Because your uterus prepares to carry a baby every month and when you are not pregnant it has to get rid of the sack and all of the preparations that it made and do it all over again next month

Well, for one thing, it's your body's way of preparing for pregnancy. Once you get your period, it means that you are physically able to become pregnant and have a baby – although you don't necessarily feel ready!

Periods happen as a result of hormones released from a gland at the base of your brain called the pituitary gland. These hormones cause an egg to be released. At the same time, the lining of your uterus (or womb) is becoming thicker – like a soft and spongy bed, ready for the egg.

beks73 [17]

Answer: An extra cytoplasm enhance survival of a developing oocyte in such a way because cytoplasm serves as a reservoir of lipids, polysaccharide and lipids for the developing embryo.The more the cytoplasm content, more will be the nutrients for the developing embryo. The cytoplasm forms the yolk and provides nourishment to the developing embryo. As we know that the developing embryo requires more nutrition and the main source of nutrition is cytoplasm because the sperm has no reservoir of its own to provide nutrition to embryo.

Feliz [49]

The digestive, circulatory, respiratory and excretory systems interact in supplying matter and energy to body cells and in removing waste. A minor malfunction in one of the systems could lead to major malfunctions in others. It may eventually lead to cell damage or death.

All the cells in the body need oxygen( respiratory system) to maintain functioning--getting energy from food (digestive system) ingested and removing the waste (excretory system). Also, the respiratory system and excretory systems remove waste products such as carbon dioxide and urine and sweat. If it fails, the body will lose homeostasis.

Methods developed to improve efficiency and effectiveness of one system might help other systems preserve or improve functioning. If one system is compromised it may be assisted with or replaced by developed methods preventing it from accompanying damage to other systems.
