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.
Yes, many multicellular organisms have a circulatory system to transport nutrients, oxygen, hormones, and waste products throughout the body. This system helps maintain homeostasis and allows for efficient exchange of substances between cells. Examples include the circulatory system in humans, vascular system in plants, and open circulatory system in some invertebrates.
Actually many single celled organisms do have a water transport system. The contractile vacuole which can prominently be seen in freshwater paramecium is an organelle that excretes excess water outside the cell.
Single-celled organisms (for example, amoebas, euglenas) do not have a circulatory system because they have only one cell, and materials can easily move around the cell without a special system.
They need a circulatory system in order to transport nutrients and waste out of and into cells.

Any organism that has a skeletal system is a...?
multicellular organism
Is a leech a single cell organism?
No, a leech is not a single-cell organism. Leeches are multicellular organisms belonging to the phylum Annelida. They are parasitic or predatory in nature and have a well-developed internal organ system.
What is a good example for unicellular organism and multicellular organism?
You are a good example of a multicellular organism and Escherichia coli, the microorganism living symbiotically in your intestine, is a good example of a unicellular organism.
What involves the movement of materials inside the cell as well as the movement between parts of a multicellular organism?
The processes that involve the movement of materials inside a cell are called intracellular transport, which includes mechanisms like endocytosis, exocytosis, and molecular motor proteins. In multicellular organisms, the movement between different parts is facilitated by the circulatory system (blood vessels and the heart) and the lymphatic system. These transport systems help distribute essential nutrients, oxygen, hormones, and immune cells throughout the organism.
What is an organism that contains many cells?
An organism that contains many cells is called multicellular. Examples of multicellular organisms include animals, plants, and fungi. These organisms are composed of specialized cells that work together to carry out various functions within the organism.
What is the main function of the circulatory system in a multicellular organism?
For non-insects, its the transportation of oxygen and nutrients to the cells and wastes away from the cells.
How do the cells of a multicellular organism function?
The main system that serves the needs of individual cells in multicellular organisms is the circulatory system. This is used to take waste away from individual cells and bring in new fuel such as proteins, glucose, and oxygen.
The fourth and highest level of organization in a multicelluar organism is?
The organ system level is the fourth and highest level of organization in a multicellular organism. At this level, multiple organs work together to carry out specific functions, such as the circulatory system or digestive system.
Any organism that has a skeletal system is a...?
multicellular organism
What is any organism that has a muscular system?
its a multicellular organism
What is the difference between a single celled organism circulatory system and a humans circulatory system?
Unicellular: Exchanges occur directly with enviroment Multicellular: Diffusion is not possible unless diffusion across body surface. Transporting substances over long distance in animals.
What is the function of multicellular organism?
The multicellular organism contains two or more cells. They also own an organ system which contains tissues and organs.
What is the level of organization of a multicellular organism?
an Organ System
How does a multicellular organism obtain oxygen?
multicellular organisms obtain their oxygen through the respiratory system
What are the roles of the circulatory system?
the role of the circulatory system is to transport oxygen and nutrients to all the cells in that one organism
What is the main function of the circulatory system in multicellular organisms?
To transport materials throughout the body.
How does a cell develop into a multicellular organism?
as a multicellular organism develops, its cells as a multicellular organism develops, its cells
