Bodily Systems

Question 1

What are the Systems of the Body.

Answer 1

The Respiratory System
The Circulatory System
The Nervous System
The Endocrine System
The Gastrointestinal System
The Urinary/Renal System
The Reproductive System
The Integumentary(Skin) System

Question 2

What does the Respiratory System do.

Answer 2

Numerus Organs that take in oxygen and expel waste products.

consists of:

Upper Airway
Lower Airway
Diaphragm

Question 3

What is the Upper Airway

Answer 3

The Nose
The Mouth
The Nasopharynx
The Oropharynx
The Larynx (Voice Box)
Epiglottis(valve that closes over Trachea during swallowing)

Question 4

What is the Lower Airway

Answer 4

The Trachea (tube that connects the pharynx to the bronchi)
The Bronchi (tubes that lead to the lungs)
The Alveoli (tiny air sacs where oxygen and carbon dioxide are exchanged)
The Larynx(Voice Box)

Question 5

What is the Circulatory System and what is its main structure.

Answer 5

The system that carries oxygen and nutrients to all of the cells of the body. The main structure of the Circulatory system is the heart.

Question 6

What are the four chambers of the heart and their functions

Answer 6

Right Atrium: Fills with oxygen-poor blood which is then pumped to the right ventricle

Right Ventricle:Fills with oxygen poor blood from the right Atrium, The right ventricle then contracts to pump the oxygen-poor blood through the pulmonary arteries to the lungs to be oxygenated

Left Atrium: Fills with oxygen-rich blood coming from the lungs, the Atrium then contracts to send blood to the left Ventricle.

Left Ventricle: The left ventricle fills with oxygen-rich blood, and then contracts in order to send out the oxygen-rich blood though the Aorta, throughout the body

Question 7

how does the heart pump, and what are the nodes it uses to do so.

Answer 7

The heart pumps through electricity The nodes are:

The Sinoatrial Node: The Pacemaker of the heart, and it passes electrical signal to the Atria, causing them to contract.

The Atrioventricular Node: the signal that passed though the Atria then passes through this, which is then passes through the >

Bundle of His>

Purkinje Fibers.

all of this causes the Ventricles to contract

Question 8

What are the parts of the nervous system.

Answer 8

The Central Nervous System

The Peripheral Nervous system

Question 9

What does the Central Nervous System consist of.

Answer 9

The Brain, and the spinal chord

Question 10

What are the parts of the Peripheral Nervous System and what do they do.

Answer 10

Sensory Neurons and Motor Neurons

Sensory: Sends sensory information from the body to the CNS
Motor: Relays commands coming from the CNS to the muscles of the body.

Question 11

how is the Peripheral Nervous System divided.

Answer 11

Somatic(Voluntary)

Somatic: divided into the Sympathetic and Parasympathetic systems.

• sympathetic:Controls Fight or Flight Response
• Parasympathetic: Returns the body back to normal after the need for the Fight or Flight Response is over.

Autonomic(Involuntary)
