Systemic circulation is the one that oxygenates all the body.
Starting from the left atrium, through the left ventricle, and the aorta and its branches to the body.
After the tissues do the exchange, the deoxygenated blood goes back to the right atrium to starts the pulmonary circulation, and then the cycle starts again.

Answer
secondary consumers
Explanation
Secondary consumers are organisms which eat or depend on primary consumers. Primary consumers are those organisms that feed on plants, they are mainly herbivores and occupy second trophic level.-
Scavengers are organisms that mostly consume decaying organisms or matter, such as meat or rotting plant material. They are types of carnivores, which feed on meat, however, unlike carnivores which hunt and kill their prey, scavengers consume dead animals ad plants.
Secondary consumers occupy the third trophic level and include scavengers, other carnivores, and omnivores (consume both plants and animals).
Answer:
Blood is composed of several types of cells:
- <u>RED BLOOD CELLS</u>: They are the oxygen carriers of the body i.e. they pick up the oxygen as the blood goes through the lungs & release of oxygen to cells.Also known as erthrocytes
- <u>WHITE BLOOD CELLS</u>: also known as leukocytes.They are the soldiers of the body.Aims at fighting against the infections ( caused by bacteria & virus)
- <u>PLATELETS</u> : helps in the blood clot in response to any wound or injury
There are five types of white blood cells & approx %age they made up in blood are:
•Neutrophils (55% to 70%)
•Band neutrophils (0% to 3%)
•Lymphocytes (20% to 40%)
•Monocytes (2% to 8%)
•Eosinophils (1% to 4%)
•Basophils (0.5% to 1%)
When children are more than 4 year old they have higher % age of lymphocytes than the adults do.
