Science Flashcards: Cells and Systems

Question 1

Name all of the organ systems and explain the organs that belong in each system:

Answer 1

Respiratory system
Organs- Nose, Mouth, Trachea, Diaphragm, bronchi, bronchioles, lungs.

Excretory system
Organs- Kidneys, bladder, lungs, skin, liver.

Muscular system
Organs- muscles, tendons

Nervous system
Organ- Brain, spinal cord, nerves, eyes, ears, hands, nose, ect. any other sensing organs.

Digestive system
Organs- Salivary, glands, mouth, esophagus, stomach, liver, pancreas, gall bladder, small intestine, large intestine

Question 2

What is the function of the Respiratory system?

Answer 2

Function- To transport outside air to the blood and transport carbon dioxide from the blood to the outside air.

Question 3

What is the function of the Excretory system?

Answer 3

Function- Remove chemical and gaseous waste from the blood

Question 4

What is the function of the Muscular system?

Answer 4

Function- Move bones, move organs that contain muscle tissue ( the heart and stomach)

Question 5

What is the function of the nervous system?

Answer 5

Function- Coordinate and control the actions of all organs and organ systems

Question 6

What is the function of the digestive system?

Answer 6

Function- Break down food pieces into smaller pieces to be absorbed and moved throughout the body

Question 7

What is the order of the digestive system?

Answer 7

1. Chew; let saliva break down food
2. food goes down esophagus.
3. stomach.
4. gall bladder
5. small intestine.
6. large intestine.
7. rectum.
8. And lastly to your anus.

Question 8

What is the order of the Respiratory system?

Answer 8

1.Nose
2. mouth
3. Trachea
4. bronchi
5. Bronchioles
6. Alvioles

Question 9

What is the order of the circulatory system?

Answer 9

carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.
-Heart
- Arteries
- Arterioles
- Capillaries
- Venules
- Veins

Question 10

What are the types of digestions?

Answer 10

-Mechanical digestion
(The physical break-down of food)
Takes place: Mouth, esophagus, stomach, small intestine.

-Chemical digestion
(Breakdown of large particles by enzymes)
Takes place: Mouth, stomach, small intestine

Question 11

*How do the small intestines function?

Answer 11

The small intestines break down food and turn them into juices to the body so the nutrients can be used.

Question 12

What are the effects of smoking?

Answer 12

-Hard to breath
-Asthma
-Lung cancer
-Chest pain

Question 13

Know about the scientists we talked about:

Question 14

What is dialysis?

Answer 14

The removal of waste products from the blood using a machine that functions as a kidney.

Question 15

What are the diffident types of blood vessels and their functions?

Answer 15

Blood vessels are designed to carry/ transport blood.
Types of blood vessels and their functions:

Arteries- Carry blood AWAY from the HEART
(arteries are thick and muscular)

Veins- Carry blood TOWARDS the HEART

Capillaries- Tiny blood vessels that CONNECT the ARTERIES TO the VEINS
(capillaries are thin)

Question 16

In the nervous system, what do nerves do?

Answer 16

They carry signals or messages from the brain and spinal cord to different parts of the body.

Question 17

In the nervous system, what do axons do?

Answer 17

-Is a tail-like extension of the cell body
-sends electrical impulses to the next cell

Question 18

How does the small intestine function?

Answer 18

-partly digested food comes from the stomach
-Once it reaches the small intestine it will break down the food even further using enzymes
- The small intestine absorbs the majority of the nutrients which then gets sent to the blood stream.
(The small intestine also uses chemical digestion when breaking down the food further)
