经云：小肠者受盛之官，化物出焉。
又云：小肠后附于脊，前附于脐，上左回叠，积十六曲，大二寸半，
径八分分之少半，长三丈二尺。受谷二斗四升，水六升三合合之大半。
又云：小肠上口在脐上二寸近脊，水谷由此而入，复下一寸，外附于脐，
为水分穴，当小肠下口，至是而泌别清浊，水液渗入膀胱，滓秽流入大肠。
又云：是经多血少气。

在小指本节末端取少府穴；在小指内侧取少冲穴。
注释：[1] 极泉穴，位于腋下臂内侧两筋之间的动脉处，其脉气引动胸中，此处即为该穴位。
[2] 从极泉穴向下行至肘部，在肘上三寸处，伸肘举臂时取之，此即青灵穴。
[3] 从青灵穴下行至肘内侧缘，节后骨大，距肘端外侧五分，即肘内横纹头，屈肘向头部方向取之，此即少海穴。
[4] 从少海穴下行一寸五分，此即灵道穴。
[5] 从灵道穴下行五分，沿腕侧外方腕后一寸的凹陷中，此即通里穴。
[6] 从通里穴向内行五分，在掌后脉中腕后五分处，此即阴郄穴。
[7] 从阴郄穴行至掌后尺侧锐骨端的凹陷中，此即神门穴。
[8] 从神门穴行至手小指本节末端，外侧骨缝凹陷中，此即少府穴。

医经记载：小肠是受盛之官，负责消化食物并分出清浊。
又说：小肠后方附着于脊柱，前方附着于脐部，向上向左回旋重叠，共有十六个弯曲，直径二寸半，
管径八分又三分之一分，长度三丈二尺。能容纳谷物二斗四升，水六升三合加上大半合。
又说：小肠的上口在脐上二寸近脊柱处，水谷由此进入，再下一寸，外部附着于脐，
此处为水分穴，正当小肠下口，至此分别清浊，水液渗入膀胱，糟粕流入大肠。
又说：这条经脉多血少气。

The Hand-Shaoyin Heart Meridian originates at Jiquan (HT1), located between the tendons in the axilla, where the arterial pulse is felt and radiates to the chest; Qingling (HT2) is located three cun above the elbow; Shaohai (HT3) is located five fen posterior to the medial end of the cubital crease;
Lingdao (HT4) is located one and a half cun proximal to the wrist crease; Tongli (HT5) is located one cun proximal to the wrist crease; Yinxi (HT6) is located half a cun proximal to the wrist crease on the ulnar side; Shenmen (HT7) is located in the depression at the radial border of the pisiform bone (ulnar styloid prominence);
Shaofu (HT8) is located at the distal end of the fifth metacarpophalangeal joint; Shaochong (HT9) is located on the ulnar side of the little finger.
Notes: [1] Jiquan (HT1) is located between the tendons on the medial aspect of the upper arm in the axilla, where the arterial pulse is palpable and its qi radiates to the chest; this is the location of the acupoint.
[2] Descending from Jiquan (HT1) to the elbow, Qingling (HT2) is located three cun above the elbow; it is accessed by extending the elbow and raising the arm.
[3] Descending from Qingling (HT2) to the medial margin of the elbow, past the prominent bone, five fen lateral to the end of the elbow, i.e., at the head of the medial cubital crease; it is accessed by flexing the elbow towards the head; this is Shaohai (HT3).
[4] Descending one cun and five fen from Shaohai (HT3), this is Lingdao (HT4).
[5] Descending five fen from Lingdao (HT4), along the lateral side of the wrist in the depression one cun proximal to the wrist crease, this is Tongli (HT5).
[6] Moving five fen medially from Tongli (HT5), in the vessel proximal to the wrist crease by five fen, this is Yinxi (HT6).
[7] From Yinxi (HT6) moving to the depression at the end of the ulnar styloid process (radial border of the pisiform) at the wrist, this is Shenmen (HT7).
[8] From Shenmen (HT7) moving to the distal end of the fifth metacarpophalangeal joint of the hand, in the depression of the lateral interosseous space, this is Shaofu (HT8).
[9] From Shaofu (HT8) moving to the medial side of the little finger, at a distance from the nail corner resembling the width of a leek leaf, this is Shaochong (HT9) (see Figure 52).

Medical classics state: The Small Intestine is the official responsible for reception and transformation, separating the clear from the turbid.
It is also stated: The Small Intestine is attached posteriorly to the spine and anteriorly to the umbilicus. It loops upward and to the left, forming sixteen curves. Its diameter is two and a half cun,
and its lumen diameter is eight fen plus one-third of a fen. Its length is three zhang and two chi. It can hold two dou and four sheng of grain, and six sheng, three he, plus more than half a he of water.
It is further stated: The upper opening of the Small Intestine is two cun above the umbilicus, near the spine, where food and drink enter. One cun below this, externally attached to the umbilicus,
is the Shuifen (CV9) acupoint, which corresponds to the lower opening of the Small Intestine. Here, the clear and turbid are separated; fluid seeps into the Bladder, while waste flows into the Large Intestine.
It is also stated: This meridian has abundant blood but scarce qi.
The Nan Jing (Classic of Difficult Issues) states: The Small Intestine weighs two jin and fourteen liang. (See Figure 53)
