The function of the respiratory passageways in humans is to permit the exchange of gases, mainly oxygen and carbon dioxide, between the body and the external environment through the process of respiration.
The main function of the human respiratory passageways is primarily to permit the exchange of gaseous substances, namely oxygen and carbon dioxide, between the body and the external atmosphere. This is achieved through a process called respiration.
When we breathe in, oxygen from the air gets filtered and warmed in the respiratory passageways and reaches our lungs. It then gets transferred to the bloodstream. On the other hand, the carbon dioxide, a gaseous waste product of our body cells, moves from the bloodstream to the lungs, gets expelled through the respiratory passageways when we breathe out.
It's worth mentioning that the other options such as allowing digestive end-products to touch body cells or regulating the amount of ammonia and salt in body fluids are not direct functions of the respiratory passageways.

b. "Her alveoli cannot absorb higher levels of O2 because of the emphysema."
c. "Her alveoli have been damaged and may rupture with higher doses of O2."
d. "Her respiratory center requires low O2 concentration to stimulate breathing."
d. "Her respiratory center requires low O2 concentration to stimulate breathing."
In patients with COPD, the respiratory drive is stimulated by hypoxemia, not increased levels of carbon dioxide. Administration of oxygen in high levels will impair the respiratory drive.
The question is incorrect. The correct question is as follows:
The nurse is orienting a new RN in the care of a patient with respiratory distress due to emphysema. The patient is being treated with O2 via a Venturi mask with 35% oxygen. Which statement by the new RN indicates that teaching has been effective, when the nurse questions the new RN about the use of the Venturi mask?
a. "A nasal cannula will dry the mucous membranes and cause an increased risk of infection."
b. "Her alveoli cannot absorb higher levels of O2 because of the emphysema."
c. "Her alveoli have been damaged and may rupture with higher doses of O2."
d. "Her respiratory center requires low O2 concentration to stimulate breathing."
Answer:
Her respiratory center requires low O2 concentration to stimulate breathing."
Explanation:
COPD ( Chronic obstructive pulmonary disease) may be defined as the combination of the different lung disease that might create problem in the respiration process.
The venturi mask is used in the medical condition to provide the proper amount of oxygen to the patient. In emphysema the individual suffered from the hypoxemia means low oxygen level in the body. The low oxygen is required to the patient and high oxygen level will disturb the normal process of breathing.
Thus, the correct answer is option (d).
Answer:
The correct answer will be option- Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
Explanation:
The humans have always tried to classify organism on the basis of certain similarities and differences of the organisms.
The classical classification system by Carolus Linnaeus classified the organisms in seven hierarchical level but modern classification system by Carl Woese changed it to eight levels system with the, most inclusive group at the top called "Domain" followed by the kingdom, Phylum, Class, Order, Family, Genus and "species" at the lowest level which is the least inclusive group.
Thus, the selected option is the correct answer.
Answer:
kingdom, phylum, class, order, family, genus, and species
Explanation:
The hierarchy of the Linnaeus system of classification begins with kingdom and ends in species with a total of seven taxa. It is best remembered using the mnemonic, King Philip Cut Open Five Green Snakes.
Also, I took a quiz, and this was on it :)
Binomial nomenclature is the formal and accepted naming system used by scientists for naming living organisms. Scientists use binomial nomenclature instead of common names because binomial nomenclature gives distinct (noticeably different) names to a species in a genus. Binomial nomenclature provides every species with a two-part scientific name. The first name is the genus; the name of the small closely related group in which the organism belong to, while the second name is the specific epithet that helps to differentiate and identify a certain species from others that belongs to the same genus.
Common names do not always translate accurately.
Answer:
The correct answer would be 1) a person with AB blood type.
Codominance is the condition in which both the alleles of the gene express themselves completely in the heterozygous condition.
AB blood group can be a perfect example of the codominance. Both the alleles (A and B) express themselves completely and lead to the formation of protein A (or antigen A) and protein B (antigen B) on the surface of the red blood cells.
The correct answer is Robert Hooke.
The invention of the microscope is one of the most essential discoveries ever made by the scientists. Robert Hooke in 1965, witnessed a slice of thin cork beneath the microscope and witnessed minute spaces, which appeared like small rooms combined together.
As they appeared like the tiny quarter of prisoners or monk he named the structures as cells.
This was Scientist Hooke... he was once in jail and that may have been one of the reasons he made the connection to the cells shape and called them what they are today :)
lol we just learned this biology earlier this week and I'm so proud of myself that I remember :)
