Both the cardiovascular and respiratory system help each other by working together to make sure that the tissues of the body are getting the correct amount of oxygen so that they can help the body to work efficiently as possible. They also help to make sure that carbon dioxide is forced out. The cardiovascular and respiratory system start to work together when the oxygen from the surroundings/environment enter through the nose‚ this will start the process where the body will receive the oxygen.

The cardiovascular system consists of the heart‚ blood vessels‚ and blood. This system has three main functions: Transport of nutrients‚ oxygen‚ and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide‚ nitrogenous wastes). Atria: Ventricles: In a four-chambered heart‚ such as that in humans‚ there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs‚ and the left ventricle pumps

When the blood circulates within our system‚ chemicals are exchanged by diffusion. Our cardiovascular system is made up of our heart‚ arteries and our veins. There is an important difference between the veins and the arteries. That difference is the flow or direction of the blood. Veins carry blood to the heart and arteries carry blood away from

-------------------------------------------------------------------------------- Experiment Results Predict Question: Predict Question 1: How will the conduction velocity in the B fiber compare with that in the A Fiber? Your answer : b. The conduction velocity in the B fiber will be slower because the B fiber has a smaller diameter and less myelination. Predict Question 2: How will the conduction velocity in the C fiber compare with that in the B Fiber? Your answer : d. The conduction

Case Study # 2: Age-Related Changes that Occur in the Cardiovascular System Sarah Miller ITT Technical Institute As the heart ages it goes through changes such as thickening of the walls‚ slowing heart rate‚ decrease in maximum heart rate‚ loss of efficiency in pumping. The layers of the heart include the pericardium‚ epicardium‚ myocardium‚ and endocardium. The pericardium is the membrane that protects; it is a sac that the heart sits in and has a layer of fluid between for shock and absorption
