In anatomy and physiology, a duct is a circumscribed channel leading from an exocrine gland or organ. Examples include: As ducts travel from the acinus which generates the fluid to the target, the ducts become larger and the epithelium becomes thicker. The parts of the system are classified as follows:

2023年5月25日 · Overview of the anatomy, function and main structures of the lymphatic system. The thoracic duct is the largest lymphatic vessel in the human body. Around 75% of the lymph from the entire body (aside from the right upper limb, right breast, right lung and right side of the head and neck) passes through the thoracic duct.

2023年7月24日 · The thoracic duct is the larger of the two and responsible for lymph drainage from the entire body except for the right sides of the head and neck, the right side of the thorax, and the right upper extremity which are primarily drained by the right lymphatic duct.[1][2]

In human anatomy, the thoracic duct (also known as the left lymphatic duct, alimentary duct, chyliferous duct, and Van Hoorne's canal) is the larger of the two lymph ducts of the lymphatic system (the other being the right lymphatic duct). [1]

The thoracic duct is a major anatomic structure of the upper part of the abdomen, chest, and the lower part of the neck. This article reviews the embryology, anatomy, and multiple variations of the thoracic duct. Proper knowledge of this anatomy should ease understanding the …

2023年4月8日 · The thoracic duct is the main lymphatic vessel for the return of chyle/lymph to the systemic venous system. It drains lymph from both lower limbs, abdomen (except the convex area of the liver), left hemithorax, left upper limb and left side of face and neck.

Key points: • Describe clinical importance, embryologic origin, and typical course of the thoracic duct. • Depict common/lesser-known thoracic duct anatomic variants and discuss their clinical significance. • Outline the common causes of thoracic duct injury and indications for embolization.

The thoracic duct is a structure into which lymph collected from bodily tissues is transported and subsequently discharged into the venous system. You might find these chapters and articles relevant to this topic. The thoracic duct is the largest lymphatic channel in the body, measuring 38 to 45 cm in length and 2 to 5 mm in diameter.

The Thoracic Duct is the largest lymphatic vessel (trunk) or great lymph channel, which drains lymph into the bloodstream from the majority of the body. Appearance of the lymph in thoracic duct is milky white since it includes a product of fat digestion (chyle) from the intestine.

The thoracic duct is a major anatomic structure of the upper part of abdomen, chest, and the lower part of the neck. A precise knowledge of the anatomy of the duct is essential in the safe perfor-mance of any surgical procedures involving these areas.
