Explain development of embryo |
| Answer» \tDuring fertilization, chromosomes of the ovum and the chromosomes of the sperm make up into pairs and the resulting cell is called zygote.\t Fertilization takes place in the oviduct or fallopian tube.\t The zygote which is diploid travels down the fallopian tube. As it moves it undergoes several mitotic divisions forming the embryonic stage called blastocyst.\t Blastocyst moves towards the wall of the uterus and finally gets attached and embedded in the wall of the uterus. This is called implantation.\t The growing embryo forms two membranes chorion and Amnion.\t Chorion establishes connection with the walls of the uterus and helps in the supply of nutrients to the embryo and removal of wastes from the embryo.\t Amnion forms a sac like structure around the embryo. The space between the amnion and embryo is filled with a fluid called amniofic fluid.\t Amnion and amniotic fluid give protection to the embryo against minor mechanical injury.\t Placenta is a tissue formed by the cells from the embryo and the mother. It is formed around 12 weeks of pregnancy.\t Placenta nourishes the growing embryo.\t A tough cord called umbilical cord is also formed by the embryo which is connected to the walls of the uterus through the placenta.\t From 3 months of pregnancy, the embryo is called foetus.\t Pregnancy lasts on an average 9 months or 280 days. This period is called gestation period. | |

Ingestion,digestion,absorption,assimilation,egestion Ingestion :taking of food in our mouth through handDigestion : the process of breaking down of complex food into simple food particle. Absorption : the process of absorption of digested food by the help of Villi in small intestine. Assimilation : after absorption digested food enter and goes to different cell like spread all over body and release energy in mitochondria in the cells. Egestion : the process of removing of waste materials through our body There are 5 type of nutrition |

??can any one explain structure of heart??? ??nobody |
|
Answer» Thanks akash raj @diti Heyy dear here is ur answer :The human heart has four chambers, the right atrium, the right ventricle, the left atrium and the left ventricle. The right and left sides are completely seperated by the septum, this is so that the oxgenated blood and deoxygenated blood are kept seprate and are not able to mix, allowing for maximum oxygenation. The left side carries oxygenated blood and the right side carries deoxygenated blood. There are four sets of valves, two sets of semi-lunar valves, one set between the right ventricle and the pulmonary artery and the other set between the left ventricle and the aorta. There are also two sets of atrioventricular (AV) valves, one set between the right atrium and the right ventricle, which is called the tricuspid valve, the other set of AV valves are between the left atrium and the left ventricle, which is called the bicuspid valve. The valves in the heart are required to prevent backflow of the blood. The ventricle walls are thicker than those of the atria because the ventricles have to pump blood out of the heart to different parts of the body so require more strength to do this, where as the atria only have to pump blood into the ventricles. The left ventricle wall is thicker than the right ventricle wall because the left ventricle has to pump blood to the whole body, where as the right ventricle only pumps blood to the lungs, which is a shorter distance. Heart is four chambers .It pumps blood and collect the impure blood |
