Introduction to Human Anatomy and Physiology
Part A 2. Distinguish between the activities of anatomists and physiologists.
Anatomists deal with the structure (morphology) of the body parts. This includes the shapes, forms, and placement of body organs and appendages. Physiologists deal with the functions of body parts, what the body parts do, and how this is accomplished. 3. How does a biological structure’s form determine its function? Give an example.
The functional role will depend upon the manner in which the part is constructed. The human hand with its long, jointed fingers makes it possible for human beings to grasp things. 4. List and describe the ten characteristics of life.
Movement is the ability to self-initiate position changes of either the entire organism or a part of the organism, externally from place to place and/or internally, such as in peristalsis.
Responsiveness refers to the ability of an organism to detect changes either within itself or the environment surrounding it and then react to these changes.
Growth generally refers to an increase in body size without important changes to its general shape.
Reproduction is the process of making a new organism, as in parents producing offspring. It also discusses the process whereby cells can produce others like themselves to take the place of damaged or destroyed cells.
Respiration refers to the process of obtaining oxygen, using the obtained oxygen in release of energy from foods, and removing waste gases that are produced in the process.
Digestion is the chemical change of ingested foods into simpler substances that can be taken in and used by body parts.
Absorption is the passage of digested substances through membranes 5. Define metabolism.
The totality of chemical changes that occur within body parts. 6. List and describe five requirements of organisms.
Water, the most abundant substance in the body,
