Path of blood through circulation

Question 1

Pressure Veins vs. arteries

Answer 1

-arteries direct blood away from heart through high pressure system

-veins direct blood back to the heart through low pressure system with one-way valves

Question 2

Systemic circulation

Answer 2

-left side of heart pumps oxygenated blood throughout the body delivering nutrients and gases to the tissues

Question 3

Pulmonary circulation

Answer 3

-right side of heart pumps de-oxygenated blood to the lungs for gas exchange with external environment

Question 4

Artery branching

Answer 4

-Aorta is largest artery and is first to leave the heart

-Arteries get smaller and smaller further you get from the heart, eventually becoming arterioles and then they connect to capillaries for material exchange

Question 5

Vein branching

Answer 5

-Venules sitting close to capillaries where exchange occurs and then they branch back to the heart getting larger and larger into veins, and eventually cranial and caudal vena cava which enters the heart

Question 6

First artery to branch from heart

Answer 6

Aorta, then coronary artery which supplies the heart

Question 7

Capillaries

Answer 7

-exchange materials with organs

Question 8

Cardiovascular circulation pumps

Answer 8

-basically 2 pumps acting in series
- Right= pulmonary circulation
Left= systemic circulation

Question 9

Blood flow movement

Answer 9

-flows from high pressure to low pressure (arteries higher than veins)
- pressure changes result in opening and closing of valves

Question 10

Blood distribution

Answer 10

-not equal throughout the system and will vary
- veins will hold most because they have ability to fill up

Question 11

Path of blood flow through circulation

Answer 11

1. Right ventricle
2. Pulmonary arteries
3. Lungs
4. Pulmonary veins
5. Left atria
6. Left ventricle
7. Aorta
8. Systemic arteries
9. Capillaries
10. Systemic veins
11. Vena cava
12. Right atria
