Answer:
DRUGS !!!!!!!!!
WHAT DO YOU WANT WITH DRUGS? THAT'S MY QUESTION.
These are the 3 different types of circulation. Not sure if it matters which box you put them in or what..? Don't quite get that chart. But luckily I had a similar question on one of my old assignments. Don't know if you needed definitions but here you go,
Pulmonary circulation: This part of the cycle carries oxygen-depleted blood away from the heart, to the lungs, and back to the heart.
Systemic circulation: This is the part that carries oxygenated blood away from the heart and to other parts of the body.
Coronary circulation: This type of circulation provides the heart with oxygenated blood so it can function properly
Sponges are similar to a small intestine because they'll both squeeze parts of themselves to digest foods and nutrients. Not to mention the fact that they're both soft.
Hope this helped! <3
Answer:
Options B and D
Explanation:
In animals, gaseous exchange takes place in the alveoli in the lungs. Generally, animals breath-out (exhale) carbon dioxide and breath-in (inhale) oxygen. Thus, carbon moves from the blood in the form of carbon dioxide into the alveoli in the lungs while the oxygen inhaled moves from the alveoli in the lungs to the blood where it is transported round the body as oxyhaemoglobin.
