Answer:
Method A is conduction and Method B is radiation.
Explanation:
Driving the situation in which the heat spreads through a "conductor". That is, although it is not in direct contact with the heat source, a body can modify its thermal energy if there is heat conduction by another body, or by another part of the same body. For example, while cooking something, if we leave a spoon against the pan, which is on the fire, after a while it will heat up too.
Heat is energy in transit. This energy is transported by means of electromagnetic waves in the infrared frequency. In the transmission of heat by radiation, this fact is more evident. All bodies emit radiation, just having a temperature. The only difference between light and heat is the frequency of radiation. Thermoses are a good example of thermal radiation. The walls of the thermos are double and silver. The double walls are separated by practically a vacuum, in such a way that the heat exchanges by conduction or convection are minimized, as they need a material medium to occur. The silver walls, on the other hand, minimize heat exchanges by radiation, thus making sure that the liquid inside the bottle does not lose or receive heat.
Answer:
1) Hiatal hernia is the disorder of this 26 year old business executive. Hiatal hernia occurs when upper part of stomach pushes through an opening in the diaphragm, and up into the chest. THis opening is called a esophageal hiatus or diaphragmatic hiatus. It is basically a protrusion of the upper part of stomach into the chest through a tear on the chest through a tear or weakness in the diaphragm. The patient presents with :
- Chest pain
- Severe hurtburn
- Abdominal pain
- Frequent burping
- Difficulty in swallowing
- Throat soreness
2) Adequate lower esophageal pressure at the lower esophageal sphincter normally prevent gastric reflux into the esophagus when lying down or bending over.
3) As M3 receptors (parasympathetic) are distributed at the lower esophageal sphincter, cholinergic agonist activates these receptors and increases contraction thus rsulting in a decrease in contraction and preventing Gastroesophageal reflux. Similarly the anticholinergic are avoided because they will relax the LES and thus GERD will increase.
4) H2 antagonists are recommended because they decrease the acid secretion especially at night by blocking H2 receptors.
5) Elevation of the head of the bed recommended in order to encourage the gravitational flows of the contents in stomach toward the pyloric end.
6) Normal Stomach pH = 3-5
Normal esophageal pH = 6-7
pH at Lower esophagus in gastroesophageal patient = 3-5
pH of stomach in patient of GERD = 3-5 (same as that in normal)
Sunflowers maintain homeostasis by using water. It's what they use to grow I guess.
Answer:
The <u>large intestine</u> is NOT an accessory organ of digestion
Explanation:
The accessory organs that make the process of digestion easier are:
- The liver produces bile continuously, a fluid that helps chemical digestion by emulsifying fats in the duodene. It helps digestion and fat absorption. If bile is immediately needed, it is released by the liver and goes straight to the intestine where it acts. If it is not needed immediately, it goes to the gallbladder.
- The gallbladder is an organ located under the liver that intervenes in food assimilation by the organism. Its main function is to store bile - the liquid produced by the liver to dissolve fats -. The liver produces bile and it reaches the gallbladder through the hepatic and cystic ducts, and it is stored in the gallbladder until it is needed. Whenever the stomach or intestine are digesting food, the gallbladder release the bile which flows through the cystic duct and the bile duct to the thin intestine. In fact, the secretion of bile by this organ is stimulated by food ingestion, especially by the ingestion of meat or fats.
- The pancreas secretes the pancreatic juice, composed of enzymes, water, bicarbonate, and electrolytes produced by acinar and epithelial cells. Secretory pancreatic cells are organized in sac-shape structures called acini. These structures are conformed of acinous cells and center-acinous cells that secrete digestive enzymes into the intestine The pancreatic juice flows along the principal pancreatic duct to the bile duct and from there to the small intestine. In the intestine, it degrades fats, carbohydrates, and proteins.
The large intestine is an organ directly involved in food digestion. It extends from the stomach to the anus and is in charge of the final process of digestion and resulting product absorption.
