Each system is composed of organs and tissues which perform specific functions and interact with each other, e.g., digestion, gas exchange, excretion, circulation, locomotion, control, coordination, reproduction, and protection from disease.
Tissues, organs, and organ systems help to provide all cells with nutrients, oxygen, and waste removal.
The circulatory system moves substances to and from cells, where they are needed or produced, responding to changing demands.
Important levels of organization for structure and function include organelles, cells, tissues, organs, organ systems, and whole organisms.
Humans are complex organisms. They require multiple systems for digestion, respiration, reproduction, circulation, excretion, movement, coordination, and immunity. The systems interact to perform the life functions.
The components of the human body, from organ systems to cell organelles, interact to maintain a balanced internal environment. To successfully accomplish this, organisms possess a diversity of control mechanisms that detect deviations and make corrective actions.
The organs and systems of the body help to provide all the cells with their basic needs. The cells of the body are of different kinds and are grouped in ways that enhance how they function together.
The following is an assignment designed to help students make connections between the function and structure of the different human body systems (circulatory, respiratory, digestive, excretory and skleletal). This assignment is intended to be completed by students once they have learned about each of the systems.
