Physiology Case

Organism Physiology

Life organisms structure are a hierarchy of cells, tissue, and organs categorized in the order of precedence. Cells group into tissue, and grouped into organs. Organ functions turn to organ systems and collectively make the living organism. (Simon, Reese, Dickey, 2010).

Hierarchy performs to create the form functions essential for organism existence. Anatomy is the study of organisms and physiology is the study of organism function. Collective functions and categories will discuss how mice organisms function and evolve to the environment. See Figure A.

Anatomy is the study of organism structure and physiology is the study of the structure function. Living organisms are make various parts that makes them function. Like humans the majority of animal body makeup is water and a protective structure like a skeleton. Additionally the organ systems throughout the body forms circulation and digestion. This is the form function principle.

Cells are multi-cellular cells that create tissues. Organs in vertebrates, (mouse) make different tissues types, which function as organ systems in different body systems. The four tissue types are epithelical, connective, muscle, and nervous. (Outline, b 2013).

Epithelical tissue closely pack single or multiple cells that align the internal and exterior surfaces. They can cube shaped, elongated or flat. Connective tissue fill space, bond, store fat, and allow elasticity. It plays a vital role with loose and fibrous tissue. Fibrous tissues are tendons and ligaments. They lay under skin as protectants of muscle fibers and blood vessels. (Farabee M, 2006).

Blood cells red and white are connective tissue. The blood is separates by plasma that removes residual glucose, waste, carbon dioxide, and regulates the amount of water.(Farabee M. 2006).

Muscle tissue orchestrates animal movement by contracting individual muscle cells known as muscle fibers. Vertebrates have three fibers skeletal, smooth, and cardiac. Cardiac fibers surround and protect the respiratory system, skeletal muscle fibers are for individual movement. Smooth muscle are involuntary movement like secretion, ejaculation, and various reflexes (Farabee M. 2006).

Nervous tissue transmits and control nerve and stimulus messages. They are derive from neuron cells. (Farabee, M. 2006).

Different organ systems such as nervous, respiratory, and digestive are form from multicellular organisms. They all function as hierarchy internally.

They work simultaneously for existence. The variables of organ systems change or fluctuate to stay operational is known as homeostasis.
