Humus is the organic material of the soil formed by the decomposition of the dead plants and animals. It is thick and dark in color (brown or black) and can also be produced by the process of composting.
It is very for the soil as it adds moisture to the soil, enhances the structure of the soil which increases the aeration and drainage. 
It favors the growth of organisms (such as earthworm) helpful for the growth of plants and adds lots of nutrients to the soil, specially nitrogen. 
In contrast, loam is a type of soil which is composed of silt, sand, and clay in 40-40-20 ratio. Regolith referred to the superficial layer covering the solid rocks or bedrock. It is formed by the accumulation of soil, dust, broken rocks etc on the bedrock.

This condition is known as lymphadema. After surgical removal of chain lymph nodes has occurred, the excess of lymph fluids in the lymph vessels might not find its way to the bloodstream as a result of being blocked or other reasons, and hence localized swelling in that area occurs as a result of addition of the fluids. In most cases, lymphadema affects only a single arm or leg, and is commonly brought on by cancer treatment that involves damging or removing lymph nodes.
