Circulatory System

What side of heart and what chamber fills the apex of the heart?

Which side of the heart is more muscular and why?

What vessels supply blood to the heart itself?

What are auricles?

What is the most ventral vessel on the front of the heart?

What is directly behind/caudal to the pulmonary artery?

Vena cava dumps into:

Contraction of the heart muscle

Relaxation of the heart muscle

Pericardium

Pacemaker of the heart

What blood vessels carry blood from the heart to the lungs?

Chordae Tendineae

Semilunar Valve located between the left ventricle and the aorta

Endocardium

What blood vessels carry blood from the lungs to the heart?

What is the valve between the right atrium and right ventricle of the heart?

Thick muscle layer of the heart wall

Mediastinum

Renal Artery

Renal Vein

Apex of the heart

Base of heart

Epiglottis

Locations for blood collection

Separates the right and left pumping ventricles from each other

These two blood vessels do not contain valves to control blood flow when entering the heart

This slender gap between the parietal and visceral surfaces is filled with fluid to reduce friction between layers as the heart pumps

Where is the majority of the myocardium located?

What are the long fibres of connective tissue that attach the tricuspid valve to the papillary muscles of the heart?

Explain the process that leads to the closing of the tricuspid valve

How many leaflets does the tricuspid valve have?

How many leaflets does the mitral valve have?

Where is the coronary sinus located?

How many chambers does a mammalian heart have?
