Study Notes
Nutrition and Energy
- Heterotrophs, like humans, must obtain food in the form of complex molecules from other creatures
- Food consists mainly of water, with the remaining components being proteins, carbohydrates, and fats
- Vitamins and minerals are also essential for the proper functioning of the body, and their deficiency can lead to diseases
Macronutrients
- The three macronutrients are:
- Proteins: broken down into polypeptide chains and amino acids
- Carbohydrates: broken down into sugars (e.g., glucose, fructose, galactose)
- Fats: broken down into fatty acids and glycerol
Vitamins and Minerals
- Vitamins and minerals are essential for the proper functioning of the body
- Deficiencies in vitamins and minerals can lead to diseases
- Examples of vitamins and minerals include:
- Vitamins: A, C, D, E, K, and B complex
- Minerals: calcium, iron, zinc, and potassium
Digestive System
- The digestive system is a complex process that involves the breakdown of nutrients into smaller molecules that can be absorbed and utilized by the body
- The large intestine (colon) is responsible for:
- Absorbing water and electrolytes
- Producing and absorbing vitamins
- Forming and propelling feces towards the rectum for elimination
- The parts of the large intestine include:
- Cecum: receives processed material from the small intestine
- Colon: the longest part of the large intestine, divided into ascending, transverse, descending, and sigmoid colon
- Rectum: the last 20 cm of the large intestine, responsible for holding waste products until elimination
- The appendix is a small projection at the junction of the small and large intestines, which does not serve a digestive function in humans but helps digest cellulose in some plant-eating animals
Digestive System Disorders
- Constipation: infrequent or hard-to-pass bowel movements, often due to low fiber or water intake, and can be treated with laxatives, fiber-rich foods, and increased water intake
- Stomach ulcers (H. pylori): bacteria that prevent mucus-producing cells from functioning properly, causing burning sensations or pain in the middle of the abdomen, and can be treated with antibiotics and medication
- Diarrhea: loose, watery stools and frequent bowel movements, often caused by bacterial or viral infections, and can be treated with the BRAT diet, drinking water, and staying hydrated
