Circulatory Problems, Wounds and Bleeding
Circulatory System The blood circulatory system consists of:-
The heart, which acts as a pump The blood vessels through which the blood circulates.
![Page 4: Circulatory Problems, Wounds and Bleeding Module 4.](https://reader030.fdocuments.us/reader030/viewer/2022032722/56649ce35503460f949aefbb/html5/thumbnails/4.jpg)

Circulatory Problems, Wounds and Bleeding
How The Heart Works? The cardiovascular system, composed of the
heart and blood vessels, is responsible for circulating blood throughout your body to supply the body with oxygen and nutrients.
![Page 5: Circulatory Problems, Wounds and Bleeding Module 4.](https://reader030.fdocuments.us/reader030/viewer/2022032722/56649ce35503460f949aefbb/html5/thumbnails/5.jpg)

Circulatory Problems, Wounds and Bleeding The heart is the muscle that pumps blood filled with
oxygen and nutrients through the blood vessels to the body tissues. It is made up of: Four chambers (two atria and two ventricles) that receive
blood from the body and pump out blood to it. The atria receive blood coming back to the heart. The ventricles pump the blood out of the heart.
Blood vessels, which compose a network of arteries, and veins that carry blood throughout the body. Arteries transport blood from the heart to the body tissues. Veins carry blood back to the heart.
Four valves to prevent backward flow of blood. Each valve has flaps that allow the forward flow of blood and prevent the backward flow.
An electrical system of the heart controls how fast it beats.

Circulatory Problems, Wounds and Bleeding
Types of Blood Vessels and It’s Functions Artery – transport oxygenated blood from the
heart. Vein – transport deoxygenated blood from the
tissue to the heart. Capillary – enable the exchange of molecules
between blood and interstitial fluid

Pattern of Blood Flow in bleeding. Artery
blood spurt out under pressure. bright red in colour,
Vein blood flow describe as a fast moving stream. dark red in colour.
Capillary blood oozes out

Circulatory Problems
What is Heart Attack?1. Cause by reduction of blood supply to the heart.
2. When heart cells are deprived of oxygen and blood, they begin to die, affecting the ability of the heart to pump.
3. Reduction of blood supply caused by blockages due to dislodged blood clots and narrowing of blood vessels due to fat deposits ( too much cholesterol in the bloodstream )
4. When the narrowed artery becomes completely blocked by a blood clot, a heart attack can occur.

responsiveness Remain with the casualty until help arrives.

Shock Shock is a life-threatening condition that occurs
when the body is not getting enough blood flow. This can damage multiple organs. Shock requires IMMEDIATE medical treatment and can get worse very rapidly
![Page 15: Circulatory Problems, Wounds and Bleeding Module 4.](https://reader030.fdocuments.us/reader030/viewer/2022032722/56649ce35503460f949aefbb/html5/thumbnails/15.jpg)

Treatment Bleeding - Apply direct pressure on both side of the
exposed hook. Three methods to prevent hook from penetrating deeper. Place two gauze pads or similar material on either side of
the exposed hook. Ensure gauze pads are level with the top of the hook
Bandage lightly over the pads and the hook.
