Study Notes
- A tissue is a group of cells with similar structure and function.
- An organ is a group of tissues working together for a specific function.
- The stomach is an example of an organ, containing muscle and glandular tissues.
- Organs are part of organ systems, which work together to form organisms.
- The digestive system is an organ system, responsible for breaking down food into nutrients.
- Human digestive system consists of mouth, esophagus, stomach, small intestine, large intestine, and anus.
- Food is initially chewed in the mouth and saliva begins the process of digestion.
- Stomach secretes hydrochloric acid and digestive enzymes to break down food.
- Small intestine absorbs digested nutrients into the bloodstream, with help from enzymes from liver and pancreas.
- Bile from the liver speeds up the digestion of lipids and neutralizes stomach acid.
- Feces is formed in the large intestine and eliminated from the body.
- Carbohydrates, proteins, and lipids are the main nutrients in food, which are larger than the molecules that can be absorbed into the bloodstream and need to be digested.
- Digestive enzymes break down large food molecules into smaller ones.
- Absorption of nutrients occurs in the small intestine through diffusion or active transport.
- Products of digestion, such as glucose, are used by the body for energy and building new macromolecules.
