What problem is the cell having if the area around the cells has a high concentration of sodium ions

Sodium ions are kept at low concentrations inside the cell and potassium ions are at higher concentrations. Outside the cell, it is the opposite. When a nerve message is sent, the ions pass across the membrane to send the message. After the message has passed, the ions must be actively transported back to their starting positions across the membrane.

that is true   : ) hope this you

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
