Question | Answer |
circuit which takes blood to and from the lungs | pulmonary circuit |
circuit in which vessels transport blood to and from the body tissues | systemic circuit |
part of the heart which receives blood from the pulmonary and systemic circuits | atria |
part of heart which function as the pumping chambers for the pulmonary and systemic circuits | ventricles |
where is the opening for the coronary sinus? | the right atrium |
covering of the heart | pericardium |
external layer of the pericardium | fibrous pericardium |
how many layers form the serous pericardium? | 2 |
what is the outer layer of the serous pericardium? | parietal pericardium |
what is the inner layer of the serous pericardium? | visceral pericardium |
another name for the visceral pericardium | epicardium |
the heart wall is comprised of how many layers? | 3 |
the external layer of the heart wall | epicardium |
the epicardium is also known as | visceral pericardium |
middles layer of the heart wall, consisting of cardiac muscle tissue | myocardium |
inner layer of the heart wall, forms the heart valves | endocardium |
referred to as internal divisions between the right atrium and left atrium, and right ventricle from left ventricle | septa |
an external groove that marks the division between the atria and ventricles | coronary sulcus |
external grooves that mark the division between the ventricles on both the anterior and posterior side of the heart | anterior and posterior interventricular sulcus |
the receiving chamber for oxygen-poor blood from the systemic circuit | right atrium |
the superior vena cava is formed in the | right atrium |
receives oxygen-poor blood draining superior to the diaphragm | superior vena cava |
the inferior vena cava is formed in the | right atrium |
receives oxygen-poor blood draining inferior to the diaphragm | inferior vena cava |
receives oxygen-poor blood draining from the walls of the heart itself | coronary sinus |
remnant of a fetal circulatory structure | fossa ovalis |
where is the fossa ovalis found? | right atrium |
valve located between the right atrium and right ventricle (2 names) | tricuspid valve, right AV valve |
the pumping chamber for the pulmonary circuit | right ventricle |
vessel leaving the right ventricle, pumps oxygen-poor blood to the lungs | pulmonary trunk |
cone-shaped muscles projecting from the ventricular wall | papillary muscles |
thin strong bands attached to the papillary muscles and the flaps of the tricuspid valve, help prevent backflow of blood from right atrium to right ventricle | chordae tendinae |
where are the chordae tendinae and papillary muscles located? | the ventricles |
valve located at the base of the pulmonary trunk | pulmonary semilunar valve |
receiving chamber for oxygen-rich blood | left atrium |
receives oxygen-rich blood returning from the right lung | 2 right pulmonary veins |
recevies oxygen-rich blood returning from the left lung | 2 left pulmonary veins |
the four pulmonary veins empty into | left atrium |
located between the left atrium and left ventricle (3 names) | bicuspid valve, mitral valve, left AV valve |
pumping chamber for the systemic circuit | left ventricle |
vessel which leaves the left ventricle | aorta |
valve located at the base of the aorta | aortic semilunar valve |
at rest, the heart beats how many times per minute | 70-80 beats |
which has thicker walls, atria or ventricles? | ventricles |
which ventricle has walls 3 times thicker than the other? | the left ventricle |
this system sets the heart's intrinsic heart rate | conducting system |
the "internal pacemaker" of our heart | sinoatrial node |
the sinoatrial node is located | right atrium |
these autonomic nervous system fibers slow the heart rate | parasympathetic |
these autonomic nervous system fibers increase the heart rate | sympathetic |
these two arteries supply blood to the heart itself | left and right coronary arteries |
this structure drains the blood supply from the walls of the heart | coronary sinus |
c-like structures marking the opening of the vessels in the right atrium | crista terminalis |
