A

Visceral layer

19
Q

Inflammation of the endocardium.

A

Endocarditis

20
Q

The name for the collateral circulatory pathways that develop in the coronary blood vessels of the heart over time which allow alternate routes for blood to be delivered to all the locations of the heart, thus reducing the potential risks of heart attack as people age.

A

Anastomoses

21
Q

The technical term for contraction of the heart.

A

Systole

22
Q

The wall that separates the two ventricles of the heart.

A

Interventricular Septum

23
Q

The vessel type that contains oxygenated blood returning to the left atrium from the lungs.

A

Pulmonary veins

24
Q

The muscular layer of the heart

A

Myocardium

25
Q

The ion that is associated with the plateau phase of the hearts contractile muscle cells, helping to prolong depolarization, giving blood time to flow and ensure the heart contracts in unison.

A

Calcium ions (Ca2+)

26
Q

The term that indicates that the electrical impulse for the heart to contract originates in the muscle tissue of the heart rather than from a nerve impulse from the outside.

A

Myogenic

27
Q

The muscle found in the ventricles that attaches to the chordae tendineae which keeps the tricuspid and bicuspid valves from inverting or being pushed into the atria when the ventricles contract.

A

Papillary muscles

28
Q

The blood vessel type that returns blood from the body to the right atrium.

A

Vena Cavas

29
Q

The electrical component of the heart that is found on the outside edges of the ventricles.

A

Purkinje Fibers

30
Q

The valve that blood must pass through to leave the left ventricle to be pumped to the systemic circuit.

A

Aortic Semilunar valve

31
Q

The pacemaker of the heart, that depolarizes quickly and sets the rhythm of heart beating.

A

Sinoatrial Node (SA Node)

32
Q

The blood vessel that carries blood away from the right ventricle toward the lungs.

A

Pulmonary Trunk

33
Q

The expanded (wider) blood vessel structure that collects the blood from the coronary circulation to return it to the right side of the heart, and is found on the posterior side of the heart between the atria and ventricles.

A

Coronary Sinus

34
Q

The ion involved in creating the ‘pacemaker potential’, the slow depolarization away from resting potential within the electrical circuit of the heart.

A

Sodium ions (Na+)
