Human Body Systems, Chapter 3

Skeletal system

206 bones, protects organs, produces blood cells

Circulatory system

Transports oxygen through blood

Digestive system

Breaks down food, absorbs nutrients

What is the Endocrine system made up of and what does it do?

Made up of glands that regulate hormones and carries messages to other parts of the body. These glands regulate mood, growth/development, metabolism and reproduction.

What organs are in the Excretory system and what is the function.

Made up of the kidneys, ureters, bladder, and urethra. It filters the blood and removes liquid waste/extra water from the body (urine, sweat)

What is the Integumentary system and what is it’s function.

Outer shell of an animal body, protects and maintains water

What does the Lymphatic/Immune system include and what does it do?

Includes lymph nodes, helps with immune response

What are the three types of muscles in the Muscular system?

Includes skeletal, smooth, and cardiac muscles

What does the Nervous system do?

This system sends and receives nerve messages throughout the body.

What does the Reproductive system do?

Allows for reproduction

What does the Respiratory system do?

Facilitates intake and exhaling of oxygen

What is a Tissue?

Group of cells with the same function

What are the two plant organ systems?

Root system (below ground) and shoot system (made up of anything above ground)

What is an Organ?

Group of tissues working together

What is the definition of an Organ System?

Organ systems are made up of more than one organ and perform one or more specific function in the body. The organs in an organ system work together.

What is the definition of an Organism?

Group of systems working together

What do Connective tissues do?

Supports and connects body parts

What do Nervous tissues do?

Receives and sends nerve impulses so that the system can control movements.

How do Muscle tissues move?

Contracts and relaxes for movement

What is another way to say Epithelial tissues?

Lining tissues

What are organs made of?

Made up of tissues that work together to perform a specific task.

What are the 11 human organ systems?

Skeletal, circulatory, digestive, endocrine, excretory, integumentary, lymphatic/immune, muscular, nervous, reproductive, respiratory

What are the 3 plant tissues and what is their function?

Protective (prevents water loss and protects plant) , photosynthetic (transforms the Sun's energy into sugar), transport (contain hollow tub like cells that move food and water through the plant)

What is the shoot system of a plant?

Above-ground part of a plant

What is the root system of a plant?

Below-ground part of a plant

How are lungs and oxygen connected?

Lungs receive oxygen for blood and muscles

How are Buildings and the skeletal system similar?

Both provide structure and shelter

How are Buses and trains and cardiovascular system similar?

Both transport and send things where needed

How are Libraries and nervous system similar?

Both collect and store information

How are the Grocery store and digestive system similar?

Both supply nutrients needed

How are the Police and lymphatic system similar?

Both patrol and protect from harm. The BLANK System patrols the body and ID's substances like bacteria and viruses that can cause disease. It also heals the body when it becomes sick. Police arrest and patrol streets to protect from suspicious people.

What are 5 examples of connective tissues?

Blood, fat, cartilage, tendons, and bone

The spinal cord, brain, and nerves are all made up of BLANK tissues.

Nervous tissue makes up these organs.

What does the epithelial tissue line?

the inside of organs, such as the small intestine in lined by this tissue

What are the 3 types of muscle tissue?

skeletal, cardiac, smooth are the types of tissue.

What is skeletal muscle?

also called striated muscle, it is attached to the skeleton. It is voluntary controlled.

What is cardiac muscle?

The muscle that makes a heart beat. We can't control it (it's involuntary)

What is smooth muscle?

muscle that moves involuntary and without you thinking about it. They keep your eyes focused and help food move through your intestines.

What are the three ORGANS of a plant?

roots, stems, leaves

What is a tumour?

mass of abnormally growing/ cancerous cells

What is paralysis?

the inability to move muscles.

How can the spinal cord cause paralysis?

If the spinal cord is severed below the shoulders, the lower body and legs are paralysed.

If the spinal cord is servered in the neck area, all four limbs can be paralyzed.

When severed nerve impulses from the body are not able to make it to the brain, and vice versa.

How has tech developed to compensate for lack of mobility?

Wheelchairs have been approved, access to building/transportation has been improved as well.

Are viruses living? Why or why not?

Viruses are not living because they can’t make their own energy or divide on their own. They need host cells to reproduce in.

What is the spinal cord?

The body’s spinal cord has cells that transmits nerve impulses from the senses to the brain and carries impulses from the brain to muscles so that they can move. (communication link from brain to body)

What are hormones?

Hormones are chemicals that regulate every bodily function.

List 3 glands and their function:

Glands such as the pituitary, thyroid, and pancreas all produce hormones that carry messages to other parts of the body.

What does the nervous system control?

It also controls behaviour, movement, and processes such as digestion and circulation.
