Cardiovascular system: The circulatory system: The circulatory system is made up of the vessels and the muscles that help and control the flow of the blood around the body. This process is called circulation. The main parts of the system are the heart‚ arteries‚ capillaries and veins. As blood begins to circulate‚ it leaves the heart from the left ventricle and goes into the aorta. The aorta is the largest artery in the body. The blood leaving the aorta is full of oxygen. This is important for

The SA (sinoatrial node) is a pacemaker that is in the right atrium of the heart. SA node control the heart rate using the electrical impulses that sends to the heart muscles and this is how the heart pumping blood out to the entire body and how the heart contract. The stages of the pathway of action potential: 1) The Action Potential is in the Sinoatrial node (SA). Action potential then travels from the SA node to the AV (atrioventricular node) by crossing to the wall of the atrium. 2) Then the

Cardiovascular System Anatomy & Physiology The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body. It is a four-chamber pump‚ with the right side receiving deoxygenated blood from the body at low presure and pumping it to the lungs (the pulmonary circulation) and the left side receiving oxygenated blood from the lungs and pumping it at high pressure around the body (the systemic circulation). The myocardium (cardiac

In this article‚ we’ll explore a few of the most common simple CHDs‚ including septal defects and valve problems. Atrial Septal Defect Inside the heart‚ the left atrium and ventricle are separated from the right atrium and ventricle by a wall. This wall is called the septum. It prevents deoxygenated

The Endocrine system helps to maintain homeostasis by secreting hormones into the bloodstream‚ which travels throughout the body. This system regulates activities such as growth and development and influence emotions and behavior. The relationship of this system alongside the other body systems is how the body maintain a stable equilibrium‚ regulating the activity of the organ systems. Nervous - The endocrine system acts as a communication tool within the human body‚ working alongside with the nervous
