Thoracic viscera
Plural Cavities
Figure 1.9
Development of serousal cavities
Development of Pleural cavities
Hemo-thorax
Pneumo-thorax
Lung: collapse
Mediastinum

Heart Covering• Pericardial physiology
– Protects and anchors heart– Prevents overfilling

“EKG”(or ECG, electrocardiogram)
• Electrical depolarization is recorded on the body surface
P wave=atrial depolarizationQRS=ventricular depolarizationT wave=ventricular repolarization
Cardiac muscle(microscopic)
