A & P - Resp System

A & P - Respiratory System

The lungs are found resting above this muscle that contracts causing air to enter the lungs during inhalation diaphragm
The top of the lungs is called this apex
These membranes are found covering the lungs and covering the inside of the thoracic cavity pleura
This is the portion of the respiratory track that is also a passage for food, it connects the mouth & nose pharynx
How many lobes are on the right side of the lungs? three
The respiratory center that ultimately controls breathing is found in this section of the brain medulla oblongata
The concentration of this substance in the blood is the primary chemical stimulus for breathing carbon dioxide
During exhalation the diaphragm and rib muscles do this relax
The normal breathing rate for a healthy adult is 12-20 breaths per what? minute
This structure in the respiratory tract, along with mucus and cilia, prevents pathogens from entering the body tonsils
This substance found in the lungs prevents them from collapsing surfactant
This is the process by which gas exchange in the lungs occurs diffusion
This term describes the volume of air in a normal breath tidal
This tube that directs air to the brochiole is found in the lower respiratory tract trachea
This cavity is responsible for filtering, warming, and moistening air entering the lungs nasal
If this structure fails to cover the entrance to the trachea, food may enter the windpipe and cause the person to cough or choke epiglottis
This structure is the voicebox; ot contains vocal cords to produce sound larynx
The actual exchange of gases occurs here alveoli
These are branches in the bronchi of the lungs bronchioles
These are branches of the windpipe that lead to the lungs bronchi
In this respiratory disorder the alveoli walls burst or fuse, reducing the surface area for gas exchange emphysema
This is the leading cause of emphysema, chronic bronchitis, and lung cancer. smoking
This disease causes the bronchi and bronchioles to spasm because of irritants such as dust and pet dander, causing narrowed, sometimes mucous filled airways and wheezing asthma
During inhalation the diaphragm _________ and flattens contracts
This diseases causes tumors to grow in the lungs that can eventually spread to other body parts during its later stages lung cancer
This respiratory disorder is characterized by inflammation and narrowing of the airways by increased mucus production because of contact with pollutants or smoking chronic bronchitis
Lung cancer can be treated by removing a lung or lobe of the lungs, with chemotherapy, or with _______. radiation
What is the sequence when tracing the path of air in the respiratory tract? pharynx, larynx, trachea, bronchi, bronchioles
