What kind of transport is occurring?
Salivary glands create saliva and secrete saliva. Acini, which are collections of cells, are the primary secretory components of salivary glands.
The largest salivary glands, the parotid glands, which are located between the rear of the jaw and each ear, release around 25% of the total volume of saliva when at rest.
The parotid capsule, a tough capsule that encases each gland, is present. Saliva from the parotid is typically watery or serous.
Large amounts of bicarbonate ions are secreted, potassium is secreted, and a significant portion of sodium is actively reabsorbed.
Salivary glands include small collecting ducts that branch out into larger ducts until they unite into one giant duct that exits into the mouth cavity.
Therefore, salivary gland cells produce the enzyme salivary amylase and secrete it into the salivary ducts.

Answer:
Saliva is produced in and secreted from salivary glands. The basic secretory units of salivary glands are clusters of cells called an acini. These cells secrete a fluid that contains water, electrolytes, mucus and enzymes, all of which flow out of the acinus into collecting ducts. Within the ducts, the composition of the secretion is altered. Much of the sodium is actively reabsorbed, potassium is secreted, and large quantities of bicarbonate ion are secreted. Bicarbonate secretion is of tremendous importance to ruminants because it, along with phosphate, provides a critical buffer that neutralizes the massive quantities of acid produced in the forestomach's. Small collecting ducts within salivary glands lead into larger ducts, eventually forming a single large duct that empties into the oral cavity.

Condensation is a process in which the gaseous form of water is converted into liquid. It is very important for the water cycle. This results in the formation of the clouds, fog and dew. For the occurrence of condensation, the air must be saturated. Saturation occurs most commonly when the warm air in the atmosphere cools down to it's dew point. The condensed water vapors and some of the particular matter forms the clouds.
