Accessory Organs and Macronutrients Quiz

Study Notes

Accessory Organs

Liver: Produces bile, critical for fat digestion and absorption.
Liver: Processes nutrients from the small intestine and eliminates harmful substances.
Liver: Stores glycogen, vitamins, and minerals for maintaining bodily equilibrium.
Pancreas: Secretes digestive enzymes (lipase, proteases, amylase) into the small intestine for breakdown of food.
Pancreas: Regulates blood sugar with insulin and glucagon, essential hormones for energy balance.
Gallbladder: Stores and concentrates bile until needed in the small intestine.
Gallbladder: Bile assists in fat breakdown (emulsification) enhancing digestion.

Macronutrients

Carbohydrates: Provide energy, composed of sugar molecules.
- Simple Carbohydrates: Found in fruits, dairy, and table sugar, provide quick energy but should be consumed in moderation due to potential blood sugar spikes.
- Complex Carbohydrates: Found in whole grains, legumes, and vegetables, offer sustained energy and dietary fiber, promoting digestive health.
Proteins: Essential for various bodily functions, composed of amino acids.
- Nine Essential Amino Acids: Must be obtained through diet, not produced by the body.
- Protein Sources: Meat, fish, eggs, dairy, legumes, and nuts.
- Protein Functions: Tissue building and repair, enzyme and hormone production, immune system support.
Fats: Provide energy and support cell structure.
- Saturated Fats: Usually solid at room temperature, found in animal products and some plant oils. Excessive intake can raise cholesterol levels and increase heart disease risk.
- Unsaturated Fats: Generally liquid at room temperature, found in plant oils, avocados, nuts, and fish. Beneficial for heart health and should be included in a balanced diet.
- Trans Fats: Artificially produced through hydrogenation, found in processed foods. Harmful and should be avoided.

Micronutrients

Vitamins: Essential for various bodily functions.
- Water-Soluble Vitamins: Include vitamin C and B vitamins. Important for energy metabolism, red blood cell production, and immune function. Must be consumed regularly as they aren't stored in the body.
- Fat-Soluble Vitamins: Include vitamins A, D, E, and K. Stored in the liver and fatty tissues. Essential for vision, bone health, antioxidant function, and blood clotting.
Minerals: Important for various bodily functions.
- Calcium: Essential for strong bones and teeth, muscle function, and nerve transmission. Found in dairy products, leafy greens, and fortified foods.
- Iron: Important for hemoglobin production and oxygen transport in the blood. Found in red meat, poultry, fish, beans, and fortified cereals.
- Potassium: Vital for heart health and muscle function. Found in bananas, oranges, and potatoes.
Water: Constitutes about 60% of the human body. Critical for:
- Hydration
- Nutrient transport
- Temperature regulation
- Waste removal
