回肠，因其盘曲重叠而得名；广肠即回肠中较大的部分；直肠则是广肠的最末一段，向下连接肛门，这被称为谷道或后阴，又名魄门，统称为大肠。广肠长二尺八寸，能容纳谷物九升三合又八分之一合。《难经》记载：大肠重二斤十二两，肛门重十二两。《危言》说：肠者畅也，贵在通畅。
手阳明大肠经对应大肠。大肠是传导之官，负责变化排泄物。其形体长二丈一尺，宽四寸，直径一寸，位于脐右侧，盘曲十六圈，能容纳谷物一斗，水七升半，其上口连接小肠的下口。在天干中属庚，在十二地支中司酉，在五行中属金，在八卦中属兑，与手太阴肺经互为表里。该经脉气血都很旺盛，卯时气血灌注于此。
其病症表现为：牙齿疼痛且肿胀，眼睛发黄，口干，鼻出血，咽喉肿痛，肩前部疼痛，食指和大拇指难以活动，耳聋伴有耳鸣声如钟鸣或嘈杂声，耳后、肩部、肘部和手臂外侧均疼痛。若气机壅满，皮肤坚硬但不痛；若气盛，则脉象太过而发热肿胀；若气虚，则脉象不足而发冷。
该经脉的循行路线，起于食指桡侧端的商阳穴，承接手太阴肺经的气血，行于阳分。由此沿食指上缘上行，经过二间穴、三间穴，出于合谷穴在两骨之间的缝隙，再向上进入阳溪穴在两筋之间；从阳溪穴向上，沿前臂上缘经过偏历穴、温溜穴、下廉穴、上廉穴、手三里穴，进入肘部外侧的曲池穴，沿上臂外侧前缘上行，经过肘髎穴、五里穴、臂臑穴，联络手少阳三焦经的会穴，上行至肩部到达本经的肩髃穴；从肩髃穴的前缘出来，沿巨骨穴上行，与督脉的大椎穴交会，由大椎穴向下，进入足阳明胃经的缺盆穴，沿足阳明胃经的外络，环绕肺脏，再向下穿过膈肌，当与胃经天枢穴相分会属于大肠；其支脉，从缺盆穴上行至颈部，沿天鼎穴、扶突穴上行贯穿面颊，进入下齿缝中，从齿缝复出夹于口角两侧，在人中穴内部左右交叉，左脉向右，右脉向左，上行夹鼻孔两侧，沿禾髎穴、迎香穴，与足阳明胃经交接，然后从承泣穴、四白穴、巨髎穴、地仓穴至头维穴，又从头维穴下行。
The Lung Meridian of Hand-Taiyin has eleven acupoints: Zhongfu (LU-1), Yunmen (LU-2), Tianfu (LU-3), Xiabai (LU-4), Chize (LU-5), Kongzui (LU-6), Lieque (LU-7), Jingqu (LU-8), Taiyuan (LU-9), Yuji (LU-10), and Shaoshang (LU-11).
The Lung Meridian of Hand-Taiyin originates at Zhongfu (LU-1). It is located approximately one cun below Yunmen (LU-2); Yunmen (LU-2) is six cun lateral to Xuanji (CV-21) and two finger-breadths below Jugu (LI-1); Tianfu (LU-3) is sought three cun below the axilla; Xiabai (LU-4) governs conditions when located five cun above the elbow crease; Chize (LU-5) is found in the center of the cubital crease; Kongzui (LU-6) is taken seven cun below the wrist crease; Lieque (LU-7) is one and a half cun above the wrist crease; Jingqu (LU-8) is located in the depression at the radial pulse (Cunkou); Taiyuan (LU-9) is at the head of the transverse crease on the palmar side of the wrist; Yuji (LU-10) can be palpated as a scattered vessel behind the first metacarpal bone joint; Shaoshang (LU-11) is at the medial tip of the thumb. Pricking this point can immediately stop epistaxis (nosebleed). (Note: Xuanji is an acupoint of the Conception Vessel; Jugu is an acupoint of the Large Intestine Meridian of Hand-Yangming).

The sigmoid colon (Hui Chang) is named so because of its coiled and folded structure; the descending colon (Guang Chang) is the larger portion of the sigmoid colon; the rectum is the terminal segment of the descending colon, connecting downward to the anus, which is also called the grain gate (Gu Dao) or posterior yin, alternatively known as the魄门 (Po Men), collectively referred to as the Large Intestine. The descending colon is two chi eight cun long and can hold nine sheng, three he, and one-eighth of a he of grain. *Nan Jing* states that the Large Intestine weighs two jin twelve liang, and the anus weighs twelve liang. *Wei Yan* says: "Chang" (Intestine) implies smoothness/fluidity; it values unobstructed flow.
The Hand-Yangming Large Intestine Meridian corresponds to the Large Intestine. The Large Intestine is the official of transmission, responsible for transformation and excretion. Its body is two zhang one chi long, four cun wide, and one cun in diameter. It is located to the right of the umbilicus, coiling sixteen times, capable of holding one dou of grain and seven sheng and a half of water. Its upper opening connects to the lower opening of the Small Intestine. In the Heavenly Stems, it corresponds to Geng; in the Earthly Branches, it corresponds to You; in the Five Elements, it belongs to Metal; in the Eight Trigrams, it corresponds to Dui. It forms an interior-exterior relationship with the Lung Meridian of Hand-Taiyin. This meridian has abundant Qi and Blood, which pour into it during the Mao hour (5:00–7:00 AM).
Its clinical manifestations include: toothache with swelling, yellowing of the eyes, dry mouth, epistaxis, throat obstruction, pain in the anterior shoulder, difficulty using the index finger and thumb, deafness with tinnitus sounding like bells or buzzing, and pain behind the ear, in the shoulder, elbow, and outer aspect of the arm. If Qi is stagnant and full, the skin becomes hard but painless; if Qi is excessive, the pulse is overactive leading to heat and swelling; if Qi is deficient, the pulse is insufficient leading to cold.
The pathway of this meridian originates at Shangyang (LI-1), located at the radial end of the index finger, receiving Qi and Blood from the Lung Meridian of Hand-Taiyin, and traveling through the Yang aspects. From there, it follows the upper border of the index finger, passes through Erjian (LI-2) and Sanjian (LI-3), emerges at Hegu (LI-4) between the two bones, and ascends into Yangxi (LI-5) between the two tendons. From Yangxi (LI-5), it ascends along the upper border of the forearm, passing through Pianli (LI-6), Wenliu (LI-7), Xia Lian (LI-8), Shang Lian (LI-9), and Shousanli (LI-10), entering Quchi (LI-11) at the lateral end of the elbow. It then follows the anterior border of the upper arm, passing through Zhou Liao (LI-12), Wuli (LI-13), and Binao (LI-14), connecting with the meeting point of the Triple Energizer Meridian of Hand-Shaoyang. It ascends to the shoulder, reaching Jianyu (LI-15) of this meridian. Emerging from the anterior border of Jianyu (LI-15), it ascends along Jugu (LI-15/GB-1 area context, here referring to LI path), meeting the Dazhui (GV-14) of the Du Vessel. Descending from Dazhui (GV-14), it enters the Quepen (ST-12) of the Stomach Meridian of Foot-Yangming, follows the external collateral of the Stomach Meridian, circles the Lung, descends through the diaphragm, and at the junction corresponding to Tianshu (ST-25) of the Stomach Meridian, it belongs to the Large Intestine. A branch arises from Quepen (ST-12), ascending to the neck, following Tianding (SI-14) and Futu (LI-18), ascending through the cheek, and entering the lower gum. It exits the gum, reappears flanking the corners of the mouth, crosses internally at Renzhong (GV-26), with the left channel crossing to the right and the right channel crossing to the left, ascending to flank both sides of the nostrils, following Heliao (SI-19) and Yingxiang (LI-20), where it intersects with the Foot-Yangming Stomach Meridian. It then proceeds from Chengqi (ST-1), Sibai (ST-2), Juliao (ST-3), Dicang (ST-4) to Touwei (ST-8), and descends from Touwei (ST-8).
