What is digestion and how does it work

Biology
1 answer:
slamgirl [31]2 years ago
3 0

Answer:

Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.

Explanation:

Digestion works by moving food through the GI tract. Digestion begins in the mouth with chewing and ends in the small intestine. As food passes through the GI tract, it mixes with digestive juices, causing large molecules of food to break down into smaller molecules. The body then absorbs these smaller molecules through the walls of the small intestine into the bloodstream, which delivers them to the rest of the body. Waste products of digestion pass through the large intestine and out of the body as a solid matter called stool.

GrogVix [38]

Answer:

Overlap to some degree...

Explanation:

The three energy systems work co-efficiently to provide body with energy according to the extent of physical activity. Not only these three system work together but the superpose each other to get the cycle keep on going. ATP is the main energy currency made by these systems. When one system produces enough currency, the same currency is again utilized for body as well as for the system to keep on going. These three systems include The Glycolysis, The Immediate Energy Transfer System and The Oxidative System...

kirza4 [7]

Answer:

They make it themselves! Plants are called autotrophs because they can use energy from light to synthesize, or make their own food source. Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive.

A letter about the evidence of evolution
GuDViN [60]

Answer:

I am writing this in response to a letter regarding evolution. Evolution is increasingly solid, not shaky. Darwin’s “theory” or explanation was a way of understanding what he had discovered (which did not include genes, chromosomes, DNA or nucleotide bases). Our explanations now include genetics and the commonality of mutation.  

Proofs are solid, not in question by serious scientists. Direct observation is one, which we see in the fact that this year’s flu evolved a little too far from last year’s, so flu shots are less effective this year than we would like them to be.  

Fossils tell the story well: whales with legs, dinosaurs with feathers and Tiktaalik. The latter was found in the Canadian north and is part fish, part amphibian, before there were ever any amphibians. Imperfection is a good proof: think of your useless appendix, the very bad design of your ankles, knees, and back (talk to a chiropractor about that).  You have big toes because they used to be useful thumbs for your grasping feet.

Many other animals and even plants similarly have flaws that show their evolutionary past. Two large human chromosomes reflect the coming together of two chimpanzee chromosomes each.

Hope it helps,

Please mark me as the brainliest

Thank you
