The Heart is a pumping device that pumps blood. The heart of a fish is a two-chambered heart. It has one Auricle and one ventricle. Blood from all the parts of the body is sent to auricle, auricle pumps that blood to ventricle and ventricle pumps that blood to gills for the purpose of oxygenation. From the gills, oxygenated blood is supplied to ...
Right Atrium Our heart has four chambers, two atria (right and left) and two ventricles (right and left). The right atrium receives the de-oxygenated blood from the body. From the right atrium blood passes to the right ventricle. The right ventricle propels this de-oxygenated blood to the lungs though pulmonary artery, for oxygenation. The deoxygenated blood loses carbon-di-oxide and gains ...
The circulatory system pumps blood and respiratory system is the exchange of gases( carbon dioxide and oxygen) The difference between these two systems is: Circulatory system is only made up of the blood, heart, blood vessels, lymph nodes Respiratory System: Is only made up of the nose, pharynx, larynx, trachea, bronchi, bronchioles, alveoli(air sacs, where the gas exchange occurs) Unlike the ...
Myocardium Human heart has three layers in its wall. They are, from inside outwards : Endocardium Myocardium Pericardium Of these three layers, the endocardium is an endothelial lining. The myocardium is composed of cardiac muscle and the pericardium is the fibro-serous covering of the heart. Fig 1 : This diagram shows different layers of heart wall and their composition. Fig 2: A diagram of ...
Simply put, independent variables are inputs and dependent variables are outputs. For example, a graph showing the amount of time spent studying on a test vs. the average score gives clear examples of each. The independent variable, the time spent studying on a test, is the amount that we can vary. The dependent variable, or the test score, is based on the value of the independent variable.
Deoxygenated blood enters the heart via superior and inferior vena cava's then into the right atrium--> right ventricle then the pulmonary artery Oxygenated blood returns via the pulmonary veins-->left atrium-->left ventricle then up into the aorta. Look at this diagram to get a better understanding
Red = oxygenated blood Blue = non - oxygenated blood Correct me if I'm wrong, but I believe the blue blood vessels are to identify the veins in your circulatory system, carrying non-oxygenated blood back to the heart (because the oxygen has been diffused to the cells by capillaries for cellular respiration). The red blood vessels represent the arteries, they carry the oxygenated blood ...
The population P(t) of a species satisfies the logistic differential equation dp/dt=P{2-(P/5000)}, where initial population P(0)=3000 and t is the time in years.

Circulation of blood through vessels present around heart muscle is called coronary circulation. Heart is continuously working, hence needs continuous supply of oxygen in its muscles: this is achieved by supplying blood through left and right coronary arteries. The arteries arise from base of main aorta as it exits from left ventricle of heart. Coronary veins or Cardiac veins drain ...
