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..??

Absorption of Nutrients in Small Intestines

The digested food is now in simple form and is ready to use by cells. The inner wall of small intestines is called as Mucosa, it has numerous finger like projections called as Villi (singular- villus), which in-turn has finger like projections called as micro-villi. The purpose of villus is to provide large surface area for nutrient absorption. Villi have large network of blood capillaries, where the nutrients are absorbed in blood by diffusion.Most of the nutrients are absorbed in jejunum. except Iron is absorbed in duodenum vitamin B12 and bile salts are absorbed in the terminal ileum. Through blood digested food reaches to each and every cell of the body.

Photosynthesis for class 10th

● Photosynthesis ( Photo=Light) :-The biological process In which the plants synthesis their own food with the help of SunLight, Carbon Dioxide and water.It is the characteristic feature of plants. Photosynthesis takes place in the leaves of plants.where the sunlight is traped by green pigment chloroplast.Carbon Dioxide is taken from Atmosphere through Minute pore On leaves called stomata and water is absorbed by roots from soil and conducted to leaves through xylum to leaves. Oxygen is released after Respiration through stomata. Examine the below Diagram

Human excreatory system for class 10th

Excreation:- The process of removal of metabolic wastes from the body of an organism is called as Excreation. The full fludged system is concerned with the removal for metabolic wastes known as excreatory system. Here we will descuss Human excreatory system. In Human beings the excreatory organ is kidney. There are two kidneys in human beings, named as left and right kidney. These two kidneys filter the blood taking wastes out from the blood. The kindneys are bean shaped. Nephron is the structural and functional unit of kidney. Renal artery is a blood vessel which supplies blood to the kidney for filteration. The filtered blood is taken to the heart through Renal vein. Ureter:- Each kidney has a narrow, whitish, tubular struction about 25 to 30cm long called "Ureters" opening in a somewhat pear shaped muscular sac like structure called " Urinary Bladder" Ureters carry metablic waste "urine" from their respective kidneys to the Urinary...
