The lungs are the main organs of respiration | lungs |
The lungs extend from the base of the diaphragm to the apex of the first rib | NA |
The lungs are composed of elastic tissue | alveoli, surfactant, pleura |
Integrity of the airway system is essential for | transporting air to and from lungs |
A properly functioning alveolar system in the lungs oxygenates venous blood and removes carbon dioxide from blood | NA |
The cardiovascular and hematologic systems carry nutrients and wastes to and from body cells | NA |
Inspiration is | the active phase of ventilation; breathe in air |
Expiration is | the passive phase of ventilation; breathe out air |
Refers to the intake of oxygen and release of carbon dioxide | gas exchange |
Gas exchange between the atmospheric air in the alveoli and blood in capillaries | respiration |
Process by which oxygenated capillary blood passes through body tissues | perfusion |
Gas exchange occurs via | diffusion |
Most oxygen (97%) is carried by rbc’s in the form of | oxymemoglobin |
What is the main organ of circulation? | the heart |
The heart has chambers | 4 |
__ atria; __ ventricles | 2; 2 |
The aorta, pulmonary artery (right and left), and pulmonary veins are all | blood vessels |
Dysrhythmia/arrhythmia, myocardial ischemia, angina, mi, and heart failure are examples of | alterations in the cardiovascular system |
Level of health, __, __, __, __, and __ considerations are factors that affect cardiopulmonary and oxygenation | developmental; environmental; medication; lifestyle; psychological |
Bony landmarks and subcutaneous fat become more prominent due to the loss of __ | bony landmarks; subcutaneous fat |
Kyphosis contributes to appearance of | leaning forward |
Barrel chest may result in increased anteroposterior diameter | NA |
Tissues and airways become more rigid in older adults | NA |
