Ovarian Cycle Follicular Phase ↓ Est‚ ↓ Prog → ___ FSH release FSH → granulosa cells secrete ____ The major follicle will secrete the most estrogen and inhibin which will have a negative inhibition on FSH‚ LH and GnRH release (this will allow a greater chance of only one follicle maturing) When Est levels are highest → will switch to a positive feedback and stimulates ↑↑ secretion of LH‚ FSH and GnRH. Meanwhile‚ the follicle is also secreting a little Prog which stimulates GnRH and ↑ LH release

Answer the question in the space provided for each question. 1. In the PHYSIO-EX 9.0 Activity 1‚ the simulation showed you how the resting membrane potential depends on the concentration of K+ and Na+ in the ECF. Some data were generated while measuring the resting membrane potential

Regulation of the cardiovascular system by examining changes in heart rate Prepared for Dr. Isabelle Lys Lecturer of SBI171 Anatomy &Physiology Charles Darwin University Summer Semester 2012-2013 Introduction Every day the human body is involved in various tasks which can alter a person’s heart rate. Some internal and external factors that contribute to changes in HR are thermo-regulatory changes‚ diurnal changes and sudden postural changes‚ which are among others

Describe the physiology of the cardiovascular system in relation to energy. A.T.P is stored‚ chemical energy in the cell‚ without A.T.P we would die. To make A.T.P we need glucose oxygen. Carbon dioxide and heat are the waste products. The main function of the cardiovascular system in relation to energy is to transport the oxygen and glucose to the cells‚ and to transport the waste products such as carbon dioxide and urea (waste product from protein digestion) away from the cells and to the lungs

series of integrated changes in function that involve most‚ if not all‚ of its physiological systems. Movement requires activation and control of the musculoskeletal system; the cardiovascular and respiratory systems provide the ability to sustain this movement over extended periods. When the body engages in exercise training several times a week or more frequently‚ each of these physiological systems undergoes specific adaptations that increase the body’s efficiency and capacity. After a twelve

Through endocrine signaling‚ the signaling molecule or hormone is produced by a gland and discharged into the blood where it travels until it reaches certain blood cells distant from its place of origin on which it exerts its action. This is a long distance communication process. The signaling molecule is mainly of protein origin‚ although there is also a varied range of steroidal hormones.

Chapter 1 - The Human Body Anatomy is the science relating to the structural organisation of living organisms. Physiology is the science relating to the operational functions of living organisms. The many parts and systems of the body are integrated and function co-operatively to provide a healthy living body via 6 hierarchy levels of structural organisation. The basic or first level is the Chemical Level‚ where atoms are combined to form molecules. The second level is the Cellular Level
