IMA (Inferior Mesenteric Artery) What are the most distal branches of the aorta that supply blood to the pelvis, abdominal wall, and lower limbs? Common Iliac Arteries (CIA) What vessel is also referred to as the Hypogastric artery? Internal Iliac Artery What vessel runs along the medial side of the psoas mucsle and underneath the inguinal ligament? External Iliac artery What vessel becomes the CFA in the groin region? External Iliac Artery The SFA passes through an opening in what tendon to enter the popliteal fossa? Adductor Hiatus (Adductor Canal or Hunter's Canal) What is another name for the deep femoral artery? Profunda Femoris What is the region called where the SFA terminates and the popliteal artery begins? Adductor Hiatus What 3 branches is sometimes known as the trifurcation? APA, PTA, Peroneal Artery Whats the first branch off distal popliteal artery? ATA - Anterior Tibia Artery What vessel does the ATA become once it crosses the dorsum of the foot?DPA - Dorsalis Pedis Artery What is a major branch of the DPA (dorsalis pedis artery)? Deep Plantar Artery- penetrates the sole of foot, it unites with lateral plantar artery to complete plantar arc. How does the PTA run down the leg? Posterior and Medial side of leg What is the Tibioperoneal Trunk? Short segment between ATA branch and branches of PTA and peroneal arteries. The plantar arch in foot consists of what branch from DPA? Deep plantar artery The plantar arch in foot consists of what branch from the PTA? Lateral plantar artery, which unites with the deep plantar artery Arteries progressively decrease in size from the largest being __ and the smallest being ___? A. Largest = Aorta B. Smallest = Arterioles Arterioles are considered what type of vessels and assist in regulating what? a. Arterioles are considered resistance vessels b. They assist in regulating blood flow through contraction and relaxation. Where does the exchange of nutrients and waste products between blood and tissue take place? Capillaries What is the inner thin layer of the arterial wall called? Tunica intima, which consists of smooth endothelium and connective tissue What layer of the arterial wall is thickest and made up largely of elastic type of smooth mucsle and connective tissue? Tunica media / intermediate layer Which layer of the arterial wall is made up of fibrous connective tissue? Tunica externa / outer layer (adventitia) What layer of the arterial wall contains the vasa vasorum? What is the vasa vasorum?The vasa vasorum tiny vessels found in the adventitial layer of the arterial wall, that carry blood to the walls of the largest arteries. Proximal to aortic arch, what are the first branches of the ascending aorta? Coronary Arteries What events lead up to the beginning of cardiac contractions? 1. Pressure in left ventricle begins to rise 2. Left ventricle pressure exceeds that in the aorta 3. Aortic valve opens; blood is ejected, blood pressure rises What generates the pressure wave to move the blood? Pumping Heart What governs the amount of blood that enters the arterial system? Cardiac output What determines the amount of blood that leaves the arterial system? Arterial pressure and total peripheral resistance Where is pressure greatest in the arterial system? Pressure is greatest at the heart, gradually decreasing as blood moves further away. What 2 things is required for movement of any fluid medium between 2 points? 1. Pathway for fluid to flow 2. Pressure difference / Energy gradient Low resistance yields what type of flow rate? High flow rate The total energy contained in moving fluid is the sum of what 3 energies? 1. Potential (Pressure) 2. Kinetic 3. Gravitational What type of energy is stored energy and is the major form of energy for circulation of blood? Pressure (Potential) Energy, measured in mmHg. What form of energy id equivlent to the weight of the column of blood extending from the heart to the level where pressure is measured?Gravitational energy or Hydrostatic Pressure (HP) What is the tendency of a fluid to resist changes in its velocity? Inertia What 2 things affect the movement of fluid? 1. Physcial properties of the fluid 2. What the fluid is moving through Internal friction within a fluid is measured how? It's measured by its Viscosity What is an example of something that would increase blood viscosity? Decrease blood viscosity? 1. Elevated hematocrit increases viscosity 2. Severe anemia would decrease viscosity Viscosity measures what of a fluid? Viscosity measures the thickness of a fluid. What type of energy loss is due to increased friction between molecules and layers? Viscous energy loss What type of energy loss occurs with deviation from laminar flow, due to changes in direction and / or velocity? Inertial energy loss Whose equation define the relationship between: pressure, resistance, and volume flow? Poiseulle's Equation: Q = P/R ; it helps answer the question of how much fluid moves through a vessel What can occur due to geometry change with or without intra-luminal disease and becuase of curves in vessels? Pressure gradients (Flow separation), they occur in areas with stagnant or little movement. What predicts when fluid becomes unstable? Reynolds Number (Re)- >2000 is the point when laminar (stable) flow turns into turbulent (disturbed) flow In a rigid tube, energy losses are mainly viscous; this can be described by whose principles? Poiseuille's equationWhat kind of flow feeds dilated vascular beds like: ICA, vertebral, renal, celiac, splenic, hepatic? Low resistance flow, which is continous (steady) flow What is one visible sign that you can differentiate a low resistant waveform from a high resistant waveform? The reversal of flow seen in high resistant waveforms. As the inflow pressure falls as a result of stenosis, what is the natural response of the periphery vessels? Vasodilate or vasoconstrict? Vasodilate Exercise should induce peripheral vasodilation, which does what to the distal peripheral resistance? Raise or Lowers? Lowers the peripheral resistance, increasing blood flow. What is the single best vasodilator of resistance vessels within skeletal muscle? ARDMS (RVT) Ultrasound Vascular Registry Review Questions with 100% Correct answers (Latest 2024)
