Unit 5 task 3 (P5 M2 D2) – explain the concept of homeostasis‚ discuss the probable homeostatic response to changes in the internal environment during exercise‚ how homeostatic mechanisms control temperature‚ breathing and heart rate and evaluate the importance of homeostasis in maintaining healthy functioning of the body. Homeostasis Homeostasis is the maintenance of a constant internal environment in organisms. It involves volume of blood and tissue fluid within restricted limits‚ it also maintains

may become blurred in some cases blindness. Very high blood pressure can cause a break in a weakened blood vessel which then bleeds in the brain causing a stroke. The organs involved in hypertension are the heart‚ brain‚ and kidneys. The homeostatic imbalance of hypertension is a major cause of heart failure‚ vascular disease‚ renal failure‚ and stroke due to several factors heredity‚ diet‚ obesity‚ age (over 40)‚ stress‚ diabetes‚ and smoking. The feedback system cannot maintain homeostasis in

Mitochondrial DNA. The repairer would be in the mRNA which works the synthesis of proteins that fix the body. E. Joseph’s heart attack has caused the function of his cells to change. What types of proteins in the cell membrane were involved in the homeostatic imbalances of his heart cells? ATP affects the pumping into the membrane by opening ion channels‚ ATPases would affect it in the opposite way because of the lack of ATPases the ATP wouldn’t be taken away. F. Why was reestablishing oxygen flow to Joseph’s

When our body is not able to regulate temperature all our body functions will fail to work. Even the enzymes need a specific constant temperature to work at their optimum level. At higher temperatures the enzymes will stop working. Dialysis is the artificial process

internal environment is maintained by our body. For instance‚ this means that in our body‚ temperature‚ blood sugar levels‚ etc must be kept within a narrow range even when we are in a freezing climate‚ or while doing vigorous exercise etc. All homeostatic control mechanisms have at least three interdependent components which are: The receptor responds to changes in the environment‚ for example‚ detects temperature change. Then‚ after the receptor senses a stimuli‚ it sends information to a ‘’control

The type of proteins in the cell membrane that were involved in the homeostatic imbalances of his heart cells were ATPases‚ and ATP. The lack of ATP affected the membrane pumps‚ and ATPases had stopped moving calcium from the cytosol into the endoplasmic reticulum of his heart cells. 5. F. It was important to reestablish oxygen

obstructive pulmonary disease (COPD) which can be very devastating. During the beginning stages of chronic bronchitis‚ slight coughing may be seen in the morning and as the disease progresses the individual may cough all throughout the day. This homeostatic imbalance causes a build up of excess mucus which in turn causes shortness of breath due to less airflow. Signs of excessive coughing can be seen also some may even see some blood in the mucus. The airway passages start to get inflamed starting with

What types of proteins in the cell membrane were involved in the homeostatic imbalances of his heart cells? Without ATP the sodium potassium ion channels can’t operate. The heart can’t contract properly. Increased Calcium sent the heart in to a prolonged contraction‚ it convulsed recklessly. F. Why was reestablishing oxygen
