The reason for tonic contraction in some sphincters of the digestive system . Introduction: Majority of the gastrointestinal tract is made up of continuous smooth muscles. These muscles have some group of cells which are connected electrically with the help of gap junctions. These cells create contracting segments. Different types of contractions can be seen in different regions of the tract. The contractions which sustain for a few minutes or several hours are known as tonic contractions.

Definition Definition Organ system that helps in the digestion of food by mechanical and biochemical processes. The digestive system breaks down food into simpler components that enable the body to then absorb or transport nutrients. The human digestive system includes the gastrointestinal tract or alimentary canal and the associate glands. The organs of the gastrointestinal tract include the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. The associated glands include salivary glands, liver, gallbladder, and pancreas.

Svp je voulais demander l aide pour mon exercice

Imagine that you are a clinical geneticist. Your colleague is an oncologist who wants your help explaining the basics of genetics to their patient, who will be undergoing genetic testing in the coming weeks for possible acute myeloid leukemia (AML) induced by the radiation she had several years ago for breast cancer. Write a 1,050- to 1,225-word memo to your colleague. Include the following in your memo: An explanation of the molecular structure of DNA and RNA, highlighting both similarities and differences A description of the processes of transcription and translation An explanation of the differences between leading and lagging strands and how the DNA is replicated in each strand Reponses to the following common questions patients might ask about this type of genetic testing and genetic disorder: Does AML run in families? What genes are tested for?

Respond to the following in a minimum of 175 words: What are some potential consequences that could result if the processes of replication, transcription, and translation don’t function correctly? Provide an example of how you might explain these consequences in terms that patients might understand.
