right shoulder

base of the heart points toward the ____ and lines beneath the second rib

Pericardium

encloses the heart

parietal pericardium

outer later of the pericardium

visceral pericardium

innermost layer of the pericardium and the outermost later of the heart wall

Pericardial cavity

stores lubricating serous fluid

atria

receiving chambers; assist with filling the ventricles

ventricles

discharging chambers; pumps the blood

interatrial septum

divides the atria

interventricular septum

divides the ventricles

superior and inferior vena cava

receives the oxygen-poor blood and pumps it to the pulmonary trunk

pulmonary artery

carry blood to lungs for it to be oxygenated

pulmonary veins

passage of the oxygenated blood back to the left side of the heart

pulmonary circulation

passageway from the right ventricle to the lungs and back to the left atrium

aorta

where blood is pumped after the oxygenated blood returned to the left atrium and into the left ventricle

systemic circulation

passageway from the left

Left

Which side is bicuspid valve

Right

Which side is tricuspid valve

left

Which side of heart pumps blood to other parts of body

right

Which side of heart pumps blood to lungs

Atrioventricular valves

First heart sound; located between atria and ventricles; prevent backflow into the atria when ventricles contract

Chordae Tendineae

tiny white cords that anchor the cusps to the walls of the ventricles

Semilunar valves

second heart sound; guards the bases of the two large arteries leaving the ventricular chambers;

Cardiac diastole

all chambers are relaxed and blood flows into the heart

Atrial systole

atria contract, pushing blood into the ventricles

ventricular systole

ventricles contract, pushing blood out of heaert
