Mind Stretcher 206 Adult’s have ________ bones and approximately _______ muscles in their body. Which tissue contracts and relaxes to produce movement? -connective, muscular, epithelial or nervous 650

Question to Ponder… What is a system? a set of connected things or parts forming a complex whole, in particular. How does this definition relate to our body systems?

Learning Target Today I am learning about the body systems because they keep me alive by working together.

Human Body Systems Review Structures, Functions, and Interactions

How does your body move?

Skeletal Structures: bones, cartilage, joints, marrow Functions: provides shape and support, enables you to move, protects your internal organs Interactions: * bones make your red blood cells (cardiovascular/circulatory) * helps you move (muscular)

Skeletal

Muscular Structures: skeletal muscle, smooth muscle, and cardiac muscle Functions: Involuntary muscles for breathing and digesting food; Voluntary muscles are under your control (movement) Interactions: All systems b/c all of your organs are made of muscle

Muscular

How does your body get nutrients?

Digestive

Digestive Structures: Mouth, esophagus, liver, stomach, gallbladder, pancreas, large intestines, small intestines, rectum Function: breaks down food into molecules the body can use, and eliminates unused food. Interactions: Uses the circulatory system to take food to the individual cells, forms the end of the excretory system to expel solid waste.

Digestive System (Lower part) Structures: Large Intestines, rectum, anus Functions: Material that cannot be absorbed into the blood stream is compacted in the large intestines for elimination. Interactions: The large intestine absorbs water into the cardiovascular system for use throughout the body.

Digestive System (Lower Part)

How does your body provide control and coordination How does your body provide control and coordination? How does it communicate among its systems?

Nervous Structures: brain, spinal column, nerves. Functions: sends electrical messages to detect & interpret info from inside and outside the body; control center Interactions: Tells muscles to contract (voluntary), tells heart to pump (involuntary)

Nervous

Endocrine Organs: glands such as hypothalamus, thyroid, ovaries, testes Functions: Controls body functions by using chemical messages from glands Interactions: Sends growth hormones to skeletal system, releases adrenaline into the blood stream to stimulate the muscles into action.

Endocrine

How does your body protect itself from disease?

Lymphatic System Organs: Tonsil, Spleen, Thymus, Lymph Nodes Function: returns leaked fluids to blood vessels and helps get rid of bacteria and viruses. Interactions: White blood cells made in the bones grow into T cells in the thymus.

Lymphatic System

Integumentary System Organs: Skin, Hair, Nails Functions: Protects; keeps water in & foreign particles out; allows you touch; regulates temperature; gets rid of wastes Interactions: Works with the nervous system to keep you aware of your surroundings.

Integumentary System

How do our cells get the oxygen they need How do our cells get the oxygen they need? How do they get rid of carbon dioxide?

Respiratory Structures: Nose, Trachea (Wind Pipe), Lungs: Bronchi/Bronchioles, Alveoli Function: Moves oxygen into the body and removes carbon dioxide and water vapor from the body. Interactions: Circulatory system carries oxygen to the cells and carbon dioxide away.

Respiratory

Ted Ed Video- What do the lungs do?

Circulatory or Cardiovascular Structures: Heart, blood vessels Functions: Heart pumps blood through all blood vessels. Interactions: Highway system of the body, carries food (digestive) and oxygen (respiratory) to the cells and carries waste away.

Cardiovascular

Ted Ed Video- How does the heart pump blood?

How does your body EXCRETE waste?

Urinary Structures: kidney, urinary bladder, urethra Functions: Blood is filtered through the kidneys to remove cell/molecular waste. Waste is stored in the bladder and eliminated as urine. Interactions: Cleans waste from the circulatory system.

Urinary

Ted Ed Video- What do they kidneys do?

Respiratory Structures: Nose, Trachea (Wind Pipe), Lungs: Bronchi/Bronchioles, Alveoli Function: Removes carbon dioxide and water vapor from the body. Nose and windpipe filters out dust and particles. Interactions: Circulatory system carries carbon dioxide away.

Integumentary System Organs: Skin, Hair, Nails Functions: gets rid of wastes through sweat glands in the skin. Interactions: Works with the circulatory system which brings the wastes to the skin.

How does your body reproduce?

Reproductive Structures: Testes, ovaries, and uterus Function: Create a new living individual Interactions: The endocrine system regulates the hormones necessary for sexual maturity and reproduction.

Mind Stretcher Match the system to its function: Digestive, Endocrine, Nervous, Muscular, Skeletal System Function: Glands to secrete hormones/adrenaline, etc. Enable movement Give shape and support; protect inner organs Break down food for nutrients Send electrical messages; Control center Endocrine Muscular Skeletal Digestive Nervous

Mind Stretcher Which systems are responsible for removing wastes from the body? Urinary, digestive and excretory Urinary, muscular, skeletal Urinary, nervous, endocrine Urinary, lymphatic, nervous
