Iron retention in blood?
Excessive iron retention in the blood is a condition called hemochromatosis. The normal gain and loss of iron in a body is 1 milligram.
Low iron is most often simply due to low intake in the diet. Other than this, it may be low due to excessive iron loss, which can in turn be caused by blood loss e.g. due to menstruation. Being "low on blood", i.e. a low total blood volume can have entirely different causes. On the one hand, this can also be due to excessive blood loss, though this would require a large wound. On the…
1. constrict arterioles thus increase blood pressure, 2. stimulate ADH secretion from the anterior pituitary which increases water retention by the kidneys and also increases blood pressure, and 3. stimulate aldosterone secretion from the adrenal cortex which increases sodium retention in the kidneys leading to more water retention by the kidneys and helping to increase blood pressure too.
Very simply the blood contains iron, the iron is used to carry oxygen in the blood stream, oxidised iron is in effect rust. The blood turns red due to this. When the oxygen is removed from te blood stream the iron is no longer oxidised thus the blood turns blue, hence the blue blood returning to the heart.
There are several causes of water retention. Medical conditions which can cause it include heart or kidney problems. If the heart does not have enough pumping force, the kidneys will not be able to extract enough water from the blood so it will collect in the tissues. Another type of water retention can occur in women due to premenstrual hormonal changes. This water retention mostly affects the tummy before a woman's period. In pregnancy, water…
yes it can if you have healthy low blood pressure it can become extra low after donation of blood, and that can cause inproper blood transport to the organs including kidneys, this again after turn gives water retention as e.g. sodium clerance is reduced by a sleapy kidney, until the condition might normalize, evt via reduced sodium intake.
Iron is attracted by a magnetic force. Rust, a combination of iron and oxygen, is not attracted by a magnetic force. The iron in your body is essentially rust . . . that's why blood is red in color. Since the iron in your blood is not even partly pure iron, there is no magnetic attraction to it by any magnet.
