Briefly explain the process of double circulation with the help of flow chart?

Laxmi Narayan 5 years, 2 months ago

Double Circulation The heart is the key organ for blood circulation and the double circulation is an efficient way of circulation as it provides an effective way of circulation. The main difference is that the blood follows two routes – one for oxygenated blood and the other for deoxygenated blood. Hence, the name “double circulation.” The majority of mammals, including humans utilize a double circulatory system. The human heart is divided into four chambers: Left Atria Right Atria Left Ventricles Right Ventricles Further, the heart is connected to the lungs through the pulmonary artery and vein. In double circulation, there are two pathways in which the blood flows. They are: Systemic circulation Systemic circulation carries oxygenated blood from the left ventricles to the tissue capillaries. The oxygen-rich blood is transferred to the aorta for circulating into various parts of the body. Later, the veins and venules collect the deoxygenated blood – which is rich in carbon dioxide from various parts of the body. The deoxygenated blood is pumped back into the superior vena cava and then to the right atrium. Once, after receiving the deoxygenated blood, the right atrium carries blood to the right ventricle for pulmonary circulation. Pulmonary circulation In the pulmonary circulation, the blood circulation starts from the right atrium to the left atrium. In this pathway: The pulmonary artery collects the blood from the right ventricle and carries to lungs for oxygenation. Once, after the purification process, the oxygenated blood is pumped back to the left atrium through the pulmonary vein which is carried to the left ventricles. The left ventricles pump the oxygenated blood to the aorta for systemic circulation. Double circulation supports a strict separation of both oxygenated and deoxygenated blood. Therefore, this circulation ensures that the body always has a dedicated supply of oxygen and also, it improves body efficiency. This is also one of the reasons why mammals can maintain their body temperatures. Apart from the double circulation, a third portal system also exists to improve circulation efficiency.

Why do multicellular organisms use complex way of reproduction?

Posted by Deepika Sharma 4 years, 10 months ago

CBSE > Class 10 > Science

Sia ? 4 years, 10 months ago

Multicellular organisms cannot reproduce by cell because they are not simple random collection of cells. In them, specialised cells are organized as tissues and tissues are organised into organs, which then have to be kept at different positions in the body. Cell-by-cell division would be impractical. Multicellular organisms, therefore, require to use more complex ways of reproduction. Moreover, simple multicellular organisms possess special type of tissues which have the potential to grow into a new organism but complex multicellular organisms have no such specialised cells.

Good Day 5 years, 2 months ago

Mammals have a double circulatory system. This means that during a single cycle, the blood goes twice in the heart. There are two loops in which blood is circulated. One loop is oxygenated and the other is de-oxygenated. This double circulatory system is important because it ensures provision of oxygenated blood to the muscle and not a mixture of oxygenated and de-oxygenated blood. Hence, this system ensures efficient supply of oxygenated blood to the muscles.

Types of Decomposition Reactions Decomposition reactions can be classified into three types: Thermal decomposition reaction Electrolytic decomposition reaction Photo decomposition reaction Thermal decomposition is a chemical reaction where a single substance breaks into two or more simple substances when heated. The reaction is usually endothermic because heat is required to break the bonds present in the substance. Examples: Photo decomposition is a chemical reaction in which a substance is broken down into simple substances by exposure to light (photons).
