1) Starting from deoxygenated blood returning to the heart, place the following steps in order as blood passes through the heart:
- 1. 2. 3. 4. 5. 6. 7.
blood passes through the tricuspid valve
blood exits the left ventricle via the aortic valve
oxygenated blood enters the heart via the pulmonary veins
blood is carried to the body via the aorta
blood passes from the left atrium into the left ventricle
blood enters the right atrium
blood leaves the right ventricle through the pulmonary valve
2)
Which of the following is correct regarding the cardiovascular system?
the aorta is where oxygen-rich blood leaves the heart for the lungs. |
||
pulmonary veins carry oxygen-poor blood. |
||
pulmonary arteries carry oxygen-poor blood. |
||
blood in the pulmonary circuit goes to the brain only |
3)
The main difference between the pulmonary circuit and the systemic circuit of the heart is that in the pulmonary circuit:
oxygen-rich blood leaves the heart for the lungs. |
||
pulmonary veins carry oxygen-poor blood. |
||
pulmonary arteries carry oxygen-poor blood. |
||
blood in the pulmonary circuit goes to the brain only |
1. Heart is a large muscular organ which pumps oxygenated blood to the brain and different parts of the body and transports deoxygenated blood from the brain and other parts of the body to the lungs. Blood enters the heart through the inferior vena cava and superior vena cava. Blood enters the right atrium (6 ) blood passes through the tricuspid valve (1 ) blood leaves the right ventricle through the pulmonary valve (7 ) oxygenated blood enters the heart via the pulmonary veins(3 ) blood passes from the left atrium into the left ventricle (5 ) blood exits the left ventricle via the aortic valve (2 ) blood is carried to the body via the aorta (4 ).
2. The pulmonary arteries carries deoxygenated blood from the right ventricle to the lungs. Hence correct statement regarding the cardiovascular system is pulmonary arteries carry oxygen-poor blood.
3. in the pulmonary circuit blood takes up oxygen in the lungs. De oxygenated blood carried to the lungs through pulmonary arteries. Hence option is pulmonary arteries carry oxygen-poor blood.
