The Respiratory System Anatomy Questions! Quiz

When oxygen enters our cells, it undergoes a process called cellular respiration, where it is used to produce energy in the form of ATP. As a byproduct of this process, carbon dioxide is released. This carbon dioxide then diffuses out of the cells and into the bloodstream, where it is transported to the lungs and eventually exhaled out of the body. Therefore, the correct answer is carbon dioxide.

The respiratory system provides oxygen to the bloodstream. Oxygen is inhaled through the nose or mouth, passes through the trachea and bronchial tubes, and reaches the lungs. In the lungs, oxygen is exchanged for carbon dioxide through the process of respiration. Oxygen-rich blood is then transported to the rest of the body through the bloodstream, providing the necessary oxygen for cellular respiration and energy production.

The diaphragm's main function is to assist in the process of breathing. It contracts and relaxes to create changes in pressure within the chest cavity, which helps pump carbon dioxide out of the lungs during exhalation and pull oxygen into the lungs during inhalation. This ensures that the body receives an adequate supply of oxygen and removes waste carbon dioxide, supporting normal respiration and maintaining proper oxygenation of the blood.

Corinna is yelling at Matthew, which involves the production of sound through her vocal cords. The larynx, also known as the voice box, is responsible for producing sound by controlling the tension and vibration of the vocal cords. It acts as a passageway for air to flow in and out of the respiratory system, allowing Corinna to project her voice and yell at Matthew. The epiglottis is responsible for preventing food and liquid from entering the airway, cilia are tiny hair-like structures that help in moving mucus and foreign particles out of the respiratory tract, and the heart is not directly involved in the production of sound.

Smoking is a known risk factor for various diseases, including brain diseases, heart diseases, and jaw cancer. The toxic chemicals present in tobacco smoke can damage the blood vessels and increase the risk of stroke and other brain diseases. Smoking also increases the risk of heart diseases such as heart attack and coronary artery disease. Additionally, smoking is a major cause of oral cancer, including cancer of the jaw. Therefore, all of the given options are correct as smoking can cause all of these diseases.

When Ross hiccups, it is due to the spasm of the diaphragm. The diaphragm is a muscle that separates the chest cavity from the abdominal cavity and plays a crucial role in the process of breathing. Hiccups occur when the diaphragm contracts involuntarily, causing a sudden intake of breath that is then abruptly stopped by the closure of the vocal cords. This closure creates the characteristic "hic" sound.

Smoking can cause second hand smoke to people around you. Second hand smoke refers to the smoke that is exhaled by a smoker or comes from the burning end of a cigarette. It contains harmful chemicals and toxins that can be inhaled by others nearby. This can lead to various health issues such as respiratory problems, lung cancer, heart disease, and even premature death. Therefore, it is important to be considerate of others and avoid smoking in close proximity to non-smokers.

The pharynx is the correct answer because it is the passageway that connects the nose to the throat. When air enters the nose, it travels through the pharynx before reaching the trachea and eventually the lungs. The pharynx also plays a role in swallowing and speech production. The cilia are tiny hair-like structures in the respiratory tract that help to filter and move mucus and foreign particles out of the airways. The heart is not involved in the pathway of air entering the nose.

The correct answer is 600 million. Alveoli are tiny air sacs located in the lungs where the exchange of oxygen and carbon dioxide takes place. They play a crucial role in respiration. An adult typically has around 600 million alveoli, providing a large surface area for efficient gas exchange.
