    Leonardo mistakenly depicted the cotyledons in the vascular walls of the human uterus that he had previously found in a cow uterus. [3] The other study, measuring 30.3×22 cm, shows female external genitalia , the supposed arrangement of abdominal muscles on the top right and fetus from different angles.

  3. Uterus - Wikipedia

    en.wikipedia.org/wiki/Uterus

    The uterus (from Latin uterus, pl.: uteri or uteruses) or womb (/ w uː m /) is the organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic and fetal development of one or more fertilized eggs until birth. [1]

  4. Female reproductive system - Wikipedia

    en.wikipedia.org/wiki/Female_reproductive_system

    The uterus or womb is the major female reproductive organ. The uterus provides mechanical protection, nutritional support, and waste removal for the developing embryo (weeks 1 to 8) and fetus (from week 9 until the delivery). In addition, contractions in the muscular wall of the uterus are important in pushing out the fetus at the time of birth.

    Hormones produced by the ovaries prepare the uterus to receive the ovum. The lining of the uterus, called the endometrium, and unfertilized ova are shed each cycle through the process of menstruation. If the ova is fertilized by sperm, it attaches to the endometrium and the fetus develops. [3]

  8. Fetus - Wikipedia

    en.wikipedia.org/wiki/Fetus

    A human fetus, attached to placenta, at three months gestational age. In humans, the fetal stage starts nine weeks after fertilization. [7] At this time the fetus is typically about 30 millimetres (1 + 1 ⁄ 4 in) in length from crown to rump, and weighs about 8 grams. [7] The head makes up nearly half of the size of the fetus. [8]

    The second stage is the pushing stage. The third stage involves the delivery of the placenta. And the last stage is the contraction of the uterus. [22] Once the fetus is sufficiently developed, chemical signals begin the process of birth, which begins with the fetus being pushed out of the birthing canal.
