Circulatory System
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.
The Heart
The heart is two sided and has four chambers and is mostly made up of muscle. The heart’s muscles are different from other muscles in the body because the heart’s muscles cannot become tired, so the muscle is always expanding and contacting. The heart usually beats between 60 and 100 beats per minute. In the right side of the heart, there is low pressure and its job is to send red blood cells. Blood enters the right heart through a chamber which is called right atrium. The right atrium is another word for entry room. Since the atrium is located above the right ventricle, a mixture of gravity and a squeeze pushes tricuspid valve into the right ventricle. The tricuspid is made up of three things that allow blood to travel from top to bottom in the heart but closes to prevent the blood from backing up in the right atrium.
The Aorta and the Arterial System
The arteries that take the blood to the head are found in something called aortic arch. After the blood goes through the arch, it’s distributed to the rest of the body. From the aorta, blood is sent to other arteries, where it gives oxygen to every cell.
The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make
Red blood cells deliver the oxygen to the muscles and organs of the body.
Haven't you ever wondered what would happen if you didn't have a digestive or circulatory system? Well, basically you wouldn't be able to be reading this or even be alive. While there are many important systems in the body, the circulatory and digestive are the two most important. There are many ways that they are similar, different, and how they work together.
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.
In this discussion post we are to describe the structures and functions of the respiratory system. We were asked to include major organs and how they work within the body and to notate symptoms of failure within the respiratory system.
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...
from the lungs and pumps it through the arteries to the various parts of the
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.
...In a drop of blood the size of a pine head there are about 5 million red blood cells, 10,000 white blood cells and 250,000 platelets. There are many organs that help with circulation. This is the process of how blood circulates through the body. 1. Blood enters the heart on the right side. 2. The right ventricle pumps blood to the lungs. 3. The lungs remove carbon dioxide from the blood. 4. The blood takes up oxygen and returns to the left side of the heart. 5. The left ventricle pumps the blood to the bod through the arteries. 6. The blood flows through the small intestine to pick up food water and medicine. 7. The blood flows through the live. This removes wastes and releases stored nutrients. 8. Capillaries deliver food, water, and medicine to the cells. They remove wastes and carbon dioxide. 9. The blood travels to the kidneys. These filter out more wastes and ex
It is about the size of a person's fist. The heart has four chambers. The upper two chambers are the right artium and left atrium, and the lower two are the right ventricle and left ventricle. Blood is pumped through the chambers, aided by four heart valves. The valves open and close to let the blood flow in only one direction.
The heart is a pump with four chambers made of their own special muscle called cardiac muscle. Its interwoven muscle fibers enable the heart to contract or squeeze together automatically (Colombo 7). It’s about the same size of a fist and weighs some where around two hundred fifty to three hundred fifty grams (Marieb 432). The size of the heart depends on a person’s height and size. The heart wall is enclosed in three layers: superficial epicardium, middle epicardium, and deep epicardium. It is then enclosed in a double-walled sac called the Pericardium. The terms Systole and Diastole refer respectively and literally to the contraction and relaxation periods of heart activity (Marieb 432). While the doctor is taking a patient’s blood pressure, he listens for the contractions and relaxations of the heart. He also listens for them to make sure that they are going in a single rhythm, to make sure that there are no arrhythmias or complications. The heart muscle does not depend on the nervous system. If the nervous s...
The respiratory system is made up of the organs and tissues in your body that help you breathe. The goal of breathing is to deliver oxygen to the body and take away carbon dioxide, a waste product that can be deadly if allowed to accumulate. The cells of the human body require a constant stream of oxygen to stay alive. The body needs oxygen to provide energy and growth to body cells. The respiratory system resides in the upper abdomen and chest area where the oxygen comes in through the nose, through inhalation, and is processed by the lungs. After air leaves the head it travels down through the trachea. It divides into two branches, the left and right bronchus, that enters into the lungs. There it goes into a thin membrane lining the walls of the lungs called the alveoli. “As a result, oxygen diffuses across microthin membranes into the blood from the alveoli and carbon dioxide diffuses into the alveoli from the blood” (Petechuk, 2004, pg. 20). So when you inhale, oxygen goes into the blood, and when you exhale carbon dioxide comes out of the blood.
The human body is very complex. It is like a job. You have to do a million things in one day to make it through the day. The body uses nine systems to do all of those jobs. They all have separate functions, but some work together. Each system is also made up of organs. There are many ways to care and protect the systems from the many different problems they can have. There are also many interesting facts about each system.
The three main types of blood vessels; artery begin with the aorta, the large artery leaving the heart, they carry oxygen rich blood away from the heart to all of the body tissues. They branch several times becoming smaller and smaller as they carry blood further from the heart. Capillaries are small, thin blood vessels that connect the arteries and veins. Veins these are blood vessels that take oxygen poor in blood back to the heart. The veins become large and large as they get closer to the heart. The superior vena cava is the large vein that brings blood from the head and arms to the heart and the inferior vena cava brings blood from the abdomen and legs into the heart. James (1999) stated that this vast system of blood vessels; arteries, veins and capillaries is over 60000 miles long. That’s long enough to go around the world more than twice. Blood flows continuously through your body’s blood
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.
