Patients with hypertension need to limit and even cut down on their salts because salt draws out a lot of water. So the result of this would be the cells shrinking and then being crenated which would also lead to the effects of having hypertension.

This can cause higher blood pressure as cells along veins shrivel up the pathways for red blood cells causing higher blood pressure when blood volume increases.]]> 2021-02-13 15:43:06 UTC https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1199403724 https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1200135055 In our body, there are plenty blood cells. The red blood cells has a higher water potential when compared to outside the blood cells which has a lower water potential because of higher salt concentration. Thus, water molecules move from the partially permeable membrane of the cell(higher water potential) to outside the cell(lower water potential) to equalise water potential through the process named osmosis. This leads to excessive water to be drawn out from the cells to the vessels. The blood cells to shrink and die due to excessive water loss. Multiple blood cells will be lost. Decreased blood volume leads to low blood pressure(hypotension). To equalise the blood flow around the body the heart has to pump faster thus leading to high blood pressure(hypertension). Excessive salt intake can lead to high blood pressure (hypertension), which stiffens and narrows the blood vessels. Blood and oxygen flow to key organs decreases. So the heart tries harder to pump blood throughout the body, which further increases blood pressure.
Kidney's function is to remove fluids(e.g.water). Excessive water in the vessels are needed to be removed by the kidney. To complete this function the kidney cells needs oxygen. Oxygen is transported by the red blood cells. When the blood cells volume decrease, the heart needs to pump more harder to transport blood faster,around the body, increasing blood pressure.
American Heart Association recommends no more than 2,300 milligrams (mgs) a day and an ideal limit of no more than 1,500 mg per day for most adults, especially for those with high blood pressure.

Effects of high blood pressure: 

• Heart attack or failure
• Stroke
• Weakened and narrowed blood vessels in your kidneys.
• Thickened, narrowed or torn blood vessels in the eyes.
• Metabolic syndrome
• Trouble with memory or understanding.
• Aneurysm

Hence, the red blood cell will become crenated. Blood volume will increase causing the blood pressure to increase as well. ]]> 2021-02-14 04:02:34 UTC https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1200162923 https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1200167330 When your body takes in too much salt,  which contains sodium, your body holds extra water to "wash" the salt from your body. This may cause blood pressure to rise. The added water puts stress on your heart and blood vessels. A region of high water potential in our body will move to a lower water potential which is the salt, taking away the water in our body by osmosis. Thus, blood pressure will increase as water starts to leave our red blood cells, which then will start to shrink.]]> 2021-02-14 04:07:39 UTC https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1200167330 https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1201018429 The patient with hypertension have to limit their salt intake. This is because when too much salt enters one’s body, there will definitely have lower water potential in the body. The kidney in your body controls your blood pressure by taking out water from your bloodstream.However, if there is not sufficient water present in the body, the red blood cells will shrink due to the low water potential and be crenated. So in order not make our red blood cells be crenated, the water will travel from the higher water potential to the lower potential (a water potential gradient) causing more amount of water to circulate in the blood and prevent the red blood cells from shrinking and instead becomes bigger a bit in size.As containing salt will mean sodium in your blood stream which means that it will pull the water back in due to low water potential instead of removing some water out as usual. (More salt which means must have more water in your bloodstream) When there is too much salt and thus too much water in your bloodstream, there will be high blood pressure your body as increase water will cause increasing volume of blood in the bloodstream to be pumped through blood vessels and have to work harder than usual. When more blood and red blood cells flows through the blood vessels, there is more friction between them (red blood cells and the wall of blood vessel) causing the walls of blood vessels to grow thicker which leads to narrow vessels and thus increase in our blood pressure. Narrow vessels means lesser oxygens and nutrients get transported to the cells.]]> 2021-02-14 12:52:09 UTC https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1201018429 https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1201213589 The idea salt will increase your blood pressure has to do with osmotic pressure. Osmosis is the movement of a solvent (in this case water) across semi-permeable membranes (like cell walls), from areas of lower solute concentration (in this case salt) to areas of higher solute concentration. This naturally equalizes the solute concentration on both sides of the membrane. When we eat too much salt, our bloodstream has more sodium in it than the surrounding areas of our body. This causes the water in those areas to be pulled into our bloodstream. The increase in water within the arteries and veins causes an increase in the pressure within those arteries and veins. The salt itself also acts like an irritant within the arteries causing them to constrict. This too is thought to increase your blood pressure.]]> 2021-02-14 15:00:43 UTC https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1201213589 https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1202369658 A patient with high blood pressure must limit their salt intake. This is because patients with high blood pressure have a lower water potential and a higher salt concentration. When a patient eats too much salt, the patient’s body hold on to water in effort to dilute it. This extra water increases your blood volume, which means that the patient’s heart is pumping blood more vigorously as it is pushing more liquid through the patient’s blood vessels. When there is more strenuous pumping of the heart, it increases the pressure put on the blood vessels. Eventually ,this increased force on the blood vessels and damage the blood vessels, increasing the risk of stroke , heart attacks and heart failure]]> 2021-02-15 05:09:21 UTC https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1202369658 https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1202375818 too much salt can cause the blood to be very concentrated in salt, therefore the body would have to pump the areas with concentrated salts to the other areas of the body with lesser concentrations so that it is equally concentrated, thus the body has i higher blood pressure to pump the salts around our body.]]> 2021-02-15 05:13:17 UTC https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1202375818 https://padlet.com/msleeamanda/3A5CNYosmosisdiscussion/wish/1202421553 The patient with hypertension have to limit their salt intake.

This makes the red blood cells crenated thus the body would have to make more red blood cells to suffice for the lack of water the crenated red blood cells have and thus a higher pressure from the heart is need to pump the blood to the rest of the body as the red blood cells in the body increases. Water is needed to hydrate the red blood cells so that the cell will not shrivel up and be smaller which would decrease the amount of oxygen travelling through the body.
