IB Biology Topic 6 Human Health and Physiology Introduction – The human body is composed of cells organize into tissues, tissues organized into organs and organs organized into an organ system. This chapter will cover some of the major organ systems of the boy and how those organ systems interact with each other = physiology. 6.1 Digestion Why do we digest food? – Here is the series of the events in order: ~Ingestion: You eat the food. ~Digestion: A series of chemical

Summary of the Anatomy of the Frog As in other higher vertebrates, the frog body may be divided into a head, a short neck, and a trunk. The flat head contains the brain, mouth, eyes, ears, and nose. A short, almost rigid neck permits only limited head movement. The stubby trunk forms walls for a single body cavity, the coelom (Anatomy of the Frog). All the frog's internal organs--including the heart, the lungs, and all organs of digestion--are held in this single hollow space (Anatomy of the

Protein digestion Protein metabolism denotes the various biochemical processes responsible for the synthesis of proteins and amino acids, and the breakdown of proteins (and other large molecules, too) by catabolism.Dietary proteins are first broken down to individual amino acids by various enzymes and hydrochloric acid present in the gastro-intestinal tract.[1] These amino acids are further broken down to α-keto acids which can be recycled in the body for generation of energy, and production of

also available in a light variant. The probiotic, Bifidis Regularis, is a microorganisms which is alive. These microorganisms are known as good bacteria and can be found in food and supplements. They are essential in protection against disease, digestion and a proper development of the immune system. Because the Bifidis Regularis is a unique probiotic that is developed by the Danone Group, Activia is the only product in the world that contains Bifidis Regularis. The Danone Group says that the Bifidis

(regulation its homeostasis) PrPSc The abnormal, disease-producing protein is called PrPSc (for scrapie) has the same amino acid sequence (primary structure) is monomeric and easily digested by proteases is multimeric and resistant to digestion by proteases When PrPSc comes in contact with PrPC, it converts the PrPC into more of itself These molecules bind to each other forming aggregates PrPC and PrPSc are isoforms (different forms of the same protein). Molecular models of the

there is an agreement of ethical standard when it comes to using animals in research. Each religion has concluded animal testing is moral so long as the animal does not suffer from unnecessary pain, and the results of research are truly beneficial to humans. In Christianity, the Bible’s account of creation, Genesis 1:26, explicitly states how man has rule over the creatures on earth. As stated before, this same idea is expressed in multiple world religions. These three essential world religions all
