How are arteries related to blood pressure?
Because arteries have to do with giving blood to body parts and blood pressure has to do with the amount of blood you have and the arteries have a huge part in that!!! Thank you arteries are the carriers of oygenated blood to the body . blood pressue is very high. the walls are made of elstic material which can either contract or dilate due to pressure changes. blood pressure levels can be influenced by exercise ie when muscles are in motion and temperature changes
How do tides affect coastlines?
high waves thrashing and large sea levels.
What instrument measures cold fronts?
A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems, and frontal boundaries. http://en.wikipedia.org/wiki/Barometer#Applications
Why do you fast before a blood test?
So the food doesn't affect your blood in any way (it can raise or lower your normal blood sugar levels).
What are the diseases can affect the endocrine system?
Diabetes and thyroid disease effects the endocrine system significantly. Each of these diseases have an effect on hormone levels, which is an indication of endocrine system issues.
How does electrolytes affect osmosis?
Electrolytes play a role in osmosis by influencing the movement of water across a semipermeable membrane. When electrolytes are present in a solution, they can create an osmotic pressure that affects the direction and rate of water movement. This can lead to changes in the osmotic balance and cell hydration levels.
How does potassium affect osmotic pressure?
Potassium ions contribute to osmotic pressure by affecting the concentration of solutes in a solution. When potassium ions are present in a solution, they increase the overall solute concentration, which in turn increases the osmotic pressure of the solution. This means that higher levels of potassium can lead to an increase in osmotic pressure.
Does osmotic pressure affect seed germination?
Your question is extremely imprecise, but high salt levels in a soil will stop the seed absorbing water which it must do to germinate. Even if it did germinate, the roots would not be able to function properly.
Why would osmotic pressure be low in someone who is starving?
histamines.
What is the relation of the donnan effect to osmotic pressure on capillary and on pH?
The Donnan effect refers to the uneven distribution of ions across a semipermeable membrane, affecting osmotic pressure by causing water to move across the membrane. In capillaries, this can impact fluid balance between blood and tissues. The Donnan effect can also influence pH by affecting the distribution of charged molecules, such as ions or proteins, leading to changes in the local pH levels.
What would be the effect of low blood protein levels on the colloidal pressure?
If blood protein levels become low, then there will be a decrease in colloidal osmotic pressure. This in turn can cause side effects in the body like edema and muscle degeneration.
How does low blood pressure at high altitude affect the body's ability to adapt to changes in oxygen levels?
Low blood pressure at high altitude can affect the body's ability to adapt to changes in oxygen levels by reducing the amount of oxygen-rich blood reaching the body's tissues. This can lead to symptoms like dizziness, fatigue, and shortness of breath, making it harder for the body to adjust to the lower oxygen levels at high altitudes.
What is the relationship between hydrostatic pressure and osmotic pressure in capillaries and how do they influence fluid movement within the circulatory system?
Hydrostatic pressure is the force exerted by fluid within capillaries, pushing fluid out. Osmotic pressure is the force caused by the concentration of solutes, pulling fluid in. These pressures work together to regulate fluid movement in the circulatory system. Hydrostatic pressure pushes fluid out of capillaries, while osmotic pressure pulls fluid back in. This balance helps maintain proper fluid levels in the body and ensures nutrients and waste are exchanged efficiently.
How hypoalbuminemia cause leuconychia?
Hypoalbuminemia, characterized by low levels of albumin in the blood, can lead to leuconychia, which is the whitening of the nails. This condition occurs because albumin plays a crucial role in maintaining osmotic pressure and fluid balance in tissues. When albumin levels are low, it can result in edema and changes in the nail matrix, leading to the appearance of white spots or bands on the nails. Additionally, hypoalbuminemia may indicate underlying systemic issues that can affect nail health.
Why is pressure measured in mercury?
Pressure is measured in mercury because mercury is a dense liquid that is sensitive to changes in pressure. When pressure is applied, the height of the mercury in a column changes, allowing for accurate measurement of pressure levels.
How does pressure affect tides?
Pressure affects tides primarily through its influence on sea level and water density. Changes in atmospheric pressure can lead to variations in sea level; for instance, lower atmospheric pressure can cause water levels to rise, while higher pressure can result in lower sea levels. However, these effects are generally minor compared to the gravitational forces exerted by the moon and the sun, which are the primary drivers of tidal movements. Overall, while pressure can have some impact, it is not the main factor in tidal changes.
Starvation causes the plasma protein levels in the blood plasme to fall how would that affect the formation of tissue fluid in the tissue spaces?
Starvation causes the plasma protein levels to decrease, and when there is less plasma protein in the blood, you get lower Po (Osmotic Pressure). Lower osmotic pressure means less pull (of tissue fluid) so this causes generalized edema.so basically, less plasma proteins -> decreased Po -> less pull -> reduced venous clearance --> fluid build up in tissue
