Improvements 6 The effect of exercise on the heart rate and breathing rate Introduction Aim: Finding out how exercise affects the heart rate and breathing rate. Hypothesis: Exercise exists in different forms and has many benefits; it improves the oxygen-carrying capacity of the blood‚ development of bones‚ strengthens muscles and the lungs capacity plus it can make you feel good. There are different exercises and intensities for different benefits. Lower intensity exercises are not designed to work

2. Compare the development of lymphocytes with other formed elements. B lymphocytes develop in red bone marrow‚ T lymphocytes develop in red bone marrow and mature in the thymus; the other formed elements develop in red bone marrow 3. What is erythropoiesis? Which factors speed up and slow down erythropoiesis? Erythropoiesis is the process by which red blood cells (erythrocytes) are produced. If you lose a lot of blood‚ erythropoiesis will speed up; anemia can cause erythropoiesis to slow down

“ Ageing is a continuous‚ complex‚ and dynamic process that begins with birth and ends with death. And unless we die in our early years‚ each of us will grow old and experience the effects of the ageing process”. (Pirkl‚ 2009). The ageing process and why changes have taken place in the last fifty years. This report discusses the ageing process and why changes have taken place in the last fifty years. The ageing process is a change in an organism overtime and can be referred to as a multidimensional
