How Well Do YOU Know the Body's Systems?
- Which body system contains the organ which has the most calcium?
B. Skeletal System The skeletal system’s bones have the most calcium.
- Which two systems work together to make the body move?
D. Muscular and Skeletal Systems
The two systems work together to make the body move. Skeletal muscles pull on bones to produce movement. Strands of strong connective tissues connect your skeletal muscles to your bones. These strands are known as tendons. When a muscle that connects two bones gets shorter, the bones are pulled closer to each other. This process produces movement.
- What percent of your body weight does the skeletal system make up?
E. 20%
All the bones, cartilage, ligaments, joints, and tendons add up to about 20% of your weight.
- What are arteries?
A. Vessels that carry blood away from the heart.
Each heartbeat pumps blood into your arteries at high pressure. Artery walls stretch and are usually strong enough to stand the pressure.
- What are veins?
B. Vessels that carry blood back to the heart.
A vein is a blood vessel that carries blood back to the heart. As blood travels through veins, valves in the veins keep the blood from flowing backward. When skeletal muscles contract, they squeeze nearby veins and help push blood toward the heart.
- What are the three types of muscular in your body?
E. Smooth muscle, cardiac muscle, and skeletal muscle
Smooth muscles move food through the digestive system, skeletal muscle enables bones to move, and cardiac muscle pumps blood around the body.
- What are the names of the upper and lower chambers of the heart?
Each side of the heart has an upper chamber and a lower chamber. The upper chambers are called atrium and the lower chambers are called ventricle.
- What is the purpose of the circulatory system?
A. The circulatory system brings oxygen and nutrients to every living tissue in your body.
The circulatory system helps maintain homeostasis by performing many functions. These functions include carrying needed substances to cells (like oxygen) and carrying waste products away from cells (like carbon dioxide).
- What is the purpose of the muscular system?
C. The muscular system works together with the skeletal system to help move your body.
The two systems work together to make the body move. Skeletal muscles pull on bones to produce movement. Strands of strong connective tissues connect your skeletal muscles to your bones. These strands are known as tendons. When a muscle that connects two bones gets shorter, the bones are pulled closer to each other. This process produces movement.
- The bones of the body makes a firm structure called the
C. skeleton
The skeleton structures your body. The average adult human skeleton has 206 bones.
- Skeletal muscles are used to…
A. Enable the body to move.
The skeletal muscles, apart of the muscular system, allow you to move your body.
- How many chambers are in the circulatory system?
D. 4
Each side of the heart has an upper chamber and a lower chamber. The upper chambers are called atrium and the lower chambers are called ventricle.
