1. Answer the following questions:-
a. What is the function of skeletal system?
b. Which body system deals with breathing?
c. What is the function of blood?
d. Write the names of organs that constitute digestive system.
e. What do you understand by voluntary muscles?
f. What does nervous system consist of?
g. Briefly explain the function of heart and brain.
Answers
The skeletal system has many different functions that are necessary for human survival. Some of the functions, such as supporting the body, are relatively obvious. Other functions are less obvious but no less important. For example, three tiny bones (hammer, anvil, and stirrup) inside the middle ear transfer sound waves into the inner ear.
b. The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system.
c.Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues. forming blood clots to prevent excess blood loss. carrying cells and antibodies that fight infection.
d.The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system. The small intestine has three parts. The first part is called the duodenum.
e.Voluntary means done out of free will or by choice. Voluntary muscles are also often called skeletal muscles (because all of the muscles attached to the skeleton are voluntary muscles) or striated muscles (because the muscle fibers make them look striated, or stripy).
f.The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
G. The heart is the main organ in the circulatory system, the structure primarily responsible for delivering the circulation of blood and transportation of nutrients in all parts of the body. This continuous task uplifts the role of the heart as a vital organ whose normal operation is constantly required. BRAIN. - assembles the messages in a way that has meaning for us, and can store that information in our memory. The brain controls our thoughts, memory and speech, movement of the arms and legs, and the function of many organs within our body.
MARK ME AS BRAINLIST PLEASE
Answer:
a)The major functions of the skeletal system are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and blood cell formation
b)The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system
c)It brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Blood also fights infections, and carries hormones around the body.
d)The major parts of the digestive system:
Buccal cavity,
Salivary glands,
Esophagus,
Stomach,
Small Intestine,
Large Intestine,
Rectum,
Anas.
(Accessory digestive organs: liver, gallbladder, pancreas.)
e)Voluntary means done out of free will or by choice. Voluntary muscles are also often called skeletal muscles because all of the muscles attached to the skeleton are voluntary muscles or striated muscles because the muscle fibers make them look striated, or stripy.
f)The nervous system has two main parts: The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
g) Heart:- The heart is a muscular organ in most animals, which pumps blood through the blood vessels of the circulatory system. The pumped blood carries oxygen and nutrients to the body, while carrying metabolic waste such as carbon dioxide to the lungs.
Brain:- The brain is an organ that's made up of a large mass of nerve tissue that's protected within the skull. It plays a role in just about every major body system. Some of its main functions include: processing sensory information.
