This process is known as secondary growth; it is the result of cell division in the vascular cambium, a lateral meristem, and subsequent expansion of the new cells. These cells then go on to form thickened secondary cell walls, composed mainly of cellulose, hemicellulose and lignin. Where the differences between the seasons are distinct, e.g.
Wood science [1] is the scientific field which predominantly studies and investigates elements associated with the formation, the physical and chemical composition, and the macro- and microstructure of wood as a bio-based and lignocellulosic material.
The term secondary raw material denotes waste material that has been recycled and injected back into use as productive material. Lumber has a high potential to be used as a secondary raw material at various stages, as listed below: Recovery of branches and leaves for use as fertilisers
(2) The Gallbladder, a wood controlled Yang organ, governs decisiveness and judgement. The Gallbladder also stores bile. Imbalance of the Gallbladder can lead to indecisiveness along with obesity. The Gallbladder meridian begins at the outer edge of the eye, moves to the side of the head and trunk, and ends on the outside of the fourth toe. [2]
This inflammation of the gallbladder is known as cholecystitis and is a common indication for surgical removal of the gallbladder, or cholecystectomy. [ 12 ] Occasionally gallstones may become lodged in the common bile duct and obstruct the flow of bile from the gallbladder to the small intestine– this condition is known as ...
In vertebrates, the gallbladder, also known as the cholecyst, is a small hollow organ where bile is stored and concentrated before it is released into the small intestine. In humans, the pear-shaped gallbladder lies beneath the liver , although the structure and position of the gallbladder can vary significantly among animal species.
A section of rosemary stem, an example of a woody plant, showing a typical wood structure. A woody plant is a plant that produces wood as its structural tissue and thus has a hard stem. [ 1 ] In cold climates, woody plants further survive winter or dry season above ground, as opposed to herbaceous plants that die back to the ground until spring .
This facilitates transport of numerous small molecules into the enterocyte from the intestinal lumen. These include broken down proteins, fats, and sugars, as well as water, electrolytes, vitamins, and bile salts. Enterocytes also have an endocrine role, secreting hormones such as leptin.
