Digestion process for class 10th

The semi-digested food from stomuch chyme enters into small intestines, where complete digestion of chyme takes place by the action of more enzymes and juices.Small intestines are divided into three parts
1. Duodenum -- forms the first section of Small intestine. Pancreas and liver are connected to this region.These two organs release their juices i.e digestive enzymes and bile respectively. Trypsinogen  and chymotrysinogen are the digestive enzymes released into the duodenum.

2.The jejunum-- is the middle section of small intestines.It is responsible for the absorption of
nutrients from the digested food.

3.Ileum ---is the last section of small intestines and is connected to the large intestines. This section absorbs the nutrients which were not absorbed by Jejunum.

The waste material enters into the large intestine where excessive water is absorbed.

Waste material gets collected in a bag like structure called Rectum and than this waste material is thrown out from the body through Anus.

 In the next post we will disscuss how nutients are absorbed in the small intestines...??

Question for you..... 1.The semi-  digested food is called as .........??

2.Name the two enzymes released in Duodenum..??

Male reproductive system

Reproduction In Human Beings Reproduction:- It is the biological process in which organisms give offspring for the continuity of race. A complete system is concerned to perform this function called reproductive system. Here we are going to discuss sexual reproduction in Human Beings. As we human beings are diocious i.e male and female sexes are separate Male reproductive system in Human Beings. Testis:- These are the primary sex organs of males, testis produce male sex cells (sperms) as well as male sex hormone testosterone. Testis lie out side the body between the lungs in a muscular pouch called Scrotum.Scrotum maintains the temperature of testis which is below 3℃ than body temperature. Testis are two in number. Alongside the testicles are the  epididymis   and the  vas deferens.  which make up the duct system of the male reproductive organs. The vas deferens is a muscular tube that passes upward alongside the testicles and transports the sperm-...

Structure and function of Neuron

Neurons (nerve cells) are the functional units of the nervous system.  A typical neuron is divided into three parts i.e Cell body or Soma,Some contains all the cell organelles like Nucleus, Mitochondria etc. Dendrites and Axon. Schwann cells of Axon are covered by Myelin Sheath. Dendrites are branched like structures on Soma. Axon terminal is also branched like structure. The signals are received from neuron by dendrites and are send to next neuron bye chemo-electrical impulses through axon. The junction between the two cells is known as Synapses.In neuron signal travels in the form of chemicals but at synapses in changes in to electrical impulses.
