uptake of Ca2+ from food. A rise in blood Ca2+ above the set point promotes release of calcitonin from the thyroid gland. Calcitonin exerts effects on bone and kidneys opposite those of PTH and thus lowers blood Ca2+ levels. The regulation of blood Ca2+ levels illustrates how two hormones with opposite effects (PTH and calcitonin) balance each other‚ exerting tight regulation and maintaining homeostasis. Each hormone functions in a simple endocrine pathway in which the hormone-secreting cells

students human anatomy and physiology. Physiology is the study of the process or function of living things. The major goals of physiology are to understand the response of the body to stimuli and understand how the body maintains conditions within homeostasis in various environmental conditions. The study of physiology consists of many different levels including cell physiology‚ organ physiology and systemic physiology. Students will be exposed to all of these levels starting at the cellular level and

The main systems of the human body are the nervous‚ endocrine respiratory‚ circulatory‚ immune‚ digestive‚ excretory‚ skeletal‚ muscular‚ and the reproductive systems. They all work together in harmony and unison to keep us alive. The nervous and endocrine systems are what control most of the body. The nervous system includes the brain‚ spinal‚ cord and nerves.

10.1 OVERVIEW OF MUSCULAR TISSUE Types of muscular tissue There are 3 types of muscular tissue: skeletal‚ cardiac‚ & smooth. All 3 may share some things but they differ from one another in their microscopic anatomy‚ location‚ & how they are controlled by the nervous and endocrine systems Skeletal muscle tissue function of most is to move bones of the skeleton (are few that attach to other structures ex--the skin). Muscle tissue is striated b/c alternating light and dark protein bands (striations)
