Gas Exchange Flashcards
Where do plants obtain oxygen through?
Stomata
Flow of blood to alveolar capillaries
Perfusion
The respiratory pigments if vertebrates
Hemoglobin
The respiratory pigments of invertebrates
Hemocyanin
Refers to the general body surface or skin used by animals with high surface-to-volume ratio
Integumentary exchange
Used by invertebrates that live in aquatic habitats; gills are highly folded, thin-walled, vascularized epidermis that project outward from the body
External gills
Utilizes fine air-conducting tubules to provide gaseous exchange at the cellular level
Tracheal system in arthopods
Thin vascular projection form the body surface of a few amphibians
External gills
Rows of slits or pockets in adult fishes positioned at the back of the mouth such that water enters the mouth can flow over them as it exits just behind the head
Internal gills
Internal respiratory surfaces shaped shaped as a cavity or sac
Lungs
True or false
All lungs receive deoxygenated blood from the heart and return oxygenated blood to the heart
True
True or false
In body tissues, oxygen diffuses from blood→ internal fluid → cells
True
The oxygen diffuses down a pressure gradient from the lungs into the blood plasms -> rbc-> binds to hemoglobin
Oxygen transport
What transport happens when carbon dioxide diffuses down its partial pressure gradient from the tissues into the blood plasma and red blood cells to air in alveoli
Carbon dioxide transport
This controls oxygen and carbon dioxide levels for the entire body by regulating the rate and depth of breathing
Nervous system
A respiratory disorder that the muscles around bronchioles contract more than usual, increasing resistance to airflow
Asthma
This is an abnormal condition of the lungs marked by decreased respiratory function. It is associated with smoking or chronic bronchitis or old age
Emphysema
This is an infectious disease involving inflammation and fluid buildup in the lungs
Pneumonia
