The Five Themes of Biology Transfer of energy: the movement of energy from one place to another‚ matter can not be created nor destroyed Bioheat transfer: heat transfer in biological systems. How heat moves from one compartment‚ be it within the body or external to the body‚ to another compartment in the body Osmosis: Water moving from high concentration to a low concentration Diffusion: Particles moving from high concentration to a low concentration Unity and Diversity: how things are similar

ANATOMY AND PHYSIOLOGY OF HUMAN HEART The human heart is a cone shape‚ hollow‚ muscular organ located in the mediastinum between the lungs. It is a about the size of an adult fist. The heart rests on the diaphragm‚ tilting forward and to the left in the client’s chest. Each beat of the heart pumps about 60ml of blood‚ or 5L/min. During strenuous physical activity‚ the heart can double the amount of blood pumped to meet the increased oxygen needs of the peripheral tissues. ANTERIOR VIEW

Question to answer after watching the Interactive Physiology - The Immune System: Innate Host Defenses 1. Name the two major categories of innate (nonspecific) defenses: • Surface Barriers • Innate Internal Defenses 2. Surface barriers include the Intact skin and mucous membranes of the respiratory‚ gastrointestinal and genitourinary tracts. 3. List the three properties of skin that help it resist invasion: • Keratin: tough protein in skin cells‚ forms an abrasion- and water-resistant outermost

Tissues in the Body Unit 5 – Anatomy and Physiology for Health and Social Care Epithelial Cuboidal – cube shaped‚ prominent nucleus. Can be found in medulla of kidney. Does not allow for passive diffusion easily. Columnar – tall‚ vertical‚ thick cells. Can be found in the small intestine. Does not allow passive diffusion easily. Active transport is needed. Move nutrients from intestine to blood = absorption! Can have microvilli to increase surface area. Squamous – large‚ thin and prominent

Biology assignment - In Vitro Fertilization. In Vitro Fertilization (IVF)‚ is the procedure whereby human babies are conceived‚ not in the womb but in a test tube or a Petri dish. This procedure has become one of the greatest developments in the world of medical technology. In Vitro Fertilization has given infertile couples the chance to conceive and bear a child from a full term of pregnancy. Without this procedure‚ their infertility would render them childless. There are many aspects of
