The cardiovascular system - The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. It consists of the heart, which powers the whole process, the veins, arteries, and capillaries, which deliver oxygen to tissue at the cellular level. The cardiovascular system carries blood that is low in oxygen away from the heart to the lungs via arteries, where oxygen levels are restored through the air once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive. The cardiovascular system is the workhorse of the body, continuously moving to push blood to the cells. If this important system ceases its work, the body dies.
The cardiovascular system is divided into two systems a pulmonary and a systemic. Pulmonary division- blood flows from the heart to alveolar capillaries and back to the heart. Systemic division- blood flows from heart to every capillary “except alveolar” and back to heart.
The cardiovascular system has 3 main functions
• Transportation- The cardiovascular system transports blood to almost all of the body’s tissues.
• Protection- The cardiovascular system protects the body through its white blood cells. Platelets and red blood cells form scabs to seal wounds and prevent pathogens from entering the body and liquids from leaking out.
• Regulation- Blood vessels help maintain a stable body temperature by controlling the blood flow to the surface of the skin (Terfera, David, and Jegtvi)
Why do we need to exercise? With out exercise many of our bodies arteries in the cardiovascular system can become clogged and bring on much unwanted cardiovascular diseases. Exercising regularly helps us maintain a healthy weight if already fi...

An artery is an elastic blood vessel that transports blood away from the heart. There are two main types of arteries: pulmonary arteries and systemic arteries.
As the digestive system breaks down your food, after it's broken down it turns into energy. Your circulatory system takes some the produced energy and transports it around the body, delivering it and other blood, nutrients, oxygen, and more compounds to every cell in your body. The digestive depends on the circulatory as much as it does vice versa because they need the blood, nutrients, and energy (broken down food) that was produced from both systems. Many digestive organs need to use about 30% of cardiac output. Both the digestive and circulatory systems get rid of unwanted or unneeded materials (waste) and feces (poop). The vial substances are absorbed by the small intestine, where it is put into the bloodstream, so it can be circulated around the body. The most important thing is that with no nutrients and circulation, there's no life.
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
Staying healthy does not only mean to eat a healthy diet, but also to be active and to provide our body with stamina so it can fight various diseases. According to Myers (2003) around a quarter of a million deaths in the United States are caused by insufficient physical activity. The US Public Health Service (1996) has provided enough evidence towards the effect of physical exercise on cardiovascular (e.g. coronary heart disease) and non-cardiovascular health (hypertension, osteoporosis, colon cancer etc.). They followed a group of people for several years and found a positive correlation between the amount of participants’ physical activity and their health problems. So how much exercise is just enou...
The pattern of blood flow starts in the left atrium to right atrium, then into the left ventricle and right ventricle. During its course, blood flows through the mitral and tricuspid valves. Simultaneously, the right atrium is granted blood from the veins through the superior and inferior vena cava. The job of the superior vena cava is to transport de-oxygenated blood to the right atrium. When your heart beats, the first beat represents the AV valves closing to prevent the backflow of blood into the atrium.
The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...

The heart, blood and blood vessels make up the cardiovascular system. The function of the cardiovascular system is to evenly distribute blood cells, water and nutrients. The cardiovascular system helps send blood to the body’s tissues. The heart is a muscle and the most important part of the cardiovascular system. Heart attacks, heart failure, and abnormal heart beat is a serious issue for the cardiovascular system these can sometimes lead to death. These diseases affect the heart and its functions (Heart and Cardiovascular disease 2005).
Exercise is often thought of in a positive light. It is common belief in today’s society that a healthy diet and a regular exercise routine will lead to a long, healthy life. And in the simplest sense of the word, it will.
In nature there are two different types of circulatory systems that can be seen amongst different taxonomic groups. These two types are open and closed circulatory systems, and help animals to be able to survive within the environment. Each taxonomic group has a specific circulatory system so that it is best adapted for its environment. A open circulatory systems is a system where the blood of the organism and interstitial fluid mix in the organisms body (https://moodle.wnc.ac.uk/mod/resource/view.php?id=94728).
Lastly, blood is involved in maintaining homeostasis by negative feedback loops such as temperature regulation, blood pH, blood glucose levels, and blood pressure.
The roles of the circulatory and respiratory system both carry important responsibilities and are essential in their jobs to the human body. The circulatory system is one, if not the, most important system in the human body. The circulatory system is made up of the heart, blood, and blood vessels. Within the blood vessels, there are three types: arteries, veins, and capillaries. The heart is an organ made up of cardiac muscle that has a role similar to a pump. When the muscles in the heart contract, it pumps fresh blood away from the heart, through a main artery called the aorta, and to the organs and cells of the body. Nutrients and oxygen then enter the cells through diffusion of the tissues. The respiratory system transports oxygen to the circulatory system. When transporting oxygen to the circulatory system, this will in turn transport oxygen to the rest of the cells in the body. Aside from transporting oxygen to the body, the respiratory system also plays a role in the removal of carbon dioxide and other contaminants in the body. These two systems effectively and efficiently work together in order to supply the body with oxygen and remove carbon dioxide and any other
Adding exercises into one’s daily routines can change their whole lifestyle. Many people look at exercise as being something just for people who want to lose weight or to become muscle bound, but there are a great deal of benefits that can be received from exercising regularly. Of course gaining muscle and losing fat are the two most popular reasons that usually attract people to the gym, but they make up a small part of the potential benefits that can be achieved with exercise. There are several ways in which I have benefited in my life from exercising regularly, besides just making me bigger and stronger. It has made me become more organized, helped me make better decisions, and motivated me to take on new challenges in life.
