Circulatory system

The circulatory system is composed of vessels that take blood from the heart, thin-walled capillaries where exchange occurs, and vessels that return blood to the heart. Blood is pumped by the heart simultaneously into two ways the pulmonary and systemic circuits. The pulmonary system takes blood through the lungs where gas exchange occurs and the systemic system transports blood to all parts of the body where exchange with tissue fluid takes place. In practical terms, we can think of the systemic circuit as a means to conduct blood to and away from the capillaries, because only here does exchange with tissue fluid take place. Nutrient molecules leave the capillaries to be taken up by the cells, and waste molecules given off by the cells are received by the capillaries to be transported away. Capillaries abound in all parts of the body, and no cell is more than a few micrometers from a capillary. Blood is composed of two parts: formed elements and plasma. All of the formed elements contribute to homeostasis, as outlined in table 1. Oxygen is utilized during cellular respiration, a process that…

The circulatory system is the system that transports nutrients, oxygen, carbon dioxide, hormone. It also helps fight disease, maintain body temperature, pH, and homeostasis. There are two systems that make up the circulatory system which are the cardiovascular system and the lymphatic system. The circulatory system moves blood through the body and is made up of the heart, blood vessels and the blood. The lymphatic system moves lymph to various parts of the body and is formed by the lymph, lymph…

The Circulatory system, figures 15.2, 15.3 and terminologies Explain the circulatory system and its component in detail: The circulatory system helps to fight against diseases, and helps the body maintain a normal body temperature, and provides the right chemical balance to provide the body’s homeostasis, or state of balance among all its systems. Main Circulatory System Organs The circulatory system consists of the heart, blood vessels, blood and the lungs: Figure 1: circulatory system 1.…

The Cardiovascular system also known as the Circulatory System is an organ system that transports oxygen, nutrients, hormones and cellular waste products and permits blood to circulate and form cells in the body to nourish it with every heartbeat throughout the body.However, the Cardiovascular system is composed of the following organs, heart and blood vessels, including arteries, veins, and capillaries. One of the major structures of this system is the heart which functions to propel blood…

The heart is a complex organ that we need in order to pump blood to our body. The cardiac cycle and blood pressure (BP) are two things that greatly affect how our body can function. Both are a part of the circulatory system. There are many diseases that can affect the cardiac cycle and the BP. These diseases can affect our circulatory system, lungs, and our heart’s ability to function properly. When the cardiac cycle and BP are affected then the body is in danger of being greatly damaged. The…

11.2 The Circulatory System The circulatory system is made up of multiple different organs, and it's main function is transportation. The system allows blood to circulate, which transports oxygen, hormones and nutrients as well as picking up waste. The elements of the system include; The Heart The heart acts as a muscular pump which is divided into 4 different chambers, the heart's main function is to pump the blood around the body. It pumps deoxygenated blood through the veins, to the…

THE AMAZING CIRCULATORY SYSTEM The circulatory system preforms many different jobs. It carries oxygen to the cells of the body and it also caries nutrients throughout the body to make heat and energy. In addition to that, the vascular system delivers hormones to specific organs. Another thing the circulatory system does is collect metabolic waste and deliver it to the excretory glands. Lastly, the circulatory system works with the immune system to help fight infection and defend. The fact that…

parts are bodily systems that play a specific role within each and every human being. In these systems there are specific organs that carry out the the jobs of the respective system. The systems that are included in the physical makeup of a human include the circulatory, immune, skeletal, excretory, muscular, endocrine, digestive, nervous and respiratory. These systems have major similarities that are shared between each system, while also having major differences that separate these systems,…

The human body is composed of eleven major systems that all work together to hold a stable internal environment: homeostasis. Each system consists of different organs that all play important roles in maintaining homeostasis. The circulatory, respiratory and renal systems greatly affect each other in the keeping of the internal environment. Homeostasis is defined as the tendency of an organism or a cell to regulate its internal conditions, usually by a system of feedback controls, so as to…

have three tissue layers, ectoderm, mesoderm, and endoderm (Newmark and Alvarado, 2001). Their epidermal layer that surrounds the planarian is ciliated on the ventral surface (Newmark and Alvarado, 2001). Underneath the epidermal layer and the basal lamina, followed by a complex wall musculature that surrounds the body. The complex wall muscle is composed of the circular diagonal and muscle fibers (Newmark and Alvarado, 2001). The nervous system contains two ventral nerve cores. The nerve…
