Study Notes

Inflammation and Wound Healing

The main purpose of inflammation in vascularized tissues is to protect the body from injury or infection.
Infection, injury, and immune response are all causes of inflammation.
Chronic inflammation typically results from bacterial, fungal, or parasitic infections.
The main process underlying wound healing is the restoration of tissue integrity and function.
The proliferative phase of wound healing involves the replacement of destroyed or damaged tissue by newly produced tissue.
Chronic inflammation is characterized by the presence of macrophages, lymphocytes, and fibrosis.
Rheumatoid arthritis is characterized by symmetrical joint involvement and positive rheumatoid factor.
Redness in inflammation is caused by increased blood flow and vasodilation.
The erythrocyte sedimentation rate (ESR) is a blood test associated with rheumatoid arthritis.
Acute inflammation is characterized by the presence of neutrophils, edema, and pain.
The contraction phase of haemostasis is produced by vascular smooth muscle cells controlled by the vascular epithelium.
Swelling in inflammation is caused by increased permeability of blood vessels and fluid leak.
Pain in inflammation is caused by the release of pain mediators, such as bradykinin and prostaglandins.
Asthma is characterized by airway hyperresponsiveness, obstruction, and mucus hyper-production.
The platelet plug formation during haemostasis is characterized by the formation of a platelet aggregate.
Epithelial-to-mesenchymal transition (EMT) is a process characterized by the transition from epithelial to mesenchymal tissue.
Factors that can delay wound healing include age, diabetes, and nutrition.
The main process underlying wound healing that involves the formation of a fibrin 'mesh' from inactive fibrinogen plasma protein is coagulation.
Platelet-derived growth factors play a role in wound healing by promoting cell proliferation and differentiation.
Medications such as pulmonary rehabilitation and bronchodilators can help slow the progression of cystic fibrosis.
The main purpose of haemostasis in the context of wound healing is to stop bleeding and promote blood clotting.
Diabetes is not a factor linked to chronic wounds.
The main role of fibroblasts in wound healing is to produce collagen and promote tissue repair.
Insufficient fibrosis in wound healing can lead to weakened tissue and impaired wound strength.
Excessive contraction in wound healing can lead to scarring and tissue deformity.
Excessive fibrosis in wound healing can lead to tissue stiffness and impaired function.
Chronic diabetic hyperglycemia can lead to impaired wound healing and increased risk of infection.
Fibrosis is the term that describes the formation of excess fibrous connective tissue in an organ or tissue, typically occurring after severe or persistent tissue injury.
Fibrosis typically occurs in an organ or tissue under circumstances of severe or persistent tissue injury.
Fibrosis is considered a necessary process in certain situations, such as in the repair of tissue injuries.
