because multicellular organisms cannot survive on diffusion alone. as a result, they need these mechanisms to transport nutrients and substances through the body
multicellular organism
Oseberg Transport System was created in 1988.
nervous system
You have to talk about the differences and similarities they have in common in the transport system.
Large animals require a circulatory system so that they are able to efficiently distribute materials throughout their body. The circulatory system consists of the heart, blood vessels, blood, lymph, lymph vessels, and associated organs such as the thymus, spleen, and liver. Various functions include: transport of nutrients from the digestive system and storage depots to each cell, transport of oxygen from respiratory structures, transport of metabolic wastes from cells to excretory organs, transport of hormones, helps to maintain fluid balance, distribute metabolic heat, maintain the approprate pH and help defend against invading microorganisms.
To transport materials throughout the body.
multicellular organisms obtain their oxygen through the respiratory system
They don't do that. That is the role of the operating system.
why is circulatory system known as transport system
electron charge transport system and regulatung enzymes
They don't have any transport system
a sponge does not have a nervous system
an Organ System
