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:
Atrial flutter is a type of abnormal heart rhythm, or arrhythmia. It occurs when a short circuit in the heart causes the upper chambers (atria) to pump very rapidly. Atrial flutter is important not only because of its symptoms but because it can cause a stroke that may result in permanent disability or death.
Answer: True
Explanation:
The cardiovascular system includes the heart and blood vessels. The function of the heart is to pump out oxygenated blood via blood vessels to all the parts of the body. The blood vessels arteries, veins and capillaries contribute to the transfer and distribution of the blood.
