What else can I help you with?
From the esophagus to the anal canalthe walls of every organ of the alimentary canal are made up of the same four basic layers arrange them in order from the lumen?
Mucosa: Innermost layer with epithelial cells that absorb nutrients. Submucosa: Layer containing blood vessels, nerves, and glands. Muscularis: Layer with smooth muscle for peristalsis. Serosa (or adventitia): Outermost layer that protects and anchors the organ.
What are the layers of walls of every organ of the alimentary canal made up of?
The walls of the alimentary canal consist of four primary layers: the mucosa, submucosa, muscularis externa, and serosa (or adventitia). The mucosa is the innermost layer, made up of epithelial tissue that aids in absorption and secretion. The submucosa contains connective tissue, blood vessels, and nerves, providing support and nourishment. The muscularis externa consists of smooth muscle that facilitates peristalsis, while the outer layer, serosa or adventitia, provides protection and structural integrity.
Which plant material is not acted upon by any enzymes in the human alimentary canal?
Cellulose, found in plant walls, otherwise known as fibre
What separates the Duran mater from the walls of the vertebral canal?
The dura mater is separated from the walls of the vertebral canal by an epidural space, which contains fat and blood vessels. This space provides cushioning and allows for flexibility within the spinal column. Additionally, the dura mater itself is a tough, outermost layer that protects the spinal cord and its surrounding structures.
Are plant cell walls multilayered?
Yes - plant cell walls can have up to three layers. The middle lamella is the outermost layer and contains high levels of pectin. The primary cell wall is a thin, flexible layer found in the middle. The secondary cell wall is a thicker layer on the inside.
Does fiber help food particles travel through the digestive system?
yes. fiber provide bulk to the food moving along the alimentary canal. It helps in peristalsis occurring in the walls of gut. I think its enough :)
What does the epidural space contain areolar and adipose tissue?
The epidural space is the area between the outermost layer of the spinal meninges and the inner walls of the vertebral canal. It contains areolar connective tissue, which provides flexibility and support, as well as adipose tissue, which serves as a cushioning layer and energy reserve. This combination of tissues helps protect the spinal cord and spinal nerves, while also allowing for movement within the vertebral column.
Does a tiger have a cell wall?
No, tigers do not have cell walls. Cell walls are found in plant cells and certain bacteria, but animal cells like those of tigers do not have cell walls. The outermost layer of animal cells is known as the cell membrane.
Is a gizzards a kind of bird?
A gizzard is a part of a bird, not a type of bird. According to Merriam Webster, it's "the muscular enlargement of the alimentary canal of birds that has usually thick muscular walls and a tough horny lining for grinding the food and when the crop is present follows it and the proventriculus. "
What is the outermost structure of a plant cell?
The outermost structure of a plant cell is a cell wall. Plant cells have cell walls for extra protection as they cannot move like animals and protists, whose outermost cell structure is the cell membrane, a thinner protective cover.
What outermost covering of the animal cell?
membrane or plasma membrane.
What is the structer of an artery?
The walls of the arteries are genrally very thick. The innermost layer is made up of epithgelial cells. The middle layer consist mostley of muscle tissue. The outermost layer is made up of flexible connective tissue. The material allows it to withstand the force of the pumping blood. Got it from the TXT book =D
