Study Notes
Nutritional Classes and Sources
- Bread, cereals, and desserts are typically high in carbohydrates.
- Foods primarily made of sugars or starches are also high in carbohydrates.
- Meat and eggs are good sources of protein.
- Calcium and phosphate are examples of minerals essential for body functions.
Digestive Processes and Organs
- Oils and fats are usually liquid at room temperature and classified as lipids.
- The process of grinding food into smaller pieces and mixing it with digestive juices is called mechanical digestion.
- In chemical digestion, proteins are broken down into amino acids.
- The pancreas is an accessory organ involved in digestion but is not part of the alimentary canal.
Digestive Functionality
- Peristalsis involves rhythmic contractions that move food through the digestive tract.
- The mixture of food, enzymes, and acids leaving the stomach for the small intestine is called chyme.
- Most water and mineral absorption occurs in the large intestine.
- The pancreas is responsible for producing most digestive enzymes and aids in breaking down food.
Digestion and Excretion
- The digestion process begins in the stomach, where chyme is produced.
- The mouth performs mechanical digestion for the first time by breaking food physically.
- The primary function of the excretory system is to remove waste products from the body.
- The gallbladder stores bile, which helps in the digestion of fats.
- The small intestine begins the chemical digestion of carbohydrates through enzymes.
Urinary System Components
- The ureter is the tube that leads from the kidney to the bladder.
- Chyme production is primarily the result of stomach digestion processes.
- In the urinary system, the initial event involves filtration of blood to form urine.
- Most digestive enzymes are produced in the pancreas, supporting various chemical reactions.
Kidney Functionality
- Nephrons are the structures in the kidney that filter wastes from the blood, leading to urine formation.
- Urine contains waste materials and substances removed from the blood.
- Proteins provide necessary amino acids for building body structures and regulating biochemical reactions.
Nutritional Elements and Their Functions
- The esophagus is the passageway for food into the stomach.
- Fiber, often found in fruits and vegetables, aids digestion and promotes gut health.
- The rectum eliminates undigested waste from the body.
- Fats are used to protect internal structures and store excess energy, acting as a reserve energy source.
- The small intestine absorbs the majority of nutrients from digested food.
