Question

Choose the odd one.

Ovary, fallopian tube, ureter, uterus.

Answer 1

Explanation for the odd one:

Ureter:

1. A ureter is a part of the human excretory system.
2. Urine travel from the kidney to the bladder through the ureter.
3. These are thin tubes about 8 to 10 inches long.

Explanation for the remaining ones:

Ovary:

1. It is a female reproductive structure.
2. It is oval in shape and produces ova.
3. It also produces estrogen and progesterone.

Fallopian tube:

1. It is a part of female reproductive system. This tube is responsible to pick up the ovum released from the ovary with fimbriae.
2. Eggs pass from the ovary through fallopian tube to the uterus.
3. After the release, egg moves into the fallopian tube and stays there for about 24 hours, where it can get fertilized.

Uterus:

1. It is a somewhat triangular and hollow muscular organ. It is a part of female reproductive system.
2. It is present between in bladder and rectum in pelvic region of female body.
3. The uterus is the organ that provides the site for the implantation of the fertilized egg.

Final answer: Hence, the ureter is the odd one because the ovary, fallopian tube and uterus are the reproductive parts (female). The ureter is the excretory part.
