Be able to describe the structures and functions of these systems and how they work together; (name at least one structure for each system (for example Digestive System Structured-Intestines stomach)d function: to digest and break down food particles to be used for energy. In 1 sentence.

Answer 1

Circulatory System: Heart - pumps oxygen-rich blood throughout the body to supply tissues with oxygen and nutrients.
Respiratory System: Lungs - facilitate the exchange of oxygen and carbon dioxide between the air and the bloodstream.
Nervous System: Brain - processes information, coordinates responses, and regulates bodily functions through electrical signals.
Musculoskeletal System: Bones - provide structure, support, and protection for the body while facilitating movement in conjunction with muscles.
Endocrine System: Glands (e.g., Thyroid) - secrete hormones that regulate metabolism, growth, and homeostasis within the body.
Digestive System: Intestines - absorb nutrients and water from digested food, allowing the body to utilize energy.
Immune System: Lymph Nodes - filter lymph fluid and facilitate the detection and response to pathogens to protect the body.
Reproductive System: Ovaries (in females) - produce eggs and hormones necessary for reproduction and regulation of the menstrual cycle.
Integumentary System: Skin - acts as a protective barrier, regulates temperature, and provides sensory information.

These systems interact closely; for example, the circulatory system delivers oxygen from the respiratory system to cells, while the digestive system supplies nutrients essential for energy production in all other systems.
