Lab 2: Heart
normal bp
120/80
collect & drain oxygen-poor blood from the right atrium; drain directly into right atrium
anterior cardiac veins
arises from left coronary artery
anterior interventricular artery
located in anterior interventricular sulcus
anterior interventricular artery
provides oxygen-rich blood to the anterior portion of the heart
anterior interventricular artery
oxygen-rich blood travels from left ventricle through ASL valve to rest of body
aorta
arises from l. coronary artery
circumflex artery
located in coronary sulcus; supplies l. atrium & posterior left ventricle w/oxygen rich blood
circumflex artery
The Great, Middle, & Small Cardiac veins & anterior cardiac veins return the oxygen-poor blood back to the Coronary Sinus, which drains into the right atrium
coronary circuit
circuit delivers oxygen rich blood to all cardiac muscle cells via the left & right Coronary arteries, Anterior & Posterior Interventricular arteries, Marginal artery & Circumflex artery
coronary circuit
collects oxygen-poor blood from the cardiac veins then drains into the right atrium
coronary sinus
cardiac cycle: diastole - systole -
diastole - relaxed systole - contracted
sound, S2, close of semilunar valves, beginning of ventricular diastole
dub
collects & drains oxygen-poor blood from the anterior portions of right and left ventricles
great cardiac vein
companion vessel to anterior interventricular artery
great cardiac vein
located in anterior interventricular sulcus
great cardiac vein
receives oxygen-poor blood from lower limbs & abdomen
inferior vena cava
delivers oxygen-rich blood to left side of head
l. common carotid artery
passes posterior to pulmonary trunk; branches into anterior interventricular artery
l. coronary artery
delivers oxygen-rich blood to left arm
l. subclavian artery
arises from ascending aorta (2)
left & right coronary artery
connective tissue anchoring aortic arch to pulmonary trunk
ligamentum arteriosum
sound, S1, close of AV valves, beginning of ventricular systole
lub
arises from right coronary artery
marginal artery
located lateral portion of the right ventricle
marginal artery
provides oxygen-rich blood to the lateral side of the right ventricle
marginal artery
collects and drains oxygen-poor blod from the posterior portions of the right and left ventricles
middle cardiac vein
companion vessel with posterior interventricular artery
middle cardiac vein
pulmonary artery carries oxygen __ blood from RV to lungs
poor
veins are oxygen ___; arteries are oxygen ___
poor;rich
arises from right coronary artery
posterior interventricular artery
located in posterior interventricular sulcus
posterior interventricular artery
supplies oxygen-rich to posterior walls of ventricles & interventricular septum
posterior interventricular artery
delivers oxygen-poor blood to lungs
pulmonary arteries
exceptions to artery carries oxygen rich and veins carry oxygen poor
pulmonary artery and vein
Oxygen-poor blood flows to the lungs, via the pulmonary arteries, from the right ventricle through the pulmonary semilunar valve. Oxygen-rich blood flows back to the left atrium, via the pulmonary veins, passes into the left ventricle through the bicuspid/ martial valve, entering the systemic circuit.
pulmonary circuit
oxygen-poor blood travels from right ventricle through PSL valve to lungs
pulmonary trunk
delivers oxygen-rich blood to heart
pulmonary veins
blood flow 3 circuits
pulmonary, systemic, coronary
delivers oxygen-rich blood to right arm & side of head
r. brachiocephalic artery
heart in coronary sulcus; branches into marginal artery & posterior interventricular artery
r. coronary artery
pulmonary vein carries oxygen __ blood from lungs to LA
rich
companion vessel to marginal artery, collects & drains oxygen-poor blood from muscle cells that compose the lateral right ventricle
small cardiac vein
receive oxygen-poor blood from upper limbs & head
superior vena cava
Oxygen-rich blood flows to tissues all over the body, via various blood vessels, from the left ventricle through the aortic semilunar valve into the ascending aorta. Oxygen-poor blood flows back to the right atrium, via the inferior and superior vena cava, then passes into the right ventricle through the tricuspid valve, entering into the pulmonary circuit.
systemic circuit
blood pressure is : __/__
systolic/diastolic
