This presentation includes all the parts of cardiovascular system with each detailed functions.

2. Circulatory System
•Responsible for
transporting materials
throughout the entire
body.

3. Circulatory System
• Transports nutrients, water
and oxygen.
• Heals and fights infections.
• Removes wastes.

4. Circulatory System
•Two divisions:
1. Cardiovascular System
2. Lymphatic System

5. Circulatory System
•Two divisions:
1. Cardiovascular - blood
2. Lymphatic - lymph

6. Cardiovascular System
•Transports nutrients,
gases, hormones, and
other materials to and
from the cells of the body.

7. Cardiovascular System
•Parts:
1. Heart
2. Blood Vessels
3. Blood

8. 1. Heart
•Muscular organ(strongest
muscle) that pumps blood
to the different parts of
the body.

9. Heart
• Structure:
1. Pericardium - sac
2. Pericardial Cavity – filled with fluid
3. Epicardium – outer layer
4. Myocardium – middle layer
5. Endocardium – inner layer

10. Heart
•Parts
1. Chambers
2. Valves
3. Blood Vessels

11. Chambers of the Heart
•Four: Right and Left
Atrium and Right and
Left Ventricle.

12. Chambers of the Heart
•Atria- receiving chambers
•Ventricle- pumping
chambers

13. Chambers of the Heart
• Right Atrium- receives
deoxygenated blood from vena
cava.
• Left Atrium- receives oxygenated
blood from pulmonary veins.

14. Chambers of the Heart
• Right Ventricle- pumps blood
deoxygenated blood from RA to
pulmonary artery to lungs for oxygenation
• Left Ventricle-pumps oxygenated blood
from LA to the aorta to all parts of the
body.

15. Blood Vessels in the Heart
• Aorta – largest artery. Conveys oxygen rich blood
from the LV to all parts of the body.
• Superior Vena Cava – conveys deoxygenated blood to
the RA.
• Pulmonary Artery – conveys deoxygenated blood
from RV to the lungs.
• Pulmonary Veins – Convey oxygenated blood back to
the LA.

16. Valves of the Heart
• Atrioventricular/cuspid valves –
between atria and ventricles.
• Semilunar Valves – located at the
bases of the heart’s blood vessels
and the ventricles.

17. Atrioventricular Valves of the Heart
• Tricuspid Valve – between right
atrium and right ventricle.
• Bicuspid Valve – between left atrium
and left ventricle.

18. Semilunar Valves of the Heart
• Pulmonic Valve – between right
ventricle and pulmonary artery.
• Aortic Valve – between left ventricle
and aorta.

19. 2. Blood Vessels
• Network of channels that convey
blood to all parts of the body.
• Three types: Artery, Vein and
Capillaries

20. 2. Blood Vessels - Artery
• Conveys oxygen rich blood away
from the heart.
• Arterioles – smallest arteries.
• Aorta – largest artery.
• Elastic

21. 2. Blood Vessels - Artery
• Parts
1. Tunica Externa
2. Tunica Media
3. Tunica Intima

23. 2. Blood Vessels - Vein
• Convey blood coming from the body
back to the heart.
• Venules – smallest veins.
• Vena Cava – largest vein.

24. 2. Blood Vessels - Vein
• Parts:
• Tunica adventitia/externa
• Tunica Media
• Tunica Intima/Interna

27. 2. Blood Vessels - Capillary
• Exchange of materials – gases,
nutrients and waste products of
metabolism.
• Connects arterioles and venules.
• Smallest and thinnest.

29. Pathways of Blood Circulation
• Pulmonary Circulation –
deoxygenated blood returns to the
heart.
• Systemic Circulation – oxygen-rich
blood is distributed to different parts
of the body.

30. 3. Blood
• Is a liquid tissue and the circulating
medium of the circulatory system.
• Portions:
1. Plasma – Liquid portion
2. Corpuscles – formed elements

31. 3. Blood - Corpuscles
• Erythrocytes – red blood cells
• Leukocytes – white blood cells
• Thrombocytes – platelets

33. 3. Blood - Erythrocytes
• Hemoglobin – makes it color red. An
iron-containing molecule that can
bind with oxygen.

34. 3. Blood - Leukocytes
• Defends the body against both
infectious diseases and foreign
materials.

35. 3. Blood - Thrombocytes
•For blood clotting.

36. 3. Blood Groups
•A, B, AB and O
Blood Type Antigens (RBC) Antibodies (Plasma)
A A Anti b
B B Anti a
AB A and B None
O None Anti a and b
