Answer:
1. Microorganisms capable of causing disease—pathogens—usually enter our bodies through the mouth, eyes, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread—or be transmitted—by several routes.
2. The process of WBCs squeezing out through the walls of the blood capillaries is called diapedesis. Explanation: Most WBC's are amoeboid in nature and can produce pseudopodia with which they can squeeze out of the walls of the capillaries into the tissue known as diapedesis.
3.Large amoeboid cells, that are a part of our innate immune system, found in the areolar tissue are called as: 1. Macrophages.
4.Blood vessels eventually dilate and increase blood flow into the tissue, creating redness in the traumatized area. This is followed by an increase in blood vessel permeability, allowing fluid, proteins, and white blood cells to migrate from the circulation to the site of tissue damage.
