The integumentary system includes the epidermis, dermis, hypodermis, associated glands, hair, and nails. In addition to its barrier function, this system performs many intricate functions such as body temperature regulation, cell fluid maintenance, synthesis of Vitamin D, and detection of stimuli.
Answer:
The answer to the statement: At rest, most of the body´s blood supply resides in the pulmonary loop, would be, B: False.
Explanation:
The circulatory system never stops working. Pumping of blood, transportation of oxygen, nutrients and water to and from tissues is a process that does not end, even during sleep. The only moment when this process does not happen, is in death. However, a good question is, where does the blood go, or stay, when the body is not active, like for example, during sleep. And the answer is that most of it will rest on the systemic veins and venules and will slowly circulate back to the heart, but at a much lower rate than when the body activates itself. However, what is not true is that blood will reside mostly in the pulmonary loop, because this loop does not have the capacity to store that much blood.
Heart attacks happen suddenly when one of the arteries leading to the heart becomes blocked and cuts off the blood flow. Without oxygen, the heart muscles start to die.
Heart failure, on the other hand, usually develops gradually. The heart muscle becomes weaker and has trouble pumping blood to nourish the cells in your body. This is a chronic condition that gradually gets worse. But medications can help you live longer and better with it
