Cardiovascular Lab 8
Experiment #8: Cardiovascular System: Heart Sounds, Palpitating, Pulse, Blood Pressure, Venous Pressure
Week #: 8 (Dry Lab)
DEFINITIONS:
1. SYSTOLE: CONTRACTION OF THE HEART CHAMBERS DURING WHICH BLOOD LEAVES THE CHAMBERS; USUALLY REFERS TO VENTRICULAR CONTRACTION
2. DIASTOLE: RELAXATION OF THE HEART CHAMBERS, DURING WHICH THEY FILL WITH BLOOD; USUALLY REFERS TO VENTRICULAR RELAXATION
3. CARDIAC CYCLE: COMPLETE ROUND OF CARDIAC SYSTOLE AND DIASTOLE
4. VENTRICULAR SYSTOLE: WHEN ARE THE AV VALVES CLOSED?
5. VENTRICULAR PRESSURE: EVENT WITHIN THE HEART CAUSES AV VALVES TO OPEN
6. SOUNDS OF KAROTKOFF: SOUNDS YOU LISTEN FOR WHEN TAKING BLOOD PRESSURE “LUB DUP”
7. PULSE PRESSURE: DIASTOLIC – SYSTOLIC PRESSURE
8. PULSE: HEART BEAT IN A MINUTE
9. BLOOD PRESSURE: THE PRESSURE OF BLOOD AGAINST THE WALLS OF ANY BLOOD VESSEL
10. PULSE DEFICIT: DIFFERENCE BETWEEN THE HEART RATE AND THE PALPABLE PULSE
Introduction:
Cardiovascular system means the system of heart and blood vessels of human body. The term “cardiovascular” is a combination of two word; “Cardio” and “vascular”. The term “cardio” is derived from “cardiac” meaning Heart and the term “vascular” means blood vessels. So the name itself indicates that cardiovascular systems is the system of heart and blood vessels. Cardiovascular system is also known as “Circulatory System”. Cardiovascular system is made up of three major components; Heart, Blood vessels and blood. The heart is a hollow muscular organ made of strong cardiac muscles. The heart can push the blood through the circulatory system with great force. In fact push of the heart is the major force that causes circulation of blood throughout human body. Heart is made up of three layers; Pericardium, Myocardium and Endocardium. Human beings, unlike other some other species, have a closed circulatory system which essentially means that blood does not come into direct contact with body tissues. Rather, the blood flows in restricted pathways
