What covers the heart?
Pericardium
Give the layers of the pericardium

Where is the papillary muscles located in the right ventricle?
-
M. papillaris subarteriosus

- On the septum
- Next to sulcus interventricularis subsinosus
-
M. papillaris magnus
- On the parietal wall
- The biggest one
Where is the tricuspid valves located?
Give the name of the cusps
Right ventricle:

Cuspis septalis
- Originate from interventricular septum
- On septum
-
Cuspis parietalis

Where is the semilumar valves located?
Give the name of the cusps
Right ventricle:
-
Valva semilunaris sinister
- Towards sulcus interventricularis paracoronalis
-
Valva semilunaris dexter
- Just above crista semilunaris

Where is the mm. pectinati located?
Left atrium and right atrium
Where is the papillary muscles located in the left ventricle?
On the parietal wall:
- M. papillaris subauricularis
- M. papillaris subatrialis
Where is the bicuspid valves located?
In the left ventricle, papillary muscles attached to them:
- Cuspis parietalis
- Cuspis septalis
Give the pathway of the blood flow
Venous/deoxygenated blood to RA
→ RV
→ Pulmonary trunk (arteries)
→ Lungs to be supplied with oxygen
→ Oxygenated blood through pulmonary veins
→ LA
→ LV
→ Aorta
→ Systemic circulation
