2) What happens when veins get cut ?
Answers
Answer:
1. White adipose tissue (WAT) or white fat is one of the two types of adipose tissue found in mammals. The other kind is brown adipose tissue. In healthy, non-overweight humans, white adipose tissue composes as much as 20% of the body weight in men and 25% in women.
explanation . In healthy, non-overweight humans, white adipose tissue composes as much as 20% of the body weight in men and 25% in women. Its cells contain a single large fat droplet, which forces the nucleus to be squeezed into a thin rim at the periphery. They have receptors for insulin, sex hormones, norepinephrine, and glucocorticoids.
White adipose tissue is used for energy storage. Upon release of insulin from the pancreas, white adipose cells' insulin receptors cause a dephosphorylation cascade that lead to the inactivation of hormone-sensitive lipase. It was previously thought that upon release of glucagon from the pancreas, glucagon receptors cause a phosphorylation cascade that activates hormone-sensitive lipase, causing the breakdown of the stored fat to fatty acids, which are exported into the blood and bound to albumin, and glycerol, which is exported into the blood freely. There is actually no evidence at present that glucagon has any effect on lipolysis in white adipose tissue.[1] Glucagon is now thought to act exclusively on the liver to trigger glycogenolysis and gluconeogenesis.[2] The trigger for this process in white adipose tissue is instead now thought to be adrenocorticotropic hormone (ACTH),[3][4] adrenaline[5] and noradrenaline[citation needed]. Fatty acids are taken up by muscle and cardiac tissue as a fuel source, and glycerol is taken up by the liver for gluconeogenesis.
2.answer-If a vein is bleeding, the sight of it will still be disturbing, but it will not be pulsatile and it will be low pressure. Hopefully, you'll put pressure on it either way and it will stop bleeding. The arteries supply freshly oxygenated blood, the veins bring back the used blood back to the lungs for recharge.
