Test: Transportation In Human Beings - Class 10 MCQ

They pick up oxygen in your lungs and carry it to your body's tissues and organs. Your blood then transports carbon dioxide back to the lungs where you can breathe it out. Red blood cells pick up oxygen in the lungs.

The extracellular matrix of blood is called plasma. Plasma is the fluid part of the blood in which the red blood cells, white blood cells and platelets are suspended. It is a specialized bodily fluid that supplies essential substances and nutrients, such as sugar, oxygen, and hormones to our cells, and carries waste away from those cells, this waste is eventually flushed out of the body in urine, feces, sweat, and lungs (carbon dioxide). Blood also contains clotting agents that prevents extra blood loss

From the left atrium blood  flow into the left ventricle. The left ventricle pumps the blood to the aorta which will distribute the oxygenated blood to all parts of the body.

The flow of blood to tissues beyond the clot may be cut off. A clot may block the flow of blood to the tissues beyond the clot and cutting off food and oxygen to those tissues. If a clot blocks an artery that nourishes the heart then a heart attack may occur. If a clot blocks an artery to the brain, a stroke may occur.

The Circulatory System is made up of three main parts: The heart, the blood vessels and the blood. Sometimes the watery fluid called lymph and the vessels that carry it are considered to be part of the Circulatory System. The heart is a special pump that pumps the blood around the body.

Lymph differs from blood in possessing only WBC. Lymph is the fluid that circulates throughout the lymphatic system. Lymph contains white blood cells certain proteins while RBCs are absent. 

Aorta is a vessel which carries blood from heart to different parts of body and veins are those type of vessels which carries impure blood from body parts to heart.

Your blood is made up of liquid and solids. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets.
