The respiratory and cardiovascular systems of vertebrate animals work in tandem to transport oxygen to metabolizing tissues and to eliminate carbon dioxide as a waste gas. Which of the following statements accurately describes how these systems interact for gas exchange?
a) The premise of the question is incorrect. The cardiovascular and respiratory systems are completely independently regulated by the body, so that one does not affect the other
b) The rate of oxygen transport by diffusion across the lungs must generally match the rate of transport by the circulatory system.
c) Bulk flow of gases and solutes works well over very short distances, whereas diffusion is effective only over long distances.
d) The rate of gas exchange by diffusion need not match rates of ventilation or circulatory transport.

b) The rate of oxygen transport by diffusion across the lungs must generally match the rate of transport by the circulatory system.

Explanation:

The respiratory and cardiovascular system works sin synchronization with each other to transport oxygen to tissue and eliminate carbondioxide.

example: Exercising skeletal muscles has increased metabolic rate which in turn cause increase requirement of oxygen and as a result increased carbondioxide will be produced.The body will function by releasing local metabolites which in turn effects on heart simultaneously blood vessels will dialates. The heart will pump more blood to deliver the oxygen and nutrient to match the metabolic requirement and will washout carbon dioxide.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
