Introduction
The physics of biological processes connects biology with physics. From a knowledge of the functioning of a biological process or the physiology of the organ or system that performs it, the associated area of physics is revealed, its concepts, parameters and laws that are applied.
The course provides students with a general, basic knowledge of the biological process, the physiology of the organ or system (if necessary) and the physical laws involved. The different topics are developed so that the student has a basic descriptive knowledge of the underlying physical phenomenon and how it affects the biological process. The physical phenomena (sound, vision, ionising radiation, etc.) that have given rise to the technology of medical application are explained in order to understand their basic principles, methodology, the tools that they provide and, where appropriate, the associated basic protection standards.
Objectives
The main objective of this subject is to introduce the student to the characteristics and peculiarities of the physics of biological processes, as well as the damage and benefits that this can cause.
Specific objectives
• Connect biological processes with the physical processes that govern them.
• Recognise the physical laws which impact on the basic biological systems, which parameters are important and how they are related to ensure the operation of the process.
• To become familiar with the mathematical expressions that govern the physical processes in order to be able to explain the biological process through its use.
• Relate basic diagnostic or medical therapy technologies to their physical principles and their impact on the biological system (ultrasound, magnetic resonance imaging, radiology, etc.
• Relate the physical concepts with the correction and improvement equipment that is applied to biological systems that have structural or functional defects (visual, hearing correction systems, etc.)
• Show the effects that physical phenomena used in medical technology can have on biological systems and, where appropriate, what protection mechanisms should be applied (protection against ionising and non-ionising radiation, etc.
Develop in a physics laboratory. Become familiar with the measuring instruments. Interpret schemes and turn them into real experiments. Take results, evaluate them, draw conclusions about them, evaluate errors and their management and translate the results into scientific writings: technical reports, scientific posters, scientific articles, scientific and audiovisual presentations.

Teaching and learning activities
In person
The teaching resources used in this subject are the following:
Master Class (CM): Exhibition for two hours (with a 10-minute break) of a theoretical topic by the teacher with audio-visual support based on presentations projected from the computer. The student will have the contents in advance through the Moodle. Attendance is not mandatory but highly recommended.
Case method (MC): Depending on the topic to be addressed, problem-solving activities or specific development activities of areas set forth in the master classes are proposed. In the classroom and for a short time, the resolution of the problem or topic will be presented with the help of the available audio-visual support. The student will be given time to finish the activity. It is possible that they may have to finish it outside of class time.The students will submit the works for evaluation through moodle before the end of the day in which the MC is developed. After that period of time, the works cannot be delivered. Students who do not correspond to the first call are exempt from presenting the work (the grade obtained in the first call will be taken).Attendance is mandatory except for students who do not correspond to the first call.
Practices (P): Familiarization of students with the basic techniques of work and handling of measurement equipment in the field of physics. Demonstration in the laboratory of some aspects raised in the master classes. Consolidation through practice of the most important aspects dealt with in the theoretical classes. The students are organized in small groups for the development of the practice. Each group must carry out the work and activities of the practice that will be delivered at the end of each practice for evaluation.
Continuous assessment exercises (CE): As an evaluative element of comparable importance to the final exam and complement to the master classes and the MC, each week activities such as problems, questionnaires or other types of tasks related to the topic developed in the master class will be proposed. These works are for individual delivery and must be submitted through the moodle platform before the next master class. These works will be evaluated and have a minimum grade required to pass the subject.
Evaluation systems and criteria
In person
Attendance
Attendance to master classes will not be mandatory.
Attendance to the case methods and practices is mandatory except for students who are not in the first call. Non-attendance, due to health reasons or force majeure, must be justified in writing. The non-justification of the absence or cause not considered of health or force majeure will lead to receiving a grade of 0 in the work of the case method or the corresponding practical session.
A control of attendance by signature will be carried out in the methods of the case and in the practices.
Presentation of works and evaluation
Case methods
The papers corresponding to the case methods will be evaluated as long as they are submitted within the established deadline and in the established format.
Students who are not in the first call will not have to present the work, the grade obtained in the first call is kept.
No minimum grade is established to access the continuous assessment. The grade obtained will be saved for subsequent calls, if applicable.
Practices
The works corresponding to the practices will be evaluated whenever they are presented within the established term and in the established format.
Students who are not in the first call will not have to present the work, the grade obtained in the first call is kept.
No minimum grade is established to access the continuous assessment. The note obtained will be saved for subsequent calls, if applicable.
Continuous assessment exercises

Time available 60 minutes.
During the execution of the exam, students will not be able to have forms, notes, textbooks, sources of electronic support or any type of external help. Violation of this rule will lead to expulsion from the exam, the assignment of a grade 0 to the exam and communication of the fact to the direction of the grade. If they will be able to have a non-programmable scientific calculator.
The minimum mark of 5 is established to access the continuous evaluation of the second call. Obtaining a grade lower than 5 will not allow passing the subject in the second call and will force the student to take future calls.
Final exam of second call problems
All students with a grade of less than 5 in the continuous assessment exercises must take the second call problem exam.
In case of no presentation, the grade assigned to the student will be zero.
