The digestive system excretes a solid waste, and the excretory system excretes liquid waste.
Explanation:
The digestive system is the system of the body that breaks down food substances to enhance so that they can absorb them. But it also excretes solid indigestible substances. For excreating, they use the defecation process.
Excretory system, on the other hand, is a system in the body that removes homeostatic wastes from the body by using a process which is called excretion. Excretory includes organs such as liver, sweat glands, lungs. Among this, the liver plays a critical role in the secretion of homeostatic wastes in the form of fluids.
The excretory system collects and then filters excess water which is present in the body and then excretes it as a liquid waste either from the liver, kidneys, or sweat glands on the skin through sweating.
