mucous
Both forms have a single Body_orificeand body cavity that are used for digestion and Respiration_(physiology), so yes, cnidarians do have a respiratory system.
mucus secretion is important because your body needs to keep your mouth, nasal cavity (the inside of your nose)and lungs moist and to keep the mucus membranes protected. it also is found in the stomach and intestines.
What is the dome-shaped sheet of muscle that forms the bottom of the chest cavity?The dome-shaped sheet of muscle that forms the bottom of the chest cavity is called Diaphragm.
The tissue type that forms the wall of the peritoneal cavity is a type of epithelial tissue known as mesothelium. Mesothelium lines the peritoneal cavity and its organs, providing a protective and lubricating surface for smooth organ movement within the cavity.
The digestive cavity is primarily lined by epithelial tissue, specifically simple columnar epithelium in most parts of the digestive tract. This type of tissue facilitates absorption and secretion, allowing for efficient processing of food. Additionally, smooth muscle tissue is present in the walls of the digestive cavity, aiding in the movement of food through peristalsis. Together, these tissue types work to form the functional structure of the digestive cavity.
The bone that forms the roof of the eye cavity is the frontal bone. It also forms the forehead and part of the top of the skull.
Ciliated and pseudostratified columnar epithelial cells plus goblet cells for the secretion of mucin.
pseudocoelom
It should only be capitalized if it forms part of a title.
The frontal bone forms the rostral (anterior) wall of the cranial cavity. It is located at the front of the skull and is responsible for protecting the brain.
forms because of the expension of the epiblast layer
The ethmoid bone connects the orbit to the nasal cavity. It forms part of the side walls and roof of the nasal cavity, and also contributes to the medial wall of the orbit.
