What are the three layers of an artery and state their function?
The three layers of an artery are Endothelium, smooth muscle, and connective tissue.
What are the structure?
Venules are small blood vessels with three basic layers. These layers are an inner membrane called an endothelium, a middle layer of muscle tissue, and the outer layer, which is made of fibrous connective tissue.
How many layers of cells does roundworm have?
The body has three tissue layers and a fluid-filled false body cavity, meaning the cavity is between the inner and middle layers rather than the middle layer and the outer layer, as it is in complex animals.
How is the stomach different from other digestive organs?
The stomach is different from other organs of the digestive system because it has three layers of muscle in the muscular is externa. These are the inner oblique layer, the middle circular layer and the outer longitudinal layer.
What are the venules structure?
Venules are small blood vessels with three basic layers. These layers are an inner membrane called an endothelium, a middle layer of muscle tissue, and the outer layer, which is made of fibrous connective tissue.
What are three types of muscles in the digestive system?
smooth muscle, cardiac (say: kar-dee-ak) muscle, and skeletal (say: skel-uh-tul) muscle.
What are the the three layers of tissue during embryonic development and what structure do each of them develope into?
The three layers of tissue in embryonic development are ectoderm, mesoderm, and endoderm. The ectoderm develops into structures such as the nervous system, skin, and hair. The mesoderm gives rise to muscles, bones, and circulatory system. The endoderm develops into internal organs such as the digestive system and respiratory system.
Respiratory and digestive organs develop from the what in gastrulation?
Gastrulation is defined as a phase early in the embryonic development of most animals, during which the single-layered blastula is reorganized into a trilaminar structure known as the gastrula. These three germ layers are known as the ectoderm, mesoderm, and endoderm. These develop into the respiratory and digestive organs.
What is the fate of the archenteron in the adult frog?
The archenteron develops into digestive tract. It is associated with the inner of the three germ layers, the ectoderm.
How many tissue layers does a mollusca have?
Molluscs typically have three main tissue layers: the outer layer (epidermis), middle layer (connective tissue), and inner layer (gastrodermis). These layers help provide structure and support to the mollusc's body.
What produces the striations of a skeletal muscle cell?
Skeletal muscle is one of the three types of muscle and it is a structure of a striated muscle tissue. The muscle is made up of myocytes or muscle fibers.
This structure has been shown to be composed of three distinct zones or layers and is semipermeable?
plasma membrane
