Q

The longer the vocal cords the lower the sound. As we grow older, vocal cords lengthen and our voice gets lower. Testosterone also lengthens your vocal cords.

Q

It is anterior to the epiglottis and at the base of the tongue. It serves as a spit trap and temporarily holds saliva to reduce the risk of coughing before it is swallowed.

Q

Tracheal Cartilages

A

The anterior walls of the trachea are supported by 15-20 C-shaped tracheal cartilages. They are completed by the trachealis muscle. These cartilages rings reinforce and provide some rigidity to the tracheal wall to make sure it stays open.

Q

It is the right and left branches of the trachea. The right branch leaves at a more acute angle and so the right side is more prone to have objects and vomit go down it.

Q

It is where the trachea splits into the the primary bronchi. There are many nerve endings here that “tickle” before you cough.

Q

The left lung has two of these since it has two lobes. The right lung has three because it has has three lobes.

A

Secondary Bronchi

24
Q

They are smaller tubules that extend from the bronchi. They are no longer lined with cilia. They contain no cartilage and their small diameter prevents their collapse.They are covered by smooth muscle.

25
It is the closing of the larynx by your epiglottis to prevent air from escaping. This can be seen in weight lifting and defecation.
Valsalva Maneuver
26
Which Cranial Nerve Innervates the Vocal Cords?
Cranial Nerve X: Vagus
27
It refers to the rima glottis and the true vocal cords
Glottis
28
Which muscles does coughing use?
Trachealis muscle, the internal intercostals, and the abdominal muscles.
29
There are 300-400 million of this in the lungs and are the branch from the bronchioles. They diffuse oxygen into the pumonary capillaries so it can by carried by erythrocytes to the body's metabolically active tissues
Alveoli
30
They are migratory cells that continually crawl within the alveoli, engulfing microorganisms or particulate material that has reached the alveoli.
Alveolar Microphages
31
it is the potential space in the thoracic cavity when the lung is removed.
Pulmonary Cavity
32
It is the potential space in between the viceral and parietal pleura. It acts as a partial vacuum.
Pleural Cavity
33
It is pneumonia limited to one lobe of a lung.
Lobar Pneumonia
34
Lymphatic drainage of the right lung drains into which lymphatic duct
the right lymphatic duct
35
Lymphatic drainage of the left lung drains into which lymphatic duct
The thoracic duct.
36
It is the opening up and dilation of the bronchioles. It is the main function of the sympathetic innervation
Bronchodilation
37
It is the decreasing of the airway diameter of the bronchioles. It is the main function of the parasympathetic innervation.
Bronchoconstriction
38
encompasses emphysema and Chronic Bronchitis. It is characterized by lung structural abnormalities resulting from inflammation. Airflow obstruction makes it difficult to exhale.
Chronic Obstructive Pulmonary Disease Also known as COPD
39
It is the abnormal collection of air in the pleural cavity that disrupts normal breathing. It breaks the partial vacuum.
Pneumothorax
40
It is a tangled mass of lymph vessels most often seen in young children. It is not cancerous but its growth can encroach on other organs
Cystic Hygroma
41
Excess Amniotic fluid can be a sign of
Muscular Dystrophy, undeveloped brain, or a growth in the chest or neck.
42
the trachea and inserting a plastic breathing tube.
Tracheostomy Piercing
43
collapsed lung
atelectasis
44
accumulation of serous fluid in pleural cavity
hydrothorax
45
accumulation of pus in pleural cavity. occurs with pneumonia
empyema
46
infection of alveoli in the lung. causes tissue swelling and accumulated leukocytes, greatly diminishing capacity for gas exhange. bronchi produce and expel sputum
pneumonia
47
chronic condition with episodes of bronchoconstriction and wheezing, coughing, shortness of breath, and excess pulmonary mucus
asthma
48
why do women who smoke while pregnant have babies with lower birth weight?
umbilical arteries vasoconstrict, decreasing blood flow to the placenta
49
irreversible loss of pulmonary gas exchange areas due to inflammation of the terminal bronchioles and alveoli, as well as wedespread destruction of pulmonary elastic connective tissue. trapped air in nonfunctional alveoli give a barrel chest appearance. cannot exhale properly
Emphysema
50
highly aggressive and frequently fatal malignancy that originates in the epithelium of the respiratory system. metastasis occurs in early stages, making surgical removal of cancer very unlikely. commonly spreads to the brain.
Lung Cancer
51
3 types of lung cancer
squamous cell carcinoma, adenocarcinoma, and small-cell carcinoma
52
most common form of lung cancer. microscopic changes to pseudostratified ciliated epithelium lining the lung to make it sturdier stratified squamous epithelium. become overtly malignant and divide uncontrollably, invade surrounding tissue, and spread to distant sites
Squamous Cell Carcinoma
53
less common that squamous cell type. arises in mucin producing glands in the respiratoru epithelium. DNA injury causes cell to become malignant and divide uncontrollably. histologically indistinguishable from other forms because cells display microscopic features of gland from which it arose.
Adenocarcinoma
54
less common lung cancer originates in main bronchi and invades mediastinum. known for its early metastasis to other organs. arise from the small neuroendocrine cells in the larger bronchi. tumors secrete hormones, such as ACTH, producing symptoms of Cushing Syndrome
Small-Cell Carcinoma
55
research indicates these babies have trouble regulating and maintaing blood pressure, breathing, and body temperature. some form of stress, along with these three factors are involved in deaths. sleeping on stomach increases risk. 60% male
Sudden Infant Death Syndrome (SIDS)
56
Where does most amniotic fluid originate from?
as urine in the fetal kidneys
