Answer:
Systolic blood pressure
Explanation:
The contraction of the heart that allows blood to pump is the systole and the relaxation of heart after contraction is the diastole. These are the two phases of the cardiac cycle. The systolic blood pressure is more important than diastolic blood pressure as it provides the ideas of heart attack or stroke.
The increase in the systolic pressure and low or normal diastolic pressure is called ISH (Isolated Systolic Hypertension). This is an indication of high risk of heart attach or stoke. The diastolic pressure is sometimes important in detecting risk of heart attack in individual below the age of 40 years. The younger individuals are less prone to heart attack risks.
Answer:
The correct answer is - red blood cells are biconcave.
Explanation:
RBC or the red blood cells are the cells that play an important role by many means such as transferring nutrients, hormones, and oxygen throughout the body. The transfer of the oxygen is accompanied by the help of hemoglobin, a protein that carries oxygen and takes it to the different sites in the body.
These cells are biconcave which helps them to provide more cell surface area to grab or attain maximum space for hemoglobin which helpful in oxygen significant oxygen-carrying capacity of Red blood cells.
Thus, the correct answer - red blood cells are biconcave.
