chemicals from the blood to form urine. Ureters The ureters are a pair of tubes that carry urine from the kidneys to the urinary bladder. The ureters are about 10 to 12 inches long and run on the left and right sides of the body parallel to the vertebral column. Gravity and peristalsis of smooth muscle tissue in the walls of the ureters move urine toward the urinary bladder. The ends of the ureters extend slightly into the urinary bladder and are sealed at the point of entry to the bladder by the ureterovesical

Similarities of physiology and behaviour due to homology - share common ancestor with that trait or analogy - not due to common ancestor but common due to convergent evoution. Improvement suggestions: the behavioural homology of crocodiles and birds may be flawed. Also the analogy between fish and mammals could be wrong as the post-anal tail of quadrupedal mammals and fish is a common trait.

Hox Genes | November 15 2010 | | Comparative Vertebrate Anatomy | Homeotic complex (Hox) genes are defined as a group of related genes that specify the anterior-posterior axis and segment identity of metazoan organisms during early embryonic development. These are situated very close to one another on the chromosome in groups of clusters. The orders of these genes located on the chromosomes are the same as the expression of the genes in the development of an embryo‚ whereas the first

Homo Floresiensis: A Creature of Controversy Since its discovery in 2004‚ Homo floresiensis has sparked tremendous controversy among archaeologists across the world (Aiello‚ 2010:169). Found on the island of Flores (hence the name)‚ located in the midst of Indonesia‚ the fossil remains present a dilemma that is often compared to that surrounding the Neanderthals (Liberman‚ 2009:41). Simply put‚ the discovery of Homo floresiensis challenges the prevailing record of human history. Homo floresiensis

The Human Skeletal System Introduction The human skeletal system is comprised of both fused and individual bones; supported and supplemented by ligaments‚ tendons‚ muscles and cartilage. The skeletons purpose is to protect and support the delicate internal organs and provide a framework that allows the body to stand upright and move. It also produces blood cells and stores minerals that our body needs to function effectively. The skeletal system is a very important part of the human body. Without
