| lung diseases, interstitial | A heterogeneous group of noninfectious, nonmalignant disorders of the lower respiratory tract, affecting primarily the alveolar wall structures but also often involving the small airways and blood vessels of the lung parenchyma. "interstitial" refers to the fact that the interstitium of the alveolar walls is thickened, usually by fibrosis. This group of diseases is usually inflammatory. (12 Dec 1998) |
| lung diseases, obstructive | Any disorder marked by persistent obstruction of bronchial air flow. (12 Dec 1998) |
| lung diseases, parasitic | Infections of the lungs with a parasite. They are caused most commonly by nematodes (roundworms). (12 Dec 1998) |
| lymphatic diseases | Diseases of lymph or lymph vessels. (12 Dec 1998) |
| absolute system of units | A system based on absolute units accepted as being fundamental (length, mass, time) and from which other units (force, energy or work, power) are derived; such system's in common use are the foot-pound-second, centimeter-gram-second, and meter-kilogram-second system's.

| absorbent system | <anatomy> The tissues and organs (including the bone marrow, spleen, thymus and lymph nodes) that produce and store cells that fight infection and the network of vessels that carry lymph. (12 May 1997) |

(05 Mar 2000) |

| balanced lethal system | <genetics> A population with non-linked, recessive alleles of a gene, where an individual who has two copies of the recessive allele and is therefore homozygous is dead, while an individual who has only one copy of it, and one copy of a different allele (and is heterozygous) survives.
