علوم للصف الخامس لغات درس الجهاز الدوري .

It consists of:
1- The heart 2- Blood 3- Blood vessels
The function of the circulatory system:
1- Transport the digested food, oxygen and water to all body cells
2- Transports what is formed inside a cell to special organs in the body to get rid of it
3- Helps to maintaining the body healthy
The heart:
Heart consists of four rooms (chambers):
1- Right atrium 2- Right ventricle
3- Left atrium 4- Left ventricle
Full of blood and connected with blood vessels
Heart has two sides:
1-The right-hand side 2- the left-hand side
The wall separating them
What of the function of the wall?
It prevents mixing blood found in both sides
The right side consists of:
A room called the right atrium at the top and the right ventricle at the bottom
The left side consists of:
A room called the left atrium at the top and the left ventricle at the bottom
There is a valve between each atrium and ventricle
What is the function of the 2 valves?
It allows blood to pass from atrium to ventricle and prevent it from returning back
The blood vessels
The blood vessels is a network of paths for the blood to flow.
There are 3 types of blood vessels:
Blood vessels
Veins
Blood capillaries
Arteries Made by :Mohamed Hatem
1- Arteries:
They
are blood vessels which emerge from the heart. They transport the blood
from the heart (the 2 ventricles) to the organs of the body. They are
wide at the beginning but it becomes narrower as it reaches the blood
capillaries near the cells. All the arteries contain oxygen-rich blood
except the pulmonary artery which contains plenty of carbon – di –
oxide.
2- Veins:
They
are blood vessels that carry blood from body organs to the heart and
opens in 2 atria (pl:atrium). They start in the form of capillaries near
the cells and combine together and become larger as they reach the
heart. All the veins contain carbon dioxide except pulmonary vein which
contains plenty of oxygen.
3- Blood capillaries:
The blood
The human blood consists of:
Blood
White blood cells (WBC's)
Plasma
Blood platelets
Red blood cells (RBC's)
Red blood cells:
1-These are red cell without nucle i
2-They function to carry oxygen from the lungs to all body cell
3-They carry carbon dioxide from the cells to the lungs
White blood cells:
1- These are white cells with nuclei of different forms
2-They function to defend the body against microbes Made by :Mohamed Hatem
Blood platelets:
They are small-sized cell fragments
They function to coagulate blood(forming blood clot)
They
prevent bleeding and infection of the human body when the body is
wounded and the blood is exposed to the air Made by :Mohamed Hatem
The path of blood through your heart (blood circulation)
What is meant by blood circulation?
The path of blood through the body is known as the blood circulation
1- The heart is a hollow muscular organ that pumps blood continuously
2- The heart is divided into 4 chambers
A) The two atria receives blood from the body parts through veins
B) The two ventricles pumps blood to all body parts through the arteries
3- The right atrium receives blood rich with carbon dioxide through the superior and inferior vena cava
4- The blood then reaches the right ventricle which contract and pump blood out to the lungs through the pulmonary arteries
5- The blood rich with carbon dioxide reaches the lungs and exchange carbon dioxide with oxygen
6- The blood rich with oxygen reaches the left atrium through the pulmonary veins

7- The left ventricle contract and pumps blood rich with oxygen to all body parts through the aorta artery Note: The right ventricle pumps blood to lungs at the same time that the left ventricle pumps blood to all body parts.
