White Blood Cells
Everyone has a defense system in their body. They’re called white blood cells. White blood cells are a part of the Immune system and the Cardiovascular System. White blood cells have a structure that helps it function. But sometimes they can malfunction. Everybody needs white blood cells to stay healthy. White blood cells are a large part of the Immune system, and greatly contribute to the
Cardiovascular system. In the cardiovascular system, they act like highways that contain the heart, blood, and blood vessels. Their job is to carry waste products away from the cell, and also carries glucose which makes energy. Blood is used to carry oxygen to the lungs and to other parts of the body. “When Cells break down glucose,

The Nonspecific Immune System is where white blood cells come in. They make sure that no foreign pathogens enter the body.
These white blood cells migrate to fight that infected area. The Specific Immune System is made of T cells and B cells. Both kinds help produce bone marrow. “Memory cells give an animal immunity to future attacks by the original invader”(Padilla et al. 89). The Immune System and
The Cardiovascular System are both key for the white blood cells.
White blood cells are necessary for a human body to keep it healthy. Their job is to be like a superhero that fights off bad infections, diseases, and viruses by creating antibodies. White blood cell are also called leukocytes. They are larger than red blood cells and contain a nucleus and ribosomes. White blood cells are produced by marrow and contained in the veins or blood vessels. They only last about three days, but are only 1% of the human blood system, they are so important. These cells carry nutrients to the cell. They also keep a consistent blood temperature for warm-blooded animals. “There are about 4,000 to 11,000 white blood cells per cubic
Millimeter of the blood in the human body” (Manar). There are five different types of

This can cause a very serious health issue. Certain medicines can also raise or lower the amount of white blood cells that enter your body at a time and can, in worst cases, have heart issues. Myeloproliferative disorder is a disorder that can cause an unhealthy balance of the blood (of all kinds) cells. This disorder can trigger excessive amounts of immature blood cells which could cause serious health problems. One of a disease is Leukemia. In all, these malfunctions happen when the system of checks and balances
According to Virtual Medical Centre (2014) the primary function of the blood is to act as a transport, to give the body protection and to help regulate. The blood dissolves gases such as oxygen and carbon dioxide. The blood also transports vital nutrients throughout the body, such as micro-nutrients, fatty acids and amino acids. The flow of the blood helps to regulate the body’s temperature. Also the blood removes wastes material of metabolism. Blood cells (white and red cells) are carried through the body to help with the body’s natural defense, blood clotting and the carry anti-bodies.
The human immune system is an amazing system that is constantly on the alert protecting us from
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.
Most of the time nonspecific defenses keep pathogens from getting into the body. Sometimes one can break through and cause a disease. This is where the immune system comes into use.
The endothelium is a cell layer that is lined on the interior surface of lymphatic vessels and blood vessels, which are made up of endothelial cells (Dorland, 2012).

The structure and function of our immune systems is a great help for our body to keep all of us healthy. Our immune system has a specific structure that it should maintain. There are also organs that play a major part for the health of our immune system. These organs are called lymphoid organs because of the lymphocytes that inhabit that area. (white blood cells) Bone marrow is also one of the key elements for the immune system, this is where all of our blood cells are being made along with the white blood cells. With the help of the bone marrow, white blood cells are constantly traveling throughout our bodies using the blood cells for help. Another structure that is important for our immune system is lymphoid tissue. Lymphoid tissue acts as a gateway into our bodies that help to prevent incoming germs.
They have no nuclei or mitochondria in human cells, which means their small size can fit through very small capillaries. They are produced in the bone marrow (since they cannot reproduce as they have no DNA from mitochondria and nucleus). They contain hemoglobin, an iron-rich protein, which attracts oxygen. This makes it easy for red blood cells to obtain oxygen, and then transport it to the tissue in the body through the bloodstream. They also pull out carbon dioxide from the blood stream, and transport it to the lungs to be breathed out.
These cells are lymphocytes which means they are involved in specific immune responses to foreign matter; specifically in adaptive immunity (Joanne M. Willey, 2014). The hematopoietic stem cell branches off to the lymphoid progenitor (Joanne M. Willey, 2014) . That splits into lymphoblasts which make the agranulocytes, T and B cells (Joanne M. Willey, 2014).
A white blood cell, also known as macrophages, are effective in the way that they ingest the unknown pathogen and get rid of it right away (Delves, 2014). The adaptive immune system—which I will talk about later in more detail—will work much slower and will use a variety of lymphocytes and marked antibodies to recognize a particular pathogen, and eliminate it if it were ever to come in contact with it again. The innate immune system will also use several types of cells, with different functions, to get rid of the pathogen. A natural killer cell is an important part of the innate immune system. It specifically recognizes cancerous cells by “looking” at their surfaces. If it were to find a cancerous cell, the natural killer cell would use a poison to kill the cancerous cell (Institute for Quality and Efficiency in Health Care,
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 immune system defends the body against foreign invaders through a sequence of steps known as the immune response. A network of organs, cells and tissues must work together in order to protect the body. The immune response can be divided into innate immunity and adaptive immunity, though these divisions are artificial and the system functions as a single unit.
Our blood is able to connect all our organs together to create one organism and is able to transport the most vital and important molecules through these blood streams. Hence, blood cells are needed for immune system function and metabolic functions.
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
According to KenHub, the blood consists of cells, cell fragment and an aqueous solution(plasma).45% of blood are red blood cells, white blood cell and platelets and the rest are plasma which consists of water, plasma protein and
