Cardiovascular System Research Paper

The cardiovascular system, which consists of the heart and blood vessels, is the circulatory systems in our body. The major function of the system is transportation; the heart is the system pump and the blood vessels are the delivery routes. The heart transport respiratory gases, nutrients, wastes, and other substances vital to the body’s homeostasis to and from the cells by using the blood as a medium.

Blood is made up of straw coloured plasma, the matrix, in which various types of blood are carried. Plasma is mainly water where substances are carried such as oxygen and carbon dioxide, nutrients such as glucose and amino acids, salts, enzymes and hormones. Also there is a combination of important proteins which help with blood clotting, transport,

The cardiovascular system consists of the heart, blood vessels, and the approximately five liters of blood that the blood vessels transport. Responsible for transporting oxygen, nutrients, hormones, and cellular waste products throughout the body, the cardiovascular system is powered by the body’s hardest-working organ, also known as the heart, which is only about the size of a closed fist. Even when it is at rest, the average heart easily pumps over 5 liters of blood throughout the body every minute.18

Blood does many important processes in our organism, such as transporting oxygen from the lungs and nutrients to the tissues of the body, removes the waste products from the tissues, including carbon dioxide.

The heart consists of many major functions. It transports nutrients, gases and waste products. The cardiovascular system works linking all the parts of the body to some type of artery or vein. This allows non-stop movement to deliver and eject nutrients, gases and waste products through the body. It pumps 5 to 6 liters of blood per minute through your body and can pump as many as 30 liters per minute during times of extreme stress. The cardiovascular system works with the respiratory system to deliver oxygen to the tissues of the body and remove carbon dioxide. In order to do this effectively the cardiovascular system is divided into two circuits, known as the pulmonary circuit and the systemic circuit. The cardiovascular system also maintains

The cardiovascular system is a very complex system in that includes not only the main organ the heart, but also the arteries, veins, and capillaries as well, and even the liver. So, one questions a lot of people may ask is how does the heart work in order to keep us alive day in and day out. Well, that answer is quite simple the heart pumps blood through the superior and inferior vena cava and it then pumps to the lungs to pick up oxygen and then back out through the aorta to the rest of the body. However, if someone wants to know the details and complexity of the heart, it would be like this. So there are multiple chambers in the heart. The heart has four chambers an upper right and left that are called atria, while the lower right and

Your body contains about one and a half gallons of blood and accounts for 8% of your body weight. The blood flowing through our bodies is called whole blood, but can be separated into two parts: plasma and formed elements. The formed elements include platelets, white blood cells, and most importantly red blood cells. Untouched whole blood is five times thicker than water, has an average temperature of 100.4 degrees fahrenheit, and has a slightly alkaline pH level of 7.4.

The second portion of blood is made from solid components, both formed and fragmented cells. When bleeding occurs somewhere in the body, the solid components of the blood each have their own unique responses as well. These components are Red Blood Cells (RBCs), White Blood Cells (WBCs), and Platelets. RBCs are formed cells that hold the oxygen within the blood. These cells are made of a hollow membrane that can hold oxygen and is flexible enough to squeeze through small vessels like the capillaries. (Tortura 696). When blood loss is significant enough to disturb oxygen transfer to cells, the body attempts to compensate by mass producing in the skeletal tissue (Red Cross 159). Another formed cell is the WBCs or leukocytes that hold the primary function of preventing infection in the blood stream.

Blood is a substance found in organisms that play a role in the transportation of oxygen and nutrients through the organism to its muscles and organs (Unknown, 2017). Blood consists of red blood cells (RBC) which make up to 45% of the volume and transports oxygen, white blood cells that is used to protect the body from infections and then the rest consists of water, ions, platelets and nutrients that is regulated throughout the body (Campbell et al., 2008). The amount of heamogloban in organisms differ depending on gender with males tending to have more red blood cell than females (Merritt et al., 2014). Blood is divided into four types (A, B, AB, O) which depends on the antigen and Rh factor on the surface of the RBC (Campbell et al., 2008).

The blood is a very important fluid of our body that has many different ways that keep us healthy. It transports important nutrients and oxygen to our cells and acts in the process of removing wastes and carbon dioxide from the body.(“American Society of Hematology”. n.d.) Also, this specialized fluid helps in defending the body by forming blood clots as a result of a wounded blood vessel and carrying various cells that are crucial to our health. An average human body’s weight is made of seven to eight percent blood.(“American Society of Hematology”. n.d.) The blood is made of different components that perform different actions. It is made of 55 percent plasma and 45 percent cells. (“American Society of Hematology”. n.d.) The blood is liquidy due to the presence of plasma. It is composed of water, proteins, fats, and salts. The plasma is crucial in transporting the blood cells and bring waste products to be removed from the body to the kidney and liver. (“American Society of Hematology”. n.d.) The blood cells are main components of the blood and have distinct purposes. Red blood cells, also known as erythrocytes, are the

The cardiovascular system is an extremely complicated network of three main parts the blood, the heart and the blood vessels. Basically the job of the cardiovascular system can be explained in two parts, the first is to remove by products from tissues and the second is to deliver nutrients to the body. The heart is situated right in the very centre of the cardiovascular system, the heart summed up is simply a four chambered pump that dispenses blood to the arteries. The human body is made up of arteries and veins, the function of the arteries is just to bring nutrients and oxygenated blood to the heart and it is there where the cycle is consistently in a continuously circuit, the cycle happens thousands of times a single day.

Blood is “a complex, living tissue that contains many cell types and proteins” (green). The average adult body is comprised of more than five liters of blood (purple). Blood basically consists of four components, each with a specific function. Almost half of the blood volume is red blood cells, which transport oxygen and other nutrients to the organs and tissues, as well as remove carbon dioxide and other wastes. White blood cells, which are used to fight infections, and platelets, which form blood clots to prevent blood loss only make up about 1% of the total blood volume. The rest of the blood, about 55%, is plasma, the fluid that carries the blood cells, along

Coronary circulation is the circulation of blood in the blood vessels of the myocardium (heart muscle). Coronary arteries deliver oxygen-rich blood to the myocardium. Cardiac veins remove the deoxygenated blood from the myocardium.

The cardiovascular system consist of three organs the heart, blood vessels, and blood. They work together in order to provide oxygen throughout the whole body, the heart composed of cardiac muscle is the main organ in the human body without it we won’t be able to live it, its function is mostly to pump blood throughout the whole body. The blood vessels are composed mainly by smooth muscle throughout the whole body carrying blood such as the arteries and the veins, which takes carbon dioxide and other waste out of the body. There are two types of blood cells white and red blood cells. The white blood cells main function is to help maintain the body’s immune system, while the red blood cells are used for carrying

The cardiovascular system is comprised of the heart, blood and blood vessels its main function is to pump the blood around the body and get oxygenated blood to working muscles and deoxygenated blood to the lungs. The heart is a double pump which is split into two sides, the right side of the heart deals with deoxygenated blood while the left side of the heart deals with oxygenated blood. Bellow outlines the flow of blood around the heart.
