A spit may be considered a special form of a shoal. As spits grow, the water behind them is sheltered from wind and waves, and a salt marsh is likely to develop. Dungeness Spit in the Strait of Juan de Fuca, on the U.S. Pacific coast. Wave refraction can occur at the end of a spit, carrying sediment around the end to form a hook or recurved ...

Saliva on a baby's lips. Saliva (commonly referred to as spit or drool) is an extracellular fluid produced and secreted by salivary glands in the mouth.In humans, saliva is around 99% water, plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).
Therefore, many spits stretch to the south into the sea and are continuations of the (right) river banks (see table and map). The Chushka and Tuzla spits are located inside the Strait of Kerch; the former spit is formed by the outflow of water from the Azov Sea to the Black Sea and therefore also faces south, whereas the latter is facing north ...
They are 1 to 2 mm in diameter and unlike the major glands, they are not encapsulated by connective tissue, only surrounded by it. The gland has usually a number of acini connected in a tiny lobule. A minor salivary gland may have a common excretory duct with another gland, or may have its own excretory duct.
These families are best known for the nymphal stage, which produces a cover of foamed-up plant sap visually resembling saliva; the nymphs are therefore commonly known as spittlebugs and their foam as cuckoo spit, frog spit, or snake spit. This characteristic spittle production is associated with the unusual trait of xylem feeding.
Larvikite rocks shipped from Norway now defend the start of the spit. The spit formed from loose flint pebbles which had been eroded from the cliffs further west. [5] Although originally formed by natural processes, Hurst Spit has been declining in volume, probably since the 1940s when coast protection works in Christchurch Bay first began to interrupt the flow of the shingle towards the spit. [6]
It has been estimated that there are 2.3 million m 3 (82 million ft 3) of shingle in the spit, [3] 97 per cent of which is derived from flint. [ 4 ] The Point was formed by longshore drift and this movement continues westward; the spit lengthened by 132.1 m (433 ft) between 1886 and 1925. [ 5 ]
