Learning objectives
Understand how the application of Physico-chemical principles to cellular functions is essential in understanding cellular mechanisms.
Examine body function at all level, from cell to organ, examining how different system work together to maintain coordinated functions
Expected learning outcomes
Students are expected to enhance their knowledge, and logical and critic skills that will allow a rigorous scientific understanding of physiological topics to approach toxicological issues. Capability to recognize physico-chemical basis of phenomena, broadening ability of exposition of concepts and description of problematics are expected as well
Course syllabus and organization

Single session

Lesson period
First semester
More specific information on the delivery modes of training activities for academic year 2021/22 will be provided over the coming months, based on the evolution of the public health situation.
Learning verification : The exam is oral and takes place with the use of the Teams platform.

Prerequisites for admission
To take the exam of Physiology, students must have passed Physics, Biology and Anatomy, and General Chemistry
Teaching methods
The course is based on frontal teaching, by using slides and/or videos. Material of lectures will be provided on UNIMI-Ariel website.
Teaching Resources
Luciano Zocchi "Principi di Fisiologia"- II edizione-EdiSES
Silverthorn «Fisiologia umana. Un approccio integrato» settima edizione Pearson
Assessment methods and Criteria
Oral exam organized into three questions that require the discussion of the proposed topic and the ability to connect it to other topics so as to evaluate, in addition to the knowledge acquired, the ability to reason and the acquisition of a correct scientific language . The exam lasts about thirty minutes and the mark is expressed out of thirty.
