Circulatory System

Circulatory System

By: Tomas Cortes

Where is it and What does it Do? It’s located Throughout the whole body It is called the Body’s Transportation System aswell as the

cardiovascular systemThe systems is responsible for the flow of:

OxygenCO2Other gasesHormonesWaste products Nutrients

Main Organs-HeartThe HEART– It is the Pump that makes it all

workIt has four chambers or sections:

two atria andtwo ventricles These sections are made out of cardiac muscle.

The heart is split in two halves: Right Side - Receives blood full of CO2 from

the body and Sends it to the lungs. Left Side – Receives Oxygenated blood from

the lungs and Sends it to the body

Heart picture

Blood VesselsArteries: Take blood away from the heart. They have very

thick walls so that they can take all the power that is produced by the heart.

Veins: Take the blood back to the heart. Don’t have thick walls, thin walls and more space for blood to flow.

Capillaries: Tiny blood vessels that are as thin as a hair or thinner. Capillaries connect arteries to veins. Nutrients, Oxygen, Co2 and other wastes go in and out though the thin walls.

BloodBlood contains four major things:

Erythrocytes (red blood cells)Leukocytes (white blood cells)Platelets (it is what stops you from bleeding to death

from a paper cut, it helps your blood clot or dry up.)Blood plasma (it is what the rest of the components of

blood lie on) Did you know that one drop of blood has around 50 million red blood cells, 100,000 white blood cells, 2.5 million platelets yet the biggest component of blood is the blood plasma.

Different Types of Circulation There are three types of circulation:

Coronary circulation: It’s the circulation inside the heart. It brings in nutrients and lets out waste.

Pulmonary Circulation: The circulation in between the blood and lungs. Red blood cells drop of Co2 and pick up O2 to take to the heart.

Systemic circulation: It’s the circulation that goes all over you body.

Did you know that in pulmonary circulation the oxygenated blood goes in veins to the heart and blood cells that don’t have oxygen travel in arteries to the lungs. In the other types of circulation arteries carry the oxygenated blood and veins carry the oxygen lacking blood.

Diseases-Blood PressureThe pressure that heart provides for the

blood to go out to the lungs and body and to come back. There are two types of pressure measured:Systolic (the higher number) is the pressure

created when the heart contracts (sends blood to lungs and body) – Under 120 is considered healthy

Diastolic (lower number) is the pressure when the heart relaxes and the blood flows back into the heart from the body and lungs

Systolic and Diastolic Pressure

How to Keep it HealthyEat nutritiously

Healthy snacksVery little Fast FoodDo not become obeseSome Fats and oils are very unhealthy – learn

which ones.Do exercise regularly

Exercise more watch TV lessDo NOT smokeTry to keep a low stress level

Relationship with other SystemsThe circulatory system is related with three other systems.

The inmune system because inside blood there are white blood cells and platelets. They belong to the inmune system now that platlets try not to let infections in though your blood and white blood cells fight the germs and bacteria that manage to get into you system.

The urinary system because before blood goes back to the heart capillaries drop of solid waste in the kidneys to get peed out

The respiratory system because it drops of O2 at cells so that they can do cellular respiration in the mitochondrias and pick up Co2 that is produced after the mitochondiras burn up sugar to create energy and in the process let out Co2.
