Basic functions shared by all living things
respond to changes in the immediate environment, Organisms show adaptability, Over time, organism grow and reproduce, many organisms are capable of some degree of movement.
involves the examinaton of relatively large stuctures and features usually visible with the unaided eye.
The link between anatomy and physiology
All specific functions are performed by specific structures.
Structure and function are interrelated
Anatomical details are significant only because each has an effect on function, and physiological mechanisms can be fully understood only in terms of the underlying structural relationships.
Function of the elbow joint to a door hinge.
The elbow functions as a hinge that permits movement only in one plane.The end of the humerus, the bone of the upper arm, has a roughly cylindrical articulating surface. With this interlocking arrangement, which is stabilized by ligaments and surrounding muscles, only hinge-like movement is permitted.
Usually refers to the absorption and utilzation of oxygen, and the generaton and release of carbon dioxide.
Movement of fluid within the organism; may involve a pump and a network of special vessels.
Distributes materials throughout large organisms; changes orientation or position of a plant or immobile animal; moves mobil animals around the environment.
Indicates that the organism recognizes changes in its internal or external environment.
Examples of Physiology
Valve to arota opens, valve between left atrium and left ventricle closes,Electrocardiogram, Pressure in left atrium.
Basic principles of the cell theory
Cells are the structural building blocks of all plants and animals, Cells are produced by the divisions of pre-existing cells, Cells are the smallest structural units
All forms contain cells and an extracellular matrix that consists of protien fibers and a liquid known as the ground substance.
Ability ot contract forcefully. Major functions include skelatal movement, soft tissue support, and maintance of blood flow.
Integumentary, Skeletal, Muscular, Nervous, Endocrine, Cariovascular, Lymphatic, Respiratory, Digestive, Urinary, Reproductive
Either flattened dics or roughly spherical. Most abundant cells in the body. Transport oxygen and carbon dioxide in the bloodstream.
Reside within small cavities inside the mass of the bone. Responsible for maintenance of the bone and for recycling the calcium and phoshate stored there.
Roughly spherical storage containers. Whenever we take in more energy than we expend, the excess energy obtained from the food gets stored.
The adjustment of physiological systems to preserve homeostastsis in environments that are often inconsistent, unpredictable, and potentially dangerous.
Which recieves and processes the information supplied by the receptor, and which sends out commands.
Occurs when receptor stimulation triggers a response that changes the environment at the receptor.
The primary mechanism of homeostatic regulation, and it provides long term control over the body's internal conditions and systems.
