Humans maintain homeostasis in many ways.  Below are three examples.

  1. Blood plasma helps maintain homeostasis because the nutrients needed and the waste given off by cells is carried within it.
  2. The lymphatic system helps maintain homeostasis because it collects excess fluid and delivers it to the kidneys. Lymph nodes are also rich in lymphocytes, a type of white blood cell, that help fight infection.
  3. The circulatory system helps maintain homeostasis by supplying all parts of the body with nutrient rich blood.  It also pumps blood through the lungs where gas exchange occurs.

Homeostasis is a concept of maintaining a normal internal environment. Your body does not like change and attempts to maintain the status quo by using feedback loops or mechanisms. A negative feedback loop is a mechanism where your body tries to return everything to normal. The regulation of body temperature is a good example.Let's say you are outside in the summer, it is hot and your body senses this. You start to perspire, when you sweat the liquid covers your body and cools it down thereby lowering your body temperature. Homeostasis is restored and your body is happy.Negative feedback loops are more common than positive feedback loops. An example of a positive feedback loop is uterine smooth muscle contraction during childbirth. The body intensifies the contractions of the uterus to deliver the child.
