|
Due to what structural changes does the respiratory system become less efficient with age?
|
due to decrease in elastic connective tissue, which reduces the amount of gas that can be exchanged in decrease in the ventilation rate,
Carbon, dust, and pollution material gradually accumulate in our lymph nodes and lungs, |
|
|
What 2 diseases together encompass chronic obstructive pulmonary disease (COPD), and what is it often related to?
|
emphysema and chronic bronchitis, often related to tobacco use
|
|
|
What is COPD?
|
chronic obstructive pulmonary disease, characterized by lung structural abnormalities resulting from inflammation, makes it hard for the patient to EXHALE!!!
|
|
|
how does emphysema lead to a loss of gas exchange within in the lungs?
|
due to inflammation of the terminal bronchioles and alveoli, in conjunction with teh widespread destruction of pulmonary elastic connective tissue. These combined events lead to an increase in teh diameter or dilation of individual alveoli, resulting in a decrease in the total number of alveoli.
|
|
|
What are a person's symptoms with advanced emphysema?
|
Larger than normal chest circumference because air is trapped within the abnormally expanded and nonfunctional alveoli. inability to exhale.
|
|
|
What disease is associated with a wider chest circumference?
|
emphysema
|
|
|
What is a highly aggressive and frequently fatal malignancy that originates in the epithelium of the respiratory system?
|
Lung cancer
|
|
|
What percentage does smoking cause in all lung cancers?
|
85%
|
|
|
what 3 basic patterns are lung cancers classified into?
|
1. Squamous cell carcinoma (most common)
2.Adenocarcinoma 3.small cell carcinoma |
|
|
which type of lung cancer is associated with a strudier stratified squamous epithelium in order to withstand the chronic inflammation and injury caused by tobacco smoke?
|
squamous cell carcinoma.
|
|
|
which type of lung cancer arises from the mucin-producing glands in teh resp epithelium, begins when DNA injury causes one of these cells to become malignant and begin to divide uncontrollably?
|
adenocarcinoma
|
|
|
Which type of lung cancer originates in the primary bronchi and eventually invades the mediastinum? Is especially known for its early metastasis to other organs
|
Small-cell carcinoma
|
|
|
What effects does emphysema have on the body?
|
causes dilation of the alveoli and loss of elastic tissue, resulting in poorly functioning alveoli, making it difficult for a patient to EXHALE
|
|
|
What is another name for SIDS? which way should you lay your baby in the crib to avoid SIDS and is it more common in males or females?
|
Crib death, on back, 60% of males
|
|
|
What could also happen if you were mindful of laying an infant on their back to avoid SIDS?
|
plagiocephaly
