Why are the walls of ventricles thicker than the walls of atria ?
The walls of ventriclea are thichker because ventricles have to do more work as compare to atria. Ventricles pump blood into various organs and the pressure of blood flowing in them is more than that of articles.

See lessstate the role and functions of WBCs.
White blood cells, also known as leukocytes, are responsible for protecting your body from infection. As part of your immune system, white blood cells circulate in your blood and respond to injury or illness.

See lessWhat is the role of blood ?
Blood brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Blood also fights infections, and carries hormones around the body.

See lesswhat is special about blood capillaries?
Capillaries: These tiny blood vessels have thin walls. Oxygen and nutrients from the blood can move through the walls and get into organs and tissues. The capillaries also take waste products away from your tissues. Capillaries are where oxygen and nutrients are exchanged for carbon dioxide and wastRead more

See lessWhy is it important to prevent oxygenated and deoxygenerated blood from mixing in birds and mammals?
Separation of oxygenated and deoxygenated blood allows a highly efficient supply of oxygen to the body. This is useful in animals that have high energy needs, such as birds and mammals, which constantly use energy to maintain their body temperature.

See lessWhich animals can tolerate some mixing of the oxygenated and deoxygenerated blood stream?
Such animals, like amphibians or many reptiles have three-chambered hearts, and tolerate some mixing of the oxygenated and de-oxygenated blood.

See lessOn what factor does the body temperature of the animal depend?
For both endotherms and ectotherms, body temperature depends on the balance between heat generated by the organism and heat exchanged with—lost to or gained from—the environment.

See lessplants have low energy needs as compared to animals.Explain.
Plants do not need to move from one place to another. Movements in a plant are usually at the cellular level and hence a far less amount of energy is required by plants. Animals, on the other hand, need to move from one place to another; in search of food. So, the energy need of animals is pretty hiRead more

See lessWhat will happen if xylem tissue in plants is removed
If the xylem of the plant is removed, upward movement of water will stop leading to wilting of leaves and ultimately causes the death of a plant. In the absence of water, the plant will not be able to prepare food and also perform other essential activities.

See lessWhat will happen if we are injured and start bleeding?
Normally, when you are injured and start bleeding, a blood clot forms to stop the bleeding quickly. Afterwards, the clot dissolves naturally. To be able to make a clot, your blood needs blood proteins called clotting factors and a type of blood cell called platelets.
