Your Body

The body is divided up into a number of systems.

As well as the Nervous system , Endocrine system, etc.LETS LOOK AT SOME OF THESE SYSTEMSThe Human Body

Skeletal System

Digestive System

Muscular System

Cardiovascular & Respiratory System

Digestive System• Without this

system, the body would not be able to obtain energy and nutrients.

• It breaks down all the food stuffed in my mouth into usable nutrients and expel the wastes.

Digestive System

Digestion begins when you first smell, see or think about a tasty food. Saliva begins to form in your mouth.When you eat the food your saliva begins to break down the food as you chew it.Once the food is swallowed it goes down the esophagus (say: ih-sah-fuh-gus) where the muscles in the esophagus push the food down into the stomach.

Digestive System

Attached to the end of the esophagus is the stomach. It is like a bag. In the stomach, food is mixed up into a pulp.From the stomach food goes into the small intestine. This starts at the end of the stomach. It is the longest part. Here, the nutrients from the food pass into the blood.

Digestive SystemAfter most of the nutrients are removed from the food mixture, there is waste left over. The large intestine pushes the waste into the rectum (say: rek-tum), the very last stop on the digestive tract. Then you flush the toilet.

Respiratory System

What is the Respiratory System?

The respiratory system takes oxygen from the air into our body.

Respiratory System Oxygen enters our body through our nose and mouth. Then, it goes down the trachea.The trachea is a tube which takes oxygen to our lungs

Respiratory System

The trachea is divided into two small tubes. These are called bronchi. Each bronchi is divided into smaller tubes. These are called bronchioles. The bronchioles are inside the lungs

Respiratory System

The lungs are two organs. They are like bags. They are inside the thorax or chest. Inside the lungs, oxygen goes into the blood

Respiratory System- Breathing

Nasal Cavity

Nose

Mouth

Bronchus

Bronchiole

Alveolus

Diaphragm

Throat

(pharynx)

Windpipe (Trachea)

Left lungs

Ribs

Blood circulationWhat is the circulatory system?

The circulatory system moves blood around our body.The circulatory system consists of the blood, the heart and blood vessels.The heart is an organ made of muscle. It is inside the thorax

Blood circulationBlood flows through the heart.

Then, it is pumped around our body. The heart’s pumping action is called heartbeat.

Blood circulates through blood vessels:

Veins are the vessels which carry the blood to the heart.

Arteries are the vessels which carry blood from the heart to the rest of the body

Blood circulation

The circulatory system transports blood around our body.Blood does three important things:

1.It collects nutrients from the small intestine, and transport them around the body.

2.It collects oxygen from the lungs, and transport it around the body.

3.It collects waste from the body, and transport it to the kidneys.

Excretory system

The excretory system cleans blood.

The most important organs in the excretory system are the kidneys.

They collect impurities from the blood. Then, they get rid of them in the urine. Urine collects in the bladder. It is expelled when we go to the toilet.
