Final answer:
Granulation tissue is a type of tissue that forms during the healing process of a wound. The color of granulation tissue can vary, but it is usually red or pink. If it appears yellow, it may indicate infection or excessive exudate.
Step-by-step explanation:
Granulation tissue is a type of tissue that forms during the healing process of a wound. It is composed of newly formed blood vessels, fibroblasts, and inflammatory cells. The color of granulation tissue can vary, but it is usually red or pink. However, if it appears yellow, it may indicate the presence of infection or excessive exudate.
In terms of stage, granulation tissue is a part of the proliferative phase of wound healing, which comes after the inflammatory phase and before the remodeling phase. During this stage, new blood vessels are formed and the wound is filled with granulation tissue, which acts as a scaffold for tissue regeneration.
