Answer:

Jaap de Roode is a biologist that featured on TEDTalks so the question links to him.

When they have an upset stomach, both dogs and cats will often eat grass to induce vomiting (self medication).

The risk in using man-made medicine when treating certain pathogens includes a tendency for the pathogens to develop into a resistant strain.

Just like humans, the monarch butterfly sometimes gets sick thanks to a nasty parasite. Monarchs survives with milkweed; their caterpillars eat milkweed plants only (Asclepias spp.), and monarch butterflies need milkweed to lay their eggs.

But biologist Jaap de Roode noticed something interesting about the butterflies he was studying - infected female butterflies would choose to lay their eggs on a specific kind of plant that helped their offspring avoid getting sick. How do they know to choose this plant? Think of it as "the other butterfly effect"- which could teach us to find new medicines for the treatment of human disease.

Explanation:

This leads scientists to think of improving Medicine so as to raise offsprings which are resistant to the parasites and diseases that killed their parents.

regulates blood volume and pressure, stimulates red blood cell formation, and controls fluid, electrolyte, and acid-base balance
omeli [17]

The Circulatory  system regulates blood volume and pressure, stimulates red blood cell formation, and controls fluid, electrolyte, and acid-base balance.

What is Circulatory  system?

To obtain oxygen into the blood, the circulatory system (cardiovascular system) pumps blood from the heart to the lungs. The remainder of the body receives oxygenated blood from the heart via arteries. Oxygen-depleted blood is returned to the heart by veins to restart circulation.

The human body is a tremendously intricate structure with numerous organ systems, including the brain, which regulates all bodily functions, lungs, which assist in gas exchange, and kidneys, which filter out waste products. However, the circulatory system controls all of these since blood is a fluid that keeps the body free of any materials that are not necessary for the body.
