Gas exchange circulatory system
WebGas Exchange • Partial pressure is an important measurement when discussing gases – total pressure exerted by a gas mixture x % of a particular gas in that mixture • (at sea level, the pressure of the atmosphere is 760mm Hg---O 2 represents 21% of the mixture, so. . . 760 x .21 = 160mmHg) • O 2 has a pp of 160mm Hg at sea level ... WebGas exchange by direct diffusion across surface membranes is efficient for organisms less than 1 mm in diameter. In simple organisms, such as cnidarians and flatworms, every cell in the body is close to the external environment. Their cells are kept moist so that gases diffuse quickly via direct diffusion.
