The main difference between the pulmonary and systemic circulation is in where the blood goes.
In pulmonary circulation, blood is carried to and from the lungs, where it comes in contact with the oxygen-exchange surfaces of the lungs. On the other hand in systemic circulation blood runs to and from the cells in the rest of the body.
Another difference is that in regard to the pulmonary circulation, blood that has completed the pulmonary circuit is rich in oxygen while in systemic circulation, blood that has completed the systemic circuit has been depleted of oxygen
.
The cardiovascular system has two distinct routes: the pulmonary circulation and the systemic circulation.
The flow of blood between the heart and the lungs is the center of the pulmonary circulation. The pulmonary arteries carry deoxygenated blood from the right ventricle of the heart to the lungs. The process of oxygen absorption and carbon dioxide emission in the lungs creates oxygenated blood. After returning to the heart via the pulmonary veins, oxygenated blood enters the left atrium before being pumped to the rest of the body.
On the other hand, systemic circulation involves the transfer of oxygenated blood throughout the body. Oxygenated blood from the pulmonary circulation enters the left atrium, which contracts to pump it into the left ventricle. The left ventricle continues from there. , The oxygenated blood is then pumped from the lungs by the left ventricle into the aorta, where it splits into smaller arterioles and arterioles before reaching the capillaries.
Waste products such as carbon dioxide collect in the capillaries, where oxygen and nutrients are exchanged with the body's cells. To restart the pulmonary circulation process, the deoxygenated blood is returned to the heart by the veins, and is collected in the veins along the way.

It is not necessary to wear sunscreen during recreational activities when it is indoors. Therefore, option D is correct.
Sunscreen shields keep skin safe. They are crucial in preventing the skin from absorbing ultraviolet (UV) radiation. Sunburns and skin cancer are both caused by UV radiation, which also affects the skin.
Your elastin, collagen, and skin cells can become damaged from repeated sun exposure with little to no protection. This can eventually result in early ageing symptoms such as discolouration, wrinkles, fine lines, and a leathery appearance. People who spend time in the sun without protection, especially those in their 20s and 30s, are more likely to experience photoaging, or premature ageing. Thankfully, consistent sunscreen use can avoid these skin problems.
It is not necessary to wear sunscreen when recreational activities are indoors and at night. Therefore, option D is correct.
