PRIMARY PURPOSE: transport blood throughout the body by circulating. PRIMARY Kidneys and Lungs have a close relationship with Cardiovascular system. For more information on the connection between body systems, talk to your health professional at Revere Health. We offer family practice and. At this level, children can begin to view the body as a system, in which parts do things for other parts . Can you think of two body systems that work together?.

Fibers, undigestible material, bile and loads of bacteria travel through the large intestines and out through the colon and rectum. The kidneys filter out wastes from the blood to form urine, which flows down the ureters and enters the urinary bladder.

The bladder collects the urine and releases when full, out through a the urethra. Both digestive and excretory systems are regulated with input from the nervous system and endocrine system, and the cardiovascular system is inextricably linked with bowel and kidney function on multiple levels.

Endocrine and Immune Systems The endocrine system system uses hormones, or chemical messengers across distances to effect target organs and tissues. Hormones are typically produced by a gland such as the pituitary, thyroid or gonads, and released into the bloodstream.

The pituitary is is considered a master gland, since it governs the release of hormones by other glands. Unlike the nervous system, there is no physical "wiring" with neurons, however, and the hormones reach their target via the blood stream, where they exert their effect.

The endocrine and nervous system may work together on the same organ, and each may influence the actions of the other system. The endocrine system largely governs many processes related to reproduction and sexual maturity, as well.

The immune system is a network of cells, tissues and organs that work together to attack pathogens that try to invade your body. Bacteria, parasites and fungi that may cause infection meet a system of immune soldiers, including T-lymphocytes, macrophages and neutrophils.

With time, the immune system's B-lymphocytes can produce antibodies against a new unknown invader. Key points Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive. The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.

The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food. The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.

Introduction If you were a single-celled organism and you lived in a nutrient-rich place, staying alive would be pretty straightforward.

For instance, if you were an amoeba living in a pond, you could absorb nutrients straight from your environment. The oxygen you would need for metabolism could diffuse in across your cell membrane, and carbon dioxide and other wastes could diffuse out. When the time came to reproduce, you could just divide yourself in two! How, then, does the body nourish its cells and keep itself running?

Let's take a closer look at how the organization of your amazing body makes this possible. Multicellular organisms need specialized systems Most cells in large multicellular organisms don't directly exchange substances like nutrients and wastes with the external environment, instead, they are surrounded by an internal environment of extracellular fluid—literally, fluid outside of cells. The cells get oxygen and nutrients from this extracellular fluid and release waste products into it.

Humans and other complex organisms have specialized systems that maintain the internal environment, keeping it steady and able to provide for the needs of the cells.

Different systems of the body carry out different functions. For example, your digestive system is responsible for taking in and processing food, while your respiratory system—working with your circulatory system—is responsible for taking up oxygen and getting rid of carbon dioxide. The muscular and skeletal systems are crucial for movement; the reproductive system handles reproduction; and the excretory system gets rid of metabolic waste. Because of their specialization, these different systems are dependent on each other.

The cells that make up the digestive, muscular, skeletal, reproductive, and excretory systems all need oxygen from the respiratory system to function, and the cells of the respiratory system—as well as all the other systems—need nutrients and must get rid of metabolic wastes.

Body Systems & How They Work Together

All the systems of the body work together to keep an organism up and running. Overview of body organization All living organisms are made up of one or more cells.

Introduction To Anatomy Physiology: Organ Systems (01:04)

Unicellular organisms, like amoebas, consist of only a single cell. Multicellular organisms, like people, are made up of many cells.

Tissues, organs, & organ systems

Cells are considered the fundamental units of life. The cells in complex multicellular organisms like people are organized into tissues, groups of similar cells that work together on a specific task. Organs are structures made up of two or more tissues organized to carry out a particular function, and groups of organs with related functions make up the different organ systems. At each level of organization—cells, tissues, organs, and organ systems—structure is closely related to function.

Through the use of an online interactive activity, children learn about the concept of separate components working together to build a body system. In addition, this lesson focuses on activities to help students learn that body systems work together to build the functioning human body. In order to be able to do this lesson, students should understand that most items are composed of different parts and that an item may not work if its parts are missing.

Also, they should know that an assembly of parts can perform functions that the single parts cannot perform alone. More specific to the human body, students at this level should realize that the human body has parts that help it seek and take in food when it feels hunger.

They should understand that the brain is the part of the body that enables humans to think and it communicates with the other parts of the body. This prerequisite knowledge should help elementary-school students understand that parts within a system usually influence one another and that a system may not work as well, or at all, if a part is missing, broken or worn out, or misconnected. In addition, they should be able to make correlations about systems in general to systems of the human body.

Specific to the human body, students should understand the following: Benchmarks for Science Literacy, p.
