From the lungs the bacilli are carried by the lymphatics to the lymph nodes at the root of the lungs, in which a similar process takes place; this, on the whole, is favorable, because further extension by this route is for a time blocked.
Between the capillary vessels and the lymphatics is the tissue fluid, in which all the exchange takes place.
At various places along the lymphatics are little spongelike lumps of tissue known as lymph nodes; the particular spongy substance of which they are composed is called adenoid tissue.

If, moreover, as is probably the case, the lymphatics commence as closed capillaries, we have a further difficulty in explaining how the fluid is driven through the lymphatic wall.
Thus according to this theory the lymphatics are open capillary vessels at their origin in the tissues along which the tissue fluid is driven.
