小肠重二斤十四两，长三丈二尺，广二寸半，径八分分之少半，左回叠积十六曲，容谷二斗四

手太阳经小肠 小肠者，受盛之官，化物出焉。其体长三丈二尺，左回叠十六曲。其上口接胃之下口，其下口
按大肠之上口，在脐上一寸水分穴，至是泌别清浊；其水液清者入膀胱，渣滓浊者入大肠。在五行属火，在八卦为离，
与手少阴为表里。其经多血而少气，未时气血注此。
其见证也，嗌痛，额颔肿痛，不可以顾，腰似折，耳聋目黄，颊肿，颈、颔、肩、 、肘、臂外后廉痛。

手少阴心经的九个穴位已经列成歌诀：极泉、青灵、少海位置较深，从灵道、通里延伸而来，经过阴郄、神门，抵达少府和少冲可以寻得。
手少阴心经起始于极泉穴，位于腋下筋脉之间，动脉进入胸部（手臂内侧腋下筋间，动脉入胸），青灵穴在肘上三分处取穴（此时举起手臂取穴），少海穴在肘端后方五分处（肘内侧关节后大骨外侧，距离肘端五分，屈肘向头部方向可找到），灵道穴在掌后一寸半处，通里穴在腕后一寸处相同位置，阴郄穴在腕后方半寸处，神门穴在掌后兑骨隆起处，少府穴在节后与劳宫穴直对的位置，小指内侧可取到少冲穴。

小肠重二斤十四两，长三丈二尺，宽二寸半，直径八分之三分之一，向左回旋叠积十六个弯曲，容量能容纳谷物二斗四升，水六升三合的大多数。
手太阳小肠经所属的小肠，是受盛之官，负责消化食物并排出糟粕。其形体长三丈二尺，向左回旋叠积十六个弯曲。其上口连接胃的下口，其下口对应大肠的上口，位于脐上一寸的水分穴处，在此处分别清浊；其中清稀的水液进入膀胱，浑浊的渣滓进入大肠。在五行中属火，在八卦中为离卦，与手少阴心经互为表里。其经脉多血而少气，未时气血注入此经。
其临床表现有：咽喉疼痛，额角和颌部肿痛，不能回顾，腰部像折断一样疼痛，耳聋，目黄，脸颊肿胀，颈部、颌部、肩部、肘部、臂部外侧后缘疼痛。
其经脉的走向，起始于小指末端外侧的少泽穴，接受手少阴心经的气血交接。由此沿着手指外侧的前谷、后溪穴上行至腕部，出踝中经过腕骨、阳谷、养老穴；从养老穴直上，沿着臂骨下廉经过支正穴，出于时内侧两筋之间，经过小海穴，向上沿着臂外后缘，行走在手阳明、手少阳经的外侧，出于肩解，绕过肩膀HT（此处原文可能有误或特指某点，依原文保留）上肩，经过肩贞、天髎俞（原文“ 俞”推测为天髎或类似穴，依原文保留）、天宗、秉风、曲垣、肩外俞、肩中俞等穴位，向上会合于督脉的大椎穴，分左右相交于两肩之上；由此进入足阳明胃经的缺盆，沿着肩膀向腋下行进，当任脉膻中的部位，联络心脏，沿着胃系向下穿过横膈膜，经过任脉的上脘、中脘，到达胃下行于任脉外侧，当脐上二寸的部位，归属于小肠；其分支，从胃的缺盆处，沿着颈部的天窗、天容穴，上行至脸颊抵住颧骨，上行至目外角的锐明穴（原文“锐 ”推测为锐明或瞳子髎附近，依原文保留），经过足少阳胆经的瞳子髎穴，却进入耳中，沿着听宫穴终止；另一分支，别行沿着脸颊上行，抵住鼻子，到达目内角的睛明穴，以斜络的方式联系颧骨，并与足太阳膀胱经相交。
The nine acupoints of the Hand-Shaoyin (Heart) Meridian are completed in the song: Jiquan (HT1), Qingling (HT2), and Shaohai (HT3) are deep; extending from Lingdao (HT4) and Tongli (HT5), passing through Yinxi (HT6) and Shenmen (HT7), one can locate Shaofu (HT8) and Shaochong (HT9).
The Hand-Shaoyin Heart Meridian originates at Jiquan (HT1), located between the tendons in the axilla, where the artery enters the chest (within the arm's interior below the axilla, the artery enters the chest). Qingling (HT2) is taken three fen above the elbow (raise the arm to locate it). Shaohai (HT3) is five fen posterior to the end of the elbow (lateral to the large bone posterior to the medial joint of the elbow, five fen from the elbow end; flex the elbow towards the head to find it). Lingdao (HT4) is one cun and half a fen distal to the palm. Tongli (HT5) is one cun distal to the wrist. Yinxi (HT6) is half a cun distal to the wrist. Shenmen (HT7) is at the prominence of the metacarpal bone distal to the palm. Shaofu (HT8) is directly opposite Laogong (PC8) posterior to the joint. Shaochong (HT9) is taken on the medial side of the little finger.

The small intestine weighs two jin and fourteen liang, is three zhang and two chi long, two cun and half wide, with a diameter of eight fen and one-third of a fen. It loops leftward and stacks into sixteen curves, with a capacity to hold two dou and four sheng of grain, or six sheng and three he of water (the majority part).
The Small Intestine, belonging to the Hand-Taiyang Meridian, is the "Official of Reception and Transformation," responsible for receiving and transforming food. Its body is three zhang and two chi long, looping leftward with sixteen curves. Its upper opening connects to the lower opening of the Stomach; its lower opening corresponds to the upper opening of the Large Intestine, located one cun above the umbilicus at the Shuifen (CV9) acupoint, where clear and turbid substances are separated; the clear liquid enters the Bladder, while the turbid residue enters the Large Intestine. In the Five Elements, it belongs to Fire; in the Eight Trigrams, it corresponds to Li (Fire); it forms an exterior-interior relationship with the Hand-Shaoyin Heart Meridian. Its meridian contains much blood and little qi, with qi and blood flowing into it during the Wei hour (1 PM - 3 PM).
Its clinical manifestations include: sore throat, swelling and pain in the forehead and jaw, inability to look back, waist pain as if broken, deafness, yellow eyes, swollen cheeks, and pain along the posterior-lateral aspect of the neck, jaw, shoulder, elbow, and arm.
The pathway of its meridian originates at the lateral tip of the little finger at the Shaose (SI1) acupoint, receiving the connection from the Hand-Shaoyin Heart Meridian. From there, it follows the anterior aspect of the lateral side of the hand, passing through Qiangu (SI2), Houxi (SI3), ascending to the wrist, exiting the ankle region, passing through Wanggu (SI4), Yanggu (SI5), Yanglao (SI6); from Yanglao (SI6) straight up, following the lower border of the forearm bone through Zhengzheng (SI7), emerging between the two tendons on the medial side of the elbow, passing through Xiaohai (SI8), ascending along the posterior-lateral aspect of the arm, running external to the Hand-Yangming and Hand-Shaoyang meridians, exiting the shoulder joint, circling around the shoulder [HT], ascending the shoulder, passing through Jianzhen (SI9), Tianliao (SI10), Tianzong (SI11), Bingfeng (SI12), Qu Yuan (SI13), Jian Wai Shu (SI14), and Jian Zhong Shu (SI15); ascending to meet the Du Mai at Dazhui (GV14), crossing left and right above both shoulders; from here entering the Clavicular Fossa (Quepen) of the Foot-Yangming Stomach Meridian, descending along the shoulder towards the axilla, aligning with the Danzhong (CV17) point of the Ren Mai, connecting to the Heart, following the stomach system downward through the diaphragm, passing through Shangwan (CV13) and Zhongwan (CV12) of the Ren Mai, reaching the exterior of the Ren Mai as it descends past the Stomach, at the level of two cun above the umbilicus, belonging to the Small Intestine; its branch, from the clavicular fossa of the Stomach, follows the Tianchuang (SI16) and Tianrong (SI17) points of the neck, ascends to the cheek to reach the zygomatic bone, ascends to the outer canthus of the eye [Ruiming/Tongziliao area], passes through the Tongziliao (GB1) acupoint of the Foot-Shaoyang Gallbladder Meridian, then enters the ear, terminating along the Tinggong (SI19) acupoint; another branch diverges, following the cheek upwards, reaching the nose, arriving at the inner canthus of the eye at the Jingming (BL1) acupoint, linking obliquely to the zygomatic bone, and intersecting with the Foot-Taiyang Bladder Meridian.
The Foot-Taiyang Bladder Meridian originates at Jingming (BL1) and Tongtian (BL7); from Tongtian (BL7), it runs obliquely, crossing left and right at Baihui (GV20) on the vertex, with branches descending.
