Answer:
A) areolar tissue soaks up excess fluid in an inflamed area
Explanation:
Areolar tissue is found around blood vessels, muscles, nerve bundles. Edema which is also a part of inflammation occurs when blood capillaries of blood vessels leak the fluid and is soaked by areolar tissue. So excess fluid in these tissue cause swelling of that part.
Edema is one type of defense reaction to the cell injury. With fluid white blood cells and defense proteins move in the area and counter the infectious agent of injury and helps in eliminating the injurious factor. So the correct answer is A.
Answer:
A) A decrease in Na+ permeability, and an increase in K+ permeability.
Explanation:
When the potential action reaches a peak of about +40 mv Na+ channels are open and a high number of Na+ ions are entering the inside of the cell. Shortly after this happens the K+ channels will start to open their gates increasing the cell K+ permeability while the Na+ channels will start to close their gates, so the Na+ permeability will decrease. This happens in order to valance the positive charge on the inside of the cell. Normally the inside has a negative charge while the outside has a positive one, as the inside is more positive due to the increase in Na+ permeability at the beginning of the potential action, K+ cations (which are in abundance in the cell) will have to go out through the K+ channels so as to restore the charge valance, that means that there is an increase in K+ permeability.
