The Capillary Bed The capillary bed is found in the superficial dermis and is an important part of the integumentary system. It is made up of a group of capillaries which are supplied with oxygenated blood via the arterioles and drained of deoxygenated blood via the venules of the circulatory system. The pulsating flow within the capillary bed is called vasomotion. The type of circulation through the capillaries is called microcirculation. Image 1 bellow shows the components of the capillary bed

SENSE- is the ability to perceive stimuli. SENSATION (PERCEPTION)- is the conscious awareness of stimuli received by sensory receptors. GENERAL SENSES- are those with receptors distributed over a large part of the body. SOMATIC SENSES- provides sensory information about the body and the environment. VISCERAL SENSES- are more specialized in structure and are localized to specific parts of the body such as pain and pressure. SPECIAL SENSES- are more specialized in structure such as smell

INTRODUCTION TO PHYSIOLOGY AND HOMEOSTATIS PHYSIOLOGY 1.1 Intro to Physiology Physiology: the study of the functions of living things‚ how the human body works Two approaches explain the events that occur in body -purpose of the body process - mechanism in which the process occurs Physiologists view the body as a machine whose mechanisms of action can explained in terms of cause and effect sequences of physical and chemical processes. Physiology is closely related to anatomy: the
Premium Homeostasis Cell Organism
Homeostasis maintains the body’s internal environment it allows organs and cells to function at their best. It keeps the body at steady state‚ this refers to the fact that conditions need to remain constant‚ if not then normal function would be disrupted. However there is a certain limit set ‚ this is due to the changing values ‚ rather they are maintained around an ideal value which is also known as the set point. The skin regulates most of the body temperature and uses a mechanism called negative
