In adult humans, most cancers are carcinomas or adenocarcinomas. These include cancers of the skin, lung, colon, breast, and prostate. Which of the four basic tissue types is involved, and why? a. Connective tissue: it is found everywhere in the body, and is the only tissue common to the skin, lungs, colon, breasts, and prostate. b.

Without macrophages, wound healing is delayed. Why? a. Macrophages phagocytose many foreign materials, as well as cell debris and dead cells. This cleans the wound, allowing scar tissue to form. b. Macrophages form the capillary beds and repair the connective tissue in the wound. Both of these are essential for wound healing. c. Macrophages phagocytose many foreign materials, as well as cell debris and dead cells. This cleans the wound, allowing granulation tissue to form. d. Macrophages break down the scar tissue, allowing the correct tissue to be formed in its place. e. Macrophages only remove the bacteria from the area, preventing infections from causing more damage.
