What is it?
Negative Feedback loop
A negative feedback loop is when the body Takes measures to reduce a stimulous
E.g. Blood sugar regulation (insulin lowers blood glucose when levels are high ; glucagon raises blood glucose when levels are low)
The body's reaction to too much water
When you have too much water in the body, the kidneys can't remove the excess liquid. It starts collecting in the body, leading to nausea, vomiting, and diarrhea. These are all caused by the body's need to flush out the exes water.
Too much water
The bodys reaction to too little water
Too Little water
If you don't get enough water, hard stools and constipation could be common side effects, along with abdominal pain and cramps. Dull skin. Dehydration shows up on your face in the form of dry, ashy skin that seems less radiant, plump and elastic Fatigue is also a symptom.
Homeostasis
a self-regulating process by which biological systems maintain stability while adjusting to changing external conditions.
This is maintained by osmoregulation, thermoregulation glucoregulation and more.
Homeostasis
What is it?
Posotive feedback loop
When the body Takes measures to increase a stimulous
E.g. When a mother is in labor the baby's head pushing on the cervix signals the brain to release oxytocine, this creates more contractions therefore making the baby's head push out further.
Feedback loop
The feedback response of the regulation of osmolality
Not Enough water in the blood
stimulous
Baroreceptors detect fall in blood preassure and volume
receptor
osmoreceptors detect increases in osmolality
The Brain
Cells in Kidney
modulator
The hypothalamus and pituitary gland
Effector
effector
the hypothalamus
Cells in the distal Convoluted tubule and collecting duct
Response
response
Alteration in the reabsorption of water wich changes the osmolality of blood and blood preasure and volume
Functions of water
Other Functions
Of water
Osmoregulation contributing to thermoregulation
redistributing heat from active tissues to the skin and cooling the body through perspiration
Keep a normal body temprature
Osmoreguation Asistance to the Extretory system
Excretory Ststem
Adequate water intake enables your body to excrete waste through perspiration, urination, and defecation. The kidneys and liver use it to help flush out waste, as do your intestines.
Nutrients transport
Water allows these nutrients to pass through the capillaries within the intestinal walls to the blood and circulatory system where the valuable nutrients and oxygen can be distributed throughout the body to all the cells and organs.
Carries nutrients and oxygen to cells
Benifits and disadvantages of a model
Benifits:
Models can help with improving explinations, provide visual representation, help make a mental model of systems and generate discussions about the topic
Disadvantages:
Models can oversimplify explinations, miss many details and only represent aproximations.
