Juan Diaz Human Body Systems
Respiratory System
Nervous System
Muscular System
Circulatory System
Levels of Organization
From lowest level to highest level: Cells, Tissues, Organs, Organ Systems, Organisms.
Function: Carry messages to and from the brain and spinal cord to various parts of the body.
Function: To inhale oxygen and exhale carbon dioxide.
Function: To move blood through the body leadng to transporting nutrients and oxygen to the cells of the body and removing wastes.
Endocrine System
Function: Made up of glands that produce and secrete hormones that regulate the activity of cells or organs.
Organs/Parts: Lungs, Trachea, Bronchi and Bronchial tubes, Larynx and Pharynx
Organs/Parts: Heart, blood, blood vessels
Parts: Brain, Nerves, Spinal Cord
Parts:hypothalamus, pineal gland, pituitary gland, thyroid gland, parathyroid glands, thymus, adrenal glands, and pancreas.
Functions of parts: Lungs: take in carbon dioxide and exhale air/oxygen, Trachea: Airway to your moth and lungs, Bronchi: distributes air throughout the lungs, bronchial tubes, let air in and out of your lungs, Larynx: voice box that lets you breath, swallow, and talk, Pharynx: is the throat and carries air, food and fluids from the nose and mouth. This system connects with the circulatory system.
Functions of parts: Pancreas: sends out hormones that control the amount of sugar in your bloodstream, pineal gland: receive info about state of light-dark,Pituitary gland: regulates growth, metabolism, etc, Thyroid gland: major role in metabolism growth, Adrenal glands, makes fluid hormones, Thymus: body's defense mechanism in the endocrine system. This system works with the nervous system.
Function of parts: Spinal cord: pathway for messages sent by the brain to the body and from the body to the brain, Brain: is the signal sender and receiver, nerves also have signals that go to the brain and throughout the body. This system works with the endocrine system.
Immune System
Function: The body's defense against disease causing organisms, malfunctioning cells, and foreign particles.
Parts: White blood cells, adaptive and innate systems.
Digestive System
Function: Breakdown food into it's nutrients, absorb them, and then waste in excreted
Urinary System
Functions of parts: Rectum: expels waste from the digestive system, Small and Large intestine: tubes that lead waste to the rectum, Stomach: chemically dissolves food that comes down from the esophagus, Mouth: chews food with saliva and makes the food into small pieces, Esophagus: pathway for food to go to stomach, Pancreas: makes enzymes, Gallbladder: stores and concentrates bile from liver, Liver: creates bile. This system connects with the circulatory and urinary systems.
Parts: Mouth, Esophagus, Liver, Stomach, Gall Bladder, Pancreas, Small and Large Intestine, and Rectum
Function of Parts: Innate immune system:The second line of defense against non-self pathogens, Adaptive immune system: attack and destroy foreign invaders and are able to prevent disease in the future by remembering what those substances look like and mounting a new immune response, White blood cells: help fight off diseases.
Functions of parts: Heart: continues pumping blood while you sleep/pumps blood, Blood: Keeps you alive and supports all body systems/connects all body systems (other than skeletal), Blood vessels: passageways for blood. This system connects with the respiratory and digestive systems.
Reproductive System
Function: To sexually reproduce/produces egg and sperm cells
Parts: Ovaries, Penis, Testes, Sperm, Prostates, Vagina, Fallopian tubes, cervix, uterus
Function of parts: Ovaries: where the egg is formed and the female hormones estrogen and progesterone are made, Penis: where sperm comes from, Testes: where sperm is stored, Sperm: is the thing that goes into the egg to form an embryo, Prostates: produce the fluid that is good and transports sperm, Vagina: tube leading to uterus chamber, Fallopian tubes: connect ovaries to uterus, Cervix: allow sperm to go between uterus and vagina, Uterus: the chamber where the egg/embryo forms and is stored until baby is fully formed. . This system works with the circulatory system.
Function: Movement and aids digestion. Parts: Cardiac muscles, skeleton muscles, smooth muscles, tendon. Functions of parts: Tendon: move bone of skeletal system, Smooth:maintain blood pressure and flow, Cardiac: delivers oxygen, nutrients, hormones, and other important substances to the body, Skeletal:gives the body its shape, allows movement, makes blood cells, provides protection and stores minerals. The muscular system also goes with the skeletal system because the skeletal system protects this system and also connects to this system with the tendons. It also goes with any system with muscles because all the systems with muscles have these different types of muscles, such as the digestive, nervous, circulatory, etc.
Function: Hold urine until ready for excretion, create urine from waste materials and filter waste from blood. Parts: Ureters, Kidney, Uretha, Urine, Bladder. Functions of parts: Urine: liquid waste filtered from blood, Kidney: filter waste from blood, Urethra: empties urine from the bladder, Ureters: carry urine from kidney(s) to bladder, Bladder: holds urine. This system connects with the digestive system.
Skeletal System
Function(s): To support the body, help with movement, protect the body, make blood cells, and store calcium. Parts: bones and connective tissue, including cartilage and ligaments. Functions of parts: Bones: Protect your body, Connective Tissue: connect with the muscular system. The skeletal system also goes with the muscular and digestive system because it protects both.
