1) Superior Vena Cava: It returns de oxygenated blood from head and arms to heart.

2) Pulmonary Veins: Carries oxygenated blood from lungs to heart.

3) Right atrium: Receives de-oxygenated blood

4) Tricuspid valve: Prevents back flow of blood to the right atrium.

5) Right ventricle: Pumps blood to lungs via pulmonary artery

6) Inferior vena cava: Returns de-oxygenated blood from lower limbs and organs to the heart

7) The cardiac muscle functions with the help of its cardiac cells. These cells are responsible for the contraction of this muscle and sending blood to the atria and ventricles. That in turn, reaches the blood vessels of the circulatory system.

8) Left ventricle: Pumps blood to all parts of the body except lungs via aorta.

9) Bicuspid valve (Mitral valve): Prevents back flow of blood to the left atrium.

10) Semi-lunar valve (Pulmonary valve): Prevent back flow of blood

11) Pulmonary vein: Carries oxygenated blood to the heart from the lungs.

12) Pulmonary artery: Carries de-oxygenated blood from the heart to the lungs.

13) Aorta: The biggest artery in the whole body. Carries oxygenated blood to rest of the body.

All foods contain more nutrients in the raw state. On the other hand, the differences are not very great: ranging from approximately 10-25% in the case of most vitamins, while the difference is almost zero with respect to minerals.

Hello!!! There's a variety show which is called Exploration Of The Human Body. It's pretty cool, but there are quite a number of episodes. So, I'll post the link for it here (: But, it's in Korean, so you need to read the subtitles. There are several people who uploaded it, but the quality is not excellent, but it's not that horrible that you can't see a thing. I'll put the link of several people who uploaded because some of the episodes were taken down! I'm sorry but I'm going to post the link as the uploader's main youtube page so you may have to do a little searching! I'm just going to post episode 2 only... Enjoy~
