Name one body system that has to do with health?
Our body systems help us stay healthy and functioning. They include the circulatory, digestive, skeletal, nervous, and respiratory systems. Each system has a specific job that helps keep us healthy. For example, the circulatory system carries oxygen and nutrients to cells and removes wastes. Taking care of our body systems is important. Eat a balanced diet, get plenty of rest, and stay active to help keep your body systems healthy.
Body Systems Health
Heart, Blood vessels, Blood Blood vessels: arteries, veins and capillaries Arteries carry oxygen rich blood away from the heart to the organs Veins carry blood back to the heart
What are the major organs of the circulatory system?
Lungs, Trachea, Larynx/Pharynx, Mouth and Nose Responsible for removing waste (carbon dioxide) Puts oxygen back into blood stream
The respiratory system is the only system in the human body that has direct contact with the environment. The average person takes about 20,000 breaths a day. The right lung is slightly larger than the left.
Did you know?
The nervous system is a complex network of cells that sends messages throughout the body. It is responsible for sensing, interpreting, and responding to information from the environment. It is made up of the brain, spinal cord, and nerves that extend throughout the body.
Nervous System: The Body's Information Highway
The Nervous System is a complex network of nerves and cells that carry messages to and from the brain and spinal cord to various parts of the body. It controls the body’s responses to different situations and helps to coordinate activities. Neurons are cells that make up the nervous system. They are responsible for carrying messages between the brain and the body. The messages travel along nerve pathways, which are like roads that lead from one neuron to the next. The Central Nervous System (CNS) is made up of the brain and the spinal cord. It is responsible for processing information and communicating with the body. The Peripheral Nervous System (PNS) is made up of nerves that branch off from the spinal cord and connect to the rest of the body.
The digestive system is made up of organs that break down food into nutrients It is composed of the mouth, esophagus, stomach, small intestine, large intestine, and rectum The liver, gallbladder, and pancreas are also part of the digestive system
The Digestive System
The skeletal system is made up of bones, ligaments, and tendons that help us move and protect vital organs. It also produces blood cells and stores minerals, including calcium and phosphorus. Caring for our skeletal system is important for life-long health and mobility.
The Skeletal System
Skeletal System: The skeleton is the body’s framework of bones, cartilage, and connective tissue that supports and protects the body’s organs and anchors its muscles. The 206 bones of the skeleton form at different times during a person’s life and fuse together as they mature. Joints: Joints are points at which two or more bones meet. They provide movement and flexibility to the skeleton and act as shock absorbers. Joints are classified according to their range of motion, such as hinge, ball-and-socket, and pivot. Muscles: Muscles are body tissues that contract when stimulated, producing movement. Muscles attach to the skeleton at specific points, such as tendons, and are essential for body movement. Without muscles, the body would be unable to move.
The human skeletal system is made up of 206 bones, which is slightly different from other mammals. The smallest bone in the human body is the stapes, which is located in the ear. The bones in the human body contain about 25 percent of the body’s total amount of water.
