Answer:
Most correct answer is all of the germ layers
Explanation:
Mucous membranes constitute the innermost layer of a number of hollow organs (i.e.: gastrointestinal tract). They are composed of an epithelial lining which overlies a deeper layer of connective tissue. Typically, each of these components arises from a different germ layer. For instance: the mucous lining of the gut arises from a combination of endoderm-derived epithelium and lateral mesoderm-derived connective tissue. Other mucous membranes may have different origins, for example: The mucous lining of the oral cavity is composed of ectoderm-derived epithelium and underlying connective tissue derived from head mesenchyme (combination of cephalic neural crest and paraxial mesoderm).
Summary:
Mucous Membrane = Epithelium (derived mainly from endoderm, followed by ectoderm, rarely mesoderm) + Underlying Connective Tissue (usually mesoderm)
Answer:
The correct answer is B. The mucosa is responsible for absorption and secretion.
Explanation:
The mucosa is the deepest layer of the intestinal tract, surrounding the lumen, or space inside the tube. This layer comes into direct contact with food (or bolus) and is responsible for absorption and secretion, which are important processes in digestion.
The mucosa is highly specialized in each organ of the intestinal tract, facing a low pH in the stomach, absorbing a multitude of different substances in the small intestine and also absorbing specific amounts of water in the large intestine.
Answer: I think you couldn´t get hepatitis c
Explanation:
P wave is the atria “firing”/depolarizing, the QRS complex is the ventricles depolarizing (and the atria are depolarizing while this happens), and the T wave is the ventricles depolarizing. Depolarizing is when it contracts, and repolarizing is when it relaxes and refills.
Answer:
The answer: is eating a diet high in empty calories.
Explanation:
The other options will not cause cancer, this option potentially can.
