2. bronch/o, bronchi/o, b. passageway for air to the bronchi from the larynx
3. pulmon/o, c. spongelike organs located in the thoracic cavity
4. laryng/o, d. membrane covering the lung
5. pleur/o, e. lymphoid tissue located on the lateral wall at the junction of the oral cavity and oropharynx
6. thorac/o, f. air cavities within the cranial bones that open into the nasal cavities
7. trache/o, g. location of the vocal cords
8. tonsill/o, h. air sacs at the end of the bronchioles
9. sinus/o, i. the part of the body between the neck and diaphragm
10. mediastin/o, j. tube carrying air between the trachea and lungs

step 1: write the definitions after the following combining forms.
step 2: match the descriptions on the right with the combining forms and definitions.

Explanation:

1. Alveol/o: Alveoli are small air - filled sacs at the end of bronchioles, which match with "h. air sacs at the end of the bronchioles".
2. Bronch/o, bronchi/o: The bronchi are passageways for air to the bronchi from the larynx, so it matches with "b. passageway for air to the bronchi from the larynx".
3. Pulmon/o: This combining form is related to the lungs. The description "c. spongelike organs located in the thoracic cavity" fits as the lungs (pulmonary organs) are in the thoracic cavity and have a spongy texture due to the alveoli.
4. Laryng/o: The larynx is the location of the vocal cords, so it matches with "g. location of the vocal cords".
5. Pleur/o: The pleura is a membrane covering the lung, so it matches with "d. membrane covering the lung".
6. Thorac/o: The thoracic cavity is the space where the lungs (pulmonary organs) are located. The description "b. passageway for air to the bronchi from the larynx" is incorrect for this. The correct match is that the thoracic cavity is the cavity where the lungs (pulmonary - pulmon/o related) are. But among the given options, "b. passageway for air to the bronchi from the larynx" is wrong. Actually, thorac/o is related to the chest (thoracic) region. If we assume the intended match, maybe there was a mis - label. But based on the given options, if we consider the thoracic cavity as the cavity where the lungs (pulmon/o - related organs) are, and the only option related to cavity is "b. passageway for air..." which is wrong. But if we go by the combining form meaning, thorac/o means chest. However, among the given options, if we assume it's a mis - print and the intended match is with the thoracic cavity (where the lungs (pulmon/o) are located), but since the options are as given:
7. Trache/o: The trachea is the tube carrying air between the trachea (itself, which is a wrong description in the options. But if we consider the trachea as the windpipe that connects to the bronchi. The correct match is "j. tube carrying air between the trachea and lungs" is wrong. The trachea (windpipe) is a single tube. But if we assume it's a mis - print and it should be "tube carrying air to the bronchi", but among the options, the best fit is "j. tube carrying air between the trachea and lungs" (though anatomically not precise, but based on the given options).
8. Tonsill/o: Tonsils are lymphoid tissue. The description "e. lymphoid tissue located on the lateral wall at the junction of the oral cavity and oropharynx" matches as tonsils (palatine tonsils) are located in that area.
9. Sinus/o: Sinuses are air cavities within the cranial bones. So it matches with "f. air cavities within the cranial bones that open into the nasal cavities".
10. Mediastin/o: The mediastinum is the part of the body between the lungs containing heart, esophagus, etc. So it matches with "a. space between the lungs containing heart, esophagus, trachea, and other structures".

Answer:

1. h. air sacs at the end of the bronchioles
2. b. passageway for air to the bronchi from the larynx
3. c. spongelike organs located in the thoracic cavity
4. g. location of the vocal cords
5. d. membrane covering the lung
6. (Assuming a mis - print, but if we have to choose from given options, there is an error. But if we consider the thoracic cavity as the place for lungs (pulmon/o - related) and the only cavity - related option is wrong. But if we go by the combining form meaning (chest), but no correct option. If forced to choose from given, maybe no perfect match, but if we assume it's a mis - print and related to the cavity where lungs (pulmon/o) are, but no. However, if we skip the error in options and go by the intended learning (matching combining forms to basic definitions as per a textbook exercise, maybe the answer is based on the following incorrect but forced match: assume thorac/o is related to the cavity (though the option description is wrong for bronchi passage, but if we ignore that and match the combining form to the only cavity - related option (even if description is wrong for the combining form), but this is a stretch. But for the sake of answering as per the exercise's likely intention (despite option errors): b. passageway for air to the bronchi from the larynx (wrong, but if we consider it's a mis - labeled option for thorac/o (cavity) but no. Another approach: maybe the student is to match the combining form to the root word's basic meaning. Thorac/o - chest (no option). But if we assume it's a typo and the option for trache/o is wrong. But this is getting too convoluted. Alternatively, if we consider that in some basic medical terminology exercises, sometimes the matches are not perfect anatomically but by the combining form's basic word. For example:
7. j. tube carrying air between the trachea and lungs (anatomically, trachea divides into bronchi, but if we assume the exercise's simple match)
8. e. lymphoid tissue located on the lateral wall at the junction of the oral cavity and oropharynx
9. f. air cavities within the cranial bones that open into the nasal cavities
10. a. space between the lungs containing heart, esophagus, trachea, and other structures
