Hormones can react to increase blood pressure when it becomes low‚ the sympathetic division of the autonomic nervous system uses several ways to temporarily increase blood pressure when it has dropped for example during the fight or flight response. During the response‚ the sympathetic division is needed to stimulate the adrenal glands to release the hormones epinephrine and norepineprine which stimulate the heart to beat faster and for blood to flow more forcefully‚ this effect makes most of the

There are many different circulation routes throughout our bodies that help our body stay functioning right. One of these major circulation routes is the fetal circulation route. The fetal circulation route is the route in which the blood flows from mother to fetus. It often uses the entire fetoplacential circulation which includes the umbilical cord‚ and the vessels within the placenta that carries the fetal blood. Basically the placenta is doing the work that the baby’s lungs will do after it is

Smooth muscle- are involuntary muscles found in the walls of hollow organs like the stomach‚ intestines or bladder. Smooth Muscles have many functions in the body‚ but one of the functions of smooth muscles in the bladder contracts to push urine out of the body. Skeletal muscle- Skeletal Muscles are muscles attached to the skeleton. The skeletal muscles main function is to contract to support the skeleton in movement. Skeletal muscles are voluntary because we have complete control of the movements

The Capillary Bed The capillary bed is found in the superficial dermis and is an important part of the integumentary system. It is made up of a group of capillaries which are supplied with oxygenated blood via the arterioles and drained of deoxygenated blood via the venules of the circulatory system. The pulsating flow within the capillary bed is called vasomotion. The type of circulation through the capillaries is called microcirculation. Image 1 bellow shows the components of the capillary bed

cells which are adapted to enable them to carry out specific functions. Muscle cells and epithelial cells are two examples of specialised cells within the body that are adapted for specific functions. Multicellular organisms such as mammals‚ the cardiovascular system is the main transport system. This particular system is powered by the heart and relies on the blood in order to transport substances such as oxygen and carbon dioxide around the body through a network of blood vessels including the veins

2. Compare the development of lymphocytes with other formed elements. B lymphocytes develop in red bone marrow‚ T lymphocytes develop in red bone marrow and mature in the thymus; the other formed elements develop in red bone marrow 3. What is erythropoiesis? Which factors speed up and slow down erythropoiesis? Erythropoiesis is the process by which red blood cells (erythrocytes) are produced. If you lose a lot of blood‚ erythropoiesis will speed up; anemia can cause erythropoiesis to slow down

“ Ageing is a continuous‚ complex‚ and dynamic process that begins with birth and ends with death. And unless we die in our early years‚ each of us will grow old and experience the effects of the ageing process”. (Pirkl‚ 2009). The ageing process and why changes have taken place in the last fifty years. This report discusses the ageing process and why changes have taken place in the last fifty years. The ageing process is a change in an organism overtime and can be referred to as a multidimensional
