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 […]
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, […]
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.
Can you name the 11 organ systems of the human body from memory? If not, this may be a good refresher read for you and a great place to start for beginners! In this article, we review and discuss the 11 organ systems of the body. The main focus is anatomy and which organs makeup each particular organ system, but we will briefly discuss each organ systems main function and role within the body also.
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, […]
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.
An overview of Anatomy and Physiology Welcome to the wonderful world of Anatomy and Physiology! The subject can be a challenge in college but the payoff is well worth it. Learning about the inner workings of the human body may seem like a daunting task, but in order to understand emerging technologies and breakthroughs taking […]
