Chapters 34 41 and 44 Go back We fked everything up Humans and Apes Homo sapiens characteristics Bipedal Larger brains Language Symbolic thought Artistic expression Use complex tools. WHY USE SIMULATION?. Anaerobic digestion is a highly complex process containing numerous biological and chemical reactions taking place simultaneously. The stability of an anaerobic digestion system depends on the composition of the substrates and how microorganisms themselves convert the given substrates. . EXCRETION. HOW DO WE REMEMBER ALL THE LIFE PROCESSES?. H.N.T.R.S.G.E.R.M.R. WHICH ONES HAVE WE COVERED?. NUTRITION & TRANSPORT & RESPIRATION. WHAT’S NEXT ON THE LIST?. WHY ARE WE SKIPPING TO “E”?.

Simple type of digestion which occurs inside the food vacuoles in the cytoplasm of the cell.. WHAT YOU WILL LEARN IN THIS UNIT:. Identify major structures and functions of the human digestive system from a diagram, model, or specimen. .  . Describe the processes of mechanical digestion that take place at various sites along the alimentary canal. Nephron structure and function. Urine production . What is Excretion?. Excretion is the process by which metabolic waste and harmful substances are removed from the body. . These wastes are produced by chemical reactions occurring inside body cells (metabolism) . Structural Adaptations. of. Organisms. The break down of glucose to create ATP energy for cells. Occurs in the . mitochondria. Accomplished in various ways:. Ex.. Single-celled organisms(diffusion).

Defined as the passage of a drug from its site of administration into the plasma. Therefore, it is important for all routes of administration, except intravenous injection. 267 The digested end products are absorbed into the body through the epithelial liningof the intestinal villi. The undigested food (faeces) enters into the caecum of the largeevents the back flow of t 1. Chapter 3. Nutrient Digestion and Absorption. 2. Food Nutrient Digestion and Absorption. The Digestive Process. Digestion = mechanical and chemical food breakdown of food for absorption into blood for use, storage, or chemical change.
