Food journey thorough the digestive system

Mouth:

This is where we ingest food. 

We do this by using our teeth.

Canine teeth stab and rip food.

incisors cut food.

Our molar grinds the food.

The salivary glands release saliva into the mouth.

saliva starts to break down sugars and lubricates the food.

Oesophagus:

A tube connecting the mouth to the stomach.

Food is pushed down to the stomach by the action of peristalsis.

Stomach

Our stomach churns food into a paste.

Some food gets broken down in the stomach.

Stomach acid kills bacteria.

Duodenum:

 This is the first part of the small intestine.

More chemicals are added in from the pancreas and Gall Bladder. 

Pancreas:

This adds a chemical into the duodenum to neutralise the stomach acid.

The pancreas also adds more chemicals into the duodenum to break down food.

Why do we have a mouth? 

To break do food.

What else does your mouth do?

Breaks down food by chewing 

I wonder.... English

I wonder when was the highlighter pens realeasd. It realeasd in 1910 and 1926. Here’s the history of highlighter pen.

The first one was Lee Newman’s felt-tip marker and second one Benjamin Paskach’s "fountain paintbrush a sponge-tipped handle with colors inside. But before Sharpie appeared Sidney Rosenthal invented and started selling in 1953 a Magic Marker. The first predecessor of a highlighter was invented by a Japanese inventor Yukio Horie of the Tokyo Stationery Company, who developed in 1962 the first felt-tip pen that used water-based ink. It was not made to highlight texts, but it inspired Carter’s Ink Company to, in 1963, start manufacturing similar water-based Marker with translucent ink. It was sold under the name Hi-Liter, and it worked on capillary action.

Plant kingdom

The Five Kingdom

 

- Bacteria

Single-celled organism without a nucleus.

- Protoctista

A single-celled organism with a nucleus.

- Fungi

Multi-celled with cell walls but cannot -carry out photosynthesis.

- Plants

Multi-cellular with cell walls and can carry out photosynthesis.

- Animals

Multi-cellular with no cell walls.

The Kingdoms are subdivided into phyla, then classes, orders, families, genera, and species. The smallest classification contains only one type of organism, a species. A species is defined as a group of the similar organism capable of breeding with each other and producing fertile offspring.Plant - Organism that produces their own food by the process of photosynthesis.Vascular system - The vessels and tissue that carry or circulate fluids.Seeds - Embroyonic plant enclosed in a covering called the testa and usually contains some stored food.Spores - A reproductive unit capable of developing into another such plant without sexual fusionFlowers - The reproductive organs of some plants that are typically surrounded by brightly colored petals.Cones - A woody reproductive structure that contains seeds.Sexual fusion - Reproduction involving the combining of a male (sperm) and female (egg) gametes.

The Animal Kingdom

The animal kingdom is divided into two phyla - vertebrates and invertebrates.
