Question

Red blood cell Fibrous clot Neutrophil a. In the following list, number the steps of wound healing after a soft tissue injury. Inflammation occurs in the area as tissue repair begins. Mast cells release histamine that dilates blood vessels and increases blood flow to the repair site, further promoting clot formation. Platelets from torn vessels form a mesh-like clot that prevents blood loss. Neutrophils and macrophages consume bacteria and remove damaged tissue and debris. The tissue created by fibroblasts matures and regains its normal function. Fibroblasts build new tissue by secreting collagen that takes the shape of the original tissue.

Transcript

00:01 The first step is platelets from blood vessels form a mesh like clot that prevents blood loss.

00:11 When soft tissue is injured, blood vessels are damaged which leads to bleeding.

00:16 So platelets are specialized blood cell which respond to the injury by sticking to the damaged blood vessel walls and to each other and form a clot.

00:26 This clot helps to stop bleeding and provide a foundation for subsequent tissue repair.

00:34 In the second step, massed cells release histamine that dilates blood vessels and it increases the blood flow to the repair site, further promoting clot production.

00:48 Massed cells are a part of the immune system and release histamine in the response of tissue injury.

00:57 Histamine causes the blood vessels to dilate leading to the increased blood flow to the injured area.

01:05 This blood flow delivers essential nutrients, oxygen and immune cells needed for the healing process.

01:12 It also contributes to the formation and stabilization of the clot.

01:18 In step number 3, inflammation occurs in the area as tissue repair begins.

01:25 Inflammation is one of the first responses to tissue injury.

01:29 Inflammation is one of the first responses to tissue injury and involves the release of various chemical signals and immune cells to the injury site.

01:43 Inflammatory mediators such as cytokines and chemokines attract immune cells like neutrophils and macrophages to the area...
