Respiratory system Flashcards
What system is a set of organs that allows an organism to exchange gases throughout the body.
Respiratory system
- Nose
- Nasal Cavity
- Pharynx
- Larynx
Upper Respiratory tract
- Trachea
- Bronchi
- Bronchioles
- Alveoli
- Lungs
Lower Respiratory tract
The ___ Filters air using hair like ___
- Nose and Nasal cavity
- Cilia
The ___ moistens the air in the
chambers called ___
- Nose and Nasal cavity
- Sinuses
Known as throat
Pharynx
Closes airway when swallowing food
Epiglottis
Known as voice box and produces sound
Larynx
What part is the passageway of air to the lower Respiratory tract
Larynx
Known as windpipe and is made of flexible cartilage (soft bone tissue) to make it open and rigid
Trachea
Extension of trachea that divides leads to lungs
Bronchi
Each bronchus will branch out to more ____ then ending as air sacs
Bronchioles
Known as the air sacs
Alveoli
Site of Respiration and gas exchange via diffusion
Alveoli
Pair of organs that contain bronchi, bronchioles and alveoli
Lungs
Dome like muscle that enables body to inhale and exhale
Diaphragm
Mechanical movement of air towards lungs
breathing
Diaphragm contracts and rib cage expands
inhalation
Diaphragm relaxes and rib cage lowers down
exhalation
Respiration is classified into __
2
type of respiration
Gas exchange between atmosphere and blood
External
type of respiration
Gas exchange between blood and body cells
Internal
pathway of oxygen to the lungs
nose-pharynx-larynx-trachea-bronchus-bronchiole-alveolus
pathway of oxygen from the lungs to body tissues
alveoli-RBC-bloodstream-tissues
movement of both oxygen and carbon dioxide in the body is accomplished by ____
diffusion
Involves Diaphragm and Nose
breathing
type of respiration
Involves Alveoli
External Respiration
type of respiration
when the cells themselves are using the oxygen to break down their food nutrient and produce energy.
Cellular Respiration
disease
a disease caused by pathogens such as viruses (adenovirus, rhinovirus, influenza) these viruses enter mucous membranes (eyes, mouth, nose) and spread through respiratory sections
common cold (sneezing, runny nose, cough, nasal congestion)
disease
virus that can cause inflammation of lungs and damage of respiratory cells, can also lead to other infections because respiratory system is weakened by virus
Influenza/flu
disease
Chronic lung disease that disrupts airflow causing difficulty breathing, caused by: inflammation, too much mucus in airways, tightening of muscles in airways, cannot be cured but can be MANAGED
Asthma
disease
deadly infectious disease caused by bacteria, viruses, and chemical irritants entering lungs, and filling alveoli with pus. Patients have difficulty breathing. Is usually treated with antibiotics and can be resolved by body naturally
Pneumonia
disease
Caused by Mycobacterium ___, which usually targets lungs and is transmitted through air
Tuberculosis
disease
Growth of abnormally mutated cells that have been out of control. Deadliest kind of cancer, caused by smoking, secondhand smoke, and exposure to toxic gas.
Lung cancer
