Cells: The Building Blocks of Life Essay

Water loss is mostly through urine and is also lost in sweat, respiratory tract and feces.Cells are the basic building blocks of life.Electrolytes are minerals in your blood and other body fluids that carry an electric charge.Any loss of water should be matched with a consumption of water on a daily basis to ensure cells receive a constant balance of fluids.The human body is composed of approximately 60% electrolyte-containing water, in which it is the kidneys’ job to regulate.

Give an account of the physiological effect of 3 recreational drugs on the human body

Alcohol would slow down the release of ADH by the pituitary gland, meaning nephrons wouldn’t absorb water and producing more urine.These hormones would make nephron filters to not let water leave our body and pass more water back into blood stream.At the same time some people drink lots of water which it would dilute the salt in blood and the salt level would be lowered to a dangerously low level.So when body needs more water the pituitary gland in our brain would releases vasopressin hormone, this hormone is also called anti-diuretic hormone “ADH”.it will enter our blood stream and dissolve into the bloods water and its blood that transport alcohol to all over the body.

“Explain the concept of homeostasis with reference to the control of heart rate, breathing rate, body temperature and blood glucose levels” Essay

Our body maintains this temperature by balancing the heat we generate compared to the heat we lose in everyday life.The kidneys is where the blood gets filtered while passing through, these molecules are made up from water, glucose, salt and a waste product called urea.The oxygen in your blood will decrease while the carbon dioxide in the blood will increase.It mainly consists of urea but there may be left over water glucose and salts that the body doesn’t need.This means that there will be the right amount of oxygen in the blood on the inhale as a result the right amount of carbon dioxide will come out the blood in exhale.

Water Balance Mechanisms in the Body

Then the kidney takes an action by reabsorbing less water and therefore more water goes in the urine.In the normal conditions water loss is the same as water gain and the water volume of the body remains stable.The pituitary gland which is near the brain checks for the concentration water in the blood and releases the ADH if the blood is short of water.If there’s no ADH our kidneys would just let the water go and high volume of dilute urine will be produced until the water levels turn back down to normal.The water reabsorption does not occur in the ascending limb this is because its walls are impermeable to water.

Function Of The Cardiovascular System

Plasma is made up of about 53-56% blood; it contains proteins, carbon dioxide, ions and blood cells.Following on with the journey, the right ventricle it then flows via the pulmonary artery (this is the only artery that carries de oxygenated blood) the blood is then defused in the lungs and becomes oxygenated.Basically this means that the heat does not have to work as hard to pump the blood around the heart because it is stronger, but it still pumps the right amount of oxygen and blood to the working muscles.It also works by filtering the blood and removing a carefully regulated amount of water and wastes to the lungs working together with the heart, blood vessels, and blood to distribute oxygen throughout the body and remove wastes.But ...

Life Without Gravity Essay

But with everything floating around, I can’t help but think that all that free blood must make you kind of floppy.However, since the only force acting on the cup is the earth’s, pushing everything away from its core, the water probably was already floating around in space somewhere.In 0-g, life would be very hard.So, I wonder how someone, mainly me because I do not have a strong stomach, would merely perform the act of drinking a glass of water and thinking at the same time in a world where everything floats.Not only would the water not be forced to stay in its proper area of residency, the cup, but it would be poured on my face if ever I tried to drink it, and that is most certainly NOT WHERE IT BELONGS.

Chronic Renal Failure Case Study Essay

When a person excretes a large volume of water, the particles are diluted.It then acts on the kidney, increasing reabsorption of water and thereby returning the osmolality of the blood to normal.With excess water intake, the secretion of ADH by the pituitary is suppressed; therefore, less water is reabsorbed by the kidney tubule.(2) Urine Specific Gravity – compares the weight of urine to the weight of distilled water (3) Antidiuretic Hormone – controls the amount of water that is reabsorbed ADH is secreted by the PPG in response to changes in osmolality of the blood With decreased water intake, blood osmolality tends to rise and stimulate ADH release.– by regulating the amount of sodium (and therefore water) reabsorbed, the kidney can...

Kidneys: Function and Structure

.. Because the human body does not maintain a constant water volume, the kidneys have to compensate for the lack of or excess of water consumed.Water is not produced by the body to maintain homeostasis; metabolic water production is simply a by-product of cellular respiration.Water is sourced mostly from dietary intake; this is called preformed water... Water balance is achieved in the body by ensuring that the amount of water consumed in food and drink (and generated by metabolism) equals the amount of water excreted.Simple examples of such disturbances include dehydration, blood loss, salt ingestion, and plain water ingestion.

What is Homeostasis

When we become dehydrated we need to increase the amount of water in the blood: in other words we need to stop water loss.Finally, it is used for the control of the water content of the blood, as we don’t have cells walls like plants it is important we keep the water content at an appropriate level.The ADH increases the permeability of the collecting duct which means that more water can be reabsorbed from the Loop of Henle and back into the blood.Therefore, less water is lost in the urine and more is stored in the body-less water loss which will increase the water concentration in the blood if water is drank afterwards.If we have too much water less ADH is released which means that membranes of the collecting duct are not as permeable so...

Uses of water in living things Essay

Pure water that does not contain any solute is said to be 0 on the concentration gradient scale and so if you were to then add solute to this water you would be decreasing the water potential, essentially making it less than zero and thus ‘more negative’.Water will always move from a region of higher water potential (where there is less solute) to an area of lower water potential to try and counteract the added solute and balance the concentrations.The final use of water in living things that I am going to cover in this essay, and in my opinion the most important, is the role of water in blood and tissue fluid.Osmosis is incredibly important in animal cells, as animal cells will expand when placed in a solution of higher water potential,...
