A systemic lupus erythematosus (SLE) is a condition whereby the immune system attacks the body, confusing it with something foreign. When this patient complains that his hands become pale, blue and painful when exposed to cold, the disease that the nurse should cite in as an explanation for these signs and symptoms is Raynaud's disease. This disease causes areas of your body to numb whenever someone has stress on in the events of being exposed to extreme cold temperatures. The blood vessels narrows and limiting the blood circulation to the affected areas. This effect is called vasospam.
The lungs is your answer :)
All of the above apply to your question
Answer: Homeostasis refers to stability, balance, or equilibrium within a cell or the body. It is an organism’s ability to keep a constant internal environment. Homeostasis is an important characteristic of living things. Keeping a stable internal environment requires constant adjustments as conditions change inside and outside the cell. The adjusting of systems within a cell is called homeostatic regulation. Because the internal and external environments of a cell are constantly changing, adjustments must be made continuously to stay at or near the set point (the normal level or range). Homeostasis can be thought of as a dynamic equilibrium rather than a constant, unchanging state.
Feedback Regulation Loops
The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted. Then, the response to a stimulus changes the internal conditions and may itself become a new stimulus. This self-adjusting mechanism is called feedback regulation.
Feedback regulation occurs when the response to a stimulus has an effect of some kind on the original stimulus. The type of response determines what the feedback is called. Negative feedback occurs when the response to a stimulus reduces the original stimulus. Positive feedback occurs when the response to a stimulus increases the original stimulus.
