Have you tried any anatomy and physiology quizzes lately? Anatomy and physiology is possibly the most exciting subject you can learn about. It’s amazing how our bodies are created from such a simple thing like a cell and grow into these wonderful and complex mechanisms capable of sustaining life.
For students of medicine it’s important to understand anatomy and physiology but it’s also an important matter to any one who wants good health and fitness and it’s just plain interesting too. To understand the human body is a complex matter and information is always being updated so it can be a daunting task to learn how it all works, but it’s worth investing the time as knowledge of the body will always be valuable and not just for answering quiz questions.
If you’re a student you may need an extra boost to prepare for exams and a good way to get it is through anatomy quizzes online like anatomy and physiology quizzes muscles and anatomy and physiology quizzes blood. There are also some very good anatomy and physiology study guides available.
If you’re new to the subject antomy and physiology here is a brief over view of the organism we call our body and how it all works:
What is the human body?
Human beings are one of the most complex organisms in nature made up of billions of tiny parts each with it’s own purpose but still working together as an organized whole.
Our bodies are made up of four major kinds of structures:
Cells – Our body begins as a single fertilized cell. Cells are the simplest units of living matter that can reproduce.
Tissues – Are a collection of cells with similar purpose.
Organs – Are a collection of tissues that work together to perform a specific function such as the stomach.
Systems – An organization or organs that work together to sustain the body such as nervous system.
Our bodies are made up of ten systems which are the Muscular system, Reproductive system, Endocrine system, Lymphatic system, Cardiovascular system, Respiratory system, Urinary system, Skeletal system, Digestive system and anatomy and nervous system.
The internal organs known as viscera are housed in the spaces or cavities of the body and there are two main cavities; ventral and dorsal. The larger cavity, the ventral, encompasses the chest and abdominal and pelvic region and houses the lungs and lungs, trachea and esophagus and also the intestines and kidneys and other major internal organs that we know as our “guts”. The smaller cavity, the dorsal, houses the brain and spinal column.
The body’s functions
The body’s functions are essentially its cells functions and survival is the main priority. Survival means maintaining a constant environment with in the body which is called homeostasis. Body temperature, chemical composition and pressure must remain relatively constant for your cells to be in a healthy condition and this means that your body is constantly carrying out many activities.
The major functions of your body are ceaselessly responding to changes in it’s environment and integrating all of the diverse activities that are being carried out including metabolizing foods and exchanging materials between cells and organs.
Every one knows that a body’s function decrease as you get older but it also performs its function the least effectively in infancy. Bodily functions gradually become more efficient during childhood and decrease in effectiveness in late maturity and old age. They usually operate with maximum efficiency during Young adulthood.
No part of the body works in isolation. From the smallest cell to the complete body system; all of the body’s functions are coordinated and interrelated. Diseases represent a disruption in the fine tuned balance between these processes. The basic processes of life include organization, metabolism, responsiveness, movements, reproduction, growth, differentiation, respiration, digestion, and excretion. However these ten processes alone are not enough to survive. The human body also requires external factors such as nutrients, water, oxygen, pressure and heat.
As you can see the human body is an amazing machine and well worth looking into. Who knew that there was so much going on under the hood? Anatomy and physiology is a fascinating subject. Why not try taking some of the anatomy quizzes online available? You should also take a look at some of the excellent study guides we offer.
