The 4 main macromolecules in cells made largely from C, O, H, and N are Carbohydrates, Lipids, Proteins, and Nucleic Acids. For each of these 4 macromolecules, I would like you to know: 1. What the monomer (basic building block) is 2. What types of polymers result 3.
Inferior vena cava. The inferior vena cava is also referred to as the posterior vena cava. The inferior vena cava is a large vein that carries de-oxygenated blood from the lower body to the heart. De-oxygenated blood means most of the oxygen has been removed by tissues, and therefore the blood is darker.he right atrium is located on the lower right back side of the heart. The inferior vena cava runs posterior, or behind, the abdominal cavity. This vein also runs alongside the right vertebral column of the spine. The inferior vena cava is the result of two major leg veins coming together.
The inferior vena cava is one of the two main veins bringing de-oxygenated blood from the body to the heart. Veins from the legs and lower torso feed into the inferior vena cava, which empties into the right atrium of the heart.
