Circulatory System Essay

is pulled into the lungs. When the diaphragm relaxes, carbon dioxide is pumped out of the lungs. The cardiovascular system is part of the larger circulatory system, which circulates fluids throughout the body. The circulatory system includes both the cardiovascular system and the lymphatic system. The cardiovascular system moves blood throughout the body, and the lymphatic system moves lymph, which is a clear fluid that’s similar to the plasma in blood. Blood contains nutrients from the foods you

1. Circulatory System’s Structure and Function  The purpose of the circulatory system is to transport materials throughout the body. The human circulatory system has 3 major components that allow it to transport materials throughout the body, which are blood, blood vessels, and heart. The human circulatory system is a closed system that cycles blood through three different circuits: cardiac circulation, which means blood moves within the heart muscle. Pulmonary circulation, blood travels from the

which the structure of a certain specimen corresponds to its main function. Examples that show this include the mammals’ circulatory system, the respiratory systems of fish and countercurrent exchange, antibodies, tRNA and the replication of DNA, vertebrate skeletons, and muscles and their contraction. The mammals’ circulatory system, as well as the blood they carry, have such a system in which structure plays a big role. Blood transports substances throughout the body. Suspended in the plasma of its

The heart and Circulatory System Coronary Circulation Coronary circulation is the circulation of blood in the blood vessels of the myocardium (heart muscle). Coronary arteries deliver oxygen-rich blood to the myocardium. Cardiac veins remove the deoxygenated blood from the myocardium. As the left and right coronary arteries run on the surface of the heart, they can be called Epicardial coronary arteries. These arteries, when healthy, are capable of auto regulation to maintain coronary blood flow

tissues, and cells throughout the body. Blood sends nutrition and oxygen to the cells and carries waste products and carbon dioxide out of the body (From The Heart, 2002). There are two loops that make up the circulatory system. This is the main role that the heart plays in the circulatory system. One loop carries oxygen poor blood from the heart to the lungs for oxygen with the second loop carrying oxygen and food to the tissues and cells (From The Heart, 2002). The heart’s structure helps

The Digestive System 1.1 The digestive system is comprised of a group of organs known as the alimentary canal, which is one continues tube that runs from the oral cavity to the anus. The second set of organs that make up the digestive system are the Accessory organs. The digestive system has six main functions: ingestion, secretion, mixing and movement, digestion, absorption, and excretion of food (Tortora & Derrickson, 2009). Alimentary canal Organ Structure Function Diagram Mouth The mouth is made

The circulatory system is made up of vessels and pumps that helps transport nutrients and oxygen throughout the body. The vessels and pumps help circulate the blood through the structures of the body systems. The heart is at the centre of the circulatory system. The heart helps pump blood throughout the whole body, and the blood goes back to the heart in a circular motion going round in a circle but it goes around the body and body systems. The cells within the body get their nutrients from both

respiratory system. In a mammal, the lungs function in the respiratory system by providing a large surface area for incoming oxygen to enter and the removal of carbon dioxide gas from the mammal’s body providing highly efficient respiration. In contrast to mammals, insects obtain required oxygen for respiration through a series of small openings called spiracles that are found in the insect’s

Circulatory - An acute response in relation to the circulatory system would be an increase in stoke volume. An increased stroke volume allows oxygen demand by the muscles to be met by oxygen supplier through bigger heart contractions. Respiratory - Is the exchange of gases, which occurs at the alveolar-capillary membrane as the blood becomes oxygenated before returning to the heart and being circulated towards the muscles. A larger volume of oxygen can be diffused into the blood stream because

The Circulatory System The circulatory system in anatomy and physiology is the course taken by the blood through the arteries, capillaries, and veins and back to the heart. In humans and the higher vertebrates, the heart is made up of four chambers the right and left auricles, or atria, and the right and left ventricles. The right side of the heart pumps oxygen-poor blood from the cells of the body back to the lungs for new oxygen; the left side of the heart receives blood rich in oxygen from
