Lecture 7 - Design of the vascular system (tbc)

Question 1

What are the two ‘juxtaposed’ systems that make up the circulatory system?

Answer 1

Systemic circulation
Pulmonary circulation

Question 2

Describe the systemic circulation

Answer 2

The systemic circulation sends oxygenated blood from the heart and returns deoxygenated blood back.
Blood vessels exit in parallel circuits
Route that blood takes:
* Left ventricle to……
* aorta to…..
* arteries to……
* arterioles to ……..
capillaries to…..
* venules to…….
* veins to ……
* vena cava to …..
* right atrium and ventricle.

Question 3

Describe the pulmonary circulation

Answer 3

The pulmonary circulation sends deoxygenated blood to the lungs from the heart for reoxygenation. Once reoxygenated the blood is sent back to the heart
Series circuit
Route that blood takes:
* Right ventricle to……
* pulmonary artery to…..
* arterioles to……
capillaries to…..
* venules to…….
* pulmonary vein to ……
* left atrium and ventricle

Question 4

What is the basic structure of blood vessels?

Answer 4

Majority of the blood vessel are made up of (from internal-external) endothelium, elastic tissue, smooth muscle, and fibrous tissue.
Structure varies due to function

Question 5

What layer remains constant in all blood vessels?

Answer 5

Endothelial layer
