PPT-Capillaries

and Exchange of Materials Learning Outcomes Capillaries allow exchange of substances with tissues Pressure filtration of fluids through capillary walls Similarity of tissue fluid and blood plasma with the exception of plasma proteins Tissue fluid supplies cells with glucose oxygen and other substances Carbon dioxide and other metabolic wastes diffuse out of the cells and into the tissue fluid to be excreted . Cardiovascular System. Simplest Circulatory System: The . Gastrovascular. Cavity. found in . animals that lack a true circulatory . system. can function in the distribution of materials throughout the body. The terminal end of an arteriole tapers toward the capillary junction to form a . single metarteriole. .. At the metarteriole-capillary junction, the distal most muscle cell forms the . . precapillary sphincter. March . 26-27. , . 2014. Pulse Points. Areas where can easily feel pulse. Also act as . pressure points. . Compressing these points will reduce downstream blood flow . useful when dealing with major wounds.. Anatomy and Physiology. On the white boards outline the process of fainting after an athlete performs exercise and then stops abruptly. (clue, vascular return) . Cause . During exercise – high Q (what is Q). Essential Knowledge: 2.A.3 Organisms must exchange matter with the environment to grow, reproduce, and maintain organization 2.D.2 Homeostatic mechanisms reflect both common ancestry and divergence due to adaptation in different environments. Anatomy and Physiology. On the white boards outline the process of fainting after an athlete performs exercise and then stops abruptly. (clue, vascular return) . Cause . During exercise – high Q (what is Q). -pumps and directs blood cells and substances carried in blood to all tissues of the body.. Cardiovascular . System. The CVS is composed of:. Heart-. . an organ whose function is to pump the blood.. Types of circulatory systems. Diffusion – oxygen and carbon dioxide, based on body shape and size. Gastrovascular. cavities . – distribution of substances throughout the body and in digestion.. Open circulatory system . The .
