In addition to this, osmoregulation is associated with controlling the water content of the body. This is monitored so that cells have protection, not allowing over a certain amount of water to enter or exit them. Therefore, the amount of water content is adequately monitored and controlled through water loss. This can occur through the lungs when the body exhales, the skin when we sweat and the body through urine that is formed by the organ known as the kidneys. Moreover, this also includes controlling the content of salts within the body. It is important that this is controlled for the same reason but instead its processes are different. For example, it is controlled through the loss of ions. This can be done by the skin sweating and the body, once again in urine that is produced within the kidneys. …show more content…

Therefore, without this these would not be able to maintain their functions that are essential in the importance of homeostasis. Moreover, homeostasis is significantly important to the cells of the body as these rely on the movement of chemicals. Chemicals that need to be sent in and out of cells are oxygen, dissolved food and carbon dioxide; this being performed by osmosis and diffusion. Also, osmosis and diffusion rely on the balance of the bodies water and salts, this being another aspect that is maintained by homeostasis. However, the cells rely on enzymes to make the chemical reactions that occur within the body, to keep the cells alive and ensure that it is carrying out it’s functions effectively, speeding it up. Therefore, as we already know, the enzymes work best at 37 dc, which is why homeostasis is important to the cells, ensuring that a constant body temperature

All of our cells, organs and tissues depend on water to help regulate homeostasis. Homeostasis is when our cells seek and maintain a condition of equilibrium or stability internally as it deals with environmental external changes. Because water plays many important roles in the overall maintenance of the body, some of the functions of it include: regulates body temperature, carries nutrients and oxygen to cells, lubricates joints, helps dissolve minerals and other nutrients , and most importantly it also moistens tissues like the mouth, eyes and nose. Dehydration is when the body is deficient in water. Because the water in our bloodstream plays an important role in equally transporting cells and minerals throughout the body, when an individual is not getting enough water the cells in the body will begin to shrivel up and malfunction.

Regulation of ion /acid balances is the responsibility of the kidneys. The kidney can control the excretion of ions such as potassium, sodium, and calcium into the urine. If the ions are higher than normal the kidneys can increase their excretion out of the body to return them to a normal level. The ph balance is controlled by the kidneys ability to monitor and regulate the levels of hydrogen and bicarbonate ions in the

This system interlinks all its components to carry out its function. To determine the functions of the three hormones; renin, angiotensin and how they perform the role of regulating blood volume and sodium balance Body Function: The Renin-Angiotensin- Aldosterone system functions in the regulation of sodium for optimal balance. It also regulates the volume of fluid such as blood and blood

Q1 The organs involved in the homeostatic system of salt regulation are pineal gland, pituitary glands, thyroid gland ,thymus, adrenal, pancreas, ovary and testis. All our bodies removes uneeded fluid by filtering your blood through your kidney, via osmosis, to draw excess water out of your blood. This requires a balance of sodium and potassium to pull the water across the wall from the bloodstream into a collecting channel in the kidney. A high salt diet will alter this sodium balance, causing the kidneys to have reduced function and remove less water resulting in higher blood pressure.

Therefore, the cell needs to maintain its internal environment through osmosis. In a hypotonic solution, osmosis allows water molecules to move from the inside of the cell to the outside, so as to keep the concentrations balanced. In a hypertonic

Osmosis is the diffusion of water through a membrane from an area of high contraction to an area of low concentration. Osmosis happens in three different environments. Osmosis is like diffusion in it requiring no energy. Osmosis can happen in three different types of environments; Hypertonic, Isotonic and Hypotonic. If osmosis were to

Homeostasis is the tendency within every living organism to maintain balance of its internal conditions in order to survive. Some examples of what our body regulates is hydration level, oxygen level, body temperature, blood pressure, and pH balance. The process of maintaining homeostasis comes from two different feedback loops, which are positive and negative feedback loops. A positive feedback loop brings a even greater change in the same direction, when the body senses a change (Raven). A negative feedback loop acts against the change sensed by the body, in order to retain the regular internal condition (Raven).

Looking back to when I was studying GCSE ’s I remember fondly my science classes and recall my enthusiasm to participate and absorb the knowledge being taught by my teachers. These classes exposed me to a lot of different and amazing topics, Homeostasis being one of them which held my attention and curiosity completely. This process intrigued me due to the biological reactions that are linked between every organ, tissues and cells of our body which keep us alive.

The control of blood sugar (glucose) by insulin is another good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels. Once blood sugar levels reach homeostasis, the pancreas stops releasing insulin. In conclusion, homeostasis is the propensity of an organism to regulate its internal environment and maintain equilibrium; usually by a system of feedback homeostasis are the main mechanisms to explain deeply as homeostasis how more related with our daily life

Without enzymes, the pathways of metabolism would become congested because the chemical reactions would take a very long time. Heat can increase the rate of reaction by allowing reactants to attain the transition state more often, but wouldn’t work well in biological systems. High temperatures denature proteins and will kill them, so instead organisms use catalysis to speed up the reactions. The way an enzyme catalyzes a reaction is by lowering the E_A barrier to enable the reactant molecules to absorb energy to react the transition state even at moderate temperatures. Enzymes can’t make endergonic reactions exergonic.

Body systems interact with each other to maintain homeostasis. To start, let 's talk about what DNA actually is. DNA looks like a long spiral staircase. That structure is called a double helix. DNA is located in the nucleus of a cell.

Drive Reduction Theory : Biological or Primary Drives : It means that ,"the source of all behaviour lay in the satisfaction , essential for survival , of the following primary biological needs: hunger , thirst ,need for air , need to avoid injury , need to maintain an optimum temperature , need to defecate , need to urinate , need for rest , need for sleep , need for activity , and need to propagate the species." [Burns,1931, p.107] All of these are important for us in order to live properly. The motivating power of these biological needs is very strong because they are compulsory for us and if we don't complete them, we won't able to live a normal life.
