Physiology has traditionally been divided into plant physiology and animal physiology but the principles of physiology are universal, no matter what particular organism is being studied. For example, what is learned about the physiology of yeast cells can also apply to human cells.

## Physiology

[edit | edit source]

Main article: Physiology

Physiology is the study of the mechanical, physical, and biochemical functions of living organisms.

Def. a "branch of biology that deals with the functions and activities of life or of living matter (as organs, tissues, or cells) and of the physical and chemical phenomena involved"[1] is called a physiology.

Physiology is the scientific study of the functions and mechanisms which work within a living system.[2][3]

As a sub-discipline of biology, the focus of physiology is in how organisms, organ systems, organs, cells, and biomolecules carry out the chemical and physical functions that exist in a living system.[4]

## Animals

Animals are heterotrophic eukaryotic organisms which ingest food.

Def. "a multicellular organism that is usually mobile, whose cells are not encased in a rigid cell wall (distinguishing it from plants and fungi) and which derives energy solely from the consumption of other organisms"[5] is called an animal.

## Theoretical animal physiology

[edit | edit source]

Here's a theoretical definition:

Def. a branch of zoology that deals with the functions and activities of single or multicellular organisms that are usually mobile, whose cells are not encased in a rigid cell wall and which derive energy solely from the consumption of other organisms, and of the physical and chemical phenomena involved is called an animal physiology.

## Functionings

[edit | edit source]

Central to an understanding of physiological functioning is the investigation of the fundamental biophysical and biochemical phenomena, the coordinated homeostatic control mechanisms, and the continuous communication between cells.[6]

"All humans are capable of producing the same wide range of vowel sounds."[7]

"Huh? is the product of convergent evolution. This term refers to the independent evolution of similar structures in unrelated species."[7]

"Huh? has a similar form across languages because the same set of conditions leads in all languages to something like the Huh? word being produced. In the flow of conversation, people need to be sure that others know when they have failed to understand. Time runs by quickly in conversation, and there is only a short window in which to signal a comprehension problem. In that situation, one needs a syllable that is fast and easy to pronounce. Huh? does the job. The particular vowels that Huh? is restricted to in all languages happen to be the vowels that are most easily pronounced when a person’s tongue is in a relaxed position."[7]

## States

[edit | edit source]

The physiologic state is the condition occurring per normal body function, while the pathologic state is centered on the abnormalities that occur in animal diseases, including humans.[8]

## Types of organisms

[edit | edit source]

According to the type of investigated organisms, the field can be divided into, animal physiology (including that of humans), plant physiology, cellular physiology and microbial physiology.[4]

## Killer whales

The image on the left show the approximate location of the organs: melon, blowhole, esophagus, brain, lung, heart, sternum, liver, stomach, intestines, kidney, bladder, vagina, and colon.

The image on the right shows the basic external anatomy including dorsal fluke, dorsal cape, caudal peduncle, caudal fin, belly spot, pectoral fins beak, melon, and white eye patch.

On the skeleton in the center, note the four fingers (two are fused of the original five).
