Cardiovascular System

Function Cardiovascular system or

Circulatory System Maintains the distribution of

blood throughout the bod Delivery of substances to the

cells of the body and the removal of wastes

Composed of two parts: Pulmonary circulation: transports

deoxygenated blood from the right side of the heart to the lungs—oxygen and carbon dioxide are exchanged—oxygenated blood is carried back to the left side of the heart

Systematic circulation: transports oxygenated blood from the left side of the heart to cells of the body and back to the right side of the heart

Cardiovascular System Organs

Composed of:

Heart: organ that contracts to pump blood through

blood vessels

Blood Vessels: closed system of tubes that

conducts blood throughout the body; consists of

arteries, veins, and capillaries

Veins: blood vessels of cardiovascular systems that carry

blood toward the heat

Arteries: blood vessels that carry blood away from the

heart

Capillaries: smallest blood or lymphatic vessels; blood

capillaries are very thin to allow gas, nutrients, and waste

exchange between blood and tissues

3 Important Cardiovascular

Procedures

1. Echocardiography

2. Pacemaker Implantation

3. Stent

Echocardiography (ECHO) Diagnostic method

Noninvasive

Takes 15-30 minutes

Ultrasound used to visualize & evaluate internal cardiac structures and cardiac valve activity

Used to detect abnormal anatomy or infections of the heart valves

Provides information on the size & shape of the heart & its pumping strength

One of the most widely used diagnostic tests for heart disease

ECHO Video

Pacemaker Implantation

Pacemaker: sinoatrial node of the heart—where

electrical impulses begin

Pacemaker Implantation: electrical device that

substitutes for the natural pacemaker of the heart

Controls beating of the heart by series of rhythmic

electrical impulses

Can be internal, or external

Internal: electrodes surgically implanted the chest wall

External: electrodes on the outside of the body

Pacemaker Video

Stent A stainless steel tube placed within blood vessels or

ducts to widen lumen

Lumen: space, cavity, or channel within a tube or tubular organ or structure in the body

Placement:

A small opening in a blood vessel is made

A catheter with a deflated balloon at its tip is used to place the collapsed stent

An x-ray is taken of the tube as it's threaded through the blood vessels

A dye is injected to help show narrow or blocked areas in the artery

The balloon is inflated widening the artery and helping to restore flow

The fully extended balloon expands the stent, pushing it into place

The balloon is deflated and pulled out along with the

Stent (…continued)
