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
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.
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.
Sepia apama copulation occurs by the male transferring sperm packets, called spermatangia, to a pouch located below the beak of the female that are internal sperm-storing organs called receptacles (M. Naud et. al. 2005). During this process of copulation, the female, which is polyandrous, displays patterns of dark blotches on their pale bodies (M. Naud et. al.
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.
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.
They contract to squeeze deoxygenated blood out of the heart, via the pulmonary artery, and then relax to allow the oxygenated blood to fill the heart, via the pulmonary veins then go to the whole body. This process is repeated constantly throughout your life and is responsible for circulating blood around the body however, the timing of an individual’s heart stimulation is different for everybody and is determined by specific cells known as the pacemaker cells in the heart. Skeletal muscle is a voluntary muscle as
Many of the internal organs of the body are protected by a membrane called the mesothelium. This membrane actually consists of two layers of cells. The inner layer surrounds the organs, and the second is a sac surrounding the inner layer. When organs within this membrane must move, expand or contract -- such as the heart, lungs, bladder, and so on, they are able to do so because the mesothelium produces a lubricating fluid between the two layers. Mesothelioma most often begins in the pleura or peritoneum.
Explain the relationship between the hepatic artery, hepatic vein, and hepatic portal vein. Include how these blood supplies influence the vascularization of the lobule (which is the functional unit of the liver). 6. Explain what a portal triad is. Follow the output of bilirubin (which is hemoglobin waste) through the liver lobule and portal triad.
The lymphatic vessels are present wherever there are blood vessels and transport excess fluid to the end vessels without the assistance of any "pumping" action. There are more than 100 tiny, oval structures (called lymph nodes). These are mainly in the neck, groin and armpits, but are scattered all along the lymph vessels. They act as barriers to infection by filtering out and destroying toxins and germs. The largest body of lymphoid tissue in the human body is the spleen.
