From the lungs, blood drains into the left atrium and is then pumped into the left ventricle. The left ventricle then pumps this oxygen-rich blood out into the aorta which then distributes it to the rest of the body through other arteries. The heart is a hollow, muscular organ; its job is to pump blood through a network of blood vessels. The vessels form a circle, which starts at the heart, goes out through the body, then ends back at the heart again. The heart has two sides, the right and the left side.
Cardiac Cycle * The heart is a muscle that pumps blood throughout the body. Of course, the process is not quite that simple. The heart has four chambers, two on the right (right atrium and right ventricle) and two on the left (left atrium and left ventricle). The right side is responsible for accepting blood from the body and getting it to the lungs. The lungs add oxygen to the blood and remove carbon dioxide.
The blood vessels are a intricate network of tubes that transport blood throughout the body. These vessels carry blood from the heart via the arteries ,then arterioles, then to capillaries or sinusoids, to venules, to veins and back to the heart. The final component to this structure is blood that delivers nutrients and removes wastes that are a by product of cellular processes that happen within the body. What is its
Pharmacology: Celebrex Yiu Wing Man, Vanessa (13000332) Celebrex: A powerful painkiller Osteoarthritis is a chronic condition where breaking down the cartilage,causing stiffness, pain and loss of the joint movement. Celebrex (Celecoxib) is non-steroidal anti-inflammatory drug (NSAID) which is prescribed to treat inflammation and pain. It is most typically used for treatment of acute pain and osteoarthritis to relief the symptoms and signs. People chose Celebrex rather than others for the same purpose because of its better ability to protect stomach from serious complications. Some people have done clinical trials to find out the efficacy of Celebrex.
Lupus, what is it and how it affects you. Systemic Lupus Erythematosus often abbreviated to SLE or lupus is a chronic autoimmune connective tissue disease that can affect any part of the body. As occurs in other autoimmune diseases, the immune system attacks the body’s cells and tissue, resulting in inflammation and tissue damage. SLE most often harms the heart, joints, skin, lungs, blood vessels, liver, kidneys, and nervous system. The course of the disease is unpredictable, with periods of illness (called flares) alternating with remissions.
Cardio vascular and respiratory system Describe the structure and function of the cardiovascular system (P5) Blood vessels Arteries and arterioles | The arteries and arterioles carry the blood away from the heart (always oxygenate apart from the pulmonary artery which goes to the lungs). They have thicker muscular walls, and have smaller passageways for blood (internal lumen) they contain blood under high pressure. | | capillaries | Capillaries are found in the muscles and lungs. It is microscopic – one cell thick. Very low blood pressure.
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 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.
Also traveling through the arteries is fresh blood, which brings oxygen and other nutrients to all parts of the body, including your breasts. They’re distributed throughout the body. The Cervical lymph nodes are located in the head and neck. The Axillary lymph nodes are in the underarm area, divided into two types, superficial and deep lymph nodes. Supraclavicular lymph nodes are along the clavicle and collarbone.
1. A) Describe the cellular and the non-cellular components of human blood and how they move around the body. The circulatory system is responsible for the transport of blood throughout the body and consists of the heart (a pump), the lungs (a gas exchanger) and the vascular system of arteries, capillaries and veins (plumbing). Blood, which runs through this vascular system, contains both cellular and non-cellular components. 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.
