● Internally Ithe Ibody Iis Idivided Iinto Icavities Ito Idefine Ilocation Iand Ispecification
○ 2 Imajor Icavities
■ Dorsal
● 2 Imajor Isubdivisions
○ Cranial I- Ibrain
○ Vertebral I- Ispinal Icavity
● Lined Iby I3 Ilayers Iof Idelicate Itissues Icalled Imeninges
● Helped Ito Iprotect Iand Iline Ithe Ibrain Ias Iwell Ias Ithe Ispinal Icord
■ Ventral
● 2 Imajor Isubdivisions Idivided Iby Ithe Idiaphragm
○ Superior I(Thoracic Icavity)
■ Left Iportion I- Ipleural Icavity Isurrounding Ithe Ilungs
● Lines Iby I2 Imembrane Icalled Ipleura
● Outer Ilayer Iis Iparietal Ipleura
○ Lines Ithe Ithoracic Icavity Iitself
● Inner Ilayer Iis Ivisceral Ipleura
○ Cover Ithe Isurface Iof Ithe Ilungs Ithemselves
● In IBetween Ithe Iinner Iand Iouter Ipleura, Ithere Iis Ia Ipotential Ispace Icalled Ipleural Icavity
○ Filled Iwith Ipleural Ifluid
○ Any Ikind Iof Iinflammation Ithat Ioccurs Iin Ihere Iresults Iin Ipain
○ Pleurisy I- Iinflammation Iof Ithe Ipleural Ilinings
■ Right Iportion
■ Medius Istima
● Median Iportion Iof Ithe Ithoracic Icavity
● Heart Iand Iall Iof Iits Ivessels
● Esophagus
● Trachea
● Thymus Igland
● Pericardial Icavity I-small Iarea Isurrounding Ithe Iheart Icontaining Ipericardium
○ Outer Ilayer Icalled Iparietal Ipericardium
○ Inner Ilayer Icalled Ivisceral Ipericardium Icovering Ithe Isurface Iof Ithe Iheart
○ Pericardial Icavity Icarrying Ifluid
○ Pericarditis I- Iinflammation Iof Ithe Iheart Ilining
○ Inferior I(abdominopelvic Icavity)
■ Abdominal Icavity
● Anything Iabove Ithe Ibrim Iof Ithe Ipelvis I(area Iof Iour Ihips
● Most Iof Ithe Idigestive Iorgans, Ikidneys, Iureters
● Peritoneum I- I2 Ilayered Ivery Imoist Imembrane Ithat Iwill Iline Ithe Icavity Ior Icover Ithe Iorgans
○ Parietal I- Ilines Ithe Iabdominal Ipelvic Icavity
○ Visceral I- Icover Ithe Isurface Iof Ithe Iinternal Iorgans
○ Peritoneal Icavity I- Ispace Ibetween Iand Ifilled Iwith Ifluid
■ Peritonitis I- Iinflammation Iof Ithis Iarea
○ We Idescribe Imost Iorgans Ias Ibeing Icovered Iwith Ithis Iperitoneum
○ Some Iare Ireferred Ito Ias Iretroperitoneum
