Haemoglobin is something that is found within red blood cells known as protein molecules which transports oxygen to the cells around the body from the lungs. This molecule also transports carbon dioxide to the lungs from the cells around the body. The protein molecule consists of globulin chains with a total of four molecules which are all linked. Generally, the haemoglobin within adults consists of two alpha-globulin chains and two beta-globulin chains, however in fetuses, beta chains do not remain common and the molecule of haemoglobin consists of two alpha chains as well as two gamma chains, the same applies for infants. The transition stage between infant and adult cause’s beta chains to be present rather than gamma chains.

The erythropoietin receptor is found within the cardiovascular system in a variety of areas which is distributed which includes endothelial cells, cardiomyocytes, and smooth muscle cells. The function of erythropoietin is to control/maintain the volume of the formation of red blood cells. The erythropoietin has an effect on the respiratory system due to the function of maintaining red blood cell production, if more red blood cells are being produced this would result in the respiratory system having to obtain a higher volume of oxygen for red blood cells to use.
Athletes or army students are examples of people who require the function of erythropoietin more than the average person as physical processes they carry out require their cells to function with the necessary volume of oxygen. Taking their training routines to a high altitude would assist them as the production of red blood cells would increase providing a higher capacity of oxygen. A training routine in the army Is to travel up mountains to high altitudes repeatedly which enables them to produce more red blood

This involves keeping up to date with information on the legal issues that affect safe working practices.

Learners will use their knowledge of relevant human resources management theory and link it with current human resource management practices in organisations.

Many organisations say that their employees are their most valuable resource because of their skills, knowledge and attitudes. As labour is both an expensive and valuable resource, it is important to ensure it is planned and that the best value is obtained from employees contributions. Human resource managers have to plan their human resource requirements against a background of internal and external factors which are dynamic and constantly changing.
