Digestion presentation
Digestion is the process by which food is broken down into smaller units that can be absorbed and used by the body. It takes place along the gastro-intestinal tract, which begins in the mouth and proceeds through the esophagus, stomach, small intestine, and large intestine before waste is excreted through the rectum. Digestion begins as food is broken down mechanically by teeth and through enzymes in saliva in the mouth, and then further broken down by gastric juices in the stomach and enzymes in the small intestine where nutrients are absorbed before passing to the large intestine.
Digestive System
The digestive system breaks down food into smaller components that can be absorbed and used by the body. It consists of the mouth, esophagus, stomach, small intestine, large intestine, and anus. In the mouth, teeth grind food and saliva begins breaking down starches. The esophagus transports food to the stomach through peristalsis. The stomach further breaks down food through churning and acid. Nutrients are then absorbed in the small intestine through enzymes and villi. The large intestine absorbs water before waste is expelled from the anus.

Digestive system of human body
The digestive system breaks down food into nutrients through four main stages: ingestion, digestion, absorption, and egestion. It includes the mouth, esophagus, stomach, small intestine, large intestine, liver, and salivary glands. Food is ingested, broken down by teeth and saliva in the mouth, and passed through the esophagus to the stomach for further digestion. Nutrients are then absorbed in the small intestine before waste is eliminated in the large intestine and rectum.
Digestive system
The digestive system breaks down food through a multi-step process. Food is chewed in the mouth and further broken down by stomach acid before entering the small intestine, where most digestion and nutrient absorption occurs. The large intestine removes water from waste before it is stored in the rectum and excreted through the anus. Key organs that aid digestion include the mouth, esophagus, stomach, pancreas, liver, gallbladder and intestines.

Living Things and Non-Living Things
This is a presentation I use with my students to begin to inquire into what are the characteristics of life.
Inferences And Predictions
A slideshow creating for a middle school science class. Students will look at the images and make inferences or predictions.
Student Voice Presentation
When students have a voice and are able to communicate, collaborate, and create using tools like blogs, wikis, podcasts, and social networks, it allows them to build their own understanding and educate themselves. Giving students ownership over their learning and a real audience empowers them to construct their own meaning. When students have a voice, it changes education from a teacher-centered model to one where students work to develop their knowledge.
Evolution
Evolution occurs when there is genetic variation between individuals within a species, competition for limited resources, and differential survival and reproduction. For evolution to happen, both individuals and the environment must change over time, as no change would result in no evolution. The main sources of change are overproduction of offspring, genetic variation between individuals, competition within a species for scarce resources, and differences in survival and reproduction with the most fit individuals passing on their genes.
The Living Environment: Regents Preparation

It also provides some helpful review website links for additional preparation resources.
Embryonic Development
A presentation (prepared by middle school life science students) on the process of embryonic development.
Asexual Reproduction
Asexual reproduction allows organisms to reproduce without combining genetic material from two parents. There are several types of asexual reproduction including binary fission in single-celled organisms, budding in hydra and yeast where new individuals pop out of the parent, spore formation in plants, algae and fungi, and vegetative reproduction in plants through runners, rhizomes, tubers, bulbs or grafting to form new individuals without seeds or spores.
Cell Organelle Review
The document provides an overview of the major organelles found within cells, including the cell membrane, ribosomes, cell wall, cytoplasm, chloroplasts, vacuole, lysosomes, nucleus, endoplasmic reticulum, mitochondria, Golgi body, centrioles, and chromosomes.

It discusses neurons in the nervous system, salivary glands in the digestive system, nasal cells in the respiratory system, muscle cells in the skeletal-muscular system, kidney cells in the excretory system, artery and vein cells in the circulatory system, pancreas and adrenal gland cells in the endocrine system, white blood cells and their role in attacking anthrax in the immune system. Links to images are provided for each cell type.
Body Systems Presentation
The document outlines several human body systems including the circulatory, endocrine, immune, excretory, skeletal muscular, and respiratory systems. The circulatory system transports oxygenated and deoxygenated blood through the heart, arteries, veins and capillaries. The endocrine system regulates the body through glands and hormones. The immune system protects the body through antigens, antibodies, and macrophages. The excretory system removes waste from the body using the kidneys, ureters, bladder and skin. The skeletal muscular system provides structure, movement and protection using bones, muscles, cartilage and joints. The respiratory system intakes and exchanges gases using the nasal cavity, pharynx, larynx, trachea, bron

Ardito Digestive System Review
- 1. THE DIGESTIVE SYSTEM A Study Guide Mr. Ardito’s Living Environment
- 2. The purpose of the Digestive System To make big things into small things
- 3. The Parts of the Digestive System
- 4. The Mouth Teeth grind food into swallowable substance (bolus) Enzymes in saliva start to break down starches.
- 5. Esophagus Muscular contractions move the bolus to the stomach These contractions are called peristalsis No new digestion occurs
- 6. Stomach Stomach is very muscular and churns the food into a paste (chyme). Stomach makes acid which helps break down proteins.
- 7. Small Intestine No new mechanical digestion takes place. Enzymes break down proteins, starches, and fats Nutrients are absorbed into the bloodstream via the villi.
- 8. Large Intestine Undigested food (now called feces)passes into the large intestine. Water, minerals, and vitamins are reabsorbed.
- 9. Anus/Rectum The rectum stores feces until it is ready to be released. The anus is the opening through which feces is released.
- 10. Types of Digestion Part Mechanical Chemical Enzymes from Mouth Chewing saliva None (still Esophagus None continuing from mouth) Acid from gastric Stomach Churning of Food juice Small Intestine None Enzymes Reabsorption of Large Intestine None water and minerals
- 11. Enzymes Enzymes are chemicals that speed up chemical reactions. Enzymes used in digestion help break big things into small things. 3 types of enzymes Proteases - act on proteins Amylases - act on starch Lipases - act on fats
