Gallery Walk: Human Body Systems, Organs, and Functions
Respiratory System
The respiratory system (respitorary) comprises key organs and anatomical structures including the lungs (lungs 3), trachea, nose, and mouth (mout). These components function together to allow atmospheric gases to enter and exit the body.
The primary function of the respiratory system is to take in oxygen, release carbon dioxide () as waste, and distribute oxygen throughout the entire body.
Digestive System
The digestive system consists of key organs including the stomach, liver, esophagus (asapagash), intestines (intestanse), and pancreas (Ponches). Each organ performs distinct tasks within the digestive tract to process consumed material.
The essential function of the digestive system is to break down food mechanically and chemically, enabling the body to extract necessary nutrients for cellular processes and energy.
Circulatory System
The circulatory system includes the heart, arteries (artieries), veins, and blood cellular elements such as red blood cells and white blood cells (red+white blood cells). These components create an interconnected vascular network throughout the organism.
The main function of the circulatory system is to pump blood and oxygen continuously around the body to sustain tissue function and bodily life.
Nervous System
The nervous system (NONOUS) is composed of three main structures: the brain, spinal cord, and peripheral nerves. Together, these form the primary communication and command center for the body.
The central function of the nervous system is to send electrical and chemical signals from the brain down through the spinal cord and throughout the nerve network to regulate physiological processes and movement.
Muscular System
The muscular system consists of skeletal muscles (musscles) and tendons (Tendoms). Tendons attach muscle tissues directly to bones to facilitate torque and movement.
The core function of the muscular system is to assist directly with bodily movement, posture, and physical structure.
Skeletal System
The skeletal system is made up of bones, joints (joints/points), and ligaments (ciganents). Bones supply a rigid frame, joints allow articulation, and ligaments connect bones to other bones.
The principal functions of the skeletal system are to provide foundational structure and support for the body, as well as to surround and protect vital internal organs from physical damage.
Immune System
The immune system relies on key specialized structures and cells, including white blood cells, the spleen (SPRen), and bone marrow. These cellular components constantly monitor bodily tissues.
The critical function of the immune system is to fight off infections by identifying and destroying foreign threats, including bacteria, viruses, and other disease-causing pathogens.
Excretory System
The excretory system contains key renal structures including the kidneys, bladder, and ureters. These structures continuously process fluid within the body.
The main function of the excretory system is to filter waste products from the blood and eliminate them from the body in the form of liquid urine waste.
