- Mesenchyme, also known as mucous connective tissue or mucoid connective tissue,[1] is a type of connective tissue found mostly during development of the embryo.[2] It is composed mainly of ground substance with few cells or fibers. It can also be referred to as a group of mucoproteins found in certain types of cysts (etc.), resembling mucus.

Epithelial cells Classically, squamous epithelia are found lining surfaces utilizing simple passive diffusion such as the alveolar epithelium in the lungs. Specialized squamous epithelia also form the lining of cavities such as the blood vessels (endothelium) and pericardium (mesothelium) and the major cavities found within the body.lassically, squamous epithelia are found lining surfaces utilizing simple passive diffusion such as the alveolar epithelium in the lungs.

Overview of the Respiratory System The airways resemble an upside-down tree, which is why this part of the respiratory system is often called the bronchial tree. Large airways are held open by semiflexible, fibrous connective tissue called cartilage. Smaller airways are supported by the lung tissue that surrounds and is attached to them.The walls of the smaller airways have a thin, circular layer of smooth muscle. The airway muscle can dilate or constrict, thus changing airway size.At the end of each bronchiole are thousands of small air sacs (alveoli).he airways resemble an upside-down tree, which is why this part of the respiratory system is often called the bronchial tree. Large airways are held open by semiflexible, fibrous connective tissue called cartilage. Smaller airways are supported by the lung tissue that surrounds and is attached to them.

Respiratory mucous membranes Cells in mucous membranes manufacture mucus and proteins important in defense against bacteria, viruses, fungi, allergens and a variety of irritant particulates. Mucus is a clear slippery fluid that coats the respiratory membranes of the sinuses, nose and lungs.Mucus consists of water, blood cells, digestive enzymes, salt, antibodies, dead cells, bacteria and other microorganisms and foreign pollutants.espiratory mucous membranes. Mucous membranes line all of the bony surfaces of the sinus cavities. The lining is similar to the surface lining of the nasal passageways and airways of the lungs. The surface of this membrane is lined with microscopic cilia.

Respiratory epithelium Classification[edit] The respiratory epithelium lining the upper respiratory airways is classified as ciliated pseudostratified columnar epithelium. This designation is due to the arrangement of the multiple cell types composing the respiratory epithelium.

- The submucosa is the connective tissue that surrounds the mucosa. Large blood vessels and lymphatics and occasional exocrine glands are found in this layer. A network of nerve fibers and neurons cell bodies called the submucosal plexus (Meissner s plexus) is present in this layer.he outer boundary of the mucosa is often marked by a band of smooth muscle arranged in two thin concentric layers, an inner circular layer and outer longitudinal layer. Contraction of the muscularis mucosae agitates the epithelium and alters its shape.

- The interior lining of the nose is a mucous membrane. Healthy lung function is aided by a thin mucus lining. The mucous membrane that lines the urogenital tract can make someone vulnerable to infections passed between sexual partners. Mucosa is commonly found in the respiratory tract.

Simple Squamous Epithelial Tissue which are used for the diffusion of gasses between the capillaries and the alveoli. The layer of heart wall composed of cardiac muscle tissue is called the myocardium.

Mucus This mucus serves to protect epithelial cells (the lining of the tubes) in the respiratory, gastrointestinal, urogenital, visual, and auditory systems in mammals; the epidermis in amphibians; and the gills in fish.asal mucus is produced by the nasal mucosa; and mucosal tissues lining the airways (trachea, bronchus, bronchioles) is produced by specialized airway epithelial cells (goblet cells) and submucosal glands.

What is Ciliated Pseudostratified Columnar Epithelium? Ciliated pseudostratified columnar epithelium is the type of tissue that lines parts of the respiratory system, such as the nasal cavities and trachea. Epithelial tissues generally cover and protect various parts of the body.They can be different shapes, can be layered, and can even secrete mucus.ale sperm makes use of ciliated pseudostratified columnar epithelium in the epididymis. Nasal mucus helps keep bacteria and particles from entering the respiratory system. The trachea is lined with ciliated pseudostratified columnar epithelium.

respiration The collective term for all the structural components through which respiratory gases must diffuse in order to be exchanged between the air in the alveoli and the blood; this consists of the cell membranes and cytoplasm of the type I alveolar cells, the alveolar epithelial basement membrane, the very limited amount of loose fibrous connective tissue present, if any, beneath it, the capillary basement membrane, and the cell membranes and cytoplasm of the capillary endothelial cells.

- The main respiratory surface in humans is the alveoli, which are small air sacs branching off from the bronchioles in the lungs. They are one cell thick and provide a moist and extremely large surface area for gas exchange to occur.

- From Wikipedia, the free encyclopedia. A mucous membrane or mucosa (plural, mucosae or mucosas; Latin tunica mucosa) is a lining of mostly endodermal origin. It consists of an epithelium (a layer, or layers of epithelial cells) and an underlying lamina propria of loose connective tissue.ome mucous membranes are involved with digestion in the absorption of insoluble food molecules and secretion (releasing chemicals from glands). The thick fluid secreted by some mucous membranes and/or associated glands is termed mucus.
