Human respiration/ Excretion Flashcards
Summarise the route of air through the reparatory system?
Nostrils, nasal cavity, pharynx, laryna, trachea, bronchi, bronchial tubes (bronchioles), Alveoli (air sacs)
What is the pharynx?
Te muscular type that is the gateway to the trachea and digestive tract; the throat.
what is the epiglottis?
Elasctic cartilage at e back of the throat; covers the owning to the respiratory tract dying swelling.
What is the larynx?

What is the trachea?
The trachea (windpipe) caries air btwen the larynx and the bronchi.
What is the Bronchi?
Bronchi are tubes that carry air from the trachea into the lungs.
What are the bronchial Tubes? (Bronchiole?)
The bronchi are divided into smaller tubes called bronchial tubes or bronchioles.
What are Alveolus?
One of the many air sacs located at the end of each bronchiole; gas exchange with the circulatory system takes place here.
What is the thorax?
The Thorax is the chest cavity: it contains the heart and lungs.
What is the diaphragm?
The Diaphragm is a sheet of muscle tissue that separate the thoracic and abdominal cavities; functions in breathing.
What is the pleural membrane?
A thin, smooth membrane that covers each lunch hand lines each half of he thoracic cavity.
What is the kidney?
An organ that filters blood to remove nitrogenous wastes; also regulates the water and solute balance in the blood. Urine passes from the kidney to the ureter.
What is the renal artery?
Blood vessel that carries nitrogenous waste-containing blood to the kidney.
What are the nephrons?
The Nephrons are the functional unit of the kidney; one of many tubules involved in filtration and selective reabsorption of blood.
What is the glomerulus?
In the kidney, a dense network of capillaries enclosed by a Bowman’s capsule.
