Body cavities and membranes

Body cavities and membranes In most cases, the body is described as having two main cavities called the “dorsal and ventral body cavities”. Some anatomical references do not recognize the dorsal body cavity but we will use it in this example because it’s used by many professionals and colleges. It also makes it easier to […]

The Language of Anatomy: anatomical position and directional terms

Anatomical position and directional terms The healthcare industry has its own terminology, especially anatomy and physiology. In order to provide exquisite care and understand the inner workings of the human body, anatomical terminology is a necessity. We’ll begin by going over “anatomical position and directional terms”. In order to describe body parts and positions correctly, […]

Homeostasis: positive/ negative feedback mechanisms

If you study biology or medicine, having a solid understanding of homeostasis is extremely important. All living systems are based on maintaining an internal environment and equilibrium. In homeostasis, positive and negative feedback mechanisms balance inputs, outputs, and responses. Most control mechanisms use a negative feedback loop, but some, like childbirth would be considered positive feedback.

Maintaining Life: Necessary Life Functions

Necessary Life Functions We recently discussed the structural levels of the human body. Next, we’ll take a look at what it actually does. Like all complex animals, humans must maintain a core set of necessary life functions to survive. These include maintaining boundaries, movement, responsiveness, digestion, metabolism, excretion, reproduction, and grow. In order to survive, […]

A&P: Levels of structural organization

One of the basic concepts in anatomy and physiology is the idea of organization. Levels of structural organization in the human body work from simple to complex, or small to large. For instance, the simplest level, or “chemical level”, consists of atoms and molecules. The highest and most complex level of organization, the organismal level, represents the sum total of all structural levels working together in unison.
