Respitory System Flashcards
Coryza
The common head cold characterized by acute inflammation of the nasal mucosa
Anterior Nares
Exterior nostrils
Exudate
Accumulation of a fluid in a cavity or matter that penetrates through vessel walls into adjoining tissue
Hemothorax
Bloody fluid in the pleural cavity
Hilum
Depression where ducts, nerves, or vessels enter or exit an organ
Pneumothorax
A collection of air or gas in the pleural cavity characterized by pain in side and painful breathing; can lead to the collapse of the lung
Posterior nares
Opening between the nasal cavity and the nasopharynx
Purpose of the respiratory system
To bring air and blood into intimate contact so that oxygen can be added to the blood and CO2 can be removed
Characteristics of respiratory and breathing
- Respiratory is defined as the taking in of oxygen, it’s use in the tissue, and the giving off of carbon dioxide
- 2 types of respiration
A. External respiration
(1) process of taking air into the lungs and passing oxygen from the alveoli into the blood
(2) also called pulmonary respiration
B. Internal Respiration
(1) process of passing oxygen from the blood into the cells, it’s utilized by the cells, and passing CO2 from cells into blood
(2) AKA Cellular Respiration
Normal respirators per minute?
14-20
The ________ is subdivided into smaller and smaller _____ , eventually ending in microscopic branches which divided into _______ ducts, which end in several alveolar sacks consisting of numerous alveoli (___ cells)
Bronchioles
Tubes
Alveolar
Air
The _____ the two primary bronchi, and their many branches resemble an _____ tree, and are spoken of as the ________ tree.
Trachea
Inverted
Bronchial
By the time the branches of the bronchial tree have ________ to form _______, only the internal surface layer of cells remain
dwindled
Alveoli
_______ ducts and sacs look like a _______ of grapes, with the stem as the alveolar duct, each cluster as an ______ sac, and each grape as an alveoli
Alveolar
Cluster
Alveolar
Bronchi provides a _________by which air can reach the alveoli of the _____
Passageway
Lungs
The alveoli provides spaces where _____ exchange between the ____ and the blood can occur
Gaseous
Air
Characteristics of the lungs
- Are the essential organs of respirations
- cone-shaped and large enough to fill a plural portion of the thoracic cavity
- spongy, elastic, and float in water
- The two long sit side-by-side and extend from the diaphragm to appoint slightly above the clavicles, and lie against the ribs anteriorly and posteriorly
- The medial surface of each lung is concaved to allow room for the mediastinal structure of the heart
- The long room is composed of our structures entering and leaving along which includes
(1) primary bronchi
(2) pulmonary arteries and veins
(3) bronchial arteries and veins
(4) lymph vessels and nodes
(5) nerves - Apex of the lung is the point of upper margin which extends slightly above the clavicle
- base of the Lung is broad inferior surface which lies on the diaphragm.
- the left lung has an indentation for the heart called the cardiac notch or depression
Right lung is slightly ______, ______, and ______ by about one inch of the other side
Larger
Heavier
Shorter
Blood supply to the ____ _____is the bronchial arteries which are branches from the ________ aorta
Lung tissue
Thoracic
At birth the lungs are ____, but with increased age they become ______, gray color due to inhalation of _____,____,______
Pink
moltted
Dust, pollution, smoke
