Answer:

Digestive tract & Accessory glands together constitute the digestive system.

Explanation:

The accessory organs are the teeth, tongue, and glandular organs such as salivary glands, liver, gallbladder, and pancreas.

Underneath the right side of the liver, the gallbladder is a pear-shaped organ.

Its primary function is to gather and concentrate bile, a digestive fluid made by the liver. The gallbladder is where bile is kept after the liver produces it. The gallbladder receives a signal from the stomach when you eat. Bile is released from the gallbladder when it contracts, and it travels through the gut via the major common duct. Bile combines with the food there and aids in digestion.

When the gallbladder is removed from a healthy person, there are rarely any obvious health or digestive issues, though there is a slight chance of diarrhea and fat malabsorption.

the repolarization of the cell.

Mechanism :

Action potentials are signals that are sent and received by muscle and nerve cells. Because of the negative concentration gradient in the resting membrane potential of nerve cells, there are more positively charged ions outside the cell than inside. There are more sodium ions outside the cell and more potassium ions within because these positively charged ions are sodium ions. Action potentials cause the membrane to depolarize, which is followed by the process of repolarizing the cell. The membrane potential changes and reverts to the negative value of the resting potential during repolarization. The potassium channels open and the sodium channels close at this stage, allowing the nerve cell to lose positively charged ions.
