CIRCULATORY SYSTEM
Definition
It is a fluid-filled network of tubes (or vessels) through which materials move between the environment and the cells of a multicellular animal.
Characteristics
•It connects all parts of an organism in a way that allows individual cells to thrive as well as for organisms to function as a unit.
It is an entirely closed system.
CIRCULATORY SYSTEM
CIRCULATORY SYSTEM
Remove waste materials from cells Carbon dioxide urea
Function
Transport materials needed by cells Oxygen Glucose
CIRCULATORY SYSTEM-HEARTHEART
Heart is just a pump. It has:
- 2 atria - 2 ventricles
It is made of their own special muscle called cardiac muscle.
CIRCULATORY SYSTEM
Its interwoven muscle fibers enable the heart to contract, or squeeze togheter, automatically.
CIRCULATORY SYSTEM
CIRCULATORY SYSTEM
Blood travels from right atrium through a valve, to the right ventricle. From there, it is pumped to the lungs to pick up oxygen.
CIRCULATORY SYSTEM
From the lungs, the oxygen-rich blood goes to the left atrium and then to the left ventricle to get pumped around the body.
Blood Vessels
Blood vessels are of three basics types: arteries, veins and capillaries.
Arteries carry blood away from the heart.
CIRCULATORY SYSTEM
Veins bring blood from the body to the heart.
CIRCULATORY SYSTEM
Capillaries are enabling to exchange water and chemicals between the blood and the tissues.
CIRCULATORY SYSTEM
Blood is composed of a yellowish liquid called plasma, which are millions of solid cells in suspension.
CIRCULATORY SYSTEM-BLOODBLOOD
CIRCULATORY SYSTEM
• Plasma is an yellowish river of water and minerals in which all blood cells flow.
CIRCULATORY SYSTEM
• Red blood cells pick up oxygen (H2O) in the lungs, deliver it to all the other cells in the body.
CIRCULATORY SYSTEM
• Red blood cells carry away carbon dioxide waste (CO2).
CIRCULATORY SYSTEM
• White blood cells flight against infections. They surround germs, kill them, and carry away the dead cells.
CIRCULATORY SYSTEM
• Platelets are brownish-yellow bits of cells that helping form blood clots.
CIRCULATORY SYSTEM
• Fibrinogen are fibers weave around platelets at a cut or injury to plug up the flow of blood and form a scab.
CIRCULATORY SYSTEM
• A colorized scanning electron micrograph of a blood clot formed in vitro.
CIRCULATORY SYSTEM
• Antibodies latch onto germs so white blood cells can find and destroy them.
Red Blood CellsRed Blood Cells
All of cells need oxygen to live. The red blood cells carry oxygen through the bloodstream and deliver it to others cells.
CIRCULATORY SYSTEM
A chemical called hemoglobin helps the red blood cells hold onto oxygen. One of the main ingredients of hemoglobin is iron.
CIRCULATORY SYSTEM
If your body does not get enough iron in the foods you eat or the vitamins you take, you can develope iron deficiency anemia.
Hemophilia
What is Hemophilia?
Hemophilia is a rare bleeding disorder that causes excessive bleeding and easy bruising.
It can take a long time for your blood to clot after an injury or accident.
What causes Hemophilia?
The hemophilia gene passes on birth.
The factor VIII or IX gene changed only in the baby’s body. One in three babies has no family history of hemophilia.
How is Hemophilia diagnosed?
Do a physical exam, and order blood tests.
How is Hemophilia treated?
To injecte the low or missing clotting factors directly into the bloodstream. This is called replacement therapy.
Replacement therapy
Whether you have a bleeding problem,Whether it’s due to hemophilia or another cause
How to treat Hemophilia with first aid?
Apply first aid as soon as possible to limit the amount of bleeding and damage. Do this even if factor replacement will also be given.
