A transverse section of the thorax, showing the contents of the middle and the posterior mediastinum. The pleural and pericardial cavities are exaggerated since normally there is no space between parietal and visceral pleura and between pericardium and heart Paricardium is also known as cariac epidemis.

心包，又名心膜，是一個圆锥形雙層纤维浆膜囊，包裹心臟和出入心臟大血管根部。心包的兩層分別为：
語源[编辑]
心包的學名pericardium來自希臘語的περι（環繞、周圍）與κάρδιον（心臟）兩字合成的/perikardion/。
解剖[编辑]
心包是一個堅靭的雙層膜囊，包裹整顆心臟。兩層心包之間的潜在腔隙被称为心包腔[1]，有被叫作心包液的浆液在其中，以保護心臟免受外來撞擊影響，並有润滑作用。
在內層的浆膜心包分为壁层（parietal pericardium）和臟层（visceral pericardium）两层。壁層已跟纖維心包融合成一體，不能分開；臟层又称心外膜（epicardium），是心臟肌肉以外最貼近的保護層[2]。臟壁两层在出入心根部互相移行。两层之间。在心包腔内，臟壁两层折返处的间隙被称为心包窦，主要有心包横窦、心包斜窦和心包前下窦三者。[1]
纤维心包则是由致密的纤维结缔组织组成。它在出入心大血管的根部与后者的外膜相连接[1]。
