In every drop of blood, there are 5 million red blood cells, also known as an enthrocyte. The red blood cell is part of the heart and circulatory system. Everything inside it is connected to how it works. Although the red blood cell is a great cell, it can malfunction and cause diseases. The red blood cell is a very interesting cell.
The red blood cell is part of the heart and circulatory system. Heart and blood vessels, including things like arteries, veins, and capillaries, make up the circulatory system. Our bodies have two circulatory systems, the pulmonary system and the systemic system. The pulmonary system goes from the heart to the lungs, then it comes back again. The systemic system sends blood throughout the body. The heart is a big part of the circulatory system. It’s main function is to propel blood throughout the body. The heart goes faster when needed, like when you are running or you are scared, but it can also go slower, like when you’re sleeping. The bottom of the heart is split into two parts called the right and left ventricles. They pump blood out of the heart. The upper part is made of the right and left atria. They take blood coming in through the heart. The arteries carry the blood away from the heart. Arterial walls have three layers. The endothelium is on the inside and it provides smoothness

Sometimes your red blood cell count can get low. This can cause many kinds of sicknesses and diseases. One of them is lung disease, which can happen when you do not get enough air from your red blood cells in your lungs. There is also anemia, which is when your body does not get enough iron. Red blood cells contain hemoglobin, which is an iron containing protein that binds with oxygen to make red blood cells red. I got all of my information for this paragraph from "High Red Blood Cell Count." MayoClinic, www.mayoclinic.org/symptoms
Red blood cells deliver the oxygen to the muscles and organs of the body.
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 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.
Anaemia, which is a low level of oxygen in the blood due to a lack of red blood cells or lack of haemoglobin heart failure, which means your heart is having problem pumping enough blood around your body, usually because the heart muscle has become too weak or stiff to work properly a problem with your heart rate or rhythm, such as atrial fibrillation.
In the body, bodily systems work hand in hand with one another to perform key functions. The circulatory system is a major system of the body, it comprises of the heart and three types of blood vessels know as the capillaries, veins and arteries. The heart is a muscular pump which has the duty of pumping blood so it is carried to the blood vessels, until it reaches the chambers in the heart. These capillaries carry oxygenated blood via the bloodstream so that organ tissues recive oxygen. The capillaries will take in any excess amount of carbon dioxide; this is carried to veins so the blood can be transported back into the heart and then the lungs.
There are many causes of anemia in the body. Some factors include genetics and deficiencies in the diet. Ms. A claims that for the past 10 – 12 years menorrhagia and dysmenorrheal have been a problem for her. Menorrhagia is abnormal and heavy menstrual bleeding during menstruation (Mayoclinic, 2013). Menorrhagia can deplete iron levels in the blood and increase the risk of an individual to have iron deficiency anemia. This is the cause of Ms. A’s anemia. Moreover, Ms. A says that she constantly takes aspirin especially in the summer to prevent stiffness in the joints. Aspirin affects and hinders the production of red blood cells (Mayoclinic, 2013). From the description of anemia given above, the lack of red blood cells, leads to low levels of iron and therefore low levels of hemoglobin which in turn affects the transportation of oxygen and thereby causing shortness of breath. Ms. A’s initial complains of shortness of breath and fatigue is the reason why she went to see the physician.
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...
As blood travels through the circulatory system, it is first pumped from the right side of the heart to the lungs through the pulmonary arteries and then separates into arterioles which split into capillaries. Here, the deoxygenated blood receives oxygen diffused in the lungs due to large surface area and travel back through venules and then pulmonary veins to the left side of the heart. From here, the oxygen rich blood is pumped throughout the body in arteries, arterioles, and capillaries, providing the body and cells with nutrients through osmosis. Afterwards, the now deoxygenated blood travels back to the right side of the heart containing deoxygenated blood, through venules and vein to repeat the cycle over again. Also, the heart is nourished by coronary circulation through the Right and Left Main Coronary Arteries.
Throughout Chapter 39, you are introduced into the major concepts of the circulatory system, the lymphatic system, the heart and how blood flows through it, and the respiratory system as well as the path of airflow through the respiratory system. In Section 1, you are introduced to arteries, capillaries, and veins as well as what consists of blood plasma. You are also introduced to the different blood cells and cell fragments such as red blood cells, white blood cells and platelets. In Section 2, you are introduced to both the pulmonary circulation loop as well as the systemic circulation loop. You are also introduced to how blood flows through the heart, as well as how contractions take place throughout the heart. Lastly, in this section you
According to our text book our arteries carries blood from our heart to our organs and muscles in our body. The heart pumps the blood and the pressure from the contraction of valves opening and closing pushes the blood with force. The veins are like tiny storage area to supply blood through out the body that is pumped from the heart. The veins are used to get blood specimens and injections.
The Respiratory System 1. Define respiration. Respiration is the process of converting glucose to energy, which goes to every cell in the body. 2. Describe the organs of external respiration.
Iron is a mineral that is found the in hemoglobin of the Red Blood Cells. It facilitates in the transport of oxygen all over the body. Without this mineral, oxygen cannot be carried to its full capacity. 1 out of 10 women and small children have iron deficiencies. Lacking iron causes lethargy and a weakened immune system. Children who do not have an adequate intake of iron put themselves at risk for intellectual developmental problems. However, an iron deficient person is not necessarily anemic. 7.8 million women are iron deficient, while only 3.3 million women are anemic (http://www.mayohealth.org/mayo/9704/iron_def.htm). When the deficiency becomes so severe that the circulating Red Blood Count and the minerals Ht, Hg, and Hem drop below normal, anemia occurs (See Figure 1). The hormone androgen causes men and women to have different normal values of the hemogram (http://www.medstudents.com.br/hemat/hemat4.htm). Low ferritin (iron storage molecule) and high TIBC (tota...
The circulatory system is a system of organs that pump blood, using your heart. The right and left side of your heart are two different pumps but they both move blood through your body. Erythrocytes are carried through a liquid in the blood called plasma. Other cells are also carries through the blood like leukocytes and thrombocytes. Although red blood cell are 99 percent of all the blood cells in blood. Each average adult has 20-30 trillion red blood cells in their body, those who live in higher altitude tend to have more erythrocytes than those living in lower altitudes, the reason why people living in higher altitude have more erythrocytes is, because in higher altitudes air is thinner, so you need more
Thalassemia is a blood disorder transferred through families. It occurs when the body makes less hemoglobin than needed or an unusual form of hemoglobin. Hemoglobin is the protein in red blood cells that carry oxygen. The disorder makes an excessive amount of destruction of red blood cells. This eventually leads to anemia.
Red Blood Cells contain hemoglobin molecules to help bind to oxygen to bring to other tissues. Without this function, cells would not be able to go through the process of cellular respiration and can only survive a short time. Red Blood Cells are also able to carry bicarbonate as a waste product and carry a variety of hormones to communicate between organs.
