Heart Flashcards
Briefly explain the portal circulation
- venous blood from unpaired abdominal organs (stomach, intestine, pancreas, spleen) absorbed by intestine
- carried to v. portae
- collected in capillary bed in liver
- collected by vv. hepaticae
- conveyed to v. cava inferior

Describe the structure of a semilunar valve
Give another name for the smallest part
- pars densa: lower part
- pars flaccida: upper part
- 2 lunuli: thickened edges
- 1 nodulus (=corpus Arantii): closes cusps
The inflow and outflow tract of the right ventricle are divided by.. ?
- crista supraventricularis
- trabecula septomarginalis
The inflow and outflow tract of the left ventricle is divided by.. ?
How is the structure called?
anterior cusp of bicuspid valve
→ vestibulum aortae
Which vessel leaves the left ventricle?
aorta
What are the 3 layers that make up the heart wall?
- endocardium
- myocardium
- epicardium
Which structures make up the myocardium?
- atrial muscle
- ventricular muscle
Differentiate btw atrial muscle layers
- deep layer: surrounding each atrium
- superficial layer: covers both atria
Differentiate btw ventricle muscle layers
- stratum subendocardiale: forms trabeculae carnae, mm. papillares, sulcus coronarius, sulcus interventricularis ant./post
- stratum musculare: only septum interventr., wall of left ventricle
- stratum subepicardiale: forms vortex cordis
Describe the structure of the endocardium
= continuation of inner layer of wall vessels, therefore:
- endothelium
- conn. tissue
Describe the structure and function of the epicardium
- mesothelium
- conn. tissue
- adipose tissue → smoothes unevenness of heart surface
What is the function of the cardiac skeleton?
- electrical insulation of atria/ventricles
- attachment site for:
- myocardium
- leaflets and cusps of valves
- keeps orifices of valves stable
