Human Digestive System
The digestive system consists of the alimentary canal and accessory organs. The alimentary canal extends from the mouth to the anus. Accessory organs that aid digestion include the salivary glands, liver, gallbladder and pancreas. Food is broken down mechanically and chemically by these organs as it moves through the digestive tract, with nutrients being absorbed in the small intestine and waste expelled from the anus.
Human digestive sytem
The human digestive system breaks down food into smaller components that can be absorbed into the bloodstream through a complex series of organs and glands. Digestion involves both mechanical and chemical breakdown of food. The accessory organs that aid in digestion include the salivary glands, teeth, pancreas, liver, and gallbladder. Food travels through the esophagus, stomach, small intestine, large intestine, and exits through the anus, with different organs contributing mechanical and chemical digestion along the way.

Your liver
The liver is the largest internal organ, located in the upper right abdomen. It performs over 200 functions including storing nutrients, secreting bile, and synthesizing proteins and cholesterol. The liver creates bile which is composed of water, ions, bile acids, and organic molecules. Bile emulsifies fats during digestion so they can be absorbed by the small intestine. The liver also processes waste from red blood cell breakdown and other metabolic activities.
Accessory organs of digestive system
The pancreas produces enzymes and hormones that aid digestion. It releases enzymes into the small intestine through the pancreatic duct to break down proteins, carbohydrates, and fats. It also produces the hormones insulin and glucagon, which regulate blood sugar levels. Problems can occur if the pancreas fails to produce enough enzymes, leading to malnutrition, or fails to produce enough insulin, resulting in diabetes.

Human digestive system
The document summarizes the human digestive system in 8 steps:
1) Mouth and esophagus where food is ingested and moved to the stomach through peristalsis.
2) Stomach which secretes gastric juices and enzymes like pepsin to break down proteins.
3) Small intestine which receives secretions from the liver and pancreas that further digest food, and intestinal villi which absorb the digested nutrients.
4) Large intestine where water is absorbed and remaining waste is sent to the rectum.
5) Rectum and anus where undigested waste is stored and expelled.
Digestive system of humans
The digestive system begins with the mouth, which includes the oral cavity, tongue, jaw, and throat. Food then passes into the esophagus and enters the stomach. In the stomach, food is churned with gastric juices containing hydrochloric acid and enzymes. The partly digested food then moves into the small intestine, where it is further broken down by enzymes from the liver, pancreas, and intestinal walls. The digested food is then absorbed into the bloodstream and transported throughout the body. Undigested waste moves into the large intestine to absorb remaining water and salts before being excreted as feces through the anus.
Digestive system presentation
The digestive system breaks down food and extracts nutrients and energy. It starts in the mouth, where food is chewed and broken down. The esophagus then transports the food to the stomach for further digestion. The small intestine, which is over 20 feet long, further breaks down food particles. The large intestine then moves waste to the rectum before it is expelled through the anus. The entire digestive process takes around 3 hours.
Digestive system powerpoint
The digestive system breaks down food and turns it into energy. Digestion begins in the mouth through chewing and the release of enzymes. Swallowed food then passes through the esophagus into the stomach, where it is stored, mixed with acids, and further broken down. The partially digested food then moves into the small intestine, where most digestion and absorption of nutrients occurs, before exiting the body through the large intestine and anus.
Digestive system
The digestive system breaks down food into smaller molecules through mechanical and chemical digestion. Mechanical digestion involves chewing and churning of food, while chemical digestion uses enzymes to break down food molecules.

Human Digestive System
The digestive system of the human body comprises a group of organs working together to convert food into energy for the body. Human Digestive System and Nutrition involve the intake of food by an organism and its utilization for energy. This is a vital process which helps living beings to obtain their energy from various sources. The food which we eat undergoes much processing before the nutrients present in them are utilized to generate energy. This processing is known as digestion. The digestion process involves the alimentary canal along with various accessory organs and organ systems. In humans, the process is quite simple due to our monogastric nature. This means that we have a one-chambered stomach, unlike other animals such as cows, which have four chambers.

This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

human digestive system ppt powerpoint presentation (19 slides) /In English/format-powerpoint presentation(.ppt)
- 2. WHAT is DIGESTION ?? Carbohydrates Proteins Vitamins Fats Mineral Absorbed by body Excreted out from body
- 4. 3 layers of digestive system
- 5. MOUTH
- 6. Salivary Glands • Saliva consists of 1. Water (98.5- 99%) 2. Ptyalin (1-1.5%) 3. 1.5 l produced in 24 hrs Converts Starch Glucose
- 7. Tongue
- 9. Esophagus • Approximately 25 cm long. • Functions include: 1. Secrete mucus 2. Moves food from the throat to the stomach using muscle movement called peristalsis • If acid from the stomach gets in here that’s heartburn.
