Human body, Respiratory system, Reproductive system (male and female) -…
Human body
Digestive system
Mouth: Salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus.
esophagus: Transports food entering the mouth through the throat and into the stomach.
stomach: digests food
Small intestine: helps to further digest food coming from the stomach.
Large intestine: absorbs water and changes the waste from liquid into stool.
Rectum: stores stool until it pushes stool out of your anus during a bowel movement.
Anus: Opening where stool leaves the body.
Salivary glands: participate in the digestion of triglycerides and starches by secreting lipases and amylases.
Pancreas: makes pancreatic juices called enzymes.
Liver: process the nutrients absorbed from the small intestine.
Gall bladder: stores and concentrates bile from the liver.
Functions: Takes in food, Digests food into smaller molecules and absorbs nutrients and Removes undigestable food from the body also known as feces/human waste.
Works with: Circulatory, Muscular and Nervous systems.
Nervous system
Brain:controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body.
Spinal cord: the pathway for messages sent by the brain to the body and from the body to the brain.
Nerves: carry electrical impulses between your brain and the rest of your body.
Neurons: information messengers.
hypothalamus: helps manage your body temperature, hunger and thirst, mood, sex drive, blood pressure and sleep.
Function: Gathers and interprets information, Responds to information and helps maintain homeostasis
Function: Control center of all other systems. Also the hypothalamus maintains homeostasis by working with all the systems.
Muscular system
Tendons: to move the bone or structure.
Skeletal muscle: contract to produce movement, sustain body posture and position, maintain body temperature, store nutrients, and stabilize joints.
Cardiac muscle: responsible for the contractility of the heart and, therefore, the pumping action.
Smooth muscle: helps with digestion and nutrient collection.
Function: Allows for movement by contracting
Works with: Skeletal, Digestive, Respiratory, Circulatory and Nervous systems
Immune system
T cells:help protect the body from infection and may help fight cancer.
B cells: Produce antibodies
Macrophages: innate immunity, normal tissue development, homeostasis, and repair of damaged tissue.
Skin:
Provides a protective barrier against mechanical, thermal and physical injury and hazardous substances.
Function: Fights of foreign invaders in the body.
Works with: Circulatory, Lymphatic, Skeletal and integumentary systems.
Levels of organization
Cells: Basic unit of life
Tissue: A group of cells that work together to perform a specific function.
Organs: A part of the body that performs a specific function.
Organ system: group of organs that work together to perform one or more functions.
Organisms: Living things made up of one or more cells can be animals or plants as an example
Skeletal system
Bones: Bone provides shape and support for the body, as well as protection for some organs.
Ligaments: hold structures together and keep them stable.
Cartilage: resist compressive forces, enhance bone resilience, and provide support on bony areas where there is a need for flexibility.
Functions: Protects organs, provides shape and support, Stores Materials, Produces blood cells and allows for movement.
Works with:Muscular, Circulatory,immune and respiratory systems
Endocrine system
Hypothalamus: helps manage your body temperature, hunger and thirst, mood, blood pressure and sleep.
Pituitary Glands: produces a number of hormones.
Thyroid Glands: control the speed of your metabolism.
Thymus Glands: makes and trains special white blood cells called T-cells.
Adrenal Glands: produce hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions.
Pancreas: helps your body break down food, control your blood sugar, tell your stomach when to empty, and more.
Ovaries: Produce eggs
Testes: Produce sperm
Function: Regulates body activities using hormones. Slow response long lasting.
Works with: Circulatory, Nervous, Reproductive and Skeletal systems.
Urinary/Excretory system/s
Kidneys: getting rid of waste products, drugs, and toxins through our urine.
Ureters: carry urine from the kidneys to the bladder.
Bladder: a reservoir and active excretory organ for urine
Urethra: empties urine from the bladder.
Lungs: excrete some waste products, such as carbon dioxide and water.
Skin-sweat glands: clearing excess micronutrients, metabolic waste, and toxicants from the body.
Liver: regulates most chemical levels in the blood and excretes a product called bile.
Function: Removes waste products from cellular metabolism and it also is able to filter blood.
Works with: Circulatory, Lungs from respiratory system and integumentary systems.
Respiratory system
Lungs: the process of gas exchange called respiration (or breathing).
Alveoli: where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.
Bronchioles: carry air into your lungs.
Bronchi: carry air to and from your lungs
Trachea: carry air in and out of your lungs.
Nose: allows air to enter your body, then filters debris and warms and moistens the air.
Function: Takes in oxygen and removes carbon dioxide and water
Works with: Circulatory, excretory,Nervous and Muscular systems
Reproductive system (male and female)
Female Reproductive system major organ (Ovaries): Produce eggs.
Male Reproductive system major organ (Testes): Produce sperm
Function: Allows organisms reproduce which prevents their species from become extinct.
Works with: Endocrine and Muscular systems.
