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.
Where does an open circulatory system pump blood or hemolymph into?
In an open circulatory system, blood or hemolymph is pumped into a body cavity called the hemocoel.
Difference in human and worm circulatory systems?
Humans have a closed circulatory system with a heart that pumps blood through a network of vessels, while worms have an open circulatory system where blood is pumped through a simple system of vessels and sinuses by the contraction of the body wall. In humans, blood is confined to vessels, while in worms, blood comes into direct contact with tissues. Humans have specialized blood cells like red blood cells, white blood cells, and platelets, while worms may have fewer types of blood cells.
What organ system transports nutrients metabolic wastes gases and defense cells?
The circulatory system is responsible for transporting nutrients, metabolic wastes, gases, and defense cells throughout the body. This system uses blood as the main transport medium, which is pumped by the heart through blood vessels to reach different tissues and organs.
Deoxygenated blood is pumped through plomonary arties to elsatic saclike structures in the lungs called?
Deoxygenated blood is pumped through pulmonary arteries to elastic sac-like structures in the lungs called alveoli. These alveoli are where the exchange of carbon dioxide for oxygen takes place during the process of respiration.
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

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.
Type of circulatory system in witch blood is pumped through a network of vesselsthat form a closed loop?
closed circulatory system
Where does an open circulatory system pump blood or hemolymph into?
In an open circulatory system, blood or hemolymph is pumped into a body cavity called the hemocoel.
Is a clams circulation open or closed?
Clams have an open circulatory system. Their blood is pumped by a heart into large sinuses through which it bathes the organs directly before being returned to the heart.
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.
What is the path called that blood travels through?
The path that blood travels through is called the circulatory system. It includes the heart, blood vessels (arteries, veins, capillaries), and blood, which is pumped by the heart to deliver nutrients and oxygen to cells throughout the body and remove waste products.
Difference in human and worm circulatory systems?

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
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.
