Answer:
Atherosclerosis affects arteries, these blood vessels are elastic and flexible in order to allow good blood circulation
Explanation:
The blood vessels are classified into three types: arteries, veins, and capillaries. An artery is a muscular blood vessel that is able to carry blood away from the heart to different parts of the body. Healthy arteries need to be elastic and flexible in order to adjust their diameter and thus control blood flow by maintaining blood pressure. Arteriosclerosis is a chronic disease caused by the accumulation of fatty substances (especially cholesterol) in the artery walls, thereby difficulting blood circulation by thickening and hardening these walls.

Answer:
Volcanoes, burning fossil fuels, and respiration of organisms.
Explanation:
Volcanoes, burning fossil fuels, and respiration of organisms releases carbondioxide that forms atmospheric carbondioxide. The carbon enters in the biosphere through the process of photosynthesis. In plants, carbondioxide enters in the plant body which is used as a reactant from which food is prepared. The carbon present in the plant body in the form of glucose which can be transferred into another organism due to feeding of organisms. The organism released this carbon in the form of carbondioxide when the eaten food is broken down for the release of energy. In that way, carbon moves from biosphere to the atmosphere whereas Volcanoes and burning fossil fuels releases carbon in the atmosphere, in this way carbon moves from lithosphere to atmosphere.
