These features are brought about through chemical/inflammatory mediators released from damaged tissues. The main effects of these mediators are on the blood supply, causing vasodilation (redness and heat) and increased blood vessel permeability that allow plasma proteins and immunoglobulins to pass easily into the tissues. “Pressure or nerve endings from the interstitial fluid and the effect of some inflammatory mediators such as substance P and prostaglandins that cause pain” (Dobson, 1999). In our case inflammation of a toe might be acute or chronic. Acute inflammation is a rapid response to an injurious agent that serves to deliver mediators of host defense—leukocytes and plasma proteins—to the site of injury.
• Acute sequestration event occurs when blood flow from an organ such as the liver, lungs, or spleen is obstructed by sickled RBC. with potential respiratory failure. • Aplastic event occurs when there is an increased destruction or decreased production of RBCs. 3. What other assessment data would the nurse have to
2. Many factors may affect fluid input and output medical conditions such as congestive cardiac failure, renal failure, high sodium intake and cirrhosis of the liver. Also the type of anaesthesia used will contribute to the input/output of fluids. Wound drainage could be affected if the patient has an un-diagnosed clotting disorder, infection, or an amniotic embolism. A patient who has had multiple surgeries could also cause a lot of tissue damage and could increase the patients blood loss.
Cerebrovascular Accident By Mike Smith RADT153 Radiography Patient Care Cypress College Just what is a cerebrovascular accident (CVA) one might say? A cerebrovascular accident otherwise known as a stroke occurs when the blood supply leading to the brain is interrupted or reduced; causing the tissue in the surrounding area to become oxygen deprived, which can lead to brain damage. This can be caused either by a type of blockage, known as ischemic stroke or by a rupture in a blood vessel, a hemorrhagic stroke. There is also a condition called a transient ischemic attack, where the individual for a brief period of time shows symptoms that are similar to a stroke. About 85 percent of strokes are ischemic strokes (Stroke, 2014).
Now i am a scientist- what can i test? Now i am a scientist- what can i test? Name: Chloe Hammond Introduction: (400 words excluding the hypothesis) Splatter patterns are blood spatters at the scene of a crime can be useful in reconstructing what and how events took place by determining the location of the source of the blood source or the direction of movement. Blood spatter can also help determine whether a person was at the crime scene during the offense. There is a very basic classification system of spatter patterns, which is based upon the velocity of the object causing the impact upon the blood source and the size of the resulting blood pattern or spatter evidence.
The homeostatic imbalance that causes hypertension is a possible reaction to medication, or a shock. Also weight is a factor, and inactivity. Other factors are drinking and smoking. Internal and external stressors also affect homeostasis, which in turns causes Hypertension. The organ system it involves is the cardiovascular system.
If a blood vessels bursts this is called a stroke. The blood becomes sticky because the amount of sugar and fats that have been released into the blood to try and respond. Stress can be linked with many problems such as eczema, depression and stomach. There are different ways to manage stress and this can be from medication to exercise. The human body is designed to know when stress is used and is effecting the body and your body should know how and when to react to it.
WRITE A CONCLUSION IN WHICH YOU EXPLAIN IN ONE PARAGRAPH WHAT YOU HAVE LEARNT IN DOING THIS ASSIGNMENT AND HOW IT HAS CHANGED THE WAY IN WHICH YOU WILL VIEW LIFESTYLE DISEASE OR BEHAVIOUR IN THE FUTURE FROM THIS ASSIGNMENT, I HAVE LEARNT THAT BLOOD PRESSURE IS THE PRESSURE THE BLOOD EXERTS AGAINST THE BLOOD VESSEL WALLS AS THE HEART PUMPS. THE PRESSURE INCREASES WHEN THE HEART CONTRACTS AND PUSHES BLOOD INTO THE VESSELS AND LOWERS WHEN THE HEART RELAXES, BUT THERS ALWAYS A CERTAIN AMOUNT OF PRESSURE IN THE ARTERIES. BLOOD PRESSURE CHANGES FROM MINUTE TO MINUTE AND IS AFFECTED BY ACTIVITY AND REST, BODY TEMPERATURE, DIET, EMOTIONAL STATE, POSTURE, AND MEDICATIONS. I HAVE IN CONCLUSION LEARNT THAT I NEED TO TAKE MUCH MORE CARE OF MY OWN PHYSICAL CONDITION. INDICATE AT LEAST 5 REFERENCES THAT YOU HAVE USED IN THIS

Some examples of DNA use for forensic investigation is Identify potential suspects whose DNA may match evidence left at crime scenes Exonerate persons wrongly accused of crimes Identify crime and catastrophe victims Establish paternity and other family relationships 2. DNA identification can be quite effective if used intelligently. Portions of the DNA sequence that vary the most among humans must be used; also, portions must be large enough to overcome the fact that human mating is not absolutely random. 3.
This information sheet is based on the available research and current clinical practice. What are the risks? Whilst some objects pass through the body without harm, pica can potentially be life threatening. Risks include vomiting, constipation, infections, blockages in the gut and intestines, choking and poisoning. Sometimes surgery is needed to remove objects from the gut or to repair damaged tissue.
