How many different types of tissues are there in the human body? a. 4 b. 6 c. 8 d. 10 4 what is the name of the outermost layer of the skin? a. dermis b. epidermis c. subcutaneous tissue d. hypodermis epidermis The respiratory system can be divided into? upper and lower respiratory system what does the upper respiratory includes? nose, nasal cavity, mouth, pharynx, and larynx. what does the lower respiratory includes? trachea, lungs, and bronchial tree The airway of the respiratory system includes? nose, nasal cavity, mouth, pharynx, larynx trachea, bronchi, and bronchial network. what is the airway lined with? cilia that reap microbes and debris and sweep them back toward the mouth. The lungs are structures that? house the bronchi and bronchial network, which extend into the lungs and terminate in millions of alveoli. the walls of the alveoli are? one cell thick, allowing for the exchange of gases with the blood capillaries that surround them. the right lung has how lobes? 3 how lobes does the left lung have? 2, leaving room for heart on the left side of the body. what are the lungs surrounded by? pleural membrane which reduces friction between surfaces when breathing. what does the respiratory muscles include? diaphragm, and the intercostal muscles. what is the diaphragm? dome-shaped muscle that separates the thoracic and abdominal cavities. where are the intercostal muscles located? between the ribs what is the main function of the respiratory system? supply the body with oxygen and rid the body of carbon dioxide. where does exchange of gases occurs? in millions of tiny alveoli, which are surrounded by blood capillaries. as air passes through the throat, it moves through the? larynx which vibrates and produces sound, before it enters the trachea. the larynx is also known as? voice box the trachea is also known as? windpipe The respiratory system function in the sense of? smell The chemoreceptors that are located in the nasal cavity respond to? airborne chemical The respiratory system also helps the body maintain? acid-base homeostasis Hyperventilation can increase? blood pH during acidosis (low pH) slowing breathing during alkalosis helps lower? blood pH During the breathing process, the diaphragm and the intercostal muscles? contract to expand the lungs. during inspiration or inhalation, the diaphragm? contracts and moves down, increasing the size of the chest cavity. during expiration or exhalation, the intercostal muscles? contract and the ribs expand, increasing the size of the chest cavity. As the volume of the chest cavity increases, the pressure inside the chest? cavity decreases. because the outside air is under a greater amount of pressure than the air inside the lungs, air rushes into the lungs. when the diaphragm and intercostal muscles relax, the size of the chest cavity? decreases, forcing air out of the lungs. a defect in which parts of the bone would be most likely to result in stunted growth? epiphyseal plate the breathing process is controlled by? the portion of the brain stem called the medulla oblongata what are the 2 types of measurement important in science? quantitative and qualitative The medulla oblongata monitors the level of? carbon dioxide in the blood and signals the breathing rate to increase when these levels are too high. what is renal fascia? anchoring outer layer of dense fibrous connective tissue. what is bone? hard, calcified material that makes up the skeleton. what is brittle bone disease? a group of diseases that affect collagen and result in fragile bones.
