Question

Path of Blood in the Body In adult mammals, including humans, the heart is a double pump. The right ventricle po pulmonary circuit-to the lungs and back to the heart (Fig. 16:3). While the blood up carbon dioxide and gains oxygen. The left ventricle pumps blood to the systemic whole body except to the lungs. Blood in the systemic circuit gives up oxygen and gains Figure 16.3 shows the path of blood in both the pulmonary and systemic circuits in helps you to learn the names of some of the major blood vessels. the heart (Fig. 16.3).

Answer 1

It would have been better if figure 16.3 was also attached.

Correct answers:

1.Pulmonary Circuit:

Right ventricle of heart --- Pulmonary artery --- Lungs --- Pulmonary vein --- Left atria of heart.

2. Systemic circuit:

Left ventricle of heart --- Dorsal aorta --- renal artery --- kidney --- renal vein --- vena cava --- right atria of heart.

3.

Heart: Coronary artery, Coronary vein

Head : Carotid artery, Jugular vein

Arm : Subclavian artery, Subclavian vein

Kidney : Renal artery, Renal vein

Legs : Iliac Artery, Iliac vein

Intestine: Leino gastric Artery, Hepatic portal vein.

4. Hepatic portal vein lies between digestive tract and liver.
