Three of your body systems have a role  Urethra in excretion. Your integumentary system releases waste products and water when you sweat. Your respiratory system releases carbon dioxide and water when you exhale. Finally, the urinary system contains the organs that remove waste products from your blood.  The kidneys are a pair of organs that constantly clean the blood. Your kidneys filter about 2,000 L of blood each day. Your body holds only 5.6 L of blood, so your blood cycles through your kidneys about 350 times per day!

Then, the nervous system responds to that information as needed.

The immune system is not localized in any one place in your body. It is not controlled by any one organ, such as the brain. Instead, it is a team of individual cells, tissues, and organs that work together to keep you safe from invading pathogens.

Muscular System  Works with the skeletal  All throughout your body system to help your body move  When you want to move, signals travel from your brain to your skeletal muscle cells. The muscle cells then contract, or get shorter.  Protects the tissue that lies Integumentary System beneath your hair, skin and Skin (skin) nails  Skin protects you by keeping water in your body and foreign particles out of your body.  Skin keeps you in touch with the outside world. Nerve endings in your skin let you feel things around you.  Skin helps regulate your body temperature. Small organs in the skin called sweat glands make sweat. Sweat is a salty liquid that flows to the surface of the skin. As sweat evaporates, the skin cools.  Skin helps get rid of wastes. Several kinds of waste chemicals can be removed in sweat.  Skin comes in many colors. Skin color is determined by a chemical called melanin. If a lot of melanin is present, skin is very dark. If little melanin is present, skin is very light. Melanin absorbs ultraviolet light from the sun. So, melanin reduces damage that can lead to skin cancer.

Endocrine System  Your glands send out  Multiple organs chemical messages throughout your body  The endocrine system controls body functions by using chemicals that are made by the endocrine glands. A gland is a group of cells that make special chemicals for your body. Chemical messengers made by the endocrine glands are called hormones. A hormone is a chemical messenger made in one cell or tissue that causes a change in another cell or tissue in another part of the body. Hormones flow through the bloodstream to all parts of the body.

Reproductive System  Male reproductive system: • Ovaries- female produces and delivers • Testes- male  Female reproductive system: produces eggs and nourishes and protects the fetus
