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.

What is the juxtaglomerular apparatus responsible for?
The juxtaglomerular apparatus is responsible for regulating blood pressure and kidney function. It consists of specialized cells in the afferent arteriole and the distal convoluted tubule that sense changes in blood pressure and help regulate the secretion of renin, which plays a key role in the renin-angiotensin-aldosterone system.
When a person strains to lift a heavy object intrathoracic pressure increases What do you think will happen to the rate of venous blood returning to the heart during such lifting?
The Output (ml/min) of the Left Ventricle increases proportionally (approx.) to the Filling Pressure (that is, the pressure with which the blood returns to the heart), measured with respect to Intrathoracic Pressure. An increase in the latter will then produce a decrease in Cardiac Output, so the rate of blood returning to the heart decreases. That is in the short term. But just after the increase in intrathoracic pressure, the Baroreceptors in the thorax sense the drop in pressure difference and trigger a reflex to increase Heart Rate, in order to restore blood flow. So if the lifting is prolongated, the rate of blood returning to the heart finally comes back to normal level. The opposite reaction is produced when you inhale deeply and hold your breath.
How does water respond to stimuli?
Water does not respond to stimuli in the typical sense as living organisms do. It can be influenced by external factors like temperature, pressure, and contaminants, but it does not have a conscious or biological response to stimuli.
How do pressure receptors in the skin contribute to our sense of touch?
Pressure receptors in the skin, known as mechanoreceptors, detect mechanical stimuli like touch, pressure, and vibration. These receptors send signals to the brain, which processes the information and allows us to perceive and interpret sensations of touch. In this way, pressure receptors play a crucial role in our sense of touch by helping us to feel and respond to our environment.
What is your largest sense organ?
The human body has five sense organs: sight, hearing, touch, taste and smell. The largest sense organ is touch, which involves the skin.
Does the heart pump blood through the lungs?
no it doesnt or you would be breathing in blood and that makes no sense.
When did grasshoppers fly in Pennsylvania?
Your question makes no sense. Grasshoppers can fly, if that's what you're asking.
What sense organ does a sphygmomanometer extend?
A sphygmomanometer, a device used to measure blood pressure, is typically used on the arm. It does not extend an individual's sense organ, but rather applies pressure to the arm to measure blood pressure.
What is carotid baroreflexes?
There are receptors on the lining of the carotid artery that sense a change in blood pressure. When they are stimulated, they can cause a drop in blood pressure/heart rate.
Can a potato have high blood presure?
Potatoes don't have blood, and therefore cannot have high blood pressure. -Sincerely, Common Sense
Do Grasshoppers have a good sense of hearing?
yes, they have ears on the knees
Is a blood pressure reading of 148 over 83 bad?
Itis just at the bottom of the stage 1 high blood pressure chart.
What special sense does grasshopper have?
A special sense helps grasshoppers tell when you are near. Their sense organs are tiny hairs and they listen with their legs.
If a Sikh person sees Muslim blood do they have 2 cut their hair short?
no, why would a Sikh cut their hair if they saw Muslim blood, it doesnt make any sense
Are pets good for lowering blood pressure in adults over 50?
Having a pet in the house can give a person a sense of comfort and provide companionship. This can result is lower blood pressure due to the warmth of giving someone love and affection. It may lower blood pressure and stress.
Can ovarian cysts cause high blood pressure?
Ovarian cysts can cause high blood pressure in the sense that they can cause weaken a person's immune system and cause problems in the long run over time.
