Anatomy Physiology Lab Report: The Permeability of Cell Transport Mechanisms

If the solution in the left beaker contained both urea and albumin, which membrane(s) could you choose to selectively remove the urea from the solution in the left beaker? How would you carry out this experiment?

There are many kinds of body systems, working together to create a functioning body. Different body systems work with certain body systems, but all work together. Like, nervous system and muscular system, circulatory system and respiratory system, and so on.

The purpose of these experiments is to examine the driving force behind the movement of substances across a selective or semiperpeable plasma membrane. Experiment simulations examine substances that move passively through a semipermeable membrane, and those that require active transport. Those that move passively through the membrane will do so in these simulations by facilitated diffusion and filtration. The plasma membrane’s structure is composed in such a way that it can discriminate as to which substances can pass into the cell. This enables nutrients to enter the cell, while keeping unwanted substances out. Active

have a variety of systems due to the complexity of the species' organism. The human body

In this task I will be examining how the different body systems use energy and why the body needs energy. I will also be analysing cellular respiration which is the process in which energy is made, along with the by-products and anabolism and catabolism. Later on in this task I will be analysing how ATP is used in muscle action, protein production and how we as mammals use the energy released as heat.

The body has different organs that work together and they make up a system such as the

Many of the systems in the body are delicate. They function only under a specific range of parameters.

In this assignment I will be describing the microstructure of a typical animal cell and the functions of the main cell components. Describing and explaining the factors the ways in which materials move in and out of cells. I will also be analysing the role of the phospholipid bilayer in terms of movement of materials in and out of cells.

In this assignment I will be explaining the physiology of the cardiovascular system and the respiratory system. Whilst explaining the two body systems I will be explaining energy production, process of cellular respiration, the role of enzymes within these body systems, the way that these systems absorb food and the products of digestion.

The two systems are such close partners that they are explored together in this chapter

The topics is covers are: principles of medicine, immunologic system, hematologic system, cardiovascular system, respiratory system, urinary system, gastrointestinal system, neurologic system, Behavioral science, endocrine system, reproductive systems, musculo-skeletal system, integumentary system, multi-organ synthesis. Topics such as anatomy, nutrition and behavioral sciences are integrated throughout the blocks.

All cells contain membranes that are selectively permeable, allowing certain things to pass into and leave out of the cell. The process in which molecules of a substance move from an area of high concentration to areas of low concentration is called Diffusion. Whereas Osmosis is the process in which water crosses membranes from regions of high water concentration to areas with low water concentration. While molecules in diffusion move down a concentration gradient, molecules during osmosis both move down a concentration gradient as well as across it. Both diffusion, and osmosis are types of passive transport, which do not require help.

The human body system is a complex system in which all of the disjointed organ systems need to work together to keep the body running. Since the organ system is interdependent, it is impossible for one body system to be more important than the other. Each of the individual systems collaborate for a common purpose which is to depend on one another to do the job there is to be done in order for the body to function. Not one system is able to do the job alone- each segment falls into order and carry out specific duties in the body.
