1) All the living organims are compound by one or more cells . 2) The cell is the structural and functional basic unit of life. 3) All cells are originated from other cells.

Explanation: Cell theory describes the characteristics of living organisms and was proposed and refined by many scientists like Schwann and Schleiden. The first principle describes the constitution of living organisms, all of them, unicellular or multicellular are compund by cells. The second principle says that cell is the unit of life in fuctions as metabolism and structural as in tissues. The third principle says that cells can only be generated by division of preexisting cells.

Explanation:

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.
