Module 1.2 Blood Vessels
1.2.a. Functional anatomy of arteries
In this topic we will learn the main characteristics of arteries and investigate the histological structure of arteries. We will look at the different types of arteries found in the body, and we will look at the different abnormalities that may develop in arteries. We will also learn the names of the major arteries in the body.
Learning Outcomes
- Identify the major arteries in the body
- Describe the structure and function of all types of blood vessels in the CVS
- Describe the microscopic structure of blood vessels
- Describe the mechanisms involved in the control of blood vessel diameter
- Describe the risk factors for coronary artery disease (CAD) and why they increase the risk of atherosclerosis
- Describe the basic steps involved in the progression of atherosclerosis

Concept Check
Now is the time to ask yourself what can you recall about the following terms:
- Arteries: blood vessels carrying oxygenated blood to the tissues.
- Conducting/Elastic arteries
- Distributing arteries
- Arterioles
1.2.b. Functional anatomy of capillaries
In this topic we will look at capillaries, their structure and function and where (in which organs) the different types of capillaries are found.

Learning Outcomes
- Describe different types of capillaries.
- Describe the main characteristics of the different types of capillaries.
- Identify the organs in which the different types of capillaries are found.
- Describe how blood flow through capillaries is controlled/regulated.
Concept Check
Now is the time to ask yourself what can you recall about the following terms:
- Continuous capillaries: tightly packed endothelial cells with intercellular clefts. relatively impermeable capillaries.
- Fenestrated capillaries: have fenestrations and are more permeable than continuous capillaries.
- Sinusoidal capillaries: large gaps between endothelial cells and are very permeable capillaries.
1.2.c. Functional anatomy of veins
In this topic we look at the structure and function of veins and abnormalities and clinical conditions that may arise in these vessels.
Learning Outcomes
- Describe the structure of veins and how they differ from arteries.
- Discuss their primary functions.
- Describe the hepatic portal system and its functional significance.
- Describe the 3 mechanisms in veins that promote venous return to the heart.
- The causes and consequences of DVT and varicose veins.
Concept Check
Now is the time to ask yourself what can you recall about the following terms:
- Capacitance vessels: Vessels that can store as blood storage vessels
- DVT: A condition where a blood clot (embolis) forms in a vein, dislodges and moves to the blood vessels in the lungs.
- Varicose veins: veins that become bulbous and convoluted due to failure of the valves in veins and ballooning of the walls of the vein.
Learning experience
Types of capillaries
Deep vein trombosis (DVT) and how an embolus can compromise blood perfusion of the lungs.
