Thisintricate system allows the fetus to receive oxygenated blood and nutrients from the placenta. With the umbilical cord clamping after birth, the systemic vascular resistance increases, helping the blood flow towards the lungs. From the IVC, blood travels through the right atrium of the heart to be directed across a shunt into the left atrium. The skeletal system is comprised of bones and cartilage. Geneticists are busy analysing all aspects of the human genome, including its previously overlooked SINES. It is the system that helps in the movement and locomotion of the body.
