There are two types of circulatory systems open and closed. Please give an example of an organism that has an closed system and one that has an open system. Compare and contrast and open system to a closed system.
Vertebrates, and a few invertebrates, have a closed circulatory system. Closed circulatory systems have the blood closed at all times within vessels of different size and wall thickness. In this type of system, blood is pumped by a heart through vessels, and does not normally fill body. The open circulatory system is common to molluscs and arthropods. Open circulatory systems (evolved in crustaceans, insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.

Open circulatory system Open circulatory system The open circulatory system is common to molluscs and arthropods. Open circulatory systems (evolved in crustaceans, insects, mollusks and other invertebrates) pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.
CLOSED SYSTEM: Many invertebrates do not have a circulatory system at all. Their cells are close enough to their environment for oxygen, other gases, nutrients, and waste products to simply diffuse out of and into their cells. In animals with multiple layers of cells, especially land animals, this will not work, as their cells are too far from the external environment for simple osmosis and diffusion to function quickly enough in exchanging cellular wastes and needed material with the environment.
OPEN SYSTEMS: In higher animals, there are two primary types of circulatory systems open and closed. Arthropods and mollusks have an open circulatory system. In this type of system, there is neither a true heart or capillaries as are found in humans. Instead of a heart there are blood vessels that act as pumps to force the blood along.
The open circulatory system is a system in which fluid (called hemolymph) in a cavity bathes the organs directly with oxygen and nutrients. There is no true heart. Mollusks have these. The closed circulatory system of some mollusks and all higher invertebrates and the vertebrates is a much more efficient system. Here blood is pumped through a closed system of arteries, veins, and capillaries. Capillaries surround the organs, making sure that all cells have an equal opportunity for nourishment and removal of their waste products. the wonderful about.com told me this.
There are two types of circulatory systems open and closed. Please give an example of an organism that has an closed system and one that has an open system. Compare and contrast and open system to a closed system. Closed System: The blood is always enclosed and does not fill cavities in your body. The blood is pumped by a heart. (Humans) Open Sytem: Open systems are found in anthropods. Pump blood into a hemocoel with the blood diffusing back to the circulatory system between cells. Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.
All animals with spines and some without have closed circulatory systems. Humans for example, have closed circulatory systems. Mollusks have open circulatory systems. The difference between the two are in the open system, the blood is pumped throughout the body by the heart and in the closed system the blood is contained in blod vessels.

Humans have a closed circulatory system, while crayfish have an open circulatory system, but what's the difference? Humans blood stays with the blood vessels, but crayfish blood is only partly constrained by blood vessels. Crayfish blood actually fills body cavities, while human blood does not. The tissues in a crayfish are actually surrounded by blood. http://www2.gsu.edu/~bioasx/closeopen.html
Closed System: Most invertebraes have closed systems. Their nutrients and gasses are so close to the enviroment they don't need an open system.
Open System: In more complex animals like humans they have open systems. or as lucas said CLOSED SYSTEM: Many invertebrates do not have a circulatory system at all. Their cells are close enough to their environment for oxygen, other gases, nutrients, and waste products to simply diffuse out of and into their cells. In animals with multiple layers of cells, especially land animals, this will not work, as their cells are too far from the external environment for simple osmosis and diffusion to function quickly enough in exchanging cellular wastes and needed material with the environment.

An organism that has a closed circulatory system is a human. An organism with with an open circulatory is the crayfish. An animal with a closed system has vessels for blood. An animal without one just lets blood flow directly to the the cells, mixing it with interstitial fluid and forming "hemolymph".

Blood is pumped by a heart into the body cavities, where tissues are surrounded by the blood.
Vertebrates and Invertebrates, have a closed circulatory system which have blood closed within the vessels of different thickness. The open circulatory system is very common for Arthropods. Tissues are surrounded by the blood. http://en.wikipedia.org/wiki/Circulatory_system. Also a fish has a closed circulatory system.
There are two types of circulatory systems open and closed. Please give an example of an organism that has an closed system and one that has an open system. Compare and contrast and open system to a closed system.
One animal that has an open CS is a Mollusks or Slug or snails One animal that has a Squid.
Humans, as well as other vertebrates, have a closed cardiovascular system which means that the blood never leaves the arteries, veins and capillaries. Nearly all mollusks have an open circulatory system. An open circulatory system pumps blood by a heart into the body cavities, where tissues are surrounded by the blood.
CLOSED SYSTEM is in vertebrates and invertebrates they have closed blood cells closed all the time within vessels. The vessels are all different sizes and blood is pumped by the heart through vessels. It does not usually fit the body cavities it is pumped in to.
OPEN SYSTEM it is mostly common to mollusks and arthropods blood is pumped from the heart through arteries and blood vessels into things called a hemocoel. Then the blood goes back from there back in to the circulatory system to be pumped into the rest of the body. Then it ends up in body cavities where tissues are surrounded by the blood.
I will compare and contrast an open and closed system.An open system has a heart. A closed system has no heart, it is just a squishy mess. An example of a closed is a grasshopper, but an open system would be a bunny. :)

ReplyDeletea closed system is flushing blood out i think and the open is getting ready to pass on to the closed which sounds like "Lub,Dub"
