Why does the transfer of carbon and oxygen take place

Biology
2 answers:
Elza [17]3 years ago
5 0

The transfer of the  carbon-dioxide and oxygen occurs during the process of the respiration. The oxygen from the air we breathe in our lungs is diffused into the blood present in the capillaries surrounding the alveloi of the lungs. The carbon-dioxide is diffused into the lungs, which is then breathed out. This transfer of the gases is necessary as the oxygen is required by the body to break down the fatty acids and other components in order to release energy for different processes of the body. The carbon-dioxide released after the generation of the energy is eliminated from the body by this exchange.

The digestive tract is essentially one long tube. Write down order of the structures
Angelina_Jolie [31]

Answer:

It consists of the mouth, or oral cavity, with its teeth, for grinding the food, and its tongue, which serves to knead food and mix it with saliva; the throat, or pharynx; the esophagus; the stomach; the small intestine, consisting of the duodenum, the jejunum, and the ileum; and the large intestine, consisting of the cecum, a closed-end sac connecting with the ileum, the ascending colon, the transverse colon, the descending colon, and the sigmoid colon, which terminates in the rectum. Glands contributing digestive juices include the salivary glands, the gastric glands in the stomach lining, the pancreas, and the liver and its adjuncts—the gallbladder and bile ducts. All of these organs and glands contribute to the physical and chemical breaking down of ingested food and to the eventual elimination of nondigestible wastes.
