally occur? -:- distal to the origin of the left subclavian Waveforms associated with coarctation of the aorta? (Distally and in abdominal aorta) -:- Decreased flow distal to the obstruction, monophasic flow with continuous flow in diastole in the abdominal aorta Takayasu arteritis -:- presents as hypertrophic area(s) of inflamed of tissue usually found in the aorta and its branc...

Valves ensure______ - Answer-One-way flow of blood through the heart Right AV valve has____ - Answer-three cusps (TRIcuspid valve) Left AV valve has____ - Answer-two cusps (BIcuspid) Left AV valve also called - Answer-biscupid valve or mitral valve Right AV valve also called - Answer-Tricuspid valve Cardiac Output (CO) - Answer-The amount of blood ejected by each ventricle in 1 minute Exercise makes the heart____ - Answer-work harder which increases cardiac output At the beginning of exer...

What is the process for electrical impulses of the heart? - ANSWER-- SA node (the heart's pacemaker) - Upper atrias contract - AV node sends impluses to ventricles - ventricles contract What are the different layers of blood vessels and what are the functions? - ANSWER-Tunica adventitia (outermost) - prevents collapse of blood vessel and provides protection Tunica media (middle) Tunica intima (innermost) Where is the temporal pulse? - ANSWER-In front of ear on the temple Where is ...
