1. Ingestion

Welcome 6th graders!

A journey soon begin through Social Science experiences!

2. Swallowing

Once you've chewed your food and it's mixed with saliva, you swallow it. The food travels down your esophagus, a muscular tube, to your stomach.

3. Stomach

4. Small intestine

The partially digested food moves into the small intestine, where bile from the liver and enzymes from the pancreas and intestinal walls continue breaking down the food. Here, nutrients are absorbed into the bloodstream to provide energy for your body.

Fun facts!

- The human digestive system is like a long, twisty tube that's around 30 feet (9 meters) long in adults! - Your stomach produces hydrochloric acid, which is strong enough to dissolve some metals. - The small intestine is where most of the digestion and absorption of nutrients take place.

SC.6.L.14.1Describe and identify patterns in the hierarchical organization of organisms from atoms to molecules and cells to tissues to organs to organ systems to organisms. - SC.6.L.14.2 Investigate and explain the components of the scientific theory of cells (cell theory): all organisms are composed of cells (single-celled or multi-cellular), all cells come from pre-existing cells, and cells are the basic unit of life. -SC.6.L.14.3 Recognize and explore how cells of all organisms undergo similar processes to maintain homeostasis, including extracting energy from food, getting rid of waste, and reproducing. -SC.6.L.14.4 Compare and contrast the structure and function of major organelles of plant and animal cells, including cell wall, cell membrane, nucleus, cytoplasm, chloroplasts, mitochondria, and vacuoles. -SC.6.L.14.5 Identify and investigate the general functions of the major systems of the human body (digestive, respiratory, circulatory, reproductive, excretory, immune, nervous, and musculoskeletal) and describe ways these systems interact with each other to maintain homeostasis. -SC.6.L.14.6 Compare and contrast types of infectious agents that may infect the human body, including viruses, bacteria, fungi, and parasite.
