Question

Differences between the water medium and the air medium with respect to gas exchange What is partial pressure and how it is calculated The importance of partial pressure of oxygen in the atmospheric area and how may affect the diffusion of oxygen at the levels of the lungs Hormones secreted by the adrenal gland. Hormones produced by the hypothalamus/anterior and posterior pituitary gland and their function Understand the feedback mechanisms operating with respect to hormone production, and what may happen if such feedback mechanism is not functional Be able to differentiate between differ ways of heat transfer between an organism and its environment Understand the Fick equation/law of diffusion (parameters in the equation; and their importance in affecting the diffusion of gases) law of diffusion applies to all gas exchange systems the rate of diffusion D-the non coefficient depends on the diffusing substance the medium, and the temperature cross-sectional area where diffusion occurs. P1 and P2-partial pressures of the gas at two ions L-the path length between the locations Q=DA P1-p2/L Understand the equations describing the flow and resistance to the flow as the blood travels through the vasculature (parameters in the equations, and their importance in affecting the flow and resistance) Mechanisms used in the transport of gases (O2 and CO2) in the blood Chemical reactions involved in the transport of oxygen and carbon dioxide within blood

Explanation / Answer

SOLUTION:

Difference between the water medium and the air medium with respect to gas exchange

Air medium and Water medium are used as respiratory medium for gas exchange.

Both mediums contain oxygen & carbon dioxide for gas exchange.

Gas exchange in the water mediums are more difficult than in the air medium

Solubility of oxygen in water is less than the air medium

Quantity of Oxygen into the air is 100 to 130ml per liter of air.

Quantity of Oxygen into the water is 0 to 10ml per liter of water.
