Unit 3 - Homeostasis in Human Body Systems

Which function of the human blood includes the other three choices?

• Transporting nutrients
• Transporting oxygen
• Maintaining homeostasis
• Collecting wastes

Which system is correctly paired with its function?

• Immune system-- intake and distribution of oxygen to all cells of the body.
• Excretory system-- remove potentially dangerous materials from the body. 
• Digestive system-- transport energy-rich molecules to cells.
• Circulatory system-- produce building blocks of complex compounds.

The cytoplasm in a cell carries out a function similar to a function of which human system?

• Respiratory system
• Reproductive system
• Circulatory system
• Nervous system

In order for the human body to maintain homeostasis, the breakdown of glucose to release energy must be followed by the...

• production of oxygen
• division of the cell
• removal of wastes
• production of receptor molecules

The main function of the human digestive system is to...

• rid the body of cellular waste materials 
• process organic molecules so they can enter cells 
• break down glucose in order to release energy
• change amino acids into proteins and carbohydrates

In humans, the organ that most directly regulates the concentration of water in the blood is the...

• Heart 
• Liver
• Pancreas
• Kidney 

Which statement best describes the human respiratory system?

• It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs. 
• Each cell of the human body is in direct contact with the external environment, and gas exchange occurs by diffusion.
• The external body surface is kept moist to allow for gas exchange. 
• Gases diffuse across membranes on both the external and internal surfaces of the body.

How does the circulatory system and the skeletal system work together?

• the circulatory system makes cells while the skeletal system transports the cells where the need to go
• the skeletal system makes cells while the circulatory system transports them where the need to go
• The circulatory system produces energy for the body and the skeletal system makes cells for the body
• The skeletal system digests food and the circulatory system brings air into the body

How does the digestive system work with all other systems?

• The digestvie system transports blood to all the other systems
• The digestive system puts oxygen into the body
• The digestive system gives the body energy and nutrients
• The digestive system allows the body to move

How does the muscular system and the skeletal system work together?

• The muscular system allows the body to stand up while the skeletal system allows the body to move
• The muscular system allows the body to move and the skeletal system gives the body a structure 
• The muscular system gives the body nutrients while the skeletal system gives the body blood
• The skeletal system makes cells whilte the muscular system eats them.
