Study Notes
- The lesson covers animal nutrition and digestive organ systems.
- Three learning outcomes are: identifying nutrients animals seek out, comparing digestive system evolution across phyla, and describing the mammalian digestive system.
- Animals require organic molecules for chemical energy and carbon, obtained from carbohydrates, lipids, and proteins.
- Essential nutrients include essential amino acids, which humans cannot synthesize from other nutrients.
- Essential fatty acids, like omega-3 and omega-6, are important for phospholipids in cells and cognitive function.
- Vitamins are essential nutrients that play important roles in cellular respiration and energy metabolism.
- Minerals are the only essential inorganic nutrients.
- Sponges lack a digestive system and digest food intracellularly.
- One-way digestive systems have a gastrovascular cavity for digestion, absorption, and elimination.
- Two-way digestive systems have specialized compartments for mechanical and chemical digestion.
- The oral cavity, pharynx, and esophagus are involved in the two-way digestive system of mammals.
- The stomach uses smooth muscle tissue for peristalsis and has accessory glands for chemical digestion.1. Pepsinogen becomes pepsin to digest proteins.
- Pepsin accelerates the conversion of pepsinogen to pepsin.
- Positive feedback mechanism is initiated by the presence of proteins in the stomach.
- Chyme moves from the stomach to the small intestine.
- Small intestine has a finger-like jungle architecture for nutrient absorption.
- Chemical digestion in the small intestine includes the breakdown of polysaccharides, disaccharides, and proteins.
- Bile emulsifies fat for digestion and absorption.
- Water-soluble nutrients and short-chain fatty acids cross into blood capillaries.
- Long-chain fatty acids are absorbed by chylomicrons.
- Chylomicrons are too big for blood capillaries and enter the lacteal vessel for transport through the lymphatic system.
