The Respiratory System Flashcards
It is the process wherein food is broken down in the cells with the help if oxygen to release energy.
Respiration
It can be simply defined as the physical process of inhalation and exhalation wherein oxygen is obtained and carbon dioxide is expelled, respectively.
Breathing
It is the gas exchange that occurs between the alveoli of the lungs and blood.
External Respiration
It is when the blood transports the oxygen from the alveoli to the cells, and carbon dioxide is transported from the cells to the alveoli.
Transport of respiratory gases
It is the gas exchange that occurs between the blood and cells.
Internal Respiration
What are the two human respiratory systems?
The upper respiratory tract and the lower respiratory tract
It is the holes in your nose and the first entry of the inhaled air.
Nostrils or nares
What are the three regions of the cavity?
Vestibule region, Respiratory region, and Olfactory region
It is lined with mucus that traps microorganisms and other debris in the inhaled air. It serves as the first line of defense against foreign invaders that may enter the body.
Vestibule Region
It warms the inhaled air so that its temperature comes close to the normal body temperature (37 degrees celsius).
Respiratory Region
It is composed of highly sensitive cells that send the stimulus (smell) to the brain and aid in determining the smell.
Olfactory Region
It is also known as the throat.
Pharynx
What are the three parts of the pharynx?
Nasopharynx, Oropharynx, and Laryngopharynx
It serves as a common chamber for the inhaled air and ingested food.
Pharynx
This makes sure that the bolus will go to the food pipe.
Epiglottis
It is also known as the voice box.
Larynx
It is open when a person is breathing to allow air to go into the lungs. And it is closed when speaking.
Larynx
It is also known as the windpipe.
Trachea
It is surrounded with hyaline cartilage that gives strength and flexibility to the tracheal muscles.
Trachea
It is the entry point of the air to the lungs.
Bronchi
It is the smaller branches of the bronchi.
Bronchioles
These are grape-like structures and the actual site of gas exchange.
Alveoli
It is a process wherein substances move from an area of high concentration to one of lower concentration.
Diffusion
It is when each individual exerts pressure.
Partial Pressure
It is the sum of all partial pressures.
Total Pressure
What is the complex structure called once the oxygen is bound to hemoglobin?
Oxyhemoglobin
What is the complex structure called once the carbon dioxide is bound to hemoglobin?
Carbaminohemoglobin
It is the case that protects the lungs.
Rib cage
It is the bone found on the chest at the center.
Sternum
It is the one surrounding the lungs.
Ribs
It is a bone found at the dorsal (back) side.
Vertebrae
These are located between the bones.
Intercostal Muscles
It moves down during inhalation to accommodate the inhaled air.
Diaphragm
It is a process wherein the diffusion of gases can occur across their skin surfaces.
Cutaneous Respiration
This is the reddish part of the fish.
Gills
It is the mechanism where the blood and water flow in the opposite direction.
Countercurrent exchange
It is the mechanism where the blood and water flow in the same direction.
Concurrent exchange
It is when the airways become narrow, and swelling is evident.
Asthma
The alveoli in one or both lungs are inflamed and filled with fluid or pus.
Pneumonia
It is when the airflow from the lungs is obstructed.
Chronic Obstructive Pulmonary Disease (COPD)
It is the abnormal growth of lung cells.
Lung cancer
