Cardiovascular System.
The cardiovascular system, also known as the circulatory system; is made up of the Heart, Arteries, Veins and Capillaries. The cardiovascular system is responsible for the transportation of blood around the body. This particular system is powered by the main organ, the heart.
The cardiovascular system is responsible for the movement of blood, hormones, oxygen and nutrients around the body.
The heart is a pump which is constantly moving blood around the body. It is the main organ which keeps us alive.
The circulatory system works closely with the respiratory and the endocrine system.
The circulatory system the responsible for the passing of hormones around the body form the endocrine system. This system works with the respiratory system because as it is supplying the body with oxygen and nutrients.

The Digestive System.
The digestive system is responsible for the breaking down of foods and absorbing the nutrients from the foods.
When you eat the body uses the system to digest the food and use the cells from the food to make energy to be stored into the body.
The digestive system uses food to provide our bodies with energy, minerals and vitamins. This system is made up of many organs such as; liver; stomach; the small intestine and the large intestine.
This system helps us break down food we eat to enable our bodies to absorb the energy from the foods. When we swallow our food it is pushed down into the stomach where it is broken down and churned by the stomach acids, it is then pushed into the small intestine where the remaining food is then moved into the large intestine ready to be removed from the body.
The Respiratory System.

The respiratory system delivers oxygen around the body through the movement of the blood. This is done by our breathing.
The respiratory system consists of the lungs; nose; mouth; trachea; bronchus and larynx.
This system is responsible for the movement of oxygen around our bodies.
However there are many factors that can affect the respiratory system; such as infections; genetics and irritants that can affect our abilities to breathe.
Respiration is the term used to describe the process of breathing in (inhalation) air into our lungs and breathing the air out (exhalation) of our lungs.

The Renal System.

The renal system is also known as the urinary system.
The main organs for this system are the kidneys; uterus; bladder and urethra.
This system works to maintain the balance of chemicals in the body. It also controls how much water is in your body.
The Kidneys filter toxins from the body into urine. From the kidneys, urine travels down two thin tubes, called ureters, to the bladder where there you are able to release the urine.

The Nervous System

The nervous system is made up of the brain; spinal cord and nerves.
The nervous system sends messages from nerve responses to the brain which will allow us to do voluntary and involuntary movements.
This system is responsible for us being able to feel pain and pleasure. It is responsible for all over our movements. The central nervous system is one of the main systems in the body as is controls most of the body.

The Endocrine system
The endocrine system is responsible for the release of hormones and the glands. This system transfers the hormones around the body which sends information to different cells telling them what to do.
Many different hormones circulate through the blood stream however only some are programmed to receive and respond to messages.
Males and females have different hormones which each do different jobs within the body.
Hormone levels can be affected by stress and infection.

The Male Reproductive System.
The male reproductive system is completely different to the female reproductive system as the sex organs are located outside of the pelvis.
The male reproductive system is made up…
