CARDIOVASCULAR SYSTEM
● Cardiovascular system consists of:
1. Heart
2. Arteries
3. Veins
4. Capillaries
● Function
1. Circulation of blood
a. Primary function
2. Delivery of O2 and other nutrients of the body Pericardium
a. If there will be problems in the ● Invaginated sac
cardiovascular system this may result to ● Protects the entire heart
problems in other system e.g. respi ○ Visceral
system ■ Attached to the exterior of myocardium
3. Removal of CO2 and other cellular products of ○ Parietal
metabolism ■ Attached to the great vessels and

ANATOMY OF THE HEART
Heart
● Muscular pumping organ that propels and receives blood from
the venous system of the body.
○ Muscle can be controlled through contractions →
pumping organ
● Hollow muscular organ that weighs 300 400 grams
● Resembles like a close fist
● Located in Papillary Muscle
○ Behind the sternum and between the lungs ● Arise from the endothelial and myocardial surface of the
■ Transcends to the left side (left lungs) ventricles and attached to the chordae tendineae.
○ On the middle of mediastinum
○ Chordae Tendineae
● Kaya merong 2 na hati ung heart
● Hair like structures that divide the left and right heart
● Attached to the TV and MV

BOARD QUESTION:
Answer: 2 chambers
Atria / Atrium
● 2 chambers
● Function : receiving chambers
● Upper chamber ––(connecting or receiving chamber)
● Location : lies above the ventricles
1. Right atrium
a. Receives systemic venous blood through SVC ,
IVC and coronary sinuses
b. Receives deoxygenated blood ● SVC & IVC → right atrium → tricuspid Valve → right
2. Left Atrium ventricle → left & right pulmonary artery → lungs → left &
