Blood And Circulation
Akopọ
Every second, the heart pushes blood through a closed network of vessels that reaches almost every cell in the body, carrying oxygen, nutrients, hormones, waste and the immune system's front line all at once, in the same fluid. This topic takes blood apart component by component, follows it through the exact chambers and vessels of the heart, and compares the three vessel types built to do very different jobs along the way.
You need precise structure-to-function reasoning here: why an artery is built the way it is, which vessel connects to which heart chamber, why the left ventricle is thicker than the right, and how ABO blood groups make transfusion a matter of matching antigens rather than simply topping up volume.
Awọn Afojusun
- Know the composition of the blood: red blood cells (erythrocytes), white blood cells (phagocytes and lymphocytes), platelets and plasma
- Understand the role of plasma in the transport of carbon dioxide, digested food, urea, hormones and heat energy
- Know the role of tissue fluid and explain how this arises as a result of pressure differences and its subsequent drainage into the lymphatic system
- Explain how red blood cells are adapted for oxygen transport
- Understand the role of ABO blood groups and their importance in blood transfusions
- Understand the role of white blood cells including phagocytosis and antibody production
- Describe the importance of blood clotting and the role of enzymes in causing the conversion of fibrinogen into fibrin
- Compare the structures of arteries, veins and capillaries, and understand their roles including the pulse
- Know the general plan of the circulatory system to include the blood vessels to and from the heart, the lungs, the liver and the kidneys
- Know the structure of the heart and how it functions
