What are the parts of the digestive system tbrough which food passes?

What are the parts of the digestive system tbrough which food passes?

Parts of GI system: The GI system start with the mouth and teeth. This is where digestion begins. The food is the swallowed and taken to the stomach via the esophagus. In the stomach food is exposed to acid and mechanical grinding. Food then passes into the duodenum, jejunum and ileum where nutrients are absorbed. The liquid then enters the colon where water is absorbed and then out through the anus. ...Read more

If the immune system mediated an aggressive attack on the whole peripheral nervous system and killed the entire nerves of the body what are symptoms ?

If the immune system mediated an aggressive attack on the whole peripheral nervous system and killed the entire nerves of the body what are symptoms ?

Death: Although i just answered your question, important to understand that this would involve a rare progressive irreversible anaphylactic allergic reaction, and this really affects numerous organ systems. However, consider that there are chronic immune disorders that attack peripheral nerves (cidp), and nerves in central brain and spinal cord (ms). This is almost never an all or none situation. ...Read more

Significance of this? Extrinsic compression on the thoracic esophagus by the aortic arch in what appears to be left main stem bronchus.

Significance of this? Extrinsic compression on the thoracic esophagus by the aortic arch in what appears to be left main stem bronchus.

Odd: I assume you are reading the results of a radiology study (recent imaging procedure). The listed structures all lie in close proximity in the mediastinum, the most posterior of which is the esophagus. Unless you are having difficulty swallowing, a cough, or chest discomfort, I wouldn't worry much about this. You might want to confirm by reviewing the report with your doctor. ...Read more

What is the function of the extra domain in IgE & igm?

What is the function of the extra domain in IgE & igm?

Trick question: Are you studying immunology? The extra domain on ige indicates a unique role for the c2 domain in the interaction between ige and fcri. C2 reduces the off-rate of the ige/fcri, thereby resulting in a more stable complex. It is felt that the domain on igm co-contributes to the pentamic structure production. ...Read more

What are the branches of immunology?

What are the branches of immunology?

Innate and Adaptive: Innate immune cells such as neutrophils are our first-line defense and this type of immune system is found in most animals. Adaptive immune cells, such as T and B cells are able to become "memory" cells that allow us to build up immunity to viruses and bacteria that challenge us and try to attack us again. Vaccines help to boost our adaptive immunity so that we have a leg up on infections. ...Read more

List the cranial nerves: signify each of the nerves function, which ones have parasympathic innervation, which ones are involved in smell, sight, auditin?

The cranial nerves: I controls smell; ii vision; iii, iv, and vi all control eye movement; v controls part of the face sensory and muscle; vii is the main facial nerve and controls facial movements; viii is the auditory and vestibular (balance) nerve; xi controls part of the throat & tongue; x controls the gag reflex and parasympathetic function; xi controls the large strap muscle on the side of the neck; xii tongue. ...Read more

If some of the steroid/anesthetic of epidurals coated the nerves that innervate the l intestine or other organs, could gastric stasis result?

If some of the steroid/anesthetic of epidurals coated the nerves that innervate the l intestine or other organs, could gastric stasis result?

Epidurals and ileus: Nerves innervating the large intestine arise from the mid thorax and so a lumbar epidural steroid injection i unlikely to affect those nerves. Even if some did get distributed, it would result in better GI motility. ...Read more

What's the difference between hypersensitivity and auto-immune disease, in the terms of immunology?

What's the difference between hypersensitivity and auto-immune disease, in the terms of immunology?

Very different: A hypersensitivity is generally what we call an allergic reaction. This is mostly to things you find in the environment, and most of the time is driven by an antibody called ige. An autoimmune disease is usually driven by igg antibody, and what is being attacked is something in the body that the immune system thinks is "foreign" and should be "dealt with" when it shouldn't be. ...Read more

Which part of the nervous system is control by 75% of the vagus nerve?

Which part of the nervous system is control by 75% of the vagus nerve?

Please clarify: Frankly, I have no idea what your post means. The vagus nerve is PART of the nervous system. It's part of the parasympathetic nervous system. Maybe if you posted what led you to ask the question I could figure out what you mean because right now I haven't got a clue. It's like asking, "Which part of the car is control by 75% of the windshield?" ...Read more
