To examine the effect of stroke volume on blood flow. _____________________________________________________________ The physiology of human blood circulation can be divided into two distinct but remarkably harmonized processes: (1) the pumping of blood by the heart‚ and (2) the transport of blood to all body tissues via the vasculature‚ or blood vessels. Blood supplies all

The Endocrine System Controls many body functions ~exerts control by releasing special chemical substances into the blood called hormones ~Hormones affect other endocrine glands or body systems Derives its name from the fact that various glands release hormones directly into the blood‚ which in turn transports the hormones to target tissues via ducts. Exocrine glands-transport their hormones to target tissues via ducts. Endocrine glands- secrete hormones into the bloodstream The Endocrine

HUMAN ANATOMY AND PHYSIOLOGY AN INTRODUCTION TO RESPIRATION In this essay we will consider a few major aspects of respiration. We shall first consider the interesting history of the study of respiration before moving on to our modern understanding of respiration. We will look at the structure and function of the respiratory system including the upper and lower respiratory tracts with a note on the control system. Secondly we will consider the physiology of respiration. Thirdly we will discuss some

Baker’s Cyst Anatomy And Physiology To better understand a Baker’s cyst‚ it helps to understand the anatomy of the knee joint. A cyst is a lined sac that contains fluid. Cysts that form around joints are due to a bulging of the joint capsule. A Baker’s cyst develops from the knee joint capsule. It protrudes into the tissues in the back of the knee. Four bones come together at the knee joint: * Patella/Kneecap - The patella is a small‚ flat‚ round bone that articulates with the femur in
