Human digestive system consists of a group of organ working together, the food which we intake all the organs work together to break the food and convert it into energy and different types of nutrients. The food we intake is digested and all the useful nutrients and energy is used by the body and remaining is related out of the body as by product.

It s a sum of gastrointestinal tract GIT which is also known as Alimentary canal, accessory organs. Breaking down of food is done with the help of accessory gland which is not a part of GIT, it realises enzymes.

Here is how human digestive system works:

1. Mouth – the journey of the food starts from here. Each organ present in our body contributes in digestion. Including teeth, saliva, etc. Initially the food is broken down into tiny tiny pices with the help of teeth.

2. Oesophagus or food pipe – This chewed and the broken down food enters our body with the help of food pipe. It travels down to the stomach.

3. Stomach- It is sack like thing which stores the food. It consists of HLC acid which helps in breaking down of the food. If there is any microorganism present in our food hoc acid helps to kill the one. Then it travels to Small Intestine.

4. Small Intestine- It is a tube like structure which is 10 feet long and is located in our lower part of our body, just behind the stomach. The process of digestion ends here. Then it travels to large intestine.

5. Large intestine- The main function of this gland is to absorb the the remaining water in the food which in undigested. It enables bacterial fermentation of the undigested food. It is also a thick tube like structure which is located with small intestine.

Everything in Earth’s framework can be put into one of four significant subsystems: land, water, living things, and air. All of these together are further know as lithosphere, hydrosphere, biosphere, and atmosphere. All of these are equally important and have their own relevance.

Lithosphere:

It is accepted the lithosphere advanced about 4.6 billion years prior. The lithosphere alludes to the strong, rough & rocky crust outside that covers the whole planet. This strong, rough outside layer is made out of various rocks that have been rouped into three classes dependent on how they have formed their shape. The different types of rocks are Metamorphic rocks, Sedimentary rocks and Igneous rocks.

The lithosphere incorporates a different number of various landforms like mountains, valleys, rocks, minerals and soil. The lithosphere is continually changing because of powers and pressing factors like the sun, wind, ice, water and synthetic changes. The Earth’s surface is made into two kinds out of lithospheres. They are known as the “maritime and mainland lithospheres”.

The oceanic lithosphere incorporates the highest layers of mantle which is finished off with a slight yet substantial oceanic crust. The hydrosphere and lithosphere meet at this place. The continental lithosphere incorporate the highest layers of mantle which is finished off with a thick yet light continental crust. Here Atmosphere, hydrosphere and biosphere meets.

Hydrosphere:

In hydrosphere, the main asset is water. The hydrosphere consists of all form of water that is present in Earth’s surface. The types of water incorporate things like the sea, lakes, streams, snow and ice sheets, water under the earth’s surface and surprisingly the water fume that is found in the environment. The hydrosphere is consistently in motion as seen through the development and stream of water in waterways, streams and the (sea shore). Plants and living creatures beings depend on the hydrosphere for their endurance as water is fundamentally very important to survive.
