19.Circulatory system :red_flag::+1:
What is the Circulatory System?
made out of heart, blood and blood vessels
blood vessels carry blood around the body
blood is medium of transport in body
blood is pumped
from heart to every cell
before returning to heart
heart pump blood around body
Circulaotry system transport oxygen, food and water to all parts of body
Blood from the body is pumped from the heart to
___
: and then back to the heart :!?:
what are the parts of the circulatory system
heart is a muscular organ near the middle of our chest, protected by ribcage
Every heartbeat is a cycle of contraction and expansion
With each heartbeat, a pressure wave passes along the blood vessels, known as the pulse
The faster the heart beats,the higher the pulse rate
rate of heartbeat depend on age, health and type of activity, average is 60 to 70 times/min
more intense the exersice, the faster the heartbeat
when we exersice, we need more digested food and oxygen is carried to all parts of the body
The digested food and oxygen are used for respiration in order to release enough carbon dioxide and take in oxygen
The blood flows through blood vessels
vital organ(heart) that pumps blood around our body
We cannot control the movements of heart muscle
Blood
blood transports digested food, oxygen, water, co2 and waste materials
digested food, oxygen and water to all cells
co2 and waste materials away from cells to get rid of them via lungs, kidney and skin
Blood vessels (tubes through which blood flows)
How do the organs in the circulatory System Work Together
Flow Chart : P122 &123:pencil2:
blood rich in o2 travel from lungs to heart and heart to all parts of body, blood rich in co2 travel from all cells to heart to lung
work with other systems
Respiraory System
Remove carbon dioxide and :water produced by heart cells
( circulatory systems gets o2 from respiratory system and O2 is carried by blood to all parts of the body :
Digestive System
Provides the heart and other organs with nutrients
Muscular System
Heart muscles pump blood to all parts of the body
smooth muscles located in veins and arteries push blood with each heartbeat
Difference btw Transport Systems in Animals and Plants
