Instituto Rafael Haller Biology 102 Respiration Lesson 1
| Vocabulary Word | Definition |
|---|---|
| Respiration | Entrance of oxygen to the body of a living being and the output of carbon dioxide |
| Gas exchange | Process by which oxygen enters the body, and CO2 exits the body. |
| Oxygen | helps in the extraction of nutrients |
| Extraction | Process to extract the energy contained in nutrients |
| Cellular respiration | the reactions and processes that take place in the cells of organisms to convert energy from nutrients into adenosine triphosphate (ATP) |
| Carbon Dioxide | waste from cellular respiration with Water Vapor |
| Water vapor | waste from cellular respiration with Carbon Dioxide |
| Nutrients | Thing that can provide energy |
| Respiratory system | System needed to provide oxygen to the different cells of a pluricellular body. |
| Oral Cavity | the back part of the mouth |
| Diaphragm | muscle that helps with respiration |
| Thoracic Box | Made by the ribs to protect the lungs and the heart |
| Inhalation | is the filling of the lungs with air |
| Nostrils | channels of the nose |
| Nasal cavity | large air filled space above and behind the nose in the middle of the face |
| Pharynx | part of the throat located behind the mouth |
| Trachea | tube that connects the larynx to the lungs |
| Larynx | place of the throat that houses the vocal cords |
| Bronchi | a passage of airway in the respiratory tract that conducts air into the lungs |
| Bronchiole | branches of bronchi that contains the alveoli |
| Vocal Cords | They vibrate, modulating the flow of air being expelled from the lungs, creating the voice |
| Epiglottis | a flap attached to the entrance of the larynx. |
| Lungs | the essential respiration organ in many air-breathing animals |
| Alveoli | an anatomical structure where the gas exchange takes place |
| Aerobic Respiration | requires oxygen in order to generate energy (38 ATP) |
| Anaerobic Respiration | doesn’t require oxygen in order to generate energy ( 2 ATP) |
