Final Flashcards
What keeps the trachea from collapsing?
Cartilage
How is the respiratory rate affected with hypoxia and hypercapnia?
Increased respirations
What prevents friction between the pleural membrane
Pleural fluid (serus fluid)
Tidal volume
Normal respiration
Which bronchi is more likely to be occluded with aspiration
Right side because it’s bigger ( has 3 bronchi) (left has only 2)
Normal Ph. What values indicate resp. Acidosis and alkalosis.
Normal: 7.35-7.45
Acidosis: lower than 7.35
Alkalosis: higher than 7.45
What sweeps mucus and pathogens out of the larynx and trachea
Cilia
How would the lungs respond to compensate for metabolic acidosis
Increase respiration to release co2
Where does has exchange occur
Alveoli
What is the primary chemical that regulates respiration in a healthy person
Co2
What surrounds the alveoli
Capillarys
Path of air flow
Nose-mouth-pharynx-trachea-bronchi-bronchioles-alveoli
What is the purpose of the cough reflex
To remove irritants
What are chemoreceptors and where are they located
Chemoreceptors are changes in co2 and o2. Located in Brian (detects o2) And body (peripheral detects co2) (coroided and aortic bodies)
Mediastinum
Area between lungs where heart is
Pleural effusion
Build up of fluid in pleural space. Between visceral and parietal pleural
Tx: thoracentesis
Different blood types
A.B.AB.O.RH+
Donor: O-
Receiver: AB+
What is a thrombus
Blood clot on blood vessel. Forms on ruff area on vessel
Process of clotting. What mineral is needed. what is a clot made of
Process: platelets-prothrombin-thrombin-fibrinogen-FIBRIN
Needs calcium
what blood vessel carries deoxygenated blood from heart to lungs.
Pulmonary artery
What is produced by red bone marrow?
RBC, WBC and platelets
Lymphocytes
WBC that recognize foreign antigens and make antibodies
What types of cell is the precursor to all type of blood cells
Stem cell
What is lymph and where does if flow
Fluid that flows through the lymphatic system
Lymph nodes and where are they located
Cluster of lymph tissue that preform phagocytosis, lymphocytes and macrgocytes
Located: cervical, inganal, thoracic and auxiliary
How does the spleen process old RBCs
By forming billy Rubin
What is hypoxemia and how do the kidneys compensate
Low o2 in blood. So kidneys secret erythropoietin to stimulate RBC
What blood vessels supply the myocardium
Both coronary arteries
What is the cardiac cycle
Atria contracts then ventricles
