continue to move down the fallopian tube into the uterus. On or about the seventh day, the blastocyst develops chorionic villi, hairlike structures used to absorb nutrients for the growth of the embryo, which enable it to implant into the lining of the uterine wall. According to Biology of Reproduction, the chorionic villi in the placenta function as necessary structures in exchanges between the fetus and mother. Blastocyst The blastocyst will develop into two separate parts. The outer cells develop

The Human Heart versus the Artificial Heart As one of the most vital organs, the heart can viewed as the engine of the body. Without proper upkeep, like any engine, the heart will malfunction. Heart malfunctions only have negative results, such as heart failure and other fatal diseases. The heart is essentially a shell containing four cavities; two atriums and two ventricles. Each side of the heart contains one atrium and one ventricle and is separated in the middle by a wall known as the septum

paleoanthropologist, Donald Johanson and his co-worker Tom Gray found my fossil at Hadar, Ethiopia. From now on people could know that I existed once on this earth a long time ago.

Candi Smith-Wiggleswire 2-12-2009 Adaptation of Sensory Receptors Sensory receptors account for our ability to see, hear, taste, and smell, and to sense touch, pain, temperature, and body position. They also provide the unconscious ability of the body to detect changes in blood volume, blood pressure, and the levels of salts, gases, and nutrients in the blood. These specialized cells are exquisitely adapted for the detection of particular physical or chemical events outside the cell. They

Patterns of Evolution Humans are still subjected to the same pressures of natural selection as other organisms because we also compete for sources of food as our society becomes over populated while adapting to environmental concerns, such as global warming with radically different changes in climates, contaminated water sources, or other forms of pollution. Survival of the human race will require reproduction to avoid becoming extinct, thus ensuring the perpetuation of favorable traits in preceding
