During the third week of human embryonic development, the following layers form and will eventually differentiate and form specific adult tissues (some examples are shown in the cartoon and below). This transition occurs around ten weeks of gestation. Pigs have the same muscles as humans in almost every case; however, since pigs are quadrupedal and humans are bipedal, there are small variations between size and location of some muscles.

Current developmental biology shows that animals follow similar developmental programs, but do not go through a "species change" during development. In post-ductal coarctation of the aorta, deoxygenated blood travels from the right atrium to the right ventricle and then through the pulmonary artery. Current developmental biology shows that this is not the source of primordial germ cells or follicle components, but is a cuboidal epithelium overlying a dense connective tissue layer (tunica albuginea). Epub 2020 Oct 16. What is Sarcomere? Although the kidney is basically similar in all vertebrates, its structure and function vary somewhat among vertebrate taxa. [1]Another area of concern is when certain shunts fail to close after birth; the baby can be born with congenital heart defects that present with varying signs and symptoms; this is discussed further below. In the tetralogy of Fallot, a boot-shaped heart due to right ventricular hypertrophy may be present on a chest X-ray.

Near-infrared spectroscopy (NIRS) is a tool to measure the oxygenation of fetal tissues noninvasively, and physicians can then calculate blood flow and oxygen delivery. The late fetal/newborn/adult stages reflect the emergence of species-specific body plans as a result of differential growth. It is characterized by pulmonary stenosis, a VSD, an overriding aorta, and hypertrophy of the right ventricle. Many studies have investigated similarities and differences between animals and humans in the lumbar and thoracic vertebrae.

Blood then enters the systemic circulation, and the deoxygenated blood, with an estimated oxygen saturation of 40%, is recycled back to the placenta via the umbilical arteries to be oxygenated again by the mother.[2]. Here the clavicle bone is only present in humans. They both have the overlap where the duodenum meets the jejunum in the small intestine.
