Transcript of Circulatory System
Red Cells-carry oxygen to and from the heart.
White blood cells-help the body to fight infection and ailment.
Platelets-help to stop bleeding and create scabs.
Plasma-transports different nutrients, hormones, and proteins. Red Cells-carry oxygen to and from the heart. Blood Type A- you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma. Blood Type AB- you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma. Blood Type O-you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma. The Different Blood Types Are: Blood Type B- you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma. Some blood types can be put together and some cannot. Blood Type 'O' can donate red blood cells to anyone. It is an universal donor. Blood Type 'A' can donate red blood cells to A's and AB's Blood Type 'B' can donate red blood cells to B's and AB's Blood Type 'AB' can donate only to other AB's , but can receive from all others. Since Dexter and his family members are all in the same human body they are all the same blood type. The different types of blood are determined by
the presence or absence of certain antigens. Antigens are substances that can trigger an immune
response if they are foreign to the body. Since some antigens can trigger a person's immune system to
attack the transfused blood, safe blood transfusions is important. Not only are there A and B antigens, but there is another one that we call RH Factor. RH Factor can be either present (+) or absent ( – ). Rh-negative blood can be given to Rh-negative. Rh-positive humans can receive from both Rh-positive and Rh-negative humans. The heart is always related to the size of your fist because your heart and fist grow at the same rate. A blood transfusion is a relatively simple medical procedure during which a patient receives blood through an IV because either their blood doesn't have enough oxygen or to prevent fatigue. If Dexter and all the blood drops around him do not have enough oxygen and is supposed to be oxygenated, then the human may have to get a blood transfusion. A human's blood pressure is determined by two numbers,
systolic and diastolic pressure. Both the systolic and diastolic pressure measurements are important
– if either one is raised, it means you have high blood pressure (hypertension). The systolic pressure is the maximum pressure in an artery at the
moment when the heart is beating and pumping blood through the body. The diastolic pressure is the lowest pressure in an artery in the
moments between beats when the heart is resting. Systemic Circulation- Starts at the left ventricle and ends at the right atrium. Carries oxygenated blood to the rest of the body. Pulmonary circulation - carries blood between the heart and the lungs. It begins on the right ventricle and ends on the left atrium. Deoxygenated blood leaves the right ventricle by the pulmonary artery and is carried to the capillaries of the lungs. At the end of the day Dexter has gone through two different types of circulations, pulmonary and systemic. Works Cited
