Human Circulatory System

Aims of the Assignment The aim of this project is to test the heart of multiple people with a series of experiments. I hope to learn what the effects of smoking are on the heart. I hope to achieve a clear answer on what stops a heart from being as healthy as it can be.

Background information Humans have a closed circulatory system in which the blood travels in a continuous system of blood vessels. The main parts of this circulatory system are the heart, blood, and blood vessels.
There are different types of blood vessels in the human body.
Arteries carry blood away from the heart and carry blood under high-pressure Veins carry blood towards the heart and carry blood under low pressure and have valves to prevent backflow. Capillaries connect arterioles to arteries, and capillaries also connect veins to venules. All these blood vessels are used by the heart to circulate blood around the body.

A healthy heart pumps blood more efficiently around the body. A healthy heart can be had through regular exercise and a balanced diet. Heart rate is a good indicator of a healthy heart. You can check your heart rate by checking your pulse. Pulse is the throbbing of the arteries. According to Edward R. Laskowski, " A normal resting heart rate for adults ranges from 60 to 100 beats a minute." The more athletic you are, it seems, though, the lower your resting heart rate, which also means a healthy heart.

Cardiomyopathy

Cardiomyopathy is a disease that affects the cardiac muscle. Cardiomyopathy makes the process of blood pumping around the body more difficult for the heart to do. There are different forms of cardiomyopathy: dilated, hypertrophic and restrictive. Hypertrophic is the most common affecting any age and all genders equally. It usually makes the ventricles and lower chambers of the heart thicken. Dilated usually makes the ventricles enlarge and then weaken, and restrictive usually makes the ventricles become step and restrict them. Cardiomyopathy, when left untreated, can lead to such problems as heart failure. Symptoms of this disease include swelling of the lower regions, including legs and ankles, tiredness/fatigue, and dizziness. Depending on the type of cardiomyopathy, the severity of the treatment ranges from medication to surgically implanted devi...
