1
New cards

Lobes

Distinct sections or divisions of an organ, particularly used in reference to the lungs or brain.

2
New cards

Asymmetrical

Lack of symmetry or balance between two sides.

3
New cards

Alveoli

Tiny air sacs in the lungs where gas exchange (oxygen and carbon dioxide) takes place.

4
New cards

Capillaries

Tiny blood vessels that connect arteries and veins, facilitating the exchange of nutrients, oxygen, and waste products with tissues.

5
New cards

Diffusion

The movement of molecules from an area of higher concentration to an area of lower concentration, leading to equal distribution.

6
New cards

Trachea

The windpipe, a tube connecting the larynx (voice box) to the bronchi, allowing the passage of air to and from the lungs.

7
New cards

Rings of Cartilage

Circular structures made of cartilage that provide support and prevent the collapse of tubular organs, such as the trachea.

8
New cards

Asphyxiation

The condition of being deprived of oxygen, leading to unconsciousness or death.

9
New cards

Choking

A blockage of the airway that prevents normal breathing, often caused by a foreign object.

10
New cards

Pharynx

The throat, a muscular tube that connects the nasal and oral cavities to the larynx.

11
New cards

Larynx

The voice box, located in the neck, containing the vocal cords.

12
New cards

Bronchi

The large air passages that branch off from the trachea, leading to the lungs.

13
New cards

Bronchioles

Small, branching tubes within the lungs that connect the bronchi to the alveoli.

14
New cards

Diaphragm

A muscular sheet separating the chest cavity from the abdominal cavity, essential for breathing.

15
New cards

Boyle’s Law (P1V1 = P2V2)

A gas law stating that, at a constant temperature, the pressure and volume of a gas are inversely proportional.

16
New cards

Pleural Membrane

A double-layered membrane surrounding the lungs, creating a pleural cavity filled with pleural fluid that reduces friction during breathing.

17
New cards

Pleurisy

Inflammation of the pleura (lining around the lungs), causing pain during breathing.

18
New cards

Bronchitis

Inflammation of the bronchial tubes, often causing coughing and difficulty breathing.

19
New cards

Asthma

A chronic respiratory condition characterized by inflammation and narrowing of the airways, leading to difficulty breathing.

20
New cards

Bronchodilator

Medication that dilates and relaxes the bronchial tubes, easing airflow and alleviating symptoms of conditions like asthma or chronic obstructive pulmonary disease (COPD).

21
New cards

Corticosteroids

Synthetic drugs that mimic the effects of hormones produced by the adrenal glands, often used to reduce inflammation in conditions such as asthma or autoimmune diseases.

22
New cards

Pneumonia

An inflammatory condition of the lungs affecting the air sacs, leading to symptoms such as cough, fever, and difficulty breathing.

23
New cards

Protection

Measures taken to prevent harm, damage, or illness; safeguarding against potential threats.

24
New cards

Snot

Informal term for nasal mucus, a secretion produced by the nasal mucosa.

25
New cards

Nose Hair

Fine hairs inside the nostrils that help filter and trap particles from the air, preventing them from entering the respiratory system.

26
New cards

Nares

The nostrils, the openings through which air enters the nasal cavity.

27
New cards

Cilia

Tiny hair-like structures on the surface of cells, often found in the respiratory tract, that move in coordinated waves to help move mucus and trapped particles out of the airways.

28
New cards

Smoking

Inhaling and exhaling the smoke produced by burning tobacco or other substances.

29
New cards

1st Hand Smoke

Inhaled directly by the smoker.

30
New cards

2nd Hand Smoke

Inhaled by non-smokers exposed to the smoke.

31
New cards

3rd Hand Smoke

Residual chemicals left on surfaces after smoking.

32
New cards

E-cigarettes

Electronic devices that simulate smoking by producing an aerosol, often containing nicotine.

33
New cards

Popcorn Lung (Bronchiolitis Obliterans)

A condition linked to inhaling certain chemicals, often associated with microwave popcorn production but also linked to some e-cigarette liquids.

34
New cards

Addiction - Nicotine

A complex condition characterized by compulsive drug-seeking, use, and dependence. In the context of smoking, nicotine is the addictive substance found in tobacco.
