Transcript of Circulatory System

Circulatry system By Victoria D'angelo, Amaris Arias, Ashley Macias, Sarah Pisarsky The human circulatory system is responsible for delivering food, oxygen, and other needed substances to all the cells in all parts of the body while taking away waste products. The basic componets of the system is the heart, the blood vessels, and the blood. Artery An artery is a vessel that brings blood away from the heart. It brings all of the important nutrients and oxegen to the rest of your body. Vein A vein is a vessel that transports blood to the heart. The veins have valves that open with every beat so your blood doesn't just fall back to your feet. The heart is about the size of a clenched fist and weighs about 10.5 ounces (300 grams). A heart beats about 100,000 times a day, close to 2.5 billion times a lifetime. 1.) Did you know that blood plays a very important part in the circulartory system? It circulates around you body carrying oxygen and nutrients to all the cells of the body. 2.) Certain proteins on the surface of red blood cells cause people to have different blood types. You can have A, B, AB, or O type blood. The heart is an Involuntary musle, which means we don't control it. The heart is made up of 4 chambers, the upper parts are called the Atria(s) and the lower chambers are called the Ventricle(s).The right ventricle recives deoxygenized blood from the body sending it to the right atria which sends it to the lungs to pick up more oxygen.The left Atria recives Oxygen-rich blood and sends it to the left ventricle which pumps the blood through the whole body. Red Blood Cells Read blood cells' job is to carry oxygen to all the parts of the body. These cells cirulate 100-120 times a day. White Blood Cells White blood cells are part of the immune system, helping defend the body. These cells live up to 3-4 days. Digestive System This system breaks down the nutrients needed for all of the body parts to live. The Circulatory system is also known as the
Cardio Vascular System from the greek word "Kardia", meaning the heart. Also from the Latin word "Vasculum" meaning small vessel. A vein is a vessel that transports blood to the heart. The veins have valves that open with every beat so your blood doesn't just fall back to your feet. Vein Red blood cells Vocabulary What is the Circulatory system? The Heart 4.) Each day 2,000 gallons of blood travel many times through about 60,000 miles of blood vessels. 3.) The left ventricle is sronger than the right ventricle because the blood it carries is full of oxygen. Four Fun Facts Platelets are irregularly shaped cell fragments. Having too little of them can cause bleeding, too many of them can cause blood clots and other serious problems in the body. The average life of a platelet is 5-9 days. Platelets Blood Cells Muscular systems The circulatory system sends the needed nutrients, energy, and oxygen to the musles. Respertory System This system provides oxygen to the circulatory system so it can feed the rest of the body. Supporting Body Systems Nervous System This sends info to your brain about blood pressure. The brain maintains blood pressure and heart rate.
