Mucus is able to absorb water or dehydrate through pH variations. The swelling capacity of mucus stems from the bottlebrush structure [32] of mucin within which hydrophilic segments provide a large surface area for water absorption. Moreover, the tunability of swelling effect is controlled by polyelectrolyte effect.
Phlegm. Phlegm (/ ˈflɛm /; Ancient Greek: φλέγμα, phlégma, "inflammation", " humour caused by heat") is mucus produced by the respiratory system, excluding that produced by the throat nasal passages. It often refers to respiratory mucus expelled by coughing, otherwise known as sputum. Phlegm, and mucus as a whole, is in essence a water ...
t. e. A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes ...
Mucus is typically clear and thin, but it can change color and consistency, depending on your health. If your mucus is yellowish…. Yellowish mucus typically means that your white blood cells are ...
Mucous gland. Vertical section of foliate papilla of the rabbit, passing across the folia. (Serous gland labeled at bottom right.) Human submaxillary gland. At the right is a group of mucous alveoli, at the left a group of serous alveoli. Mucous glands, also known as muciparous glands, are found in several different parts of the body, and they ...
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).
There are glands and mucus produced by goblet cells in parts, as well as smooth muscle, elastin or cartilage. The epithelium from the nose to the bronchioles is covered in ciliated pseudostratified columnar epithelium, commonly called respiratory epithelium. [12] The cilia beat in one direction, moving mucus towards the throat where it is ...
The intestinal mucosal barrier is a heterogeneous entity composed of physical, biochemical, and immune elements elaborated by the intestinal mucosa. The central component is the intestinal epithelial layer, which provides physical separation between the lumen and the body. The secretion of various molecules into the lumen reinforces the barrier ...
