Human Body Systems 1
The body system that is responsible for breaking down your food into usable nutrients.
The digestive system
The digestive system
The body system responsible for bringing in oxygen and removing carbon dioxide.
The respiratory system
The body system that coordinates the body's actions and transmits signals to and from different parts of the body.
The nervous system
The body system that distributes oxygenated blood through the body.
The circulatory system
Where do humans acquire energy
Food
What is considered the smallest level of organization in a living organism?
Cell
Explain what your pulse is?
Your pulse, also known as your heart rate, is the number of times your heart beats per minute (bpm).
The brain is responsible for coordinating movement and balance?
True
List the levels of organization in the human body from simplest to most complex, starting with the cell and ending with organ system.
cell --> tissue --> organ --> organ system
The two systems that must work together for the body to move.
Skeletal and Muscular
What is composed of Tissues?
Organs
The products that must be removed from the human body are called?
Waste
What is the meaning of homeostasis?
Homeostasis is the body's ability to maintain a stable internal environment, even when external conditions change. It's a state of balance among the body's systems that allows the body to function properly and survive.
Explain the structures and functions of the muscular system.
The muscular system is composed of specialized cells called muscle fibers, which contract to produce movement.
Explain the parts and functions of the Central and Peripheral nervous systems.
The Central Nervous System (CNS) consists of the brain and spinal cord, acting as the body's processing center, while the Peripheral Nervous System (PNS) comprises nerves branching out from the CNS to reach the rest of the body. Essentially, the CNS "decides" actions, and the PNS carries out those commands by sending signals to the appropriate body parts.
True or false: Veins are blood vessels that carry oxygenated blood from the body.
False: arteries carry oxygen rich blood.
True or false: The central nervous system consists of the brain and spinal cord.
True
Explain the main body system that fights off bacteria and viruses?
The immune system is a complex network of cells, organs, and proteins that work together to identify and neutralize harmful substances like bacteria and viruses, protecting the body from infection.
The stomach is the organ in the digestive system where nutrients we eat are absorbed into the blood stream.
False: small intestines
What are the 2 main functions of the circulatory system?
1. Transports oxygen to cells
2. Removes carbon dioxide from cells
What is the main functions of the respiratory system?
1. The exchange of oxygen and carbon dioxide between the blood and the cells of the body
What are the 2 main functions of the digestive system?
1. Digest food into usable nutrients
2. Absorb nutrients into the blood stream
Explain the important functions of the Excretory system.
The primary function of the excretory system is to remove waste products, excess water, and toxins from the body, primarily through urine production by the kidneys, and sweat.
Name the two parts of the nervous system.
Central Nervous System (CNS) and Peripheral Nervous System (PNS)
