that is pumped by the heart and circulated through the body via a system of arteries and veins. It is an essential component of the body and without it we would not be able to survive. This paper discusses the anatomy and physiology of blood in a brief review. Anatomy and Physiology of Blood The blood is made up of four main components. These are plasma‚ red blood cells‚ white blood cells and platelets. The blood is circulated throughout the body by one of two types of vessels; arteries or

LABORATORY REPORT RENAL PHYSIOLOGY INTRODUCTION: The kidneys‚ which maintain the purity and constancy of our internal fluids‚ are perfect examples of homeostatic organs. They regulate the chemical content the pH and osmotic pressure of the blood. Kidneys filter gallons of fluid from the bloodstream. They then process this filtrate‚ allowing wastes and excess ions to leave the body in urine while returning needed substances to the blood in just the right proportions. Factors that affect urine

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

ANATOMY & PHYSIOLOGY of the EYE Even though the eye is small‚ only about 1 inch in diameter‚ it serves a very important function -- the sense of sight. Vision is by far the most used of the five senses and is one of the primary means that we use to gather information from our surroundings. More than 75% of the information we receive about the world around us consists of visual information. The eye is often compared to a camera. Each gathers light and then transforms that light into a "picture
