Food is ingested.

How will you explain excretion in the digestive system. The process of nutrients being absorbed by each cell of the body in the form of energy. Why do bacteria thrive even in hostile environments. Digestion is a form of catabolism or breaking down of substances that.

Fiber makes you full without over stressing your stomach so it helps you lose weight. It is not the same as Excretion. Through the digestive system nutritive substances are absorbed and any that are not are eliminated.

If you drink a glass of water and then quickly do a headstand your body will still be able to move that water through the digestive system even if you are upside down. Blood part of the circulatory system transports nutrients to other tissues. In plants waste does not accumulate as heavily as it does in mammals and other vertebrates.

This means that they pass through the wall of the small intestine and into our bloodstream. All the food you eat goes through a process with four stepsingestion digestion absorption and elimination. Biology 21062019 23.

The excretory systems function is to remove waste from the body. The excretory system functions in parallel eliminating the by-products of metabolism from the cells throughout the body by its constant cleansing of the blood. The digestive tract begins at the mouth and ends with the anus and includes all the organs in between.

Enzymes are added to the mechanically broken down food from the salivary. The chemical breakdown is when the body makes enzymes chemicals that break food down into small molecules. Like humans vertebrates excrete waste through the skin lungs and urethra with the help of the kidneys and lungs.
