Step 1
The laryngopharynx is the part of the pharynx that is below the oropharynx and above the esophagus. The options are epiglottis, voice box, soft palate, and hard palate. The epiglottis is a flap of cartilage that covers the trachea during swallowing. The voice box Show more…

Why is the pancreas both an endocrine and an exocrine gland? It secretes bile through the pancreatic duct and insulin into the blood. It secretes insulin through the pancreatic duct and bile into the blood. It secretes secretin through the pancreatic duct and insulin into the blood. It secretes digestive enzymes through the pancreatic duct and insulin into the blood. It secretes insulin through the pancreatic duct and secretin into the blood. The portal system carries nutrient-rich blood from the digestive system to the __________, where toxins can be inactivated and vitamins removed and stored. heart small intestine. brain liver. esophagus. Why do we breathe oxygen? It provides energy directly to the body. Mitochondria need oxygen because it is the final acceptor of electrons in the electron transport chain. Oxygen allows us to release carbon dioxide waste. All human tissue can perform fermentation, so technically we don't need oxygen. Oxygen supports all life. What type of epithelium would you find forming the alveoli in the lungs simple squamous epithelium pseudostratified ciliated columnar epithelium simple columnar epithelium stratified cuboidal epithelium stratified squamous epithelium During respiration, which structure connects the larynx to the bronchiole tree? trachea glottis lungs alveoli esophagus What diffuses from the air through the lung and into the blood? oxygen carbon dioxide water nitrogen methane The lungs have contractile tissue and can breathe without the help of the skeletal muscles or ribs. True False The site of gas exchange in the respiratory system is the trachea bronchus oral epithelium alveolus bronchiole The vocal cords are connective tissue strands that vibrate to make sound and are found in the esophagus trachea pharynx larynx nasal cavity gastro, pulmonary and cardio refer respectively to heart, lung and stomach stomach, liver and lung liver, lung and heart stomach, heart and lung stomach, lung and heart What gas do we breathe out that result from the oxidation of our foodstuffs? carbon monoxide oxygen carbon dioxide water high energy electrons
