Every cell of our body must need supply of oxygen to maintain its activities. Brain cells are most senstive cells of body.If these cells does not supply with oxygen,ultimately these would die
Humans lose consciousness when the oxygen supply to the brain gets low.
There is a redundant blood supply to the brain to ensure uninterrupted oxygen and nutrient delivery, as the brain is highly sensitive to any disruption in blood flow. The redundancy comes from the two main arteries that supply the brain, the internal carotid arteries and the vertebral arteries, which can compensate for each other if one becomes compromised. This redundancy helps to minimize the risk of brain damage due to reduced blood flow.
neurons die as a result of cessation of oxygen supply and dehydration causes blood viscosity. therefore if blood is viscous there would be poor oxygen supply to the brain because the hemoglobin in the blood carries the oxygen we require for cellular respiration.
It circulates to your brain, but it circulates from your heart.
Yes, CPR continues to supply oxygen to the brain.
The blood vessels around the brain help supply energy for your brain
25% of oxygen goes to your brain
when the heart starts to malfunction, the supply of oxygen to the blood via heart is also impaired, therefore, there is no oxygen supply to the brain which ultimately results in the disfunction of the brain called brain haemorrhage.
The brain lives when it has a constant supply of blood glucose and oxygen.
The brain needs so much blood because it needs a constant supply of it to keep up with the neurons metabolic demands. 20 percent of the blood that comes from the heart is pumped directly to the brain.
The brain !!
because
Brain cells can only survive for 3 minutes without a supply of oxygen.
You are in danger of a stroke
Yes. In fact, such is the brain's demand for oxygen that it requires 20% of your total oxygen supply. This explains why it is served by so many blood vessels.
