The article states that the thoracic duct starts at the level of T12, however while reading Gray's Anatomy for students (2019), on page 233, it states that "The thoracic duct extends from vertebra LII to the root of the neck.". I do not think I am qualified enough so I will leave this to someone more qualified to look into this further. Thank you.

THE THORACIC DUCT

COURSE Is the largest lymphatic vessel in the body. It drains the lower limbs, the abdomen and the left half of the upper trunk (left arm, left thorax, left neck and left half of the head) It begins at the level of the lower border of T12 as a continuation of cisterna chyli - a confluence of several lymphatics of the abdomen and lower limbs, enter the thorax through the aortic opening of the diaphragm to ascend in the posterior mediastinum on the right side of the oesophagus between the thoracic aorta and the azygos vein upto the level of T5 where it decussates to the left side behind the oesophagus and runs upwards in the superior mediastinum on the left side of the oesophagus between the oesophagus and the trachea together with tyhe left recurrent laryngeal nerve upto the neck. In the neck, it arches behind the carotid sheath for about 3-4 cm and then descends to terminate at the confluence between the left subclavian vein and the left internal jugular vein.

The lower lobe of the left lung

Dear Wikipedia contribuitors,

receive a respectful greeting. The article about the right lymphatic duct reads that it drains lymph fluid from:

"... in some individuals, the lower lobe of the left lung."

Can you tell, please:

1. If this is a very uncommon exception (1%-15%) or it is quite common (16% or more).

2. If this is related to racial conditions or something like that.

Besides, if this is not very common, this article (about the thoracic duct) should read

"It collects most of the lymph in the body except that from the right arm and the right side of the chest, neck and head which is collected by the right lymphatic duct; and, in some individuals (around ?% of world population or mostly this people of ? race), from the left lung lower lobe, too. And it drains into the systemic (blood) circulation at the left brachiocephalic vein between the left subclavian and left internal jugular veins.

Thanks in advance!
