return the body to homeostasis. When a person is in stress, these glucocorticoids do the same thing as if they were fighting an infection; however, if the body is in constant stress, it will continue to "fight the infection" and will not return the body to homeostasis. This can cause glucocorticoid receptor resistance and can cause the body to develop an even higher risk of depression, upper respiratory infections, diabetes, autoimmune disease, slower healing, and even cardiovascular disease (1).

Anatomy and Physiology Cell Organelles There are 50 trillion (50 million million) cells in the human body; they carry out chemical reactions essential to life, for example Blood cells. Nucleus The nucleus is the largest structure in any human cell, it contains gasps or pores, which allow protein and nucleic acid, pass through. It is the central part of the cell and it’s usually a lot darker than the rest of the cell because it absorbs stain quickly and stores the entire DNA (Deoxyribonucleic

Karen Pontifex TMA 1 1. Describe the four basic human body structure units and their functions The four basic human body structure units and their functions are: Cells, Tissues, Organs, and Systems. Cells Humans and all living things are made up of about 100 trillion small cells that can only be seen via a microscope. Cells can reproduce themselves and live independently. Some cells are specialized and become a different shape and size (elongated, oval, square, flat etc)

P5 - Homeostasis is ‘the process of maintaining a constant internal environment despite changing environments’ (Aldworth, Billingham, Moonie, & Talman, 2010). The internal environment that our body consists of is made up of blood, tissue fluid, body cell components and our metabolism and its process. Constant internal environment means that the chemical and physical composition should remain within a limited range in order to make it as effective as possible. Keeping the valuables within a limited
