The blood pressure in different blood vessels in the body is as follows: Artery \(>\) arteriole \(>\) capillary \(>\) venule \(>\) vein (venae cavae). Since, the pressure is higher in artery than in veins hence, the pressure in pulmonary artery will be more than in pulmonary vein.

1 Open Close
2 Close Open
3 Open Open
4 Closed Closed
Explanation:
During ventricular systole, the bicuspid and tricuspid valves close and the semilunar valves open.

Rate of heartbeat is determined by
1 SA node
2 AV node
3 Purkinje fibres
4 Bundle of His
Explanation:
The SAN can generate the maximum number of action potentials, i.e., 70-75 \(\mathrm{min}^{-1}\), and is responsible for initiating and maintaining the rhythmic contractile activity of the heart. Therefore, it is called the pacemaker. Our heart normally beats \(70-75\) times in a minute (average 72 beats \(\mathrm{min}^{-1}\) ).

Blood pressure in pulmonary artery is
1 Same as that in the aorta
2 More than that in the carotid
3 More than in the pulmonary vein
4 Less than in the venae cavae
Explanation:
The blood pressure in different blood vessels in the body is as follows: Artery \(>\) arteriole \(>\) capillary \(>\) venule \(>\) vein (venae cavae). Since, the pressure is higher in artery than in veins hence, the pressure in pulmonary artery will be more than in pulmonary vein.
