Body Systems 1
What are the main parts of the circulatory system?
heart and blood vessels
What is the main function of a cell organelle?
energy production, protein synthesis, and waste disposal.
What are the two main body cavities?
Dorsal and Ventral
What is the role of the circulatory system?
to transport vital substances, like oxygen, nutrients, and hormones, to all body cells, tissues, and organs, while simultaneously removing waste products, such as carbon dioxide.
How does the immune system protect the body?
through its innate and adaptive responses, acting as a defense against pathogens like bacteria and viruses, toxins, and tumor cells.
What is the function of the respiratory system?
to provide oxygen to cells
Which organelles are found in eukaryotes but not prokaryotes?

What type of tissue lines body cavities?
Membranes, such as meninges and serous membranes
How does the respiratory system facilitate gas exchange?
moving oxygen into the lungs and out of the body while bringing carbon dioxide from the blood into the lungs to be exhaled.
What provides structure and support to the body?
The skeletal system
Which organ system provides the body with its protective outer layer?

What is the main function of chloroplasts?
They are the site of photosynthesis in plant cells
What is the primary function of body cavities?

What are the two categories of controlled muscles?
voluntary and involuntary
How are the muscular and skeletal systems similar?
Both are involved in body movement
What is the role of lysosomes?
They are responsible for breaking down and recycling cellular waste and macromolecules.
What are the two main subdivisions of the dorsal cavity?
Cranial and Vertebral Cavities
How many bones are in the average adult body?

provides structural support and protection, enables movement, produces blood cells, and stores essential minerals
What systems are responsible for getting nutrients from food to the cells in your brain?
digestive and circulatory
What is the function of the nucleus?
Controls cell activity, contains DNA, and is involved in cell division.
What organ does the vertebral cavity contain?
The spinal cord
What waste products are removed by the kidneys?
urea, ammonia, and uric acid, along with excess water,and salt.
Which body system is known as the "master communicator" controlling others electrically?
