Anaerobic respiration takes place in muscles of human beings. this happens when we do a more amount of physical work. and sometimes sufficient amount of oxygen is unable to reach the muscles hence anaerobic respiration occurs in muscles and lactic acid is formed
The body increases the oxygen to the muscles by increasing the respiratory rate (breathing faster). Along with more rapid breathing, the body also dilates the blood vessels and increases the heart rate to speed the delivery of the oxygenated blood to the muscles.
Explanation: Resistance exercise can stimulate and activate bone cells to strengthen even build more bone mass. More technical hormones play a role too, but for simplicity strength training can slow bone loss or even rebuild bones.
