Catabolism is the set of metabolic pathways that breaks down molecules into smaller units to release energy. In catabolism, large molecules such as lipids, nucleic acids and proteins are broken down into smaller units such as fatty acids and amino acids. When food is broken down energy is released as the foods molecules’ bonds are broken. Then this energy is used to reform the bonds that have been broken so that ATP can be recreated. More energy can be obtained when oxygen is present and the process proceeds on aerobically. The aerobic production of ATP occurs inside the mitochondria in cells. The broken down food molecules then enters the blood stream. Blood is a liquid connective tissue as it is made up of red and white living cells. Oxygen is transported in the red blood cells which are attached to a protein called haemoglobin. Nutrients including glucose are dissolved in the plasma. Plasma is a mixture of water, sugar, fat, proteins and salts. The main function of the plasma is to transport blood cells throughout your body along with nutrients, waste products, antibodies, clotting proteins and chemical messengers such as hormones that help maintain the body’s fluid balance. The red blood cells also carry iron which attracts oxygen. Our cells use oxygen to make energy. Iron is also needed to keep the immune system healthy and help brain cells. Without your heart, blood vessels and blood you wouldn’t be able to get the

The body needs to circulate glucose and oxygen rich blood to the cells within the body and remove carbon dioxide waste from the muscle. This role is specifically dedicated to the cardiovascular system. The heart, veins, arteries and capillaries make up the cardiovascular system.

Blood contains nutrients from the foods you eat and oxygen from the air you breathe. It also

The central organ of the Cardiovascular System is the Heart, the muscular organ pumps blood through an intricate network of Blood Vessels to all parts of the body. The heart sends blood around the body. The blood provides the body with the oxygen and nutrients it needs. It also carries

The hearts function as a double pump that serves two circulations. The pulmonary pump in the right side of heart is provided for the gas exchange in the body, and the systemic circulation in the left side provides the functional blood supply to all body tissues. The functional blood to the heart is provided by the coronary arteries. Right coronary artery supplies the heart through the posterior interventricular and marginal artery branches; and the left coronary artery supplies the heart via anterior interventricular artery and the circumflex artery. The myocardium is drained by great, small, and middle cardiac veins which

The cardiovascular system consists of the heart, blood vessels and 5 liters of blood that the blood vessels transport. The cardiovascular system is transporting oxygen, nutrients, hormones and cellular waste products through the body. The cardiovascular system is powered by the hardest working organ the heart.

The Circulatory system is responsible for the transport of blood throughout the body. The Circulatory system has many organs. The main components are the heart, the blood, and the blood vessels. It also consists of arteries, arterioles,

Blood, or whole blood, consists of about 55% plasma and 45% formed elements; which include platelets, white blood cells and red blood cells or erythrocytes (Martini et al., 2015). Plasma consists of 90% water and serves to transport minerals throughout the blood, especially clotting platelets to the site of an injury in order to prevent loss of blood (Martini et al., 2015).

All of the four heart areas have an important blood vessel that goes in or out. The arteries go out of the ventricles and the veins go in the atria.

The heart pumps the blood around the body through the blood vessels which is made of mostly veins and capillaries. The blood carries the dissolved oxygen around the bodily

Blood has many functions and is a complex structure of cells and fluid. It helps fight bacteria, protect the body from infection, carry valuable sources of minerals and nutrients around the body, dispose of waste materials, keeps the body temperature regulated and helps with glandular distribution of hormones and enzymes.

There are three main types of blood vessels: arteries, veins, and capillaries. Arteries are vessels that usually carry highly oxygenated blood away from the heart and to the rest of the body. (The pulmonary trunk and related arteries are exceptions, as they actually carry blood from the lungs toward the heart.) Because arteries must transport high volumes of blood being forcefully pumped out by the heart and must therefore withstand greater pressure, most have thick, muscular walls and are more flexible as well. Arterioles, smaller types of arteries with thinner walls, branch off of the arteries to carry blood to another type of vessel, called the capillary. Capillaries are the most abundant blood vessels in the body. Thinner and smaller than the other blood vessels, the role of capillaries is to exchange substances like water, gases, chemicals, nutrients, wastes, etc. with the tissues of the body. The third type of blood vessel is the vein. Although they are generally larger than the other blood vessels, veins tend to have thinner, less flexible walls, as they are not forced to deal with such high blood pressures. Venules (veins’ versions of arteries’ arterioles) connect the capillaries to the veins, which then transport blood back

The cardiovascular system consist of the heart, also known as the circulatory system. The major organs in this system is the heart, blood,capillaries, veins and arteries. When I hear cardiovascular system I automatically think about life itself. We have to have the heart in order to survive. The heart is the major organ in the cardiovascular system, it pumps blood throughout the body to organs, tissue, and cells. Think of the heart as being the fuel pump on the car. The fuel pump has to pump the gas to the engine to keep that car running. Same thing with the heart the heart has to pump blood to our bodies in order for us to run. Then you have the blood it's job is to carry oxygen and nutrients to every cell in the body and to remove any waste

Each cell generally lasts for as little as a couple days to weeks. Also, plasma is a straw colored clear liquid that is 90% water and carries blood cells through the body. It contains dissolved salts and minerals such as calcium, sodium, magnesium, and potassium. Also, it carries microbe-fighting antibodies to the disease in the body. Without plasma, blood cells would not be transported and therefore would not provide the body with nutrients and oxygen. Finally, When the body loses excessive amounts of blood, blood platelets along with mineral calcium, vitamin K, and fibrinogen form clots or “scabs” to stop the bleeding. Without these minerals and nutrients, it will take longer for the body to form a clot, causing you to bleed to death. A healthy diet can provide these required nutrients.
