Answer :
Levels of Organization:
1. CELL - d. made up of organelles; basic unit of life
2. TISSUE - a. a group of cells with a similar function
3. ORGAN - c. a group of tissues that have a similar function
4. ORGAN SYSTEM - b. group of organs
Endocrine System:
1. The endocrine system is made up of glands.
2. An example of a hormone is adrenaline.
3. Hormone levels are controlled by feedback mechanisms.
Nervous System:
1. The brain and nerves are part of the nervous system.
2. The nervous system and the endocrine system are called the control systems.
Circulatory System:
1. The function of the circulatory system is to transport nutrients and oxygen throughout the body.
2. The heart is the major organ of the circulatory system. Its function is to pump blood.
3. Red blood cells carry oxygen.
4. White blood cells clot the blood, and carbon dioxide is released as waste.
Respiratory System:
1. The function of the respiratory system is gas exchange.
2. Oxygen is breathed in while carbon dioxide is exhaled as waste.
Immune System:
1. The job of the immune system is to protect the body against pathogens.
2. Types of pathogens include bacteria, viruses, and parasites.
3. Blood cells are the main cells of the immune system.
By understanding the different levels of organization in the body and the functions of various body systems like the endocrine, nervous, circulatory, respiratory, and immune systems, we can appreciate how each system works together to maintain overall health and well-being.
