Question #1 Pre-load can be defined as the degree to which cardiac (heart) muscle cells extend before contraction in the heart. Pre-load is one of the factors that affect the stroke volume. It directly relates to stroke volume. The way it works is that a rise in venous return to the heart raises the end diastolic volume of the ventricle which causes the muscles fibers to stretch thus increasing preload. Also‚ it increases the force of contraction of the ventricles making the heart to discharge

Homeostasis is the ’maintenance of equilibrium in a biological system by means of an automatic mechanism that counteracts influences tending towards disequilibria’. Homeostatic mechanisms operate at all levels within living systems‚ including the molecular‚ cellular‚ and population levels. in humans homeostasis involves the constant monitoring and regulating of numerous factors including‚ oxygen and carbon dioxide levels‚ nutrient and hormone levels and inorganic and organic substances.

Homeostasis literally means “same state” and it refers to the process of keeping the internal body environment in a steady state‚ when the external environment is changed. The importance of this cannot be over-stressed‚ as it allows enzymes etc to be ‘fine-tuned’ to a particular set of conditions‚ and so to operate more efficiently. Much of the hormone system and autonomic nervous systems is dedicated to homeostasis‚ and their action is coordinated by the hypothalamus. In Module 2 we saw how

secreted by the posterior pituitary is antidiuretic hormone or ADH. This hormone helps prevent excess water excretion by the kidneys. Ethanol inhibits the release of ADH and can‚ thus‚ cause excessive water loss. That’s also part of the reason why a group of college students who go out for pizza and a pitcher of beer need to make frequent trips to the restrooms. Diuretics are chemicals which interfere with the production of or action of ADH so the kidneys secrete more water. Thus diuretics are often
