Written summary of the structural of the heart
Deoxygenated blood enters the vena cava which then passes through the right atrium and then the triscupid valve into the right ventricle and then goes to the semi lunar valve and pulmonary artery to get oxygenated. After which, blood returns into the heart through pulmonary vein into the left ventricle and then leaves to the body through the semi lunar aorta

where does auxin cause elongation?
Only the region behind the tip of a shoot is able to contribute to growth by cell division and cell elongation. This part of a shoot is called the meristem. When light shines on the shoot predominantly from one side though, the auxin produced in the tip concentrates on the shaded side, making the cells on that side elongate and grow faster than the cells on the sunny side
