The Respiratory System Pt. 1

Question 1

Respiratory System Includes?

Answer 1

the nose, pharynx (throat), larynx (voice box), trachea (windpipe), bronchi, and lungs, provides for gas exchange, the intake of 02, and the removal of C02

Question 2

Respiratory Function?

Answer 2

regulate blood pH; contains receptors for the sense of smell; filters, warms, and moistens inspired air; produces sounds; and rids the body of some water and heat in exhaled air.

Question 3

The entire process of gas exchange in the body, called respiration, occurs in three basic steps:

Answer 3

Pulmonary ventilation
External respiration
Internal respiration

Question 4

The respiratory system can also be divided into 2 parts or zones:

Answer 4

The Conducting zone consists of a series of interconnecting cavities and tubes both outside and within the lungs.

The Respiratory zone consists of tissues within the lungs where gas exchange occurs between air and blood.

Question 5

Organs of the Respiratory System

Answer 5

Diagram - Slide 8/9

Question 6

Specialized organ at the entrance to the respiratory system.

Answer 6

Nose

Question 7

Openings to the exterior are the:

Answer 7

or nostrils; exterior nares) allow air to enter the nose and pass into the nasal cavity. Individually, each opening is referred to as an anterior naris.

Question 8

Nose Function?

Answer 8

The nose is adapted for warming, moistening, and filtering air; olfaction; and serving as a resonating chamber.

Question 9

Funnel-shaped tube that starts at the internal nares and extends partway down the neck.

Answer 9

The PHARNYX (throat)

Question 10

Pharynx function?

Answer 10

Passageway for air and FOOD is a resonating chamber for speech sounds and houses the tonsils.

Question 11

Pharynx 3 regions/ Functions?

Answer 11

The nasopharynx, oropharynx, and laryngopharynx.

The nasopharynx functions in respiration.
The oropharynx and laryngopharynx function both in digestion and in respiration.

Question 12

Larynx (VOICE BOX) ?

Answer 12

Connects the pharynx and the trachea. It contains the thyroid cartilage (Adam’s apple), the epiglottis, the cricoid cartilage, arytenoid cartilages, false vocal cords, and true vocal cords.

Question 13

Is controlled by the TENSION of the vocal folds.

Answer 13

Pitch

Question 14

Extends from the larynx to the primary bronchi. It is composed of smooth muscle and C-shaped rings of cartilage

Answer 14

The trachea (WIND PIPE)

Question 15

Question 16

Trachea divides into?

Answer 16

a right main (Primary) bronchus, which goes to the right lung, and a left main (primary) bronchus, which goes to the left lung.

Question 17

The main bronchi divide to form?

Answer 17

the lobar (Secondary) bronchi, one for each lobe of the lung.
(The right lung has three lobes; the left lung has two.)

Question 18

The lobar bronchi continue to branch, forming still smaller bronchi, called?

Answer 18

Segmental (Tertiary) bronchi, that divide several times giving rise to smaller bronchioles

Question 19

Bronchioles, in turn, branch into even smaller tubes called?

Answer 19

Terminal bronchioles

Question 20

Airways resemble an upside-down tree with many branches, their arrangement known as?

Answer 20

The Bronchial Tree

Question 21

Are paired organs in the thoracic cavity enclosed by a 2 layers known as what layer?

Answer 21

Lungs- The parietal pleura is the outer layer.

Question 22

Known as the inner layer

Answer 22

Visceral pleura

Question 23

How many lobes does the right lung have? Separated by how many fissures?

Answer 23

3 lobes ; separated by 2 fissures

Question 24

How many lobes does the left lung have?
Separated by how many fissures?

Answer 24

2 lobes; separated by one fissure plus a depression, the cardiac notch.

Question 25

Each lobe consists of? Which contain?

Answer 25

lobules, which contain lymphatic vessels, arterioles, venules, terminal bronchioles, respiratory bronchioles, alveolar ducts, alveolar sacs, an alveoli.

Question 26

Exchange of gases (O2, and CO2) in the lungs happen in?

Answer 26

the respiratory membrane.
