What is Cardiovascular System ? Cardiovascular system, also referred as the circulatory system, is made up of the heart, blood and blood vessels that ensure nutrients and wastes are carried around the body. It is the transportation of oxygen, carbon dioxide and nutrients such as amino acids, electrolytes, to and from the cells in the body, in order to give nourishment and help in suppressing diseases. It also maintains the homeostasis and stabilizes the temperature and pH. What is Gas Exchange…
The cardiovascular, respiratory, sensory and endocrine systems play important roles in the functioning of the human body. The cardiovascular system involves the heart, blood and blood vessels, the respiratory system involves organs and structures, which allow the body to breath, the sensory system allows the body to receive external and internal information while the endocrine system involves the glands and secretes hormones throughout the body. The 4 systems to be discussed all work together to…
Cardiovascular disease, also known as CVD, is a killer that does not discriminate and affects people around the globe. “CVD is the most common cause of death worldwide, with 30% of all deaths attributed to the disease (World Health Organization (WHO) 2013” (Walker, 2013). Cardiovascular disease has a vast array of issues related to it as well as many risk factors; nevertheless, with positive behavioral changes many of these risk factors can be reduced, thus creating physiological changes. The…
Cardiovascular System The human body is made up of several systems that need to work together to function properly. These systems are essential for survival. The cardiovascular system is one of the most important systems in the human body. The main components of the cardiovascular system is the heart, the blood vessels, and the blood. What is Cardiovascular system? The cardiovascular system, which is also known as the circulatory system, consists of the heart and blood vessels that carry nutrients…
The Cardiovascular System The cardiovascular system is made up of the heart, blood vessels and the blood and its main functions include the transportation of blood around the body, protection from invading microorganisms and to prevent blood loss through haemostasis. (Widamaier, et al 2011:5) One of the main organs of the cardiovascular system is the heart; the heart is made up of four chambers. The blood enters the right atrium of the heart from body through the venae cavae, it then travels though…
two body systems, the cardiovascular system and the respiratory system in the relation to energy metabolism in the body. Energy metabolism is where energy is generated from nutrients and delivered to the organs around the body. Energy is needed in the body in order muscular movement, circulation of the blood, lymph and tissue fluid, breathing process, cell growth and repair, the transition of nerve impulses and for the building of different complex molecules. The cardiovascular system There are…
the cardiovascular system also called the circulatory system is the transportation system of the body a major structures that make this possible are the heart blood vessels and blood simply put the heart pumps the blood in order to move nutrients through the blood vessels to nourish and remove the metabolic wastes from the body the purpose of this video is to present a basic understanding of the cardiovascular system a more in-depth study of the system will be presented and other CT videos where…
Introduction The cardiovascular system is a fundamental system for survival, providing the body nutrients and removing waste via a network of arteries, arterioles, capillaries venous and veins. (Sherwood). Understanding this fundamental system is critical to help further understand even more complicated medical conditions such as Postural orthostatic tachycardia syndrome (POTS), inappropriate HR increase when standing (Freeman et al., 2011). In addition, the cardiovascular system also has other properties…
runs a race and finishes first. That individual is breathing harshly and if one could see internally, the heart is pumping blood rapidly as well. This is known as the Cardiovascular System. It contains not only the heart, but also the blood vessels, blood and much more which will be further explained in greater detail. The venous system takes blood back to the heart. It flows from the capillaries to the veins. The biggest vein in the body is the inferior vena cava. The superior cava carries blood from…
usually receive the proper amount of blood and oxygen needed to keep the body running. However, when the cardiovascular system fails, the tissues and organs in the body don’t receive and adequate amount of blood and oxygen it needs, this is called shock. Shock is when blood circulation decreases and eventually stops. Shock can be cardiovascular and non-cardiovascular. There are three main cardiovascular causes of shock, which are; poor pump function, blood or fluid loss from blood vessels and poor vessel…
