Draw a schematic representation of transport and exchange of oxygen and Biology Diagrams Some general comments about gas exchange and diffusion will be made, followed by a description of how oxygen is carried in the blood. The binding of oxygen to hemoglobin will be discussed, including the oxygen saturation (or dissociation) curve and factors (allosteric effectors) which cause it to shift. Next, a discussion of the effects of carbon monoxide on oxygen binding will be presented
Oxygen transport within the human body occurs through both convection and diffusion. Within the pulmonary capillaries, one haemoglobin molecule binds up to four oxygen molecules in a cooperative manner. Global oxygen delivery, or oxygen dispatch, describes the total amount of oxygen delivered to the tissues each minute, and is a product of the
Introduction to the Respiratory System Biology Diagrams
The cardiovascular or circulatory system is designed to ensure the survival of all cells of the body at every moment and it does this by maintaining the immediate chemical environment of each cell in the body (i.e., the interstitial fluid) at a composition appropriate for that cell's normal function. The term "homeostasis" is used to denote the approximate constancy of the internal
Human respiratory system - Oxygen Transport, Lungs, Airways: Oxygen is poorly soluble in plasma, so that less than 2 percent of oxygen is transported dissolved in plasma. The vast majority of oxygen is bound to hemoglobin, a protein contained within red cells. Hemoglobin is composed of four iron-containing ring structures (hemes) chemically bonded to a large protein (globin).
The Circulatory System and Oxygen Transport Biology Diagrams
Carbon dioxide is exhaled and oxygen is inhaled through the respiratory system, which includes muscles to move air into and out of the lungs, passageways through which air moves, and microscopic gas exchange surfaces covered by capillaries. The circulatory system transports gases from the lungs to tissues throughout the body and vice versa.
