Answer:
Under anaerobic condition pyruvate is converted into lactate.
Explanation:
Human muscles use both anaerobic and aerobic respiration for the production of ATP. During the starting of intense activity, the oxygen supply is not enough to provide instant energy to the muscle, therefore, muscles use anaerobic respiration to generate ATP.
During anaerobic respiration, muscle do not use oxygen to burn glucose. During anaerobic respiration in muscles, the glucose is converted into pyruvate and then this pyruvate gets convert into lactate and this process is called lactic acid fermentation. In this process, 2 ATP are produced.

Easy:
The four chambers of the heart are the right and left atria, and the right and left ventricles. The main veins connected the heart are the superior and inferior vena cava, the main artery is the Aorta.
The first chamber, (the right atruim) recieves deoxygenated blood and forces it into the right ventricles which forces the blood into the lungs for oxygenation. Then the blood reenters the heart in the left atrium, which forces the blood into the left ventricle and then out the Aorta to the rest of the body.
sorry, but this question needed kind of a long answer to be answered correctly.
