Because of this, carbohydrates are necessary in our diet because our body is unable to convert fatty acids to glucose. Proteins supply the blood with essential amino acid. The body breaks down amino chains to make proteins. Minerals are needed either in in trace or large amounts. Vitamins are other organic compounds the body cannot synthesize; Fatty acids are molecules that contain a hydrocarbon chain and ends with an acid group. Unsaturated fatty acids like omega- fatty acids are protective against cardiovascular disease. Essential fatty acids must be supplied by the diet; however saturated fatty acids and Tran’s fat contribute to heart disease.

Ovaries are female gonads that produce eggs and sex hormones (estrogen and progesterone). The oviducts (uterine tubes) are a tube that extends from the uterus to the ovaries that transports eggs to the uterus. It is the location of fertilization. Implantation is where the embryo embeds in the uterine lining. The uterus is a thick-walled, muscular organ located in the pelvis (female). It is about the size of a pear and lies above and is tipped over the urinary bladder. This is where the fetus develops, also known as the womb.
