Question 6

vessels that carry deoxygenated blood from the right ventricle of the heart to the lungs

Answer 6

Pulmonary arteries

Question 7

Circulation of blood between the heart and the lungs, portions of the circulatory system that relates to the lungs

Answer 7

Pulmonary circulation

Question 8

Answer 8

Pulmonary trunk

Question 9

Deliver oxygen rich blood from the lungs to the left atrium

Answer 9

Pulmonary veins

Question 10

Nerves that begins at the AV node in the atrium, extend down the septum + out into the ventricle walls, cause ventricles to contract

Answer 10

Purkinje fibres

Question 11

Blood cells that carry oxygen from the lungs to the body cells, cells that are mass produced by the red bone marrow, contains hemoglobin, Co2 + hydrogen in blood

Answer 11

Red blood cells

Question 12

Blood vessels that carries blood to the kidney

Answer 12

Renal artery

Question 13

Blood vessels that carries blood away from the kidney and towards the heart

Answer 13

Question 14

Receives deoxygenated blood from the body through the anterior and posterior vena cava, passes blood along to the ventricles to be pumped out of the heart

Answer 14

Right atrium

Question 15

Pumps deoxygenated blood to the lungs, marks the beginning of the pulmonary circut

Answer 15

Right ventricle

Question 16

Located in the right atrium, receives the message from the brain and causes the contraction of the atria, then sends an impulse to the AV node to stimulates its activity

Answer 16

Sinoatrial node (SA)

Question 17

Valve with flaps resembling a half moon, located between the ventricles + their attached blood vessels
- Prevent backflow of blood into ventricles
- blood must go through them to exit the heart
