positive cooperativity. A representation of the isotonic contractions of the ileum can be seen in Appendix‚ Figures 1 and 2. Figure 2 illustrates the response of the Guinea Pig ileum through isotonic contractions when a dose of ACh is added into the organ bath with a competitive antagonist. A relationship between response and bath concentration can be identified through the clear sigmoidal formation observed in Figure 2. The responses ranged from 0-100% while bath concentrations ranged from 2 x 10-10

The Senses The sensory system involves hearing‚ touching‚ tasting‚ smelling‚ and seeing‚ which provide data for perception. The eye is a sensory organ held by an orbit that allows vision (a detection of light in a way that provides mental images of objects) and holds photoreceptors. Photoreceptors are used to absorb light energy‚ which are bent by a transparent unit called the lens. Some photoreceptors in the eye are the rod cell and cone cell. Rod cells are used in dim light for coarse images and

Body Systems of Various Organisms All organisms in the world have a range of systems and organs in their body. Some organisms may share similar body systems while others have absolutely nothing in common. Several of those organisms include humans‚ pigs‚ crayfish‚ and earthworms. From their mushy‚ gushy organs to their soft‚ gentle skin‚ you may think‚ “How are humans and pigs possibly alike? Or a crayfish and an earthworm?” In many ways they may not be‚ but in other ways‚ they are very much alike

accepted anatomical position when studying the structure of humans. It is important to have a universally accepted anatomical position when studying human structure to limit confusion when describing the human body’s direction or location of organ or bones. When the body is in anatomical position the body is standing erect‚ feet are shoulder width apart‚ toes are pointing forward‚ arms are down by the sides‚ and the palms are facing forward.

Planarians are hermaphrodites- they have both male sex organs (testes) and female sex organs (ovaries). When two planarians reproduce sexually‚ they simultaneously fertilize each other. Their eggs are laid in protective capsules that stick to rocks or debris and hatch in two or three

Muscular System‚ Nervous System‚ Reproductive System and Respiratory System. The human body is a complex collection of various systems‚ which work together to make us live our everyday life. The human body consists of biological systems that consist of organ‚ tissues and connective tissue. The Cardiovascular system is made up of the heart‚ blood vessels e.g. arteries‚ veins and capillaries (small blood vessels).

The history of anatomy is described by a progressive understanding of the organs and the structure of the human body. The discipline of anatomy is divided into microscopic and macroscopic anatomy.
