Why doesn't it make sense for grasshoppers to have high blood pressure?
Grasshoppers have an open circulatory system. This means that blood (which, in insects, is called haemolymph) is pumped by the heart straight into sinuses that surround the grasshoppers muscles, tissue, and organs. Unlike us humans who have closed circulatory systems, blood isn't delivered throughout the body in blood vessels like veins and arteries (except for the aorta). When blood is delivered through vessels throughout the body, there is a force exerted on the vessel walls. This force is called blood pressure.Grasshoppers don't have blood vessels throughout their bodies; all they have are the heart and aorta. Blood goes straight from the sinuses in the grasshopper's into the heart, and is pumped straight out of the aorta into the sinuses. The only pressure exerted is on the short aorta leading out of the heart-- and that's it. Because of this, they cannot have high blood pressures.I'm not 110% sure if that's all correct, but I hope it helps. I'm doing a biology assignment on the circulatory system of grasshoppers for high school right now, and I was looking for some answers myself... sucks when no one answers though, haha.
Why does an earthworm have an open or closed circulatory system?
Earthworms have a closed circulatory system. Blood is pumped throughout its body by ringed blood vessels. An open circulatory system is not contained in vessels. In a closed circulatory system oxygen is carried in blood! hope this helps=)
Deoxygenated blood is pumped through plomonary arties to elsatic saclike structures in the lungs called?
Alveoli
Where does blood travel in your body?
The heart pumps blood through blood vessels. Blood vessels leaving the heart are called arteries, and the blood vessels returning to the heart are called veins. Connecting the arteries and veins are smaller blood vessels called capillaries.It's pumped around through tubes called veins and arteries by the heart.The circulatory system is basically a closed network of tubes. The heart muscles contract, which squeezes blood into the arteries. There are valves in arteries and veins to stop the blood flowing 'backwards' - and so, with each heartbeat, the blood is forced forwards through the circulatory system before returning to the heart to start again.
What systems share the responsibility of supplying cells of the body with oxygen and disposing of carbon dioxide?
The blood (circulatory system) carries oxygen to your lungs (respiratory system). Oxygen binds to the hemoglobin molecule in your blood and is carried back to the heart, then pumped out to the other parts of the body.
In the open circulatory system of some mollusks blood is found in?
Mollusks which have an open circulatory system, have blood that is pumped into sinuses containing tissue.
Type of circulatory system in which blood is pumped through a network of vessels that form a closed loop?
Closed circulatory system or sometimes called cardiovascular system
Type of circulatory system in witch blood is pumped through a network of vesselsthat form a closed loop?
closed circulatory system
Do humans have an opened or closed circulatory system?
Humans have a closed circulatory system, in which blood is pumped by the heart through dedicated vessels, where it stays contained, as opposed to an open circulatory system (usually found in invertebrates) where blood is pumped out of the heart and vessels.
How does the veins do for the circulatory system?
The veins provide the conduits for blood to return to the heart from the body after it is pumped out into the body through the arteries.

How does the circulatory help us?
The Circulatory System helps us by your body needing cells. Also nutrients and oxygen removes waste from your body.As blood is pumped out of the heart it travels through arteries capillaries and then veins.
What is blood pumped from the heart to different parts of the body called?
its part of the circulatory system that the heart pumps blood to all parts of the body
Do birds have single or double circulatory systems?
In a single circulatory system blood is pumped from the heart to the gas exchange organ and the to the rest of the body. In a single circulatory system low blood pressure is maintained. Blood travels to organs more slowly. In a double circulatory system blood is pumped from the heart to the gas exchange organ and again to the heart and from the heart the blood is pumped to the rest of the body. In a double circulatory system high blood pressure is maintained as blood must be pumped at a faster rate to the parts of the body. blood travels more faster to organs Animals with single circulatory systems, e.g:Fish Animals with double circulatory systems, e.g:Humans
Do butterflies have closed circulatory systems?
The butterfly's circulatory system consists of a long tubular heart and hemocoel (spaces between organsfor blood to move). The blood is pumped out to tissues through the hemocoel, but it simply seeps back through the tissue, and it doesn't carry oxygen, just nourishment. Air enters through pores called spiracles and moves through tubes through the body, with gas exchange occurring at the ends of those tubes (tracheae).(see links below for more information.)
What is the difference between the transport system of plant to the transport system of animals?
Plants really don't have a circulatory system. Water and nutrients move through a plant by simple physics. It's not pumped anywhere like an animal's circulatory system is.
What is open circulatory system?
An Open circulatory system is one in which the flow of blood/hemolymph is from the heart to the peripheral organs then to the body cavity. There is no system of veins to carry the blood back to the heart. This is the arrangement in mollusca.http://www.answers.com/circulatory+systemjust go to wikipedia and type: Open Circulatory system
