    Study Notes

    Digestive System and Respiratory System Overview

    • Small intestine facilitates the absorption of proteins, fatty acids, sugars, vitamins, and minerals into the bloodstream due to its large surface area
    • Majority of chemical digestion of proteins, fats, and carbohydrates occurs in the small intestine
    • Large intestine absorbs water, vitamins, minerals, and maintains health with the help of bacteria and mucus
    • Common health problems of the digestive system include gastro-oesophageal reflux, diverticulitis and diverticulosis, stomach ulcers, haemorrhoids, and constipation
    • Respiratory system includes the voice box, windpipe, nose, mouth, throat, and lungs
    • The mouth and nose act as entry points for air into the respiratory system and warm and humidify the air
    • The pharynx serves as a pathway for both air and food, and the epiglottis prevents food and liquid from entering the lungs
    • The larynx contains vocal cords that vibrate to produce sounds
    • The trachea, or windpipe, has cartilage rings and cilia to keep fluids and foreign objects out of the lungs
    • The bronchi branch off into smaller bronchi and bronchioles within the lungs, leading to alveoli where the exchange of carbon dioxide and oxygen occurs
    • The respiratory system allows the body to absorb oxygen and remove carbon dioxide, with the diaphragm and rib muscles facilitating inhalation and exhalation
    • Oxygen moves from the alveoli into the blood through capillaries, where it is absorbed by red blood cells' haemoglobin and transported to oxygen-hungry tissues via arteries; carbon dioxide produced by cells is released into the blood and carried back to the heart through veins
