(lldbomacp) a turn or sharp curve in a cordlike structure.
capillary loops  minute endothelial tubes that carry blood in the papillae of the skin.
closed loop  a type of feedback in which the input to one or more of the subsystems is affected by its own output.
loop of Henle , Henle's loop the long U-shaped part of the renal tubule, extending through the medulla from the end of the proximal convoluted tubule. It begins with a descending limb (comprising the proximal straight tubule and the thin tubule ), followed by the ascending limb (the distal straight tubule ), and ending at the distal convoluted tubule.
open loop  a system in which an input alters the output, but the output has no effect on the input.

2. A wire (of platinum or other materials) fixed into a handle at one end and bent into a circle at the other, rendered sterile by heat, and used to transfer microorganisms.

loop

A circular bend or fold in a vessel or a bundle of nerve or muscle fibres.
Archambault's loop See Meyer's loop.
Axenfeld's intrascleral nerve loop An anomalous loop of the long ciliary nerve, often accompanied by the anterior ciliary artery, which has pierced the sclera a few millimetres behind the limbus and then re-enters the sclera and supplies the ciliary body. It is usually pigmented giving rise to a 1-2 mm black dot on the sclera. It appears only in a small percentage of individuals (10-15%). Treatment is not necessary. Syn. Axenfeld's pigmented nerve loop.
Meyer's loop A bundle of inferior nerve fibres that originate from the lateral portion of the lateral geniculate body, extend forward around the anterior tip of the temporal horn of the lateral ventricle and then swing backward toward the occipital lobe. A lesion in this loop may cause a superior homonymous quadrantanopia. Syn. Archambault's loop. See optic radiations.

intestinal loop
in most species the small intestine is arranged in a series of indefinite open loops. In ducks and geese the loops are closed, finite structures, five to eight in number, and are located more or less in fixed positions. The supraduodenal loop is one of them.
open loop
a system in which an input alters the output, but the output has no effect on the input.

Patient discussion about loop

Q. Blood in stools before and after polyp removel, Avms of the deodenel loop, inside hems, and 3cin tubuo adenoma Hi, On Nov of 06 I had a colonoscopy done and they didnt find any thing that could be mking me bleed and go to the rest room often. Then in Nov of 07 did a EDg and found I have AVMs of the deodenel loop.She Burned them and I didnt have any more bleeding till June of thei yr.On 6/6/08 i had another EDg done she burned more AVMs and on Mon I started bleeding again. This time she did a colonoscopy and found I had inside hems and a 3cin tubuolvillous adenoma inflamed.She cut, burned, and took it out in peices.She saye she will go back in Nov of this yr and look again. Two weeks after I had this done I had started to bleed again and had bad such bad pain in my hip I had to hold on to walk. that same day i started to bleed again. I bled out big clots and a bowl full of blood! A few days later the pain went away but was still bleeding ever time I had bowl movement!I can bleed up to 4 days at a times sometimes. I have been taking HC supp. and it seems to have stoped the bleeding and pain!

A. It is normal that after a polyp removal you will continue bleeding some more. However, if you feel like there is a lot of bleeding, and/or you are not feeling well, you should see a doctor as soon as possible to stop the bleeding or look for the source of bleeding.
