When an endocrine system organ functions abnormally, hormones aren’t released properly and target organs are affected. Choose an endocrine gland and a hormone it is supposed to release and then answer the following question: How would you explain the normal and abnormal functions of the gland you’ve chosen and its effect on target organs to a younger patient? Include at least one analogy in your answer.
Weegy: One of the endocrine glands is Hypothalamus. It releases thyrotropin and inhibiting hormones. Target organs, target tissues and target cells are those specific organs, tissues and cells upon which each hormone acts and produces its effects. [ The hypothalamus is a part of the brain situated just above the hypophysis. The pineal, hypothalamus, and pituitary glands respond to higher levels of vibration in the body. In our endocrine system-orchestra analogy, these organs would compose the soprano section. The pineal gland is also capable of effecting important brain structures, as it interconnects with the function of the nerve system. Like so many areas of the body, the endocrine system is such a complex system that much of its action remains a mystery. ] (More)

How long does it take for food to go through the digestive system?
Weegy: Digestion time varies between individuals and between men and women. After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. [ Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. In the 1980s, Mayo Clinic researchers measured digestion time in 21 healthy people. Total transit time, from eating to elimination in stool, averaged 53 hours (although that figure is a little overstated, because the markers used by the researchers passed more slowly through the stomach than actual food). The average transit time through just the large intestine (colon) was 40 hours, with significant difference between men and women: 33 hours for men, 47 hours for women. Two British doctors studied digestion time in children. They fed 35 children juice containing a red marker and asked the children's mothers to note when the stool first turned red. The mean time of transit from mouth to anus for the group was 33 hours (meaning half the children had digestion times slower than this and half had digestion times greater than this). ] (More)

How does digestion occur in the Large intestine?
Weegy: After all nutrients have been absorbed from ingested food during its passage through the small intestine, the watery waste passes into the large intestine. [ It is the final section of the gastrointestinal tract and its main function is to remove water (plus any remaining minerals) from the food waste and compress it into a form for easy expulsion from the body. As the chyme passes through the large intestine, the water is removed and the chyme is combined with mucus and bacteria (gut flora), and is converted into feces. ] (More)

How does digestion occur in the Mouth?
Weegy: INGESTION The entire digestive process begins with the mouth, where food and drinks are first be ingested through eating and drinking. advertisement MECHANICAL DIGESTION Mechanical digestion is the physical breakdown of food particles. [ Large pieces of food enter the mouth and must be broken down into smaller pieces to move through the remaining organs of the digestive system. An average adult human has 32 teeth, which perform a process called mastication, commonly known as chewing. The teeth rip and tear food into smaller pieces, preparing them for chemical digestion. The tongue also aids in mechanical digestion by moving food around in the mouth, placing it where the teeth can effectively grind it. CHEMICAL DIGESTION Although mechanical digestion is vital to the digestive process, it alone cannot break food down into molecules small enough for the body to use. Many of the organs in the digestive system secrete digestive juices which contain enzymes to perform chemical digestion. The mouth contains salivary glands, which secrete saliva, a fluid that contains mucus, water, electrolytes and enzymes. The presence of food triggers the secretion of saliva. The secretion is controlled by the autonomic nervous system- -an automatic system that regulates body functions. In addition to lubricating and binding the food, the enzymes in saliva initiate the breakdown of starches. Starchy foods are those that contain complex carbohydrates, such as rice, potatoes, wheat and corn. The enzyme alpha-amylase in saliva begins the process of breaking carbohydrates into the simple sugars the body can use. MOVEMENT Movement is an important digestive function that begins in the mouth. The tongue rolls food particles together and propels them toward the esophagus. This triggers the action of swallowing. As food is swallowed, the muscles lining the esophagus contract, creating a narrow section that pushes the food along the digestive tract. This movement, known as peristalsis, ... (More)

How does digestion occur in the small intestine?
Weegy: It's where the body takes the nutrients from your food into your system. Bile - emulsification of fat, Proteases - digestion of proteins, Lipase - digestion of fats, Nucleases - digestion of nucleotides, Amylase - digestion of starch. [ After it is digested, it can enter the small intestine via the villia of the enterocyte small intestinal cell. This is the process of absorption. So the main type of digestion taking place is chemical digestion. ] (More)
