It’s not a risk factor
Some reasons for someone to develop DVT?
- Trauma
- Venus stasis, blood is not moving at the proper speed, causing clots
- Damage
- Too many free radicals
What is the result of collapsed bronchi?
They do not collapse; they have rings to keep their shape. Only with a tumor could they collapse.
Why does it lead to alterations of the VQ?
Changes the ability to ventilate, the flow will also reduce. Arteries and capillaries contract, and then the lung pressure is high and could cause right sided heart failure. Pulmonary hypertension
If someone tells your hypertension is classified as essential and idiopathic?

What is the result of gradual venus distention?
Varicose veins
Physiopathology of venus stasis ulcers
When superficial veins start to dialate, it compresses the basement membrane of the skin. The nutrients of the basement membrane cannot go to the surface because it is being compressed, it is not getting proper nutrient and oxygen. Changes in color and later on opens in an ulcer because the skin dies.

What is the definition of a Bulsa
sac
What is the Main reason for atherosclerosis?
plaque formation
Chylothorax happens when?
when lymphatic vessel breaks in thorax
Is Stress a risk for coronary disease?
yes. Stress causes high level of epinephrine which then causes arteriosclerosis (plaque build up in artery)
If someone has collection blood and pus in pleura
hemopyothorax or pyohemothroax
What is a Possible outcome after a prolonged pyothorax, after it has been controlled?
Paquipleuritis (I think this is a Spanish word – paqui means thick)

Why are bradypsychia(slow minded) people at increased risk for coronary failure?
They are not at increased risk for coronary issues
What are some Reasons for someone to develop a Deep Vein Thrombosis (DVT)?
venous stasis(pooling of blood in vein), Or endothelial damage, by trauma or free radicals, which increases coagulation
What is the Name for the oncologic reason that blocks the superior vena cava?
Pancoast syndrome which comes from cancer of the stomach, that effects upper lobes of lung. It Suppresses the superior vena cava, causing high pressure. It can cause damage to upper body tissues and create bulging veins.
How will you define absorption atelectasis?
If bronchiole is blocked it only blocks one aveoli. If bronchi is blocked it blocks a whole lobe of the lung. Absorption Atelectasis is more like the first example.
What is the result of collapsed bronchi?
bronchi don’t collapse because of collagenous rings. (unless steam rolled or run over by an army tank)
What is the Definition of bronchiolitis?
inflammatory airway disease of the smaller airways. Leads to alternation of v/q (ventilation/perfusion ratio)
If pressure in lungs is too high what is the result?
right sided heart failure (Right side is over worked trying to push venous blood in higher pressure pulmonary artery)
Is Hypertension divided into idiopathic and essential? True or false?
False. They are synonyms
Most frequent kind of hypertension?
idiopathic (92-95%)
If One disease process rises the peripheral vascular resistance, what is resulting condition ?
secondary hypertension
When air can enter in the intrapleural space during exhalation what is it called?
does not exist. Air cannot enter intrapleural space during exhalation
Why hypertensive pneumothorax is bad?
person can’t breathe
What is Complicated hypertension?

What is structure of brain that allows inter communication between blood vessels?
willis polygon
What could elevate the content of water in the interstitial fluid on the lung?
lung edema (swelling)
Examples of situations that cause lung edema?
hypertension of the lungs, low level of protein in blood, irritation in the circulation of the lungs vessels causes dilation and becomes more permeable
What is the Result of gradual venous distention?
varicose veins (enlarged and twisted. Seen in older folk)
Explain physiopathology of venous stasis ulcers?
When superficial veins start to dilate, it compresses the basement membrane of the skin. The nutrients from the basement membrane cannot reach the surface because of compression. Because of lack of nutrition skin will change color and die. This causes an ulcer to open in vein.

oxygen poisoning
If oxygen poisoning happens to new born what happens
retrolental fibroplasia
Can pleural effusion lead to atelectasis
yes. Fluid build up will Compress the lung. This is called Compressive atelectasis
