Oxygen and carbon dioxide exchange between the circulatory system and tissues occurs at the?
oxygen and carbon dioxide exchange between the circulatory system and tissues occurs at the capillaries, which are the smallest blood vessels where nutrient and gas exchange takes place through diffusion. Oxygen from the blood is released into the tissues, and carbon dioxide from the tissues is taken up by the blood to be transported back to the lungs for elimination.
What is internal respiration?
the metabolic processes whereby certain organisms obtain energy from organic molecules; processes that take place in the cells and tissues during which energy is released and carbon dioxide is produced and absorbed by the blood to be transported to the lungs
What is anaerobic metabolism?
The body's metabolic process usually involves the oxidation of glucose. When the body cannot get enough oxygen to meet the demands for energy, cells begin using the anaerobic process (without oxygen). This process breaks down glucose and glycogen to lactic acid which then diffuses into the blood stream. The result of anaerobic metabolism can be seen in athletes who are rapidly using energy, at a faster rate than oxygen can be re-supplied to the muscles. Lactic acid build up impedes muscle functions, causing pain and sometimes nausea.
Where does most gas exchange between blood and tissue take place?
Most gas exchange between blood and tissues takes place in the capillaries. This is where oxygen diffuses from the blood into the tissues, and where carbon dioxide diffuses from the tissues into the blood. The thin walls of the capillaries allow for efficient exchange of gases.
In cyanide poisoning levels of ATP in the brain plummet but levels of lactic acid increase markedly why?
In cyanide poisoning, the decrease in ATP levels results from inhibition of the cytochrome c oxidase enzyme in the electron transport chain, impairing cellular respiration. This leads to a shift towards anaerobic metabolism, causing an increase in lactic acid production as cells try to generate ATP through glycolysis in the absence of sufficient oxygen.
Place where blood changes from low CO2 to high CO2?
The blood changes from low CO2 to high CO2 in the tissues where oxygen is delivered and CO2 is produced as a byproduct of cellular metabolism.
Which artery carries blood to the tissues?
All arteries carry blood to the arterioles, which in turn carry blood to the capillaries, where oxygen exchange in the tissues takes place.
What process takes place in muscle cells when they do not get enough oxygen?
Lactic Acid Fermentation

What is the sum of all the chemical processes that take place in an organism?
is called metabolism .
What is the place with the most oxygen on earth?
The place with the highest oxygen levels on Earth is typically at sea level, where the atmosphere is thickest. Rainforests and other dense vegetation areas also produce high levels of oxygen due to photosynthesis.
What refers to all of the biochemical reactions that occur in the body?
Metabolism refers to all of the biochemical reactions that occur in the body, including processes like breaking down food to release energy, building and repairing tissues, and eliminating waste products.
What changes in the composition of the blood take place in the lungs?
Oxygen levels go up while CO2 levels go down. In the lungs, oxygen is absorbed into the blood while carbon dioxide is eliminated through exhaling.
When photosynthesis take place the plant gives off?
When photosynthesis takes place, plants give off oxygen as a byproduct. Oxygen is released into the atmosphere through small pores in the plant's leaves called stomata. This process helps to replenish and maintain the oxygen levels in the atmosphere.
Where does most gas exchange between blood and tissue take place?
Most gas exchange between blood and tissues takes place in the capillaries. This is where oxygen diffuses from the blood into the tissues, and where carbon dioxide diffuses from the tissues into the blood. The thin walls of the capillaries allow for efficient exchange of gases.
