Submucosa
The gaseous layer surrounding a planet is Atmosphere. Each planet has different atmospheric content.
The substances that leave the lumen of the nephron are reabsorbed into the bloodstream through the peritubular capillaries surrounding the nephron. They are then carried away from the kidneys and circulate throughout the body. Some waste products may continue on to be excreted in the urine.

The ozone layer is contained in the second layer of Earth's atmosphere, called the Stratosphere.
The tunica intima is the innermost layer containing mostly endothelium, the one through which the lumen runs. Surrounding this is tunica media which mostly muscle tissue. And finally surrounding this is the outermost layer, the tunica adventitia which is mostly connective tissue.
It lines the lumen of the vessels, and is a thin layer of endothelium.

No, the lumen is not a layer of the digestive tract; rather, it refers to the hollow space within the digestive organs where food passes through. The digestive tract is composed of several layers, including the mucosa, submucosa, muscularis, and serosa. The lumen is surrounded by these layers, playing a crucial role in the digestive process.
The mucosa consists of mucosal glands, crypts, and other stuff
The layer of gas surrounding earth is the atmosphere.

The layer of the digestive tract that secretes mucus into the lumen is called the mucosa. This innermost layer is composed of epithelial tissue, connective tissue, and smooth muscle, and it plays a crucial role in protecting the digestive tract and facilitating the movement of food. The mucus secreted helps lubricate the passage of food and provides a barrier against pathogens.
The first layer is Litter, the third is Humus, so the second layer would be Duff.
The rigid layer of Earth surrounding the asthenosphere is the lithosphere. It is composed of the crust and the upper portion of the mantle and is broken into tectonic plates that float on the semi-fluid asthenosphere below.
