5 Explain the type of circulatory system and digestive system in animal kingdom.
Answers
There are two types of circulatory systems found in animals: open and closed circulatory systems. In an open circulatory system, blood vessels transport all fluids into a cavity. When the animal moves, the blood inside the cavity moves freely around the body in all directions.
The four basic types of digestive systems in animals are monogastric, avian, ruminant, and pseudo-ruminant. Monogastric animals, such as swine, eat rations high in concentrates. The ruminant digestive system has a large stomach divided into four compartments—the rumen, the reticulum, the omasum, and the abomasum.

Answer:According to the phylum order in the animal kingdom, the phylum Annelida is the first to have a closed circulatory system.
Explanation:Till the phylum Nematoda, they have an “open circulatory system where the exchange takes place through gaseous diffusion and the blood is filled in the hemocoel. From Annelida and then the Arthropoda, Echinodermata, Chordata, all have closed circulatory system. A “closed circulatory system” is marked with the presence of a system of closed blood vessels like arteries, veins, capillaries that carry blood to different parts of the organism.These vessels like in an earthworm are called dorsal and ventral vessels and supplies blood to the dorsal and ventral parts of the body respectively.
