Introduction
This essay will firstly outline the main anatomical features of the human body. Secondly, it will explain how the body systems interact with each other, to ensure the body functions and develops. References of relevant literature will be used throughout the whole essay.

Principles of physiology
Task 1

List all the systems of the human body and their functions. Explain how body systems interact to ensure proper functioning and growth of the human body.

The human body main anatomical features are:

* Central Nervous system
The central nervous system consists of the brain, spinal cord and a network of nerves. This system is responsible for sending, receiving, and interpreting information from all parts of the body. This system has full control over all other systems.
* Cardio Vascular/Circulatory system
The cardio vascular system is a network made up of the heart, blood, blood ...view middle of the document...

Other organs play a part in the digestion of food such as the liver. This system provides nutrients to other systems to help them grow and function normally.
* Urinary System
The urinary system consists of two kidneys, two ureters, two sphincter muscles, the bladder and the urethra. This system helps eliminate waste the body makes. This system works closely with other systems and cleans waste from the skeletal, muscular, digestive, respiratory, nervous and circulatory system.
* Reproductive System
The male reproductive system consists of two major parts: the testes and the penis. The female reproductive system has two major parts which are the vagina and the uterus. They are a collection of organs that work together for the purpose of creating life.
* Musculoskeletal System
The musculoskeletal system is controlled through the nervous system and consists of muscles, bones, cartilage, ligaments and tendons. The three main types of muscles are: smooth muscles, cardiac muscle and skeletal muscle. This system is responsible for the movement of the human body and also protects vital organs.
* Immune System
The immune system is the body’s defence against infection and illness. It is made up of a network of cells, tissues and organs. There are three main lines of defences: The skin, nonspecific responses and specific responses.
* Integumentary System
The Integumentary system consists of the skin, hair, nails, nerves, and assorted glands. This system protects the internal structure of the body, prevents dehydration, regulates body temperature and stores fat. It also assists to maintain homeostasis within the body.
* Endocrine System
The Endocrine system controls the way the body functions. It is made up of many glands that produce and release hormones. This system helps to regulate growth and development, metabolism and reproduction. The main endocrine glands are the pituitary, thyroid, parathyroid, adrenal, pancreas and gonads.

These systems interact together to ensure the body is functioning properly. When there is a problem with one system, it’s very possible that it will affect another system. It is
