Answer:
histamin, wider, swelling
Explanation:
Inflammation is defined as the response of body's immune system to a stimulus (invasion of pathogen or any injury). Some of the inflammatory responses are swelling of wound, redness of wound and itching at injured area et-cetra.
Upon any injury, the injured cells releases a chemical including histamin which causes vasodilation and increased permeability of blood vessels. This chemical recruit white blood cells to the damaged area and initiate the healing process. This chemical allows the local blood capillaries more wider due to vasodilation effect. Under the influence of histamin, the endothelium lining become leaky and allows movement of fluid to interstitial tissue spaces. When the extra fluid moves from capillaries to damaged tissue, it causes swelling or called edema.
The white blood cells initiate phagocytosis of pathogens at injured area and destroy the pathogens. Due to increased pressure from edema and toxins released by pathogens, the pain sensation prolongs, even while the body is repairing the tissue.
Hence, the correct answers are histamin, wider, swelling.
Regular exercise helps make us more alert and energetic, by releasing endorphins which is a chemical that improves our mood.
Answer:
Prophecy.
Explanation:
Self-fulfilling prophecy is a socio-psychological phenomenon of someone predicting or expecting something, positive or negative, and this prediction (prophecy) or expectation comes true simply because one believes it will, and their resulting behaviors align to fulfill those beliefs, including the act of predicting it (self-fulfilling). This suggests peoples' beliefs influence their actions/behaviors. The principle behind this phenomenon is people create consequences regarding circumstances, people or events, based on their previous knowledge toward that specific subject solely based on one’s interpretation of a certain situation. In this case, if the students failed previous math classes, they will fail again because they believe they are going to.
