Number the steps below as they occur during normal cardiac circulation from the body, beginning with deoxygenated blood returning to the heart.

The question is incomplete as it does not have the options which are:

(A) Blood is distributed by the aorta to the body

(B)  Blood flows through tricuspid valve

(C)  Blood enters right ventricle

(D)  Blood flows through mitral valve

(E)   Blood enters right atrium

(F)   Blood enters the left ventricle

(G)  Blood flows through pulmonary valve

(H)  Blood goes through the pulmonary artery to the lungs

(I)  Blood enters left atrium

(J)   Blood flows through aortic valve

1. Blood enters right atrium

2. Blood flows through tricuspid valve

3. Blood enters right ventricle

4. Blood flows through pulmonary valve

5. Blood goes through the pulmonary artery to the lungs

6. Blood enters left atrium

7. Blood flows through mitral valve

8. Blood enters the left ventricle

9. Blood flows through aortic valve

10. Blood is distributed by the aorta to the body

Explanation:

The circulation of the blood in the body through the heart is known as the cardiovascular system. The blood is pumped by the heart which begins with the entry of the deoxygenated blood from the body in the right atria located in the upper right of the heart.

The contraction pumps the blood to the right ventricle where the tricuspid valves present between right atrium and ventricle prevents the backward movement of the blood. The blood then enters the pulmonary artery to the lungs where it gets oxygenated.

The oxygenated blood then enters the left atrium and then to the left ventricle through bicuspid valves. Blood then leaves the heart to the body through the aorta where the aortic valve prevents the backflow of the blood into the heart.

Thus, the options arranged in the sequence are correct.

answer; the national uniform billing committee(nubc);

this disease is :

* endemic (present in a defined area that is a village)

* a bacterial infection (treated with antibiotic)

* communicable by contact (by the hands)

manu-porterage is the most common mode of transmission, it transmits germs from one individual to another via the hands. this concerns infections of exogenous origin.

endemic disease, or endemic disease, refers to a disease that is constantly present in a given population, often tied to a specific geographic origin, as opposed to a pandemic that is not a sporadic disease.

antibiotics are molecules that have the property of killing (bactericidal) or limiting the spread (bacteriostatic) of bacteria.
