Images: [3] Every human body has billions of microscopic units called cells. Cells carry out numerous of chemical reactions and processes that make up the essence of life. The structure of cells varies in size and shape and has different functions. There are four main features

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

Fluid‚ Electrolyte‚ and pH Balance 1. The maintenance of normal volume and composition of extracellular and intracellular fluids is vital to life. List and briefly describe the kinds of homeostasis involved. In males and females‚ intracellular fluid has a greater proportion of total body water than does extracellular fluid. Give-and-take between the ICF and the ECF happens across plasma membranes by osmosis‚ diffusion‚ and carrier-mediated transport. The kinds of homeostasis involved are fluid

THE ORGANISATION OF THE HUMAN BODY By Rachel Bull CELLS The organelles of cells and their function • Cell (or plasma) membrane - The plasma membrane acts as a boundary and controls what substances can enter and exit the cell. • Cytoplasm - This semi-fluid substance found inside the boundary of the cell and outside the nucleus cushions and protects the internal organelles‚ this is also where the majority of the chemical reactions happen. • Nucleus - The nucleus is the double-membraned central
