How things flow through the heart: • blood drains into the right atrium through the superior vena cava‚ inferior vena cava‚ and the coronary sinus (drains the heart muscle itself)→Right Ventricle→pulmonary semilunar valves→lungs→pulmonary veins→left atrium→bicuspid valve→left ventricle→aortic semilunar valve→systemic circuit. What the valves do: • Prevent backflow into the atria and ventricles‚ ensuring that blood only flows one way through the heart. what vessels bring blood to the heart and

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

Terms | Definitions | Explan why the larger waves seen on the oscilloscope represent ventricular contraction | the ventricle contraction is of greater force than the atrial contraction‚ this is due to the fact that ventricle’s fxn is to send blood throughout the body. | Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation in cardiac muscle. | amplitude does not change because the cardiacs long refractory period prevents summation. | Why is

1. PEOPLE WILL FEEL AWKWARD‚ILL –AT-EASE AND SELF-CONSCIOUS :- Whenever we ask people to do things differently‚ you disrupt their habitual ways of doing things. This tends to make people feel awkward or uncomfortable as they struggle to eliminate the old responses and learn the new. 2.
