Mark Foust AP2630 Unit 7 Assignment 1: Urinary System Homeostasis Due Date: November 4‚ 2014 Homeostatic Imbalances a Person on Dialysis Might Face Homeostasis is extremely important for proper functioning of all the human body systems. 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

Anatomy & Physiology P5‚ M2 & D2: Explain the concept of homeostasis and discuss the probable homeostatic responses to changes in the internal environment during exercise In this assignment the concept of homeostasis will be explained and the probable homeostatic responses to changes in the internal environment during exercise will be discussed. Homeostasis is simply how the body keeps conditions inside the same. It is described as the maintenance of a constant internal environment.

blood supply to create new cells. Mitochondria contains its own DNA and genes so it can replicate. 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? 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

DNA. The instructions his body needs to repair itself‚ would be in the mRNA‚ which directs the synthesis of specific proteins that will aid in repairing the body. 4. E. 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

Joseph’s Story Jalisa Cason A&P 1 Unit 2 case study B. Cellular processes and membrane functions that will be affected if Joseph’s heart stopped would be as follows. Oxygen‚ glucose‚ and essential ions that are required for the heart to pump will slow down. Each of his cells will have to work harder and faster which uses up his energy supply. Carbon dioxide levels inside the cells will rise‚ which causes his PH to drop. The mitochondria will run out of oxygen and glucose to make essential ATP

Identify how his risk factors would affect cellular function. Joseph’s risk factors include family history of vascular disease‚ his diet‚ smoking cigarettes. His risk factors would affect cellular function greatly because of the strain it puts on the heart. B. Assuming Joseph’s heart has stopped‚ what cellular processes
