Starter Questions

What is the plural of bronchus?
What is a tissue?
How does oxygen get to your cells?

What is the circulatory system?

The circulatory system is a vital part of the body
"Circulatory" means something that moves in a circle/loop
This process happens continuously throughout the body

What is the circulatory system made of?

The circulatory system consists of the heart and blood vessels
Blood vessels include three types: arteries, veins, and capillaries

Circulatory System Functions

Blood carries oxygen, nutrients, and hormones to cells
Blood carries away waste products

Blood Circulation Details

Oxygen enters the body through breathing, then transferred to the blood in the lungs
Blood carries oxygen and other substances throughout the body
Blood cells act like delivery drivers, dropping off vital substances and collecting waste products

Quick Fire Quiz

Blood cells are like delivery drivers, transporting substances throughout the body.

Circulatory System Video

Information about the circulatory system video is available, but the video itself is not included in the provided text

Double Circulatory System

Humans have a double circulatory system
Blood passes through the heart twice during each circulation loop of the body

The Heart

The heart is central to the circulatory system, functioning as a pump
The heart is a muscle that constantly pumps blood throughout the circulatory system, even at rest
Heart chambers: right/left atrium; right/left ventricle

Parts of the Heart Functions

Right atrium: receives deoxygenated blood from the body
Right ventricle: pumps deoxygenated blood to the lungs
Left atrium: receives oxygenated blood from the lungs
Left ventricle: pumps oxygenated blood around the body

Ventricles vs. Atria

The ventricles have thicker walls to pump blood over longer distances
The atria have thinner walls as these chambers only have to pump blood to the ventricles

Blood Vessels

Blood vessels are tubes that carry blood around the body
Three types of blood vessels: arteries, veins, capillaries
Arteries: carry blood away from the heart (high pressure, thick walls, elastic)
Veins: carry blood back to the heart (lower pressure, thin walls, contain valves)
Capillaries: connect arteries and veins, exchange substances

Blood Vessels (Summary Table)

Arteries: Carry blood away from the heart; high pressure, thick elastic walls
Veins: Carry blood toward the heart; lower pressure, thin walls, contain valves
Capillaries: Thin walls, connect arteries and veins, exchange substances

Blood Vessels (Types)

Arteries: carry blood away from the heart.
Veins: carry blood back to the heart.
Capillaries: carry blood to tissues
