How Does the Cardiovascular System Work? Cardiovascular System The cardiovascular system includes blood, blood vessels and the heart performing well-known roles necessary to life. As blood flows through the body, it carries oxygen, hormones and enzymes to the cells and transports carbon dioxide and other wastes for removal from the body. Blood also prevents fluid loss through clotting and fights infection. Cardiac Cycle * The heart is a muscle that pumps blood throughout the body.
The air we breathe in that is held in the lungs is transferred through the blood and the heart is involved with blood circulation where oxygenated blood is pumped from the lungs to the rest of the body. These two systems also work together to remove metabolic waste such as carbon dioxide. The heart is the main site these two systems work together. The heart consists of 2 atria and 2 ventricles. The right ventricle and atrium are responsible for receiving blood from veins.
P4: The Cardiovascular system The cardiovascular system refers to the heart, blood vessels and the systematic circulation (blood). Blood contains oxygen and other nutrients which your body needs to survive. The body takes these essential nutrients from the blood. At the same time, the body dumps waste products like carbon dioxide, back into the blood, so they can be removed. The main function of the cardiovascular system is therefore to maintain blood flow to all parts of the body, to allow it to survive.
The capillaries are part of the cardiovascular system. The oxygen binds with the haemoglobin, which is a red pigment located in the red blood cells. The oxygen is transported to the pulmonary veins and oxygenated blood is pumped to the left side of the heart. From the left ventricle, the oxygenated blood is pumped through the aorta, travels to smaller arteries until it reaches the capillaries. The oxygen from the oxygenated blood moves out from the capillaries and travels to the cells of the body.
The major cell type found in blood is red blood cells, whose role is to transport oxygen and carbon dioxide into and out of the body. The circulatory system also plays a secondary role as one of the routes immune cells use for transport around the body. Blood contains many types of what are called white blood cells, which are made up of mainly neutrophils, but also monocytes, T-lymphocytes and B-lymphocytes. Human blood is made up of two different components known as, cells and fluid. The cellular portion of blood includes red blood cells, white blood cells, and platelets.
Body (2-5 main points) I. Supply and Demand Step A. The need for blood is in demand. 1. Blood is always in demand according to American Blood Center; 4.5 million people in America will need a blood transfusion.

The cardio respiratory system consists of the lungs, heart, blood vessels, and the blood. In short, the cardio respiratory system is responsible for the uptake of oxygen from the air we breathe, for the transport of oxygen around the body, and for the removal of waste products from muscles and other organs. The beneficial changes within the circulatory system from exercise include making the heart stronger, providing more oxygen throughout the body for improved functioning and helping people to react better to stress while gaining physical benefits (long term effect). The musculoskeletal system is the part of the body composed of muscles, tendons, ligaments and bones. Basically it is everything needed for your body to actually move and is the basis for body mechanics.
One of the physiological process consist of cardiac system which performs the important task of rhythmic pumping of blood throughout the body to facilitate the delivery of nutrients, it also performs the pumping of blood through the pulmonary system for oxygenation of the blood. Most physiological processes are manifest themselves as signals that reflect their nature and activities.
Capillaries or small blood vessels surround the alveoli, and the blood picks up oxygen from the inhaled air. These capillaries also allow the blood to release its carbon dioxide, which is exhaled. The breathing process is made by the diaphragm, which is a strong muscle under the lungs. During inhalation, the diaphragm and rib cage expand the chest cavity, causing the lungs to suck in fresh oxygen. During exhalation the diaphragm relaxes and the muscle of the rib cage, are allowing the lungs to release air.
