antidiuretic hormone
If babies were unable to secrete renin, they would likely experience difficulties in regulating blood pressure and maintaining fluid balance. Renin plays a crucial role in the renin-angiotensin-aldosterone system, which helps control blood volume and systemic vascular resistance. Without adequate renin, infants could develop hypotension (low blood pressure), electrolyte imbalances, and potentially face challenges related to growth and development due to inadequate blood flow to organs. This condition would require medical intervention to manage the resulting complications.
since there were no enough water and salts reabsored, there woulnd't be enough blood volume, and blood pressure will be decreased.
If water was not reabsorb blood volume and blood pressure would drop. A person could not live under such circumstances.
An increase in blood pressure, blood volume, or permeability of the filtration barrier would increase net filtration pressure. On the other hand, a decrease in blood pressure, blood volume, or an increase in plasma protein concentration would decrease net filtration pressure.
something maybe blocking it like...your finger,rock,cell.
The average total blood volume of a horse is around 8% of its body weight. For example, a 1,000-pound horse would have an average total blood volume of around 80 pounds or 36 kilograms.
The average blood volume for a laboratory mouse is ~6-8% of total body weight. So a mouse of 20g = 1.2-1.6mL. Note: you will not be able to collect this much blood as this is the total blood volume. The total peripheral blood would be ~ 60-70% of the total blood volume.
Red blood cells in 10% salt solution
5.8g of sodium chloride would need to be added to the blood to bring the sodium ion concentration up to 0.140m with no change in blood volume. This is also known as the Ionic strength.
To measure the volume of any liquid, you use a graduated cylinder. (I'm a bit afraid as to why you would want to know that)
Blood and blood cells contain certain amounts of various ions, meaning that distilled water would be highly hypotonic in comparison. The osmotic pressure would cause the water to enter red blood cells, causing them to swell and burst.
Perhaps your systemic blood supply has decreased because more blood is acting to bring more oxygen/nutrients to where you've been wounded (i.e., your stomach). What method was used to measure your blood volume?
