answer me right you get brainliest what do i put in here

Answers

Answer:

It encourages healthy eating but emphasising the smaller quantity of fats and larger quantity of carbohydrates one should eat, for example.

How can an individual become an organ donor in many states?

by telling a spouse or significant other

by carrying a handwritten note describing one’s wishes

by discussing it with a nurse at an annual physical

by signing up when renewing a driver’s license

Answers

“When you last renewed your driver's license, you may have checked the box to become an organ donor. Or you may have skipped it. And you may have chosen either option without thinking about it too much, or without truly understanding the decision you were making.

Choosing whether to be an organ donor is certainly a personal decision, but it really is a heroic one - and one that you, as an individual, can make on your own.

"In many ways, being an organ donor is one of the greatest gifts you can give," said Dr. Michael R. Marvin, director of transplantation and liver surgery for Geisinger. "It's a very selfless act because you most likely won't know the recipients, but by choosing to donate, you are saving or improving the lives of many people."

One organ and tissue donor can save and enhance the lives of up to 50 people. An organ donor can give a second chance at life to up to eight people. Through tissue donation, a donor can enhance the lives of countless others through bone donations to repair fractures and prevent amputations, skin donations to heal burn patients and heart valve donations to repair life-threatening defects. Donors can also donate their corneas, which can give the gift of sight to recipients.

Last year, more than 30,000 organ transplants were performed in the United States.

"Even with all of our success, there is still work to do in educating the public about the critical need to register more organ and tissue donors," Dr. Marvin said. "The statistics are frightening. Currently in the United States, 21 people on average die each day because there aren't enough life-saving organs available for transplant."

According to the Gift of Life Donor Program, over 8,400 Pennsylvanians are waiting for a life-saving organ transplant. Residents who have a driver's license or state identification card can go online and add the donor designation to their record. You can also register online at www.donors1.org.

"You no longer have to wait until you renew your driver's license or state identification card. It's a quick and easy process to register online," Dr. Marvin said.” Sorry for the top guy hope this helps can you mark me brainiest?

An individual can become an organ donor in many states by signing up when renewing a driver’s license.

Who are organ donors?

Organ donors are those individuals that officially declare the interest of allowing their organs to be transplanted to another person who is in need of it for health purposes.

To become an organ donor in any state, you can use the opportunity of filling out an organ donor card when you get or renew your driver's license.

Therefore, an individual can become an organ donor in many states by signing up when renewing a driver’s license.

List the types of vessels in the order a drop of blood would flow through in the in the systemic circulatory route beginning with the aorta. which come first capillary, vein , artery, venule, arteriole. In anatomy

Answers

Answer:

The types of vessels through which a drop of blood would flow in the systemic circulatory route starting from the aorta are: artery, large, medium and small caliber → arteriolescapillary vesselsvenuleveins, small, medium and large caliber.

Explanation:

The circulatory system is part of the cardiovascular system and consists of the blood vessels responsible for carrying blood throughout the body. Each of the blood vessels branches off, forming large-, medium-, and small-caliber vessels.

Arteries carry oxygenated blood from the heart to all body tissues and organs.The capillary vessels are very small in caliber and allow the exchange of blood, nutrients and gases with the tissues.Veins are in charge of taking non-oxygenated blood from the whole body and carry to the heart.

From the heart the blood passes to the lungs so that the alveolar gaseous exchange occurs.

If a drop of blood is found in the aortic artery, its pathway through the systemic circulatory route is:

Artery, large, medium and small caliber → arteriolescapillary vesselsvenuleveins, small, medium and large caliber.

Right image: visceral, smooth, involuntary

Explanation:

The image you attached shows two kinds of muscles: the skeletal muscle (left side) and the smooth muscle (right side).

The "skeletal muscle" is the muscle responsible for the body's voluntary movements. Their fibers appear striated, tubular and multinucleated. They are attached to the skeleton.

The "smooth muscle," like the cardiac muscle, is the muscle responsible for the body's involuntary movements. Its fibers are nonstriated and nonnucleated. They can be found in the wall of hollow organs like urinary bladder, uterus, intestines, etc.
