anatomical non-pathological anomalies known as variations which need to be able to be recognised. Physiology focuses on the systems and their organs of the human body and their functions. Many systems and mechanisms interact in order to maintain homeostasis. Skeletal structure frames the overall shape of the body and does not alter much over a lifetime. General body shape (and female body shape) is influenced by the distribution of muscle and fat tissue and also affected by various hormones. The average

function of the human body. The emphasis is homeostasis and the interrelationship among systems with discussions on selected pathologies. The first semester of the two part series covers the topics chemistry‚ histology‚ genetics and inheritance‚ and the integumentary‚ skeletal‚ muscular‚ digestive‚ and reproductive systems. General objectives: 1. To discuss a basic understanding and working knowledge of the human body. 2. To outline the concepts of homeostasis and interdependence of all body systems

The word “steroids” has more than one meaning‚ there are some steroids‚ which the body produces naturally as they are required through puberty and can help with stress management. Steroids can also refer to medicine taken for asthma‚ pain and skin problems. And then there are the steroids which are constantly being used in sport‚ they are synthetic drugs that are often used by professional athletes in order to increase the production of testosterone. They are available in pills‚ powder or injections

both at rest and during various forms of physical activity (McArdle‚ p.5). Carbohydrates serve several important functions related to exercise performance. The energy derived from the breakdown of glucose and glycogen is ultimately used to power muscular contraction as well as other forms of biologic work (McArdle‚ p.11).

Chapter 1 ELO’s Describe the basic functions of living organisms. A. Responsiveness – organisms respond to changes in their immediate environment (long term changes is adaptability) B. Growth – over a lifetime‚ organisms grow larger through an increase in size or number of cells. Differentiation is when cells have specialized functions C. Reproduction – Organisms reproduce‚ creating subsequent generations of similar organisms D. Movement – Organisms are capable of movement

sharper colors. Rod cells are found on the side while cones are found on the bottom. 3. Explain how the body maintains homeostasis of serum (blood calcium) levels through the use of the thyroid and parathyroid gland. The body maintains homeostasis of serum levels through the use of the thyroid and parathyroid glands because the thyroid secretes calcitonin and the parathyroid secretes parathyroid hormone. Both of these hormones help regulate blood calcium levels. 4. Explain
