The first organ that receives nutrients from the small intestine is the liver. To better understand this, check out the process flow of the digestive system up to how the liver becomes the first organ to benefit from the nutrient absorption by the small intestines. 1. Esophagus - After chewing, the food is pushed down the esophagus and then out of the esophageal sphincter, which is a ring-like muscle at the junction of the esophagus and stomach that controls the passage of food and liquid between the esophagus and stomach.2. Stomach - Swallowed food and liquid are stored in the stomach. The stomach then mixes the food and liquid with digestive juices that it produces. The mixed food and gastric juices will then be called chyme. The chyme is then slowly emptied into the small intestine. 3. Small intestine - The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine and push the mixture forward to help with further digestion. The small intestine has multiple parts: the duodenum, the jejunum and the ileum. The ileum mix and push food towards the large intestines. Located within the ileum are villi that increase the surface area for absorption. The nutrients absorbed here are transferred to the blood stream and liver.
The correct answer is A: adaptive radiation
<span>The correct answer is 'metastasis'. This is the migration of cancer cells from one place to another in the body. They do this by travelling through the blood stream or the lymphatic system.
Mitosis is the process of asexual cell division. It produces cells that are identical to the original cell as one cell divides into two after replicating its organelles and genetic information. (Mitosis makes my toes.)
Apoptosis is controlled cell death. When cells are getting old then they need to be replaced. Old cells are programmed to 'die' at the correct time. The cell contents are recycled to make new cells.</span>
