Human cardiovascular system, organ system that conveys blood through vessels to and from all parts of the body, carrying nutrients and oxygen to tissues and removing carbon dioxide and other wastes it is a closed tubular system in which the blood is propelled by a muscular heart two circuits, the pulmonary and the. Your heart sits in the middle of your chest and pumps blood from about 4 weeks after conception until the day that you die this little pump is the size of your clenched fist and it never stops watch these videos to learn more about how the heart works, blood flow in arteries and veins, blood pressure, and lymphatics. Cardiovascular system anatomy & physiology the heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body it is a four-chamber pump, with the right side receiving deoxygenated blood from the body at low presure and pumping it to the lungs (the. Cardiovascular physiology is the study of the circulatory system, specifically addressing the physiology of the heart (cardio) and blood vessels (vascular) these subjects are sometimes addressed separately, under the names cardiac physiology and circulatory physiology although the different aspects of cardiovascular.
Cardiac veins: those veins that branch out and drain blood from the myocardial capillaries to join the coronary sinus carotid sinuses: enlargements near the base of the carotid arteries that contain baroreceptors and help to control blood pressure anatomy and physiology of the cardiovascular system chapter 5.

The cardiovascular system, also known as the circulatory system is a topic in anatomy and physiology it was last tested in 2015 and is expected to return for the 2019 season. It is initiated by the contraction of the ventricles of the heart ventricular contraction ejects blood into the major arteries, resulting in flow from regions of higher pressure to regions of lower pressure, as blood encounters smaller arteries and arterioles, then capillaries, then the venules and veins of the venous system.
The cardiovascular system consists of the heart, which is an anatomical pump, with its intricate conduits (arteries, veins, and capillaries) that traverse the whole human body carrying blood the blood contains oxygen, nutrients, wastes, and immune and other functional cells that help provide for homeostasis. The human anatomy and physiology course is designed to introduce students pursuing careers in the allied health field to the anatomy and physiology of the human body. The heart itself is made up of 4 chambers, 2 atria and 2 ventricles de- oxygenated blood returns to the right side of the heart via the venous circulation it is pumped into the right ventricle and then to the lungs where carbon dioxide is released and oxygen is absorbed the oxygenated blood then travels back to the left side of. The heart is the transport system pump the delivery routes are the blood vessels using blood as the transport medium, the heart propels oxygen, nutrient, w.
