what is homeostasis and how it helps to regulate internal environment of an organism

Homeostasis
Definition of homeostasis
Homeostasis is defined as the maintenance of a fairly constant internal environment in an organism.

How does homeostasis work

All living organisms must be able to maintain a steady internal environment.

Generally the body at times is faced with certain conditions that are constantly making it to act in order to keep itself in a steady state and this is where the importance of homeostasis takes place. So in order for the body to maintain a steady flow and constant metabolic operations, the homeostasis environment must be very good


How to know if the homeostatic operations of the body is not in order
At times we fall sick which is an indication of an abnormal condition in our internal environent where the hemostasis is not functioning well

Such abnormal condition requires setting regulation in order to maintain homeostasis


How to correct and maintain interna how to correct and maintain internal processes in body of organisms
Body fluids such lymph, blood and tissue fluids make up the internal environment of the homeostasis of the organism.
The internal environment of the organism must be kept fairly constant for the Healthy growth and efficient functioning of the body cells.

Generally a living organism must be able to adjust to any change in the physical and chemical environment or conditions of his body fluids
This ability to adjust to the homeostasis environment of the body is so important for the organisms to maintain metabolic operations and processes


Some of the conditions are body temperature, pH hydrogen ion concentration, osmotic pressure, concentration of dissolved substances in the body, such as carbon dioxide, oxygen, urea, food substances, e.g. glucose, amino acids and mineral ions such as sodium and potassium chloride

List the main organ and other substances involved in homeostasis
1. The main organ involved in homeostasis is the
kidney,
liver
Skin
Ductless gland like the hormones
The brain
The brain as the major controller of an organism, the brain has the major area where homeostasis takes place in the body it controls the homeostasis process of the body.

In plant, the hormones like auxins helps in maintaining constant internal environment of th helps in maintaining constant internal environment of haemostasis


Osmoregulation or homeostasis in unicellular organisms

Osmo regulations in unicellular 
What is osmoregulation?
Osmoregulation is defined as the process whereby an animal regulate the balance between water and salt in its body fluid
Unicellular organisms such as amoeba and paramecium processes contractile vacuole which enables them to carry out osmoregulations or homeostasis

The cell content of unicellular animals is hypertonic to the external medium, hence water enters to them through a process of osmosis into the cytoplasm and then into the contractile vacuole

In order to prevent the sal in order to prevent the cell from being over turland and land bursting,  the contractile vacuole through Osmo regulation or homeostasis discharges is contents from time to time, maintaining water balance within the organism which is also a balance in Osmo regulation
