Study Notes
Transport Mechanisms in Living Cells
- Efficient transport mechanisms are essential for the exchange of substances, nutrients, and waste products between cells and their environment.
Body Fluids in Higher Organisms
- In higher organisms, including humans, blood is the primary body fluid used for the transport of materials.
Transport in Simple Organisms
- Simple organisms like sponges and coelenterates facilitate the exchange of substances for their cells through direct diffusion between cells and the surrounding environment.
Role of Lymph
- In higher organisms, lymph plays a role in the transport of materials, in addition to blood, and is also responsible for defending the body against infection and disease.
Functions of Body Fluids
- The following are functions of body fluids: transport of materials, regulation of body temperature, and defense against infection and disease.
- Excretion is NOT a function of the body fluids mentioned in the text.
Circulating Water in Simple Organisms
- Circulating water through the body cavities in simple organisms like sponges and coelenterates facilitates the exchange of substances and nutrients between cells and the surrounding environment.
Transport in Simple vs. Complex Organisms
- The primary difference between the transport of substances in more complex organisms and that in simple organisms like sponges and coelenterates is the presence of specialized transport systems, such as blood and lymph, in complex organisms.
