L' APPARATO DIGERENTE

bocca-faringe

Il cibo viene trasformato per ricavare i nutrienti . L' alimentazione serve agli oranismi per ottenere i nutrienti , che sono indispensabili per tre funzioni principali : fornire energia, permettere la costruzione e il rinnovamento delle strutture del corpo, fornire sostanze essenziali che l' organismo non è in grado di produrre da solo. In base alla dieta , gli animali si distinguono in: ERBIVORI che mangiano piante CARNIVORI che si nutrono di altri animali ONNIVORI che mangiano sia piante che animali.

esofago
fegato
stomaco
intestino tenue
intestino crasso
ano

PROCESSO DI TRAFSORMAZIONE DEL CIBO

Il processo di trasformazione del cibo avviene in diverse fasi. La prima è L'INGESTIONE, cioè l' introduzione del cibo nell' organismo. Segue la DIGESTIONE, che consiste nella demolizione del cibo prima in modo meccanico, attraverso la masticazione, e poi in modo chimico, grazie agli enzimi digestivi.

La digestione è necessaria perchè gli alimenti contengono macromolecole come proteine, lipidi e carboidrati, che sono troppo grandi per entrare nella cellula e non sono direttamente utilizzabili. Per questo vengono scomposte in molecole più semplici: Le proteine in amminoacidi, i carboidrati in monosaccaridi e i lipidi in acidi grassi e glicerolo.

PROCESSO DI TRAFSORMAZIONE DEL CIBO

In questo modo le molecole semplici possono essere assorbite e utilizzate dalle cellule per produrre energia e costruire le strrutture dell' organismo.Dopo la digestione ci sono altre due fasi: ASSORBIMENTO ED ELIMINAZIONE. Nell' assorbimento, le sostanze semplici ottenute dalla digestione come amminoacidi e zuccheri,passano dal tubo digerente al sangue e arrivano alle cellule. Nell' eliminazione, le parti di cibo che non sono state digerite vengono espulse attraverso le feci.

il percorso del cibo

Il cibo sgue un percorso: bocca- faringe-esofago- stomaco- intestino tenue- intestino crasso e ano.L'apparato digerente è formato dal tubo digerente e da alcune ghiandole accessorie. Esse sono: ghiandole salivari, fegato e pancreas. Queste producono succhi digestivi che aiutano a digerire il cibo. Il fegato produce la bile, che viene conservata nella cistifellea. Il tubo digerente è un lungo canale formato da vari organi. Nella bocca il cibo viene masticato e mescolato con la saliva, passa nella faringe e nell' esofago , arriva allo stomaco dove inizia la digestione chimica. Va poi nell' intestino tenue, dove si completa la digestione e avviene l' assorbimento nell' intestino crasso viene riassorbita l'acqua . Infine i residui vengono eliminati attraverso l' ano.

CARDIAS E PILORO

Nel tubo digerente ,sono presenti degli sfinteri , cioè anelli muscolari che regolano il passaggio del cibo.Il cardias tra esofago e stomaco il piloro (sfintere pilorico) tra stomaco e inestino. Questi servono a controllare il passaggio del cibo e a evitare che torni indietro.

LA SALIVA

La salive è prodotta dalle ghiandole salivari : parotidi, sottomandbolari e sottolinguarisvolge diverse funzioni importanti, lubrifica il cibo facilitando la deglutizione, protegge la bocca, neutralizza gli acidi e ha un' anazione antibatterica grazie all' isozima nella saliva è presente un' enzima chiamato amilasi salivare (o ptalina), che avvia la digestione dell' amido, trasformandolo in maltosioe destrine . la sua azione continua per un breve tempo anche dopo la deglutizione, ma viene poi bloccata nello stomaco

LA MASTICAZIONE

Un adulto ha 32 denti (16 sopra e 16 sotto),divisi in quattro tipi:INCISIVI: a forma di scalpello per mordere e tagliare. CANINI: utili per lacerare il cibo MOLARI-PREMOLARI: larghi e piatti per tritare il cibo.
I bambini invece hanno i denti da latte, che sono solo 20 e vengono sostituiti tra i 6 e i 9 anni.

Presentation WOW

Boring Presentation

You know a presentation is WOW when you keep your audience's attention, everyone assimilates the information you have shared, you turn interactivity and animation into allies, and you hear the applause from the audience.

You know a presentation is boring when you see that drowsiness takes over your audience, no one has understood anything you've said, you hear snores from your audience, and there's so much text that not even an image fits.

Use tables and infographics

Statistics convey professionalism and a greater sense of accuracy.An additional tip: always try to include the source.

CONCLUSIONS

A great presentation is clear and structured in order to transmit information in an orderly and hierarchical way, and to convey engaging content to the brain. Animation and interactivity are two fundamental pillars for this purpose. Tags, windows, links, audios... With Genially, you can include any type of interactivity to add additional content and provide it with an animation in order to capture the attention of your audience.

What you are reading: interactivity and animation can make even the most boring content fun. At Genially, we use AI (Awesome Interactivity) in all our designs, so you can level up with interactivity and turn your content into something that adds value and engages. Need more reasons to create dynamic content? Well, 90% of the information we assimilate comes to us through sight, and we also retain 42% more information when the content moves.

With Genially templates, you can include visual resources to leave your audience speechless. Also, highlight a specific phrase or data that will be etched in the memory of your audience and even embed external content that surprises: videos, photos, audios... Whatever you want! Interactivity and animation can be your best allies when creating tables, infographics, or graphics that help provide context to the information and simplify the data to convey it to your audience. We are visual beings and find it easier to 'read' images than to read written text.

IL DENTE

Se guardiamo un dente da vicino vediamo tre parti principali: LA CORONA(la parte bainca esterna) IL COLLETTO(la zona di passaggio) LA RADICE(conficcata nell'osso). Fuori è protetto dallo SMALTO che è la sostanza più dura del nostro corpo, mentre dentro c'è la DENTINA. Al centro troviamo la POLPA, dove passano i nervi.
