In what stage of mitosis is this cell going through?

It has four stages,

1- Prophase: The chromosomes are condensed into the X-shaped structures that can be easily seen under a microscope.  

2- Metaphase: The chromosomes come end-to-end at the center (equator) of the cell.

3- Anaphase: In this Phase, The sister chromatids are pulled apart by the mitotic spindle to the opposite poles. One spindle fiber pull a chromosome to one pole and other spindle fiber to the other pole.

4- Telophase: At each pole of the cell a full set of chromosomes gather together.

As we can see that the chromosomes are densed in the middle so it shows that the cell is dividing by the mitotic division and it is under the mitotic phase

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
