Q

The main vein carrying deoxygenated blood back to the heart

A

Vena Cava

23
Q

The main function of your respiratory system?

A

Warms and adds moisture to the air you breathe in, Protects your body from particles you breathe in, Allows you to talk, Helps you smell, Balances level of acidity in your body

24
Q

Caterpillars take in air by means of? (tiny holes along the sides of their bodies)

A

Spiracles

25
Q

Process by which organisms that live in water obtain oxygen from their surroundings and expel carbon dioxide

A

Aquatic Respiration

26
Q

are thin, highly vascularized structures that extract dissolved oxygen from water as it flows over them. Oxygen diffuses into the blood, and carbon dioxide diffuses out

A

Gills

27
Q

form of respiration where gas exchange occurs directly through the skin. Oxygen diffuses into the body, and carbon dioxide diffuses out, using the skin as the respiratory surface

A

Cutaneous Respiration

28
Q

a type of respiration where gas exchange occurs through the moist lining of the mouth and pharynx

A

Buccopharyngeal Respiration

29
Q

the process of gas exchange that occurs in the lungs of organisms. Oxygen is inhaled into the lungs, diffused into the bloodstream, and carbon dioxide is exhaled

A

Pulmonary Respiration

30
Q

structures from the nose to the larynx

A

Upper Respiratory Tract

31
Q

structures from the trachea through the alveoli in the lungs

A

Lower Respiratory Tract

32
Q

encompasses the structures from the nose to the smallest air tubes within the lungs and is strictly for ventilation

A

Conducting Zone

33
Q

solely within the lungs and includes some specialized small air tubes and the alveoli. Gas exchange occurs within the ____

A

Respiratory Zone

34
Q

Mainly composed of the hyaline cartilage

A

Nasal External Nose

35
Q

The open chamber inside the nose where air first enters the respiratory system

A

Nasal Cavity

36
Q

The floor of the nasal cavity, which separates it from the oral cavity in the mouth, is called the ?

A

Hard Palate

37
Q

The two halves of the nasal cavity are separated by a wall of tissue called the?

A

nasal septum

38
Q

three lateral bony ridges on each side of nasal cavity. It increase the surface area of the nasal cavity and helps in cleaning, humidifying, and warming of air

A

Conchae

39
Q

air filled spaces within bone. It opens into nasal cavity and is lined with mucus

A

Paranasal Sinuses

40
Q

a common passageway for the respiratory and digestive systems

A

Pharynx

41
Q

Adam’s apple

A

Thyroid Cartilage

42
Q

flap that prevents swallowed materials from entering the larynx

A

Epiglottis

43
Q

false vocal cords

A

Vestibular Folds

44
Q

are the primary source of sound production. Air moving past the ____ causes them to vibrate and produce sound.

A

Vocal Folds

45
Q

allows air to flow into the lungs. Consists of 16 to 20 C-shaped pieces of cartilage called tracheal ring

A

Trachea (Wind Pipe)

46
Q

16 to 20 C-shaped pieces of cartilage

A

Tracheal ring

47
Q

divides to form two smaller tubes called main bronchi, or primary bronchi, each of which extends to a lung

A

Bronchi

48
Q

site of gas exchange. _____ are small, air-filled chambers where the air and the blood come into close contact with each other

A

Alveoli

49
Q

The diaphragm contracts and moves downward, expanding the chest cavity.
This allows air to enter the lungs

A

Inhalation

50
Q

The diaphragm relaxes and moves upward, reducing the chest cavity size. This forces air out of the lungs

A

Exhalation

51
Q

Gas exchange in the lungs occur in the ____, tiny air sacs in the lungs

A

Alveoli

52
Q

A condition where airways become inflamed and narrow, making it hard to breathe

A

Asthma

53
Q

Includes chronic bronchitis and emphysema, causing airflow blockage

A

Chronic Obstructive Pulmonary Disease (COPD)

54
Q

An infection that inflames air sacs in the lungs, which may fill with fluid

A

Pneumonia

55
Q

A bacterial infection primarily affecting the lungs

A

Tubercolosis

56
Q

Uncontrolled growth of abnormal cells in the lungs

A

Lung Cancer
