Your body expels sodium in your urine. Your body needs blood pressure and sodium to push waste material through your kidneys and into your bladder. Then when you pee, you get rid of the sodium. You use a certain amount of sodium each day. If you do not get enough, waste builds up in your blood because your kidneys do not work. If you get too much, your blood pressure gets too high and your kidneys do not work so your body does not get rid of waste.

What is the problem when cell expands and bursts because of high sodium ion around outside?
When the sodium ions are in higher concentration out side the cell, the cell shrinks. It does not expand and bursts. It can burst when the sodium ion concentration becomes very low, out side the cell.
What regulates which substances enter and leave a cell?
The plasma membrane. Carrier proteins and ion channels are parts of the plasma membrane, and aid in diffusion across concentration gradients, as most things don't freely move from one end of the cell membrane to the other. The Sodium-Potassium pump is a major ion channel in the plasma membrane, and regulates the intake of potassium and export of sodium (3 molecules sodium out, 2 molecules potassium in.)
Absorption of glucose from the gut lumen depends on?
the sodium-potassium pump in the basolateral membrane of the epithelial cell, cotransporter proteins in the apical membrane of the epithelial cell, and higher sodium ion concentration in the lumen than in the epithelial.
What type of transportation takes place when a protein allows an ion to enter a cell but no additional energy is needed?
facilitated
How does sodium-potassium pump help prevent animal cells from bursting?
the sodium potassium pump uses ATP (energy) to move Na & K in and out of cells. Na is a cation that is found primarily in extracellular fluid and has a strong affinity for water. K is primarily inside of the cells. if there is a build up of intracellular fluid, Na can move out of the cell and bring some water with it, thus reducing the pressure inside of the cell. if a cell is dehydrated and needs fluid, Na can move into the cell and bring water with it, thus rehdyrating the cell. Both Na and K are involved in the electrical potential of cells also.
What is the symbol of a sodium ion followed by the formula of a sulfate ion?
enter the symbol of a sodium ion followed by the formula of a sulfate ion
What is the major positive ion outside of cells?
Sodium is the major positive ion outside the cell. Potassium is the major positive ion inside the cell.
What cells in animal body contain sodium ion?
almost all but some cell does not contain sodium ion.
What is the problem when cell expands and bursts because of high sodium ion around outside?
When the sodium ions are in higher concentration out side the cell, the cell shrinks. It does not expand and bursts. It can burst when the sodium ion concentration becomes very low, out side the cell.
Which describes the ion concentrations inside and outside of a neuron?
The sodium ion concentration is higher on the outside of the cell and potassium ion concentration is higher on the inside of the cell
What is the change of ion pump to move ion across the cell membrane?
Sodium Potassium pump
How does sodium ion molecule move into the cell through cell membrane?
Through diffusion.
What substance crosses the cell membrane by facilitated diffusion?
a sodium ion
What is the physical mechanism leading to the electrical impulse action potential in an axon?
It is called depolarization and happens when sodium and/or calcium ions enter the cell rapidly through their respective voltage-dependent ion channels or potassium ions stop leaving the cell through their ion channels or chloride ions stop entering the cell through their ion channels.
What regulates which substances enter and leave a cell?
The plasma membrane. Carrier proteins and ion channels are parts of the plasma membrane, and aid in diffusion across concentration gradients, as most things don't freely move from one end of the cell membrane to the other. The Sodium-Potassium pump is a major ion channel in the plasma membrane, and regulates the intake of potassium and export of sodium (3 molecules sodium out, 2 molecules potassium in.)
What is a component of an animal nerve Cell membrane?
A component is the Sodium ion channel.
What transfers the nerve impulse from one neuron to another cell at the synapse?
When the sodium ions that entered the cell through the ion channels diffuse into the axon terminal of the neuron, they activate voltage-gated calcium ion channels. As calcium ions flow into the cell, neurotransmitters are released from the cell. These neurotransmitters diffuse across the synapse and activate sodium ion channels in the post-synaptic cell, allowing sodium to flow in and depolarize the cell enough to start another action potential.
