Blood Vessels
Akopọ
Blood travels around your body through three kinds of vessel, each built for a different part of the journey: thick muscular arteries that withstand high pressure, thin-walled capillaries where exchange happens, and wide veins with valves that return blood gently to the heart.
In this lesson you will learn the structure of arteries, veins and capillaries and where the main vessels are found. Extended students will explain how each vessel's structure fits the pressure it carries and the job it does, and meet the special vessels that serve the liver.
Awọn Afojusun
- Describe the structure of arteries, veins and capillaries, limited to: relative thickness of wall, diameter of the lumen and the presence of valves in veins
- State the functions of capillaries
- Identify in diagrams and images the main blood vessels to and from the: (a) heart, limited to: vena cava, aorta, pulmonary artery and pulmonary vein (b) lungs, limited to: pulmonary artery and pulmonary vein (c) kidney, limited to: renal artery and renal vein
- [Supplement] Explain how the structure of arteries and veins is related to the pressure of the blood that they transport
- [Supplement] Explain how the structure of capillaries is related to their functions
- [Supplement] Identify, in diagrams and images, the main blood vessels to and from the liver as: hepatic artery, hepatic veins and hepatic portal vein
