Answer: A. A blockage in the aorta
Explanation:
A heart attack happens when one or more aorta or coronary arteries get blocked. With the passage of time, the coronary artery becomes narrow that is because of the deposition of various substances such as fat, cholesterol and other reserves. This restricts the smooth circulation of blood hence results in heart attack or heart stroke.
Answer:
The correct answer will be option-A
Explanation:
The centrifugation of the blood shows that 45% of the blood is composed of the cellular content and 55% blood plasma or liquid.
Erythrocytes or red blood cell constitute for about 41% of the total blood cells which transports the oxygen by binding it to the haemoglobin. The presence of haemoglobin is the reason the cell appears red which cause the color of the blood to appear red.
The remainder of the cell is white blood cells or leukocytes which play important role in providing the defence mechanism against the pathogen.
Thus, option-A is the correct answer.
