lifespan‚ and pumps approximately 4.7-5.7 litres of blood per minute. It weighs approximately in females and in males. Structure The structure of the heart can vary among the different animal species. Cephalopods have two "gill hearts" and one "systemic heart". In vertebrates‚ the heart lies in the anterior part of the body cavity‚ dorsal to the gut. It is always surrounded by a pericardium‚ which is usually a distinct structure‚ but may be continuous with the peritoneum in jawless and cartilaginous

Have you ever wondered which body system helps bring oxygenated and deoxygenated blood to the heart? Well that system is called the Circulatory System or the Cardiovascular System. Have you ever wondered which body system helps bring air into the lungs? That system is called the Respiratory system. You are probably wondering why I am mentioning the Respiratory and Circulatory system? I am talking about them because‚ these are the two system that I am going to be comparing and contrasting in this

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 muscle) is a specialised form of muscle
