Design a one-week corrective exercise program for a friend or client. Your program must include the following:
In: Anatomy and Physiology
1.Describe the pathway that air takes from the external environment to the alveoli during inspiration.
2. Describe the concept of a mucociliary escalator. where is the system found, and what adverse effects would occur if it was not present?
3. how is the opening of the trachea protected during swallowing
4. Describe the difference between external inspiration and internal inspiration
5.what is surface tension? why is surface tension potentially dangerous at the surface of alveoli? what reduces alveolar surface tension?
6. Describe the 2 phases of ventilation: inspiration and expiration. make sure to include activity of muscles involved, the pressure and volume of the lungs during each phase , and sources of neural control for these processes.

Part A:
Outline and paraphrase the negative feedback cycles involved in the development and maturation of sperm in the human male. Include the role of follicle stimulating hormone(FSH), luteinizing hormone (LH), androgen binding protein (ABP)and inhibin.
Part B:
Outline and paraphrase the negative feedback cycles involved in the development and ovulation of an egg in the female. Include the role of follicle stimulating hormone (FSH), luteinizing hormone (LH), estrogen and progesterone.

Provide one way in which glutamine/glutamate could be regulated
hormonally, in order to meet the needs of the organism. Start with
the hormone that would be used to send the message to the liver
cell that the blood glucose level is low, and run through the steps
of the amplification cascade in the liver (a sketch with
explanation would be useful), and conclude with one important
target enzyme and indicate how it would be affected (activated?
Inhibited? How?). Briefly explain the biochemical strategy of this
regulation.
