How is a jellyfish alive when it has no heart brain blood etc?
Jellyfish are alive because they grow, reproduce, respire, and respond to stimuli. Simply because an animal or other organism does not have a centralized brain, circulatory system, or even distinct organs does not mean it is not alive.
A jellyfish & a starfish A Jellyfish has no brain & no heart A starfish has no brain & no blood
Jellyfish are extremely simple animals. They do not even have blood, a heart, or even a brain.
No. The blood will stop flowing to the brain and the brain will shut down.
no it does not a jellyfish dose not have a brain heart eyes a skeleton a nervous system or sence of where it is
jellyfish has no brain and heart
"An individual with a completely dead brain can be alive, if the heart is functioning."
well this is the obvious it keeps us alive and living and supplys blood to our brain
Jellyfish have stinging cells in their tentacles, like all cnidarians. They belong in the same group as sea anenomes, coral, and hydras. They have no blood, brain or heart and most reproduce sexually.
No cause it is 95% water and they have no brain and heart
A jellyfish is made up of 95% of water. They can have long tentacles that can be as long as a telephone pole. A jellyfish has no brain,heart, blood,or bones.Jellyfish are not a fish, fish are vertabrates,and jellyfish are in vertabrates.I hope you enjoyed these facts! they are 95% water!!!!!!! i know that's hard to beleave but its true!!!!
the heart pumps blood to support the muscles and kepp you alive the heart pumps blood to support the muscles and kepp you alive
A jellyfish, a seasponge.
Yes. Yes it is.
the heart stays alive by pumping the blood around the body and we bring oxegen in to the blood for our body to stay alive
No it doesn't. It just keeps the oxygen in the blood pumping to the brain - it keeps the body alive. A defibrillator can restart a heart. You need the electrical impulse.
No, they cannot due to lack of blood, a brain, and a heart. They are simply an inanimate object. No need to worry.
The carotid artery takes blood from the heart, up the neck and to the brain and head. The jugular vein takes blood from the brain back to the heart.
No, your brain does not pump your blood. SILLY (: your heart does that job
Blood is pumped to the brain by the heart through blood vessels and capillaries.
Your heart and brain cannot hold all the blood so they blow up
The jugular vein carries blood from the brain towards the heart. It is identifiable in the anterolateral neck.
The jugular veins carry blood from the brain. The carotid arteries carry blood to the brain.
the lungs supply oxygen to the blood and that blood is pumped to the brain by the heart
NO blood is pumped by the heart
The carotid artery is the main artery that carries blood from the heart to the brain. It is identifiable in the anterolateral neck.
heart because if heart is not present in body brain do not get blood and so brain will damage
The heart can remain beating in a person that is brain dead because their heart is not connected to their brain. A person that is brain dead is not necessarily alive because their heart is still beating.
Veins are thin. They carry blood to the heart and brain.
the heart pumps to the brain to keep it going
It circulates to your brain, but it circulates from your heart.
the jugular vein returns un-oxygenated blood back to the heart from the head/brain,the carotid artery takes oxygenated blood from the heart to the head/brain
carotid artery supplies blood to brain jugular vein supplies the de oxygenated blood from brain to heart.
the heart supplies blood to the brain and every other part of the body, and the blood carries oxygen which is consumed to power your body
WhaT is the major distribution sequence of vessels of the arterial blood from heart to brain
Well, depending on where the brain is damaged, the brain controls the heart and the rest of the body so if the part of the brain that controlled the heart or the blood stream got damaged, blood could stop flowing a little and there could be blood clots, causing a heart attack, etc.
The purpose of the lungs are to oxygenate blood. Oxygen is vital for staying alive; so we breathe to bring oxygen into the bloodstream. The purpose of the heart is to pump the blood in a way to oxygenate the body, with the most important area being the brain. It sends the newly oxygenated blood directly to the brain and the rest of the body, and returns the de-oxygenated blood to be re-oxygenated.
The brain does not send the electricity to the heart. The heart is myogenic which means it can contract and relax without any stimulus from the brain.
The heart keeps us alive by pumping blood around the body
i need to know this tooo! The heart pumps blood to and from the brain. I've never heard of the brain pumping blood.
no the brain needs the oxygen from the blood fromt the heart to survive
No blood does not come from the brain. It comes from the heart. It is pumped and some is sent to the brain and other parts of the body.
A heart attack occurs when blood flow to a part of the heart is blocked, usually by a blood clot. Without oxygenated blood, the heart muscle begins to die. A stroke is a brain attack, cutting off vital blood flow and oxygen to the brain. Stroke happens when a blood vessel feeding the brain gets clogged or bursts.

The heart works with the lungs by pumping blood to keep blood pressure down. The heart works with the brain by pumping blood to the cells and neurons to control how you think and act.
You die. Your heart pumps blood thruout your body, blood keeps you alive.
left part of heart
Each beat of the heart pushes blood to the brain. It takes about a minute, or 70 beats to move it throughout your body.
