Drowning in salt water and fresh water is different, even though you would think it would be the same. Only around 10% of people who drown will drown in salt water, the other 90% drown in fresh water; more specifically, they drown in swimming pools. A person drowning in salt water can be dead from anywhere between five and thirty minutes, while in fresh water it can take anywhere between five and twenty minutes. That’s a ten-minute difference and it’s a big difference. So, why does it happen like this? Why can a person be more likely to drown in fresh water, which is generally more controlled than salt water? Why is there a ten-minute drowning difference? It all has to do with osmosis, both of the solutions react different with our bodies. …show more content…
In lecture, we learned that hemolysis is what occurs when a blood cell comes into contact with a hypotonic solution. Also, that hemolysis is defined as the swelling and rupture of the blood cells. In lab, we tested how distilled water reacts with the blood cells; as we watched the cells, we could see them starting to swell and burst one by one. When we observed this, we knew right away that it was hemolysis, and that distilled water was hypertonic to the cells. When you are drowning and the fresh water gets into your lungs, it immediately starts to cause damage to your cells, not just your blood cells but your lung cells too. When water comes into contact with your lung’s cells, it rushes in trying to balance out the concentrations causing them to blow up. The end result of this process is cell rupture because once a cell reaches its full capacity it burst when you try to go beyond that. Not only are your lung cells effected but so are your blood cells. This is where hemolysis comes in, “Because capillaries in your lungs are exposed to the fresh water, water enters the bloodstream” (Why It's Worse to Drown in Fresh Water Than Salt Water), when this occurs your blood cells react the same way by blowing up and bursting. The bursting blood cells can cause you to go into cardiac arrest anywhere between two to three minutes, much faster than
Many have been told to follow the eight x eight dictum, but as said in the article no scientific studies support that notion. It's even said that doing that can be harmful to you. The way water is dangerous too you if overdone, is the kidneys cannot flush it out fast enough and the blood becomes waterlogged. This can result in your cells swelling to accommodate all the water. The real danger though is hyponatremia, where the cells reach the brain and neurons, and when your neurons become waterlogged it can be very dangerous as said in the article “hyponatremia causes entry of water into brain cells leading to brain swelling, which manifests as seizures, coma, respiratory arrest, brain stem herniation and death”. Proving further that water can be
When the cell has all the water it can take inside of it the osmosis
Also, hypoxia, which is a lack of oxygen, is another pathological physiological outcome of sepsis as less oxygen is reaching the tissue; this is due to the fact that there is less oxygen in the blood.
Deep water and strong currents could lead to drowning. - stay away from the sea.
As Marc is dehydrated, he would be experiencing a water imbalance throughout his body. This would make his body complete the process of osmosis. In osmosis, water molecules move from an area of high concentration to and area of low concentration. In this instance, the body cells would be the area of high concentration because they have more unbound water molecules. Since the solute level is higher than water in his blood and fluids, this is the area of low concentration. This would cause a number of water molecules will diffuse form inside of the cell to outside of the cell. This process of osmosis will continue until the
Here, deep in the lungs, oxygen diffuses through the alveoli walls and into the blood in the capillaries and gaseous waste products in the blood—mainly carbon dioxide—diffuse through the capillary walls and into the alveoli. But if something prevents the oxygen from reaching t...
Hemodialysis is a procedure that cleans and filters your blood. It rids your body of harmful wastes and extra salt and fluids. It also controls blood pressure and helps your body keep the proper balance of chemicals such as potassium, sodium, and chloride.
Water and Salt water sound similar, at first you would think that but as soon as you research either of them you’ll find that the only thing they have one thing in common water. This pair brings to mind somewhat of a similar situation in golf and frisbee golf. One would think that you frisbee golf is just golf with a frisbee but this is not so it s deeper than that. When you experience both of these it come to you, although they share similar names golf and frisbee golf have many differences between them.

Alveolar hyperventilation causes a decreased partial pressure of arterial carbon dioxide (PaCO2). The decrease in PaCO2 increases the ratio of bicarbonate concentration to PaCO2 which increases the pH level. The decrease in PaCO2 develops when a strong respiratory stimulus causes the respiratory system to remove more carbon dioxide than is produced. Respiratory alkalosis can be acute or chronic. Acute respiratory alkalosis is when the PaCO2 level is below the lower limit of normal and the serum pH is alkalemic. Chronic respiratory alkalosis is when the PaCO2 level is below the lower limit of normal, but the pH level is relatively normal or near normal. Respiratory alkalosis is the most common acid-base abnormality observed in patients who are critically ill. It is associated with numerous illnesses and is a common finding in patients on mechanical ventilation. Many cardiac and pulmonary disorders can occur with respiratory alkalosis. When respiratory alkalosis is present, the cause may be a minor or non–life-threatening disorder. However, more serious disease processes should also be considered in the differential diagnosis (Byrd, 2017). Hyperventilation is most likely the underlying cause of respiratory alkalosis. Hyperventilation is also known as over breathing (O’Connell, 2017).
Freshwater fish and saltwater fish are very similar in a lot of ways, but also have differences between them so you can tell them apart. Marine water (saltwater) equals over 96 percent of the water on Earth and over 70 percent of Earth’s total surface. Freshwater is less than four percent of Earth’s total water and is about one percent of Earth’s surface (Freshwater Fish). Interestingly a few species of fish can live in either freshwater or saltwater, but for the majority, they must live in a specific environment. All species of fish used to live in a saltwater environment until certain geological events (earthquakes, volcanic activity, etc.) occurred, creating conditions that isolated groups of fish. The new habitats, included freshwater, and new food sources caused fish to either adapt, or to die (Lohrey).
When more water leaves the body then comes in, dehydration is occurring ("Safe Drinking Water: Tap Water, Bottled Water, & Water Filters.”). Without the water you need you can’t regulate your body temperature and your body can’t lubricate you joints ("Athletes: The Importance of Good Hydration.”). Being a dehydrated athlete won’t let you preform at your highest level ("Athletes: The Importance of Good Hydration.”). Because being hydrated helps transport nutrients to give you energy and keep your body healthy ("Athletes: The Importance of Good Hydration.”). It may cause you to experience fatigue, muscle cramps, and dizziness ("Athletes: The Importance of Good
Ocean water is often referred to as salt water. Ocean water becomes salty as water flows in rivers, it picks up small amount of mineral salts form rocks and soil of the riverbeds. This very-slightly salty water flows into the oceans. The water in the oceans only leaves by evaporating, but the salt remains dissolved in the ocean, it does not evaporate. So the remaining water gets saltier and saltier as time goes on.
If there is not enough oxygen in the water, it may lead to the death of many organisms, reduction in their growth or even failure to survive. The pH is a measure of how acidic or alkaline the water. It is defined as the negative log of the hydrogen ion concentration. According to Fondriest Environmental Inc, a well-known Fundamental Environmental organization, the pH scale goes from 0 to 14. As the scale of pH decreases, water becomes more acidic. Many chemical reactions inside aquatic organisms are necessary for survival and growth of organisms. At the extreme ends of the pH scale, (2 or 13) physical damage to gills, exoskeleton, fins, occurs. Changes in pH may alter the concentrations of other substances in water to a more toxic form. Examples: a decrease in pH (below 6) may increase the amount of mercury soluble in water. An increase in pH (above 8.5) enhances the conversion of nontoxic ammonia (ammonium ion) to a toxic form of ammonia (un-ionized ammonia). (Fondriest,
Soil salinity is said to be “bad” for plant growth but is this really true? Is it just a big misunderstanding? Is it really the salts 'fault'? Are there no solutions to fixing this problem? These are some of the questions many people should be asking before deciding if salt is a friend or foe. Instead of just following whatever others say, people should know exactly how soil salinity is affecting crops and why this is happening. To know our enemy, in this case 'the salt', experiments has to be done, results must be gathered and processed and there must be an explanation to understand the different outcomes and results. We decided to find out everything about soil salinity and how it affects plant growth because plants are a huge part of our life, we live and breathe because of them and we want them to flourish. First, these are some information and questions that will make it easier to understand the whole concept altogether.
