The Structural Organisation of the human body
As an organism we are extremely complex. We are made up of trillions of cells, that perform many functions, specialising. Cells help us to sense, protect, produce, receive, conduct, secrete, produce, distribute and to permeate.
Tissues and organs that work in tandem to perform specific functions within the human body, in short that is what a system is. Here we list ten identifiable systems:
- Nervous system
- Digestive System
- The Skin
- The reproductive system
- The Endocrine System
- The Digestive System
- The Urinary System
- The Respiratory System
- The Circulatory System
- The Skeletal System
As stated by The Editors of Encyclopaedia Britannica (2020) “Organ, in biology, isa group of tissues in a living organism that have been adapted to perform a specific function”So basically within us! Basically, the tissues within an organ are adapted so it can perform its task.
There are four main types of tissue. Muscle, Nervous, Connective and epithelial. All having a common function.
This type of tissue lines the outer surface of your organs and all the blood vessels within your body. There are 6 types’ simple squamous epithelia, simple cuboidal epithelia, simple columnar epithelia, stratified squamous epithelia, stratified cuboidal epithelia and stratified columnar epithelia. Forming together to form sheets of tightly packed cells.
Playing an important in protection, absorption, excretion and sensation. As it is barrier between the body and the outside (external) environment.
Connective tissues within the body are vast and varied. These can include ligaments, tendons, muscle fascia, adipose tissue (fat.), blood, cartilage and bone to name a few! Connective tissue helps to support, protect however they can also help to insulate as well as transport. The function and location of connective tissue tends to be I keeping with the bodies needs. For example, when its needed to be protective such its hard and dense, when it’s for example in blood vessels it needs to be expandable.
Designed when stimulated to contract to enable/create movement. long and narrow in presentation often referred to as fibres.
The nervous system is comprised of nervous tissue. The function of nervous tissue is to receive and transmit messages to enable the body to move and co-ordinate. This can be under conscious or unconscious control or voluntary and involuntary control.
Meaning little organ, “organelle’. A specialist part of a cell with a specific function. They can differ from cell to cell, just dependant in what is required. Although some are common as within all animals, include human.
