WebThe structures of leaves are adapted for efficient photosynthesis as shown in the table below. Most leaves are broad and so have a large surface area allowing them to absorb more light. A thin shape means a short distance for carbon dioxide to diffuse in and oxygen to diffuse out easily. This chemical gives the leaves their green colour and ... WebBoth the gill filaments and lamellae provide a large surface area for gaseous exchange, increasing the efficiency of diffusion .The lamellae have many blood capillaries and a thin surface layer of cells (or epithelium), this means there is a short diffusion distance .The blood flows through the lamellae in one direction and the water flows over …

WebMost animals and plants consist of different types of cells organised as tissues, organs and systems. The human respiratory system is a body system adapted for efficient gas … WebThe lungs are specifically adapted for gas exchange (diffusion) - meaning the lungs allow oxygen into the blood stream and carbon dioxide out. To ensure our cells can respire properly, we want fast and efficient gas exchange. The lungs contain many 'tubes' or airways that carry air in and out of our lungs.
