Digestion and respiration systems, anatomy and physiology

Nutrition process: 1º [blank_start]Obtaining[blank_end]. We obtain nutrients from the digestive system and oxygen form the respiratory system. 2º [blank_start]Distributing[blank_end]. In this phase, we use the circulatory system. 3º [blank_start]Eliminating[blank_end]. We have to eliminate waste products, via the excretory system and sweat glands and carbon dioxide via the respiratory system.

[blank_start]Ingestion[blank_end]. Is the process in which we intake food [blank_start]Absorption[blank_end]. Is when we transfer nutrients from the digestive tract into the blood. [blank_start]Digestion[blank_end]. Is composed of 2 processes, mechanical and chemical. Egestion. Is the elimination of substances that can't be absorbed.

Accessory glands [blank_start]secrete substances[blank_end] into the [blank_start]digestive tract[blank_end].

Name the parts of the digestive system.

[blank_start]Epiglottis[blank_end] stops food from entering the respiratory system. [blank_start]Cardias[blank_end] and [blank_start]pylorus[blank_end] are the 2 sphincters that the stomach has. The [blank_start]hepatocytes[blank_end] are the small ducts of the liver that collect its bile. [blank_start]Gallbladder[blank_end] pear-shaped. The small intestine is divided into 3 parts: the [blank_start]duodenum[blank_end], [blank_start]jejunum[blank_end] and [blank_start]ileum[blank_end]. This part of the digestive system doesn't have villi, instead, it has lubricating mucus. [blank_start]Large intestine[blank_end].
